Description

Technical Field

[0001] This invention relates to the field of 5G cable production technology, specifically to a cold-resistant and freeze-resistant 5G cable and its production method. Background Technology

[0002] During use, the cable's own power comes from the wind. The wind drives the outer guide plate to rotate, which is the main driving source. However, when the cable is used at high altitudes, thin ice is easily formed on its surface in winter. When the ice freezes the guide plate and increases friction, it is difficult for the wind to drive the guide plate to rotate. Once the guide plate rotates, frictional heat generation and subsequent snow removal operations cannot be performed. Chinese Patent Publication No. CN114678171B discloses "A Cold-Resistant and Freeze-Resistant 5G Cable and Its Freeze-Resistant Method". This patent includes a stretching airbag. When the push plate moves up and down to squeeze the rubber pad inside the air storage cavity, the internal space of the air storage cavity changes. After the space of the air storage cavity changes, the gas inside the stretching airbag can enter the interior of the air storage cavity through the drainage tube, thereby causing the stretching airbag to expand and contract. The contraction of the stretching airbag can pull the outer sheath inward, thereby causing the thin ice on the outer wall to break through the indentation on the surface of the outer sheath. At the same time, when the stretching airbag between adjacent heat-conducting columns causes the outer sheath to indent inward, it can further improve the fit between the outer sheath and the outer arc surface of the heat-conducting column, thereby increasing the heat conduction effect between the heat-conducting column and the outer sheath.

[0003] Existing cold-resistant and freeze-resistant 5G cables and their production methods have structural design flaws. For example, using stretching airbags to de-ice the cable can lead to poor cable rigidity and easy damage. There are also issues with how to control the temperature of 5G cables to prevent them from overheating or overcooling. Summary of the Invention

[0004] This invention provides a cold-resistant and freeze-resistant 5G cable and its manufacturing method, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cold-resistant and freeze-resistant G-type cable, comprising a through-tube, wherein a sheath is fixedly connected to the inner side of the through-tube, and a circumferential guide rail is fixedly connected to the outer surface of the through-tube, and further comprising:

[0006] A heat transfer mechanism is fixedly installed on the inner side of the sheath. A wire core is fixedly connected to the inner side of the heat transfer mechanism. The wire core is composed of copper stranded wire and cross-linked polyethylene tube. There are six wire cores. A connecting tube is fixedly connected to the top of the heat transfer mechanism. The heat transfer mechanism is used for blocking and centering multiple wire cores and for heat transfer and conduction on the surface of the wire cores.

[0007] The inner side of the circumferential guide rail is slidably connected to a wire harness assembly, and the inner side of the wire harness assembly is connected to an elastic strip via friction. A scraping assembly is fixedly connected to the end of the elastic strip away from the wire harness assembly. A pressing block is pressed together by friction on the surface of the sheath near the through tube. A protective cover is fixedly connected to the surface of the pressing block. An arc-shaped hole is opened on the side of the protective cover near the pressing block. The wire harness assembly is used for adjusting the extension and retraction of the elastic strip, and the scraping assembly is used for scraping away and breaking the thin ice on the surface of the sheath.

[0008] Preferably, the wire harness assembly includes a slider that is slidably mounted on the inner side of a circumferential guide rail, and a sphere is rotatably connected to the surface of the slider, the surface of the sphere being in close contact with the inner side of the circumferential guide rail.

[0009] Preferably, a sleeve is fixedly connected to the top of the slider, a fixing plate is fixedly connected to the surface of the sleeve, a motor is fixedly connected to the surface of the fixing plate, a friction wheel is fixedly connected to the output end of the motor, a 5G cable is fixedly installed on the top of the insulator, a fixing plate fixes the bottom of the insulator to the top of the support base, the support base is positioned above the surface of the power tower, the insulator provides insulation and protection support for the entire ice-breaking mechanism, a rubber sheath covers the outer surface of the heat transfer mechanism, two upper and lower clamping blocks move relative to each other and are fastened by bolts, and the inner side of the clamping block presses and positions the outer surface of the sheath.

