Description

Technical Field

[0001] The present invention relates to the technical field of cables, and particularly to a multi-cable parallel anti-biased current cable structure. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of one or several wires. In actual electric energy transmission scenarios, if the current-carrying capacity of a single cable cannot meet the requirements, it is very likely to cause the cable to overheat, and in severe cases, it may even lead to faults such as insulation breakdown. Therefore, people usually use the method of parallel connection of multiple cables to solve this problem. However, when multiple cables are connected in parallel, a current-biasing phenomenon often occurs. At this time, in order to ensure the stability and safety of power transmission, people will use a multi-cable parallel anti-biased current cable structure.

[0003] When the existing multi-cable parallel anti-biased current cables are in use, although they can ensure that the cables in each parallel branch can evenly transmit current or signals, thereby improving the stability and reliability of the entire system, during the long-distance overhead laying process, it is not convenient to install them on the suspension wire. That is, when the multi-cable parallel anti-biased current cables are laid overhead over a long distance, construction workers generally need to first lay the cables overhead, and then use climbing equipment to continuously move along the cable laying path to evenly distribute and install the prepared installation hooks on the suspension wire. However, it is very difficult for construction workers to accurately control the spacing of each hook during the movement process, and it is easy to have an uneven distribution of hooks, which is likely to cause uneven stress on the cable, thereby affecting the service life of the cable, reducing both the use effect and the use efficiency of the multi-cable parallel anti-biased current cables.

[0004] Therefore, we propose a multi-cable parallel anti-biased current cable structure to solve the problems raised in the above background art. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-cable parallel anti-biased current cable structure to solve the problem that when the existing multi-cable parallel anti-biased current cables are in use, it is not convenient to install them on the suspension wire overhead. That is, when the multi-cable parallel anti-biased current cables are laid overhead over a long distance, construction workers generally need to first lay the cables overhead, and then use climbing equipment to continuously move along the cable laying path to evenly distribute and install the prepared installation hooks on the suspension wire. However, it is very difficult for construction workers to accurately control the spacing of each hook during the movement process, and it is easy to have an uneven distribution of hooks, which is likely to cause uneven stress on the cable, thereby affecting the service life of the cable, reducing both the use effect and the use efficiency of the multi-cable parallel anti-biased current cables.

[0006] To achieve the above object, the present invention provides the following technical solution: A multi-cable parallel anti-biased current cable structure, including a cable body, on which an installation mechanism is provided;

[0007] The installation mechanism includes an annular groove, two circular tubes, a tee pipe, a sealing plug and a card slot. Inside the annular groove, a rectangular block is fixed. Between the front surface and the rear surface of the rectangular block, two first arc-shaped blocks are fixed. Between the front surface and the rear surface of the rectangular block, a second arc-shaped block is provided. On the outer wall of the second arc-shaped block, two placement grooves are opened. At the bottom of the inner wall of one of the placement grooves, a housing is fixed. The other placement groove is movably penetrated by a U-shaped rod. A perforated block is fixed on the outer surface of the U-shaped rod. Inside the housing, two symmetrically arranged sliders are slidably connected. Inside the housing, two clamping blocks are movably sleeved. On the outer surface of each slider, a first annular groove is opened. Inside each first annular groove, a first sealing ring is provided. On the outer surface of each clamping block, a second annular groove is opened. Inside each second annular groove, a second sealing ring is provided. On the front surface of each slider, a rectangular groove is opened. A spring is provided inside the housing; By setting the installation mechanism, during the long-distance overhead laying process of the multi-cable parallel anti-biased current cable, it is convenient to be installed overhead with a suspension wire. That is, when the multi-cable parallel anti-biased current cable is laid overhead over a long distance, construction workers can install the suspension wire and the cable at equal intervals, thereby avoiding the situation that the cable is unevenly stressed, which in turn affects its service life. This not only improves the use effect of the multi-cable parallel anti-biased current cable, but also improves the use efficiency of the multi-cable parallel anti-biased current cable. When it is necessary to install the multi-cable parallel anti-biased current cable overhead with a suspension wire, at this time, with the cooperation of the prepared inflatable balloon, tee pipe and circular tube, air can be filled into the two rectangular grooves. Subsequently, with the cooperation of the housing, clamping blocks, first annular groove, first sealing ring, second annular groove and second sealing ring, the two sliders can be driven to move towards each other. Then, with the cooperation of the two sliders moving towards each other and the housing, the two clamping blocks can be driven to move towards each other.

When the clamping ends of the two clamping blocks are separated from the corresponding clamping grooves, first, by using the cooperation of the perforated block and the U-shaped rod, it is convenient to remove the second arc-shaped block from the inside of the circular ring groove. Then, by moving the second arc-shaped block, the end faces of both ends of the second arc-shaped block can be made to contact the front surface and the rear surface of the rectangular block respectively, and at the same time, the second arc-shaped block is sleeved on the outer surface of the suspension wire. After that, by using the cooperation of the perforated block, the U-shaped rod can be reset to its original position. Then, by using the cooperation of the inflatable ball, the housing, the spring resilience, and the two sliders, both clamping blocks can be driven to move back to their original positions. When the two clamping blocks are both movably clamped on the corresponding clamping grooves, by directly using the cooperation of the two placement grooves, the U-shaped rod, the two clamping blocks, the two clamping grooves, the rectangular block, the circular ring groove, and the two first arc-shaped blocks, the second arc-shaped block can be connected to the cable body. Subsequently, by operating according to the above operation steps, the overhead installation operation of the cable body and the suspension wire can be realized.

Under the action of the outer sheath layer, it can prevent various chemical substances from eroding the internal structure of the cable body, thereby extending the service life of the cable body. Under the action of the metal shielding layer, it can cancel out the external high-frequency interference electromagnetic field, thereby protecting the signal transmission inside the cable body. Under the action of the waterproof layer, when the cable body is used in an environment with high humidity, it can prevent water vapor from condensing on the surface of the cable body and penetrating into its interior, affecting the service life of the cable body. Under the action of the heat-resistant layer, when an electric arc occurs due to an electrical fault in the cable body, it can withstand the high temperature of the electric arc without being damaged. Under the action of the inner lining layer, when the cable body is subjected to external force impact, it can prevent damage to the internal structure of the cable body. Under the action of the filling layer, when the cable body is used under long-term outdoor exposure, it can reduce problems such as aging or degradation, enabling it to maintain its performance for a long time, providing a stable filling and protection effect for the cable body. Under the action of the insulating layer, it can ensure the independent electrical performance of each conductor, reduce the capacitance coupling and electromagnetic interference between conductors, thereby improving the transmission efficiency and quality of the cable body.

[0016] Preferably, a metal shielding layer is provided on the outer wall of the waterproof layer, and an outer sheath layer is provided on the outer wall of the metal shielding layer. The circular groove is formed on the outer wall of the outer sheath layer. Under the action of the conductor, the loss of electric energy during transmission can be effectively reduced. Under the action of the fixing sleeve, when the cable body is vibrated or subjected to uneven forces during installation, these forces can be absorbed and dispersed, thereby protecting the cable body and the separator from damage. Under the action of the separator, when the cable body is vibrated, impacted by external forces, or expands and contracts in volume due to temperature changes, these effects can be buffered, and the conductors can be prevented from shifting or being damaged due to mutual extrusion or collision. Under the action of the cylindrical hole, the filling layers between the grooves of the separator can be connected together, thereby increasing the mechanical stability of the internal structure of the entire cable body. Under the action of the protective layer, when the cable body is subjected to external forces such as vibration, tension, or extrusion, these external forces can be absorbed and dispersed, thereby protecting the steel wire core from damage. Under the action of the steel wire core, when the cable body is subjected to a tensile force during laying, this tensile force can be effectively resisted, preventing the cable body from being broken or overstretched.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the present invention, by providing an installation mechanism, during the long-distance overhead laying of multiple parallel anti-bias current cables, it is convenient to perform overhead installation with the suspension wire. That is, when multiple parallel anti-bias current cables are laid over a long distance, construction workers can install the suspension wire and the cables at equal distances, thereby avoiding uneven stress on the cables, which may affect their service life. This not only improves the use effect of multiple parallel anti-bias current cables but also improves their use efficiency. When it is necessary to perform overhead installation of multiple parallel anti-bias current cables with the suspension wire, first, with the cooperation of the prepared inflatable ball, tee, and round tube, air can be filled into the two rectangular grooves.