[0010] Preferably, the inner side of the sleeve is slidably connected to the surface of the elastic strip, and an opening is provided on the surface of the sleeve, through which the surface of the friction wheel passes in close contact with the surface of the elastic strip.

[0011] Preferably, the scraping assembly includes a connecting ring, the side of which is fixedly mounted on the end of the elastic strip away from the friction wheel, and an inner groove is formed on the side of the connecting ring away from the elastic strip.

[0012] Preferably, the scraping assembly further includes a slider, the surface of which is slidably mounted on the connecting ring near the inner groove. A spring strip is fixedly connected to the surface of the slider, and a sliding groove is provided on the inner side of the circumferential guide rail. The ball rolls inside the sliding groove, and rolling friction replaces sliding friction, making it easier for the slider to move on the inner side of the circumferential guide rail. The ice layer near the protective cover is more easily broken. The torsion of the spring strip promotes the movement of the slider to break the ice. The sleeve provides sliding support for the elastic strip. The motor drives the friction wheel to rotate, and the friction wheel causes the elastic strip to move closer to the circumferential guide rail through friction.

[0013] Preferably, the heat transfer mechanism includes a heat shrink tubing, which is fixedly installed on the inner side of the sheath. A flow guiding component is fixedly connected to the inner side of the heat shrink tubing, a centering component is fixedly connected to the inner side of the flow guiding component, and a hemp rope is fixedly connected to the inner side of the centering component.

[0014] Preferably, the heat transfer mechanism further includes an embedded tube, which is fixedly installed on the surface of the heat shrink tubing. A bend is fixedly connected to the inner side of the embedded tube, and a fixing seat is fixedly connected to the upper part of the bend. Multiple wire cores are positioned and blocked by a centering component. A flow guiding component is disposed between the centering component and the heat shrink tubing. The flow guiding component forms a spiral airflow channel structure. The bend guides the cooling gas into the interior of the airflow channel. As the cooling gas is introduced and discharged, the heat of the wire cores is timely discharged through the centering component and the cooling gas, thereby preventing the cable from overheating. A connecting pipe is used to supply gas to multiple bends, which facilitates the control of multiple cables.

[0015] Preferably, the flow guiding assembly includes a spring sheet, the outer surface of which is fixedly mounted on the inner side of the heat shrink tubing, a plastic strip is passed through and fixedly connected to the inner side of the spring sheet, and a rubber strip is fixedly connected to the inner side of the spring sheet.

[0016] Preferably, the centering component includes a rubber tube, with a hot melt adhesive strip fixedly connected to the outer surface of the rubber tube. An injection hole is provided on the surface of the rubber tube, and a heat-conducting wire is fixedly connected to the surface of the rubber tube. The core of the 5G cable emits heat. When the external temperature is too high, the heat from the core cannot dissipate, causing the entire cable to overheat. In this device, a soft inner tube ensures a sealed connection between the bend and the sheath. The heat-conducting wire is tightly fixed to the surface of the rubber tube by threading. The connection of the heat-conducting wire allows for rapid heat transfer between the inside and outside of the rubber tube. The hot melt adhesive strip quickly bonds with the rubber strip during heating.

[0017] Preferably, the centering component further includes a plastic plate, the surface of which is fixedly mounted on the inner side of the rubber tube. A plastic tube is fixedly connected to the side of the plastic plate away from the rubber tube. The inner side of the spring strip is in contact with the surface of the sheath. When the surface of the sheath is covered with ice, the material is easily corroded and aged. In this device, the position of the sheath away from the circumferential guide rail is easily pushed and swayed by the wind. Through the elastic absorption and release of the local elastic strip, the slider can easily slide on the inner side of the circumferential guide rail, thereby promoting the breaking of the ice layer around the protective cover. Multiple plastic strips penetrate the spring sheet, and the support of the spring sheet and the plastic strips makes the overall structure of the cable more resistant to deformation.