In the present invention, when the clamping ends of the two clamping blocks are separated from the corresponding clamping grooves respectively, first, by the cooperation of the perforated block and the U-shaped rod, it is convenient to remove the second arc-shaped block from the inside of the circular ring groove. Then, by moving the second arc-shaped block, the two end faces of the second arc-shaped block can be made to contact the front surface and the rear surface of the rectangular block respectively, and at the same time, the second arc-shaped block is sleeved on the outer surface of the suspension line. After that, by the cooperation of the perforated block, the U-shaped rod can be reset to its original position. Then, by the cooperation of the inflatable ball, the housing, the spring resilience and the two sliders, the two clamping blocks can be driven to move back to their original positions.

[0020] 3. In the present invention, by providing the cable body, it can ensure that the cables of each parallel branch can evenly transmit current or signals, thereby improving the stability and reliability of the entire system. Under the action of the outer sheath layer, various chemical substances can be prevented from eroding the internal structure of the cable body, thereby extending the service life of the cable body. Under the action of the metal shielding layer, the external high-frequency interference electromagnetic field can be offset, thereby protecting the signal transmission inside the cable body. Under the action of the waterproof layer, when the cable body is used in an environment with high humidity, water vapor can be prevented from condensing on the surface of the cable body and penetrating into its interior, affecting the service life of the cable body. Under the action of the heat-resistant layer, when an electric arc occurs due to an electrical fault in the cable body, the cable body can withstand the high temperature of the arc without being damaged. Under the action of the inner lining layer, when the cable body is subjected to external impact, the internal structure of the cable body will not be damaged. Under the action of the filling layer, when the cable body is used under the condition of long-term outdoor exposure, problems such as aging or degradation can be reduced, enabling it to maintain its performance for a long time, providing a stable filling and protection effect for the cable body. Under the action of the insulating layer, the electrical performance of each conductor can be ensured to be independent, reducing the capacitance coupling and electromagnetic interference between the conductors, thereby improving the transmission efficiency and quality of the cable body.

[0021] 4. In the present invention, under the action of the conductor, the power loss during power transmission can be effectively reduced. Under the action of the fixing sleeve, when the cable body is subjected to vibration or uneven forces during installation, these forces can be absorbed and dispersed, thereby protecting the cable body and the separator from damage. Under the action of the separator, when the cable body is subjected to vibration, external force impact, or volume expansion and contraction due to temperature changes, these effects can be buffered, and the conductors can be prevented from being displaced or damaged due to mutual extrusion or collision. Under the action of the cylindrical holes, the filling layers between the grooves of the separator can be connected together, thereby increasing the mechanical stability of the internal structure of the entire cable body. Under the action of the protective layer, when the cable body is subjected to external forces such as vibration, stretching, or extrusion, these external forces can be absorbed and dispersed, thereby protecting the steel wire core from damage. Under the action of the steel wire core, when the cable body is subjected to a tensile force during laying, this tensile force can be effectively resisted, preventing the cable body from being broken or overstretched.

[0033] Embodiment 1: Please refer to Figure 1 , Figure 2 , Figures 4 - 9 As shown in the figure, the present invention provides a technical solution: a multi-cable parallel anti-biased current cable structure, including a cable body 1, and an installation mechanism 2 is arranged on the cable body 1;

[0034] The installation mechanism 2 includes an annular groove 201, two circular tubes 217, a tee tube 218, a sealing plug 219, and a clamping groove 220. A rectangular block 202 is fixed inside the annular groove 201. Two first arc-shaped blocks 203 are fixed between the front surface and the rear surface of the rectangular block 202. A second arc-shaped block 204 is arranged between the front surface and the rear surface of the rectangular block 202. Two placement grooves 205 are formed in the outer wall of the second arc-shaped block 204. A housing 206 is fixed at the bottom of the inner wall of one of the placement grooves 205. A U-shaped rod 207 movably penetrates through the end surface of one end of the second arc-shaped block 204 and the side of the rectangular block 202 away from the housing 206. A perforated block 208 is fixed on the outer surface of the U-shaped rod 207. Two symmetrically arranged sliders 209 are slidably connected inside the housing 206. Two clamping blocks 210 are movably sleeved inside the housing 206. A first annular groove 211 is formed in the outer surface of each slider 209. A first sealing ring 212 is arranged inside each first annular groove 211. A second annular groove 213 is formed in the outer surface of each clamping block 210. A second sealing ring 214 is arranged inside each second annular groove 213. A rectangular groove 215 is formed in the front surface of each slider 209. A spring 216 is arranged inside the housing 206. Each first arc-shaped block 203 is located inside the annular groove 201. The second arc-shaped block 204 is located between the two first arc-shaped blocks 203. The opposite sides of the two sliders 209 are respectively fixed to the opposite sides of the two clamping blocks 210. The outer surface of each first sealing ring 212 is in contact with the inner wall of the housing 206. The outer surface of each second sealing ring 214 is in contact with the inner wall of the housing 206. The two ends of the spring 216 are respectively installed on the opposite sides of the two sliders 209. The air outlet ends of the two circular tubes 217 are respectively and fixedly penetrated through the front surface of the housing 206. The inside of each rectangular groove 215 is respectively communicated with the inside of each circular tube 217. The two air outlet ends of the tee tube 218 are respectively installed on the air inlet ends of the two circular tubes 217. The sealing plug 219 is installed at the air inlet end of the tee tube 218. Two clamping grooves 220 are respectively formed in the two connection ends of the U-shaped rod 207. The clamping ends of each clamping block 210 are respectively movably clamped inside each clamping groove 220. An outer sheath layer 113 is arranged on the outer wall of the metal shielding layer 112. The annular groove 201 is formed in the outer wall of the outer sheath layer 113.

[0035] In this embodiment, when it is necessary to install multiple parallel anti - current - deviation cables and a suspension wire overhead, first remove the sealing plug 219. Then connect the air outlet end of the prepared inflatable balloon to the air inlet end of the three - way pipe 218. Next, manually press the connected inflatable balloon. At this time, the pressed inflatable balloon will continuously inflate the inside of the three - way pipe 218. The gas continuously entering the inside of the three - way pipe 218 will respectively enter the inside of the two circular tubes 217, and then respectively enter the inside of the two rectangular grooves 215. At this time, the gas continuously entering the inside of the two rectangular grooves 215 will, under the cooperation of the housing 206, the corresponding clamping blocks 210, the corresponding first annular grooves 211, the corresponding first sealing rings 212, the corresponding second annular grooves 213, and the corresponding second sealing rings 214, respectively drive the two sliders 209 to move towards each other (at this time, the gas entering the inside of the two rectangular grooves 215 will enter the space composed of the corresponding sliders 209, the corresponding clamping blocks 210, and the housing 206). The two sliders 209 moving towards each other will, under the cooperation of the housing 206, compress the spring 216. At the same time, the two sliders 209 moving towards each other will respectively drive the two clamping blocks 210 to move towards each other. When the connecting ends of the two clamping blocks 210 are separated from the corresponding clamping slots 220, first stop pressing the inflatable balloon. Then, with the cooperation of the perforated block 208, apply a force to the U - shaped rod 207 to make the U - shaped rod 207 move away from the three - way pipe 218 until the U - shaped rod 207 is separated from the second arc - shaped block 204. Then remove the second arc - shaped block 204 from the inside of the circular ring groove 201. Next, move the removed second arc - shaped block 204 until the end faces of both ends of the second arc - shaped block 204 are respectively in contact with the front surface and the rear surface of the rectangular block 202 (as Figure 2As shown in the figure, the second arc-shaped block 204 is sleeved on the outer surface of the suspension wire at the same time. Then, with the cooperation of the perforated block 208, the U-shaped rod 207 is reset and moved. When the U-shaped rod 207 returns to its original position, the movement of the U-shaped rod 207 is stopped first. Subsequently, the inflation balloon is separated from the three-way pipe 218. At this time, both sliders 209 will move back under the cooperation of the resilience of the housing 206 and the spring 216. The two sliders 209 moving back will drive the corresponding clamping blocks 210 to move. At the same time, the two sliders 209 moving back will discharge the gas under the cooperation of the corresponding clamping blocks 210, the housing 206, the corresponding round pipes 217 and the three-way pipe 218. When the clamping ends of the two clamping blocks 210 are respectively movably clamped inside the two clamping grooves 220, at this time, the second arc-shaped block 204 can be connected to the rectangular block 202 under the cooperation of the two placement grooves 205, the U-shaped rod 207, the two clamping blocks 210 and the two clamping grooves 220. At the same time, the second arc-shaped block 204 can be connected to the cable body 1 under the cooperation of the rectangular block 202, the annular groove 201 and the two first arc-shaped blocks 203. Then, the sealing plug 219 is reset to its original position. Then, according to the above operation steps, the remaining mounting mechanisms 2 on the cable body 1 are all installed overhead with the suspension wire.