[0018] A method for producing a cold-resistant and freeze-resistant 5G cable includes the following steps:

[0019] Step 1: Core manufacturing. At room temperature, copper rods are drawn into copper wires. The copper wires are heated and kept at that temperature, and then cooled naturally. The copper wires are twisted together using multiple single wires to form copper stranded wires. The copper stranded wires to be coated are pulled into the injection molding extrusion machine to be coated with cross-linked polyethylene, thus completing the preparation of the copper conductor core. The same process is used to complete the preparation of six cores.

[0020] Step 2: Centering structure installation. Plastic and rubber granules are fed into the injection molding extruder. The hot melt plastic is formed into a plastic sheet and plastic tube structure through the die. The heat-conducting wire is passed through the rubber tube in sequence. The rubber tube is placed on the outside of the plastic structure. Multiple wire cores and hemp rope are passed through the inside of the rubber tube in sequence. The plastic sheet blocks and positions the multiple wire cores.

[0021] Step 3: Injection molding. Silicone coating is injected into the injection hole. Multiple plastic strips are passed through the inner side of the spring sheet in sequence and fixed by heat melting. The inner side of the rubber strip is in direct contact with the surface of the heat melt strip, which heats the surface of the spring sheet, so that the spring sheet is quickly fixed. The heat shrink tube passes through the outer surface of the spring sheet and heats the overall structure. The heat shrink tube is heat-shrinked and wrapped. The wrapped tubular structure is pulled to the extrusion wrapping machine to form the protective sleeve.

[0022] Step 4: Ice-breaking structure installation. Insert the through tube into the outer surface of the sheath. Pull the elastic strip into the inside of the wire harness assembly for clamping and limiting. Move the two protective covers and the clamping block relative to each other so that the sheath is fixedly installed near the through tube. Fix the fixing components to the end faces of the multiple elastic strips to complete the overall installation of the ice-breaking structure.

[0023] This invention provides a cold-resistant and freeze-resistant 5G cable and its manufacturing method. It has the following beneficial effects:

[0024] 1. The cold-resistant and freeze-resistant 5G cable and its production method: the sheath between the two protective covers is subjected to gravity and wind force. In cold weather, the surface of the sheath and the protective cover are covered with ice. The wind blows the sheath to swing slowly. The single elastic strip absorbs the elastic potential energy and promotes the swing of multiple elastic strips. The cable bundle assembly slides on the inner side of the circumferential guide rail to promote the ice layer to break. It replaces airbags and other structures to break ice and solves the problem that using stretching airbags to de-ice the cable will cause the cable itself to have poor rigidity and be easily damaged.

[0025] 2. The cold-resistant and freeze-resistant 5G cable and its production method: The elastic strip is pulled away from the spring strip, the pitch of the spring strip increases, and the diameter of the spring strip decreases. Initially, the inner side of the spring strip is at a certain distance from the surface of the sheath. After the spring strip is stretched, it moves and contacts the surface of the sheath, so that the ice layer on the surface of the sheath is quickly broken. The stretching, contraction and torsion of the elastic strip promote the movement of the spring strip, and also promote the movement of the slider, thereby increasing the overall de-icing efficiency of the cable.

[0026] 3. This cold-resistant and freeze-resistant 5G cable and its production method: In cold weather, ambient temperature gas is introduced into the cable through a bend in the pipe. The heat of the core is conducted to the flowing ambient temperature gas, and the temperature is transferred to the sheath as the gas flows. The increased temperature of the sheath helps to break the ice layer. With the help of wind, the sheath swings, and the cable bundle assembly and scraping assembly promote the breaking of the ice layer on the entire cable. Combined with the increase in the temperature of the sheath, this solves the problem of how to control the temperature of the 5G cable to prevent the cable from overheating or overcooling.