[0036] Embodiment 2: According to Figures 1 - 3 and Figure 8 As shown in the figure, the cable body 1 includes a steel wire core 101. A protective layer 102 is arranged on the outer surface of the steel wire core 101. A separator 103 is arranged on the outer wall of the protective layer 102. A plurality of cylindrical holes 104 are formed on the surface of the separator 103. A fixing sleeve 105 is arranged between the outer surfaces of the separator 103. Insulation layers 107 are arranged inside the four grooves of the separator 103. Conductors 106 are arranged inside each insulation layer 107. A filling layer 108 is arranged between the fixing sleeve 105 and the separator 103. A lining layer 109 is arranged on the outer wall of the fixing sleeve 105. A heat-resistant layer 110 is arranged on the outer wall of the lining layer 109. A waterproof layer 111 is arranged on the outer wall of the heat-resistant layer 110. A metal shielding layer 112 is arranged on the outer wall of the waterproof layer 111. An outer sheath layer 113 is arranged on the outer wall of the metal shielding layer 112.

[0037] In this embodiment, when the cable body 1 needs to be used near a chemical plant or a sewage treatment plant, etc., various chemical corrosion sources are likely to exist in its surrounding environment. At this time, under the action of the outer sheath layer 113, these chemical substances can be prevented from eroding the internal structure of the cable body 1, thereby extending the service life of the cable body 1. When there are various electromagnetic interference sources in the surrounding environment of the cable body 1, at this time, under the action of the metal shielding layer 112, the external high-frequency interference electromagnetic field can be offset, thereby protecting the signal transmission inside the cable body 1. When the cable body 1 is used in an environment with high humidity, under the action of the waterproof layer 111, water vapor can be prevented from condensing on the surface of the cable body 1 and penetrating into its interior, affecting the service life of the cable body 1. When an electric arc is generated due to an electrical fault (such as a short circuit or lightning strike, etc.) in the cable body 1, under the action of the heat-resistant layer 110, the cable body 1 can withstand the high temperature of the electric arc without being damaged. When the cable body 1 is subjected to an external impact (such as being blown by the wind and hitting the pole tower), under the action of the inner lining layer 109, the impact energy can be absorbed to protect the internal structure of the cable body 1. When the cable body 1 is used under long-term outdoor exposure, under the action of the filling layer 108, problems such as aging or degradation can be reduced, and its performance can be maintained for a long time, providing a stable filling and protection effect for the cable body 1. When the cable body 1 is in use, under the action of the insulating layer 107, the electrical performance of each conductor 106 can be ensured to be independent, reducing the capacitance coupling and electromagnetic interference between the conductors 106, thereby improving the transmission efficiency and quality of the cable body 1. When the cable body 1 is in use, under the action of the conductor 106, the power loss during the transmission process can be effectively reduced. When the cable body 1 is subjected to vibration or uneven forces during the installation process, at this time, under the action of the fixing sleeve 105, these forces can be absorbed and dispersed to protect the cable body 1 and the partition 103 from being damaged. When the cable body 1 is in operation and is subjected to vibration, external impact, or volume expansion and contraction due to temperature changes, etc., under the action of the partition 103, these effects can be buffered, and the conductors 106 can be prevented from being displaced or damaged due to mutual extrusion or collision. By means of the cylindrical hole 104, the filling layer 108 between the respective grooves of the partition 103 can be connected together, thereby increasing the mechanical stability of the entire internal structure of the cable body 1. When the cable body 1 is subjected to external forces such as vibration, tension, or extrusion, under the action of the protective layer 102, these external forces can be absorbed and dispersed to protect the steel wire core 101 from being damaged. When the cable body 1 is subjected to a tensile force during the laying process (such as when laid overhead, the self-weight of the cable and the possible wind load tensile force), under the action of the steel wire core 101, this tensile force can be effectively resisted to prevent the cable body 1 from being pulled apart or overstretched.

[0038] The effects achieved by the entire mechanism and its working principle are as follows: When it is necessary to install multiple parallel anti - deflection cables and the suspension wire overhead, first remove the sealing plug 219. Then connect the air outlet end of the prepared inflatable balloon to the air inlet end of the three - way pipe 218. Next, manually press the connected inflatable balloon. At this time, the pressed inflatable balloon will continuously inflate the inside of the three - way pipe 218. The gas continuously entering the inside of the three - way pipe 218 will respectively enter the inside of the two round pipes 217, and then enter the inside of the two rectangular grooves 215. At this time, the gas continuously entering the inside of the two rectangular grooves 215 will, under the cooperation of the housing 206, the corresponding clamping blocks 210, the corresponding first annular grooves 211, the corresponding first sealing rings 212, the corresponding second annular grooves 213, and the corresponding second sealing rings 214, drive the two sliders 209 to move towards each other respectively (at this time, the gas entering the inside of the two rectangular grooves 215 will enter the space composed of the corresponding sliders 209, the corresponding clamping blocks 210, and the housing 206). The two sliders 209 moving towards each other will, under the cooperation of the housing 206, compress the spring 216. At the same time, the two sliders 209 moving towards each other will respectively drive the two clamping blocks 210 to move towards each other. When the connecting ends of the two clamping blocks 210 are separated from the corresponding card slots 220, first stop pressing the inflatable balloon. Then, with the cooperation of the perforated block 208, apply a force to the U - shaped rod 207 to make the U - shaped rod 207 move away from the three - way pipe 218 until the U - shaped rod 207 is separated from the second arc - shaped block 204. Then remove the second arc - shaped block 204 from the inside of the circular ring groove 201. Next, move the removed second arc - shaped block 204 until the end faces of both ends of the second arc - shaped block 204 are respectively in contact with the front surface and the rear surface of the rectangular block 202 (as Figure 2As shown, while sleeving the second arc-shaped block 204 on the outer surface of the suspension line, then, with the cooperation of the perforated block 208, the U-shaped rod 207 is reset and moved. When the U-shaped rod 207 is reset to its original position, first stop the movement of the U-shaped rod 207. Subsequently, separate the inflation balloon from the three-way pipe 218. At this time, both sliders 209 will move back under the combined action of the elastic force of the housing 206 and the spring 216. The two sliders 209 moving back will drive the corresponding clamping blocks 210 to move. At the same time, the two sliders 209 moving back will, under the cooperation of the corresponding clamping blocks 210, the housing 206, the corresponding round pipes 217 and the three-way pipe 218, discharge the gas. When the clamping ends of the two clamping blocks 210 are respectively movably clamped inside the two clamping grooves 220, at this time, the second arc-shaped block 204 can be connected to the rectangular block 202 under the cooperation of the two placement grooves 205, the U-shaped rod 207, the two clamping blocks 210 and the two clamping grooves 220. At the same time, the second arc-shaped block 204 can be connected to the cable body 1 under the cooperation of the rectangular block 202, the circular ring groove 201 and the two first arc-shaped blocks 203. Then, reset the sealing plug 219 to its original position. Then, operate according to the above operation steps to overhead install the remaining installation mechanisms 2 on the cable body 1 with the suspension line. When the cable body 1 needs to be used near a chemical plant or a sewage treatment plant, etc., various chemical corrosion sources are likely to exist in its surrounding environment. At this time, under the action of the outer sheath layer 113, these chemical substances can be prevented from eroding the internal structure of the cable body 1, thereby extending the service life of the cable body 1. When there are various electromagnetic interference sources in the surrounding environment of the cable body 1, at this time, under the action of the metal shielding layer 112, the external high-frequency interference electromagnetic field can be offset, thereby protecting the signal transmission inside the cable body 1. When the cable body 1 is used in an environment with high humidity, under the action of the waterproof layer 111, water vapor can be prevented from condensing on the surface of the cable body 1 and penetrating into its interior, affecting the service life of the cable body 1. When an electric arc is generated due to an electrical fault (such as a short circuit or lightning strike, etc.) in the cable body 1, under the action of the heat-resistant layer 110, the cable body 1 can withstand the high temperature of the electric arc without being damaged. When the cable body 1 is impacted by an external force (such as being blown by the wind and hitting the pole tower), under the action of the inner lining layer 109, the impact energy can be absorbed to protect the internal structure of the cable body 1. When the cable body 1 is used in the case of long-term outdoor exposure, under the action of the filling layer 108, problems such as aging or degradation can be reduced, and its performance can be maintained for a long time, providing a stable filling and protection effect for the cable body 1. When the cable body 1 is used, under the action of the insulating layer 107, the electrical performance of each conductor 106 can be ensured to be independent, reducing the capacitance coupling and electromagnetic interference between the conductors 106, thereby improving the transmission efficiency and quality of the cable body 1. When the cable body 1 is in use, under the action of the conductor 106, the power loss during the transmission process can be effectively reduced.When the cable body 1 is subjected to vibration or uneven forces during installation, the fixing sleeve 105 can absorb and disperse these forces to protect the cable body 1 and the separator 103 from damage. When the cable body 1 is operating and is subjected to vibration, external force impacts, or volume expansion and contraction due to temperature changes, the separator 103 can buffer these effects and prevent the conductors 106 from shifting or being damaged due to mutual extrusion or collision. Through the action of the cylindrical hole 104, the filling layer 108 between the grooves of the separator 103 can be connected together, thereby increasing the mechanical stability of the internal structure of the entire cable body 1. When the cable body 1 is subjected to external forces such as vibration, tension, or extrusion, the protective layer 102 can absorb and disperse these external forces to protect the steel wire core 101 from damage. When the cable body 1 is subjected to a tensile force during laying (such as its own gravity and possible wind load tensile force during overhead laying), the steel wire core 101 can effectively resist this tensile force and prevent the cable body 1 from being broken or overstretched.