[0027] 4. The cold-resistant and freeze-resistant 5G cable and its production method involve injecting silicone into the rubber tube through the injection hole. The silicone allows multiple cores and hemp rope to be quickly positioned. The hemp rope prevents the cores from shifting when compressed. The heat-conducting wire quickly transfers the heat of the cores to the outside of the rubber tube. When cooling gas flows on the surface of the spring sheet, the heat of the cores is quickly carried away to prevent the cable from overheating. In cold weather, the gas flowing through the spring sheet helps to transfer heat to the sheath, preventing the cable from overheating while making full use of the heat of the cores.

[0028] 5. The cold-resistant and freeze-resistant 5G cable and its production method: When the two opposing connecting rings are pulled away, the pitch of the spring strip increases and the diameter decreases. The sliding body slides towards the axis in the inner groove. The ice layer deposited on the sheath surface is easily broken under the pressure of the spring strip. At the same time, as the heat of the wire core is transferred to the spring sheet through the heat of the wire core, the temperature of the sheath surface rises, avoiding the aging and embrittlement of the material at low temperature, thus effectively improving the cold and heat resistance of the cable.

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] First embodiment: as follows Figures 1-5 As shown, the present invention provides a technical solution: a cold-resistant and freeze-resistant 5G cable, including a through-tube 41, a sheath 5 fixedly connected to the inner side of the through-tube 41, and a circumferential guide rail 42 fixedly connected to the outer surface of the through-tube 41, and further including:

[0042] Heat transfer mechanism 6 is fixedly installed on the inner side of the sheath 5. A wire core 7 is fixedly connected to the inner side of the heat transfer mechanism 6. The wire core 7 is composed of copper stranded wire and cross-linked polyethylene tube. There are six wire cores 7. A connecting pipe 8 is fixedly connected to the top of the heat transfer mechanism 6. The heat transfer mechanism 6 is used for the isolation and centering of multiple wire cores 7 and for the heat transfer and conduction of the surface of the wire core 7.

[0043] The inner side of the circumferential guide rail 42 is slidably connected to a wire harness assembly 46. The inner side of the wire harness assembly 46 is connected to an elastic strip 47 by friction. The end of the elastic strip 47 away from the wire harness assembly 46 is fixedly connected to a scraping assembly 48. The surface of the sheath 5 is close to the through tube 41 and a pressing block 45 is pressed together by friction. The surface of the pressing block 45 is fixedly connected to a protective cover 43. An arc-shaped hole 44 is opened on the side of the protective cover 43 close to the pressing block 45. The wire harness assembly 46 is used for the extension and retraction adjustment of the elastic strip 47, and the scraping assembly 48 is used for scraping away and breaking the thin ice on the surface of the sheath 5.

[0044] In use, the 5G cable is fixedly installed on the top of the insulator 3, and the fixing plate 2 fixes the bottom of the insulator 3 to the top of the support base 1. The support base 1 is set above the surface of the power tower. The insulator 3 provides insulation and protection for the ice-breaking mechanism 4. The rubber sheath 5 covers the outer surface of the heat transfer mechanism 6. The two pressing blocks 45 at the upper and lower positions move relative to each other and are fastened by bolts. The inner side of the pressing block 45 presses and positions the outer surface of the sheath 5. The sheath 5 between the two protective covers 43 is subjected to gravity and wind force. In cold weather, the surface of the sheath 5 and the protective cover 43 are covered with ice. The wind blows the sheath 5 to swing slowly. The single elastic strip 47 absorbs elastic potential energy and promotes the swing of multiple elastic strips 47. The cable bundle assembly 46 slides on the inner side of the circumferential guide rail 42 to promote the ice layer to break. It replaces the airbag and other structures for ice breaking and solves the problem that using the stretching airbag to de-ice the cable will cause the cable itself to have poor rigidity and be easily damaged.

[0045] Second embodiment: as follows Figures 4-7 As shown, the wire harness assembly 46 includes a slider 461, which is slidably mounted on the inner side of the circumferential guide rail 42. A ball 462 is rotatably connected to the surface of the slider 461, and the surface of the ball 462 is in close contact with the inner side of the circumferential guide rail 42. A sleeve 463 is fixedly connected to the top of the slider 461, and a fixing plate 464 is fixedly connected to the surface of the sleeve 463. A motor 465 is fixedly connected to the surface of the fixing plate 464, and a friction wheel 466 is fixedly connected to the output end of the motor 465. The inner side of the sleeve 463 is slidably connected to the surface of the elastic strip 47. An opening is provided on the surface of the sleeve 463, and the surface of the friction wheel 466 passes through the opening and is in close contact with the surface of the elastic strip 47.

[0046] The scraping assembly 48 includes a connecting ring 481. The side of the connecting ring 481 is fixedly installed on the end of the elastic strip 47 away from the friction wheel 466. An inner groove 482 is provided on the side of the connecting ring 481 away from the elastic strip 47. The scraping assembly 48 also includes a sliding body 483. The surface of the sliding body 483 is slidably installed on the connecting ring 481 near the inner groove 482. A spring strip 484 is fixedly connected to the surface of the sliding body 483.

[0047] In use, the inner surface of the circumferential guide rail 42 is provided with a sliding groove. The ball 462 rolls inside the sliding groove, and the rolling friction replaces the sliding friction, making it easier for the slider 461 to move on the inner surface of the circumferential guide rail 42. The ice layer near the protective cover 43 is more easily broken. The torsion of the spring bar 484 promotes the movement of the slider 461 to break the ice. The sleeve 463 provides sliding support for the elastic bar 47. The motor 465 drives the friction wheel 466 to rotate. The friction wheel 466 uses friction to make the elastic bar 47 move closer to the circumferential guide rail. As spring bar 47 moves away from spring bar 484, the pitch of spring bar 484 increases and its diameter decreases. Initially, the inner side of spring bar 484 is at a certain distance from the surface of sheath 5. After spring bar 484 is stretched, it moves relative to the surface of sheath 5, causing the ice layer on the surface of sheath 5 to be quickly broken. The extension, contraction and torsion of elastic bar 47 promote the movement of spring bar 484 and also promote the movement of slider 461, thereby increasing the overall de-icing efficiency of the cable.

[0048] Third embodiment: as follows Figure 4 , Figure 8 As shown, a wire harness assembly 46 is slidably connected to the inner side of the circumferential guide rail 42. An elastic strip 47 is connected to the inner side of the wire harness assembly 46 by friction. A scraping assembly 48 is fixedly connected to the end of the elastic strip 47 away from the wire harness assembly 46. A pressing block 45 is pressed together by friction on the surface of the sheath 5 near the through tube 41. A protective cover 43 is fixedly connected to the surface of the pressing block 45. An arc-shaped hole 44 is opened on the side of the protective cover 43 near the pressing block 45. The wire harness assembly 46 is used for the extension and retraction adjustment of the elastic strip 47, and the scraping assembly 48 is used for scraping away and breaking the thin ice on the surface of the sheath 5.

[0049] The heat transfer mechanism 6 includes a heat shrink tubing 61, which is fixedly installed on the inner side of the sheath 5. A flow guiding component 62 is fixedly connected to the inner side of the heat shrink tubing 61, a centering component 63 is fixedly connected to the inner side of the flow guiding component 62, and a hemp rope 64 is fixedly connected to the inner side of the centering component 63. The heat transfer mechanism 6 also includes an embedded tube 65, which is fixedly installed on the surface of the heat shrink tubing 61. A bend 66 is fixedly connected to the inner side of the embedded tube 65, and a fixing seat 67 is fixedly connected to the upper part of the surface of the bend 66.