[0039] Among them, the second arc-shaped block 204 can be bent and deformed.

[0040] Among them, as Figure 1 shown, the cable body 1 is a part of the entire cable, and multiple installation mechanisms 2 are equidistantly distributed on the entire cable.

[0041] Among them, the outer sheath layer 113 is made of polyvinyl chloride material, the metal shielding layer 112 is made of aluminum foil material, the waterproof layer 111 is made of asphalt waterproof coating, the heat-resistant layer 110 is made of mica tape material, the inner liner layer 109 is made of polyolefin elastomer material, the filling layer 108 is made of glass fiber filling material, the insulating layer 107 is made of ethylene-propylene rubber material, the conductor 106 is made of copper material, the fixing sleeve 105 is made of rubber material, the separator 103 is made of silicone rubber material, the protective layer 102 is made of rubber material, and the steel wire core 101 is made of high-carbon steel wire material.

[0042] Among them, the inflation ball mentioned above is similar to the inflation ball on a sphygmomanometer, and one-way valves are installed at both the air inlet end and the air outlet end of the inflation ball. When the inflation ball is not pressed, the pressure inside the ball is lower than the external atmospheric pressure. Under the action of the pressure difference, the external air will push open one of the one-way valves and enter the ball. When the inflation ball is pressed by hand, the air inside the ball is compressed and the pressure increases. At this time, the air inside the inflation ball will enter the inside of the three-way pipe 218 through the other one-way valve.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