[0050] In use, multiple cores 7 are positioned and blocked by the centering component 63. The flow guiding component 62 is located between the centering component 63 and the heat shrink tubing 61. The flow guiding component 62 forms a spiral airflow channel structure. The bend 66 introduces cooling gas into the interior of the airflow channel. As the cooling gas is introduced and discharged, the heat of the cores 7 is promptly discharged through the centering component 63 and the cooling gas, thereby preventing the cable from overheating. The connecting pipe 8 is used to supply gas to multiple bends 66, which facilitates the control of multiple cables. In cold weather, room temperature gas is introduced into the interior of the cable through the bend 66. The heat of the cores 7 is conducted to the flowing room temperature gas. As the gas flows, the temperature is transferred to the sheath 5. The temperature rise of the sheath 5 helps to break the ice layer. With the help of wind, the sheath 5 swings. The cable bundle component 46 and the scraping component 48 promote the breaking of the ice layer of the entire cable. With the increase in the temperature of the sheath 5, the problem of how to control the temperature of the 5G cable to prevent the cable from overheating or overcooling is solved.

[0051] Fourth embodiment: as Figure 6 , Figure 7 , Figure 8 As shown, the flow guiding component 62 includes a spring sheet 621, the outer surface of which is fixedly mounted on the inner side of the heat shrink tubing 61. A plastic strip 622 is passed through and fixedly connected to the inner side of the spring sheet 621, and a rubber strip 623 is fixedly connected to the inner side of the spring sheet 621. The centering component 63 includes a rubber tube 631, a hot melt adhesive strip 632 is fixedly connected to the outer surface of the rubber tube 631, an injection hole 633 is opened on the surface of the rubber tube 631, and a heat-conducting wire 634 is fixedly connected to the surface of the rubber tube 631.

[0052] The centering component 63 also includes a plastic plate 635, the surface of which is fixedly installed on the inner side of the rubber tube 631, and a plastic tube 636 is fixedly connected to the side of the plastic plate 635 away from the rubber tube 631.

[0053] During use, the core 7 inside the 5G cable dissipates heat. When the external temperature is too high, the heat from the core 7 cannot dissipate, causing the entire cable to overheat. In this device, the soft inner tube 65 ensures a sealed connection between the bend 66 and the sheath 5. The heat-conducting wire 634 is tightly fixed to the surface of the rubber tube 631 by threading. The connection of the heat-conducting wire 634 allows for rapid heat transfer between the inside and outside of the rubber tube 631. The hot melt adhesive strip 632 quickly bonds with the rubber strip 623 during heating, and heat is transferred through the injection hole 633 to the rubber strip 623. Silicone is introduced into the inside of the rubber tube 631. The silicone allows multiple wire cores 7 and hemp rope 64 to be quickly positioned. The hemp rope 64 prevents the wire cores 7 from shifting when compressed. The heat-conducting wire 634 quickly transfers the heat of the wire cores 7 to the outside of the rubber tube 631. When cooling gas flows on the surface of the spring plate 621, the heat of the wire cores 7 is quickly carried away to prevent the cable from overheating. In cold weather, the gas flowing through the spring plate 621 helps to transfer heat to the sheath 5, preventing the cable from overheating while making full use of the heat of the wire cores 7.

[0054] Fifth embodiment: as follows Figure 7 , Figure 9 , Figure 10 As shown, the side of the connecting ring 481 is fixedly installed on the end of the elastic strip 47 away from the friction wheel 466. The side of the connecting ring 481 away from the elastic strip 47 has an inner groove 482. The scraping assembly 48 also includes a sliding body 483. The surface of the sliding body 483 is slidably installed on the connecting ring 481 near the inner groove 482. A spring strip 484 is fixedly connected to the surface of the sliding body 483.

[0055] The outer surface of the spring sheet 621 is fixedly installed on the inner side of the heat shrink tubing 61. A plastic strip 622 is passed through and fixedly connected to the inner side of the spring sheet 621. A rubber strip 623 is fixedly connected to the inner side of the spring sheet 621. The centering assembly 63 includes a rubber tube 631. A hot melt adhesive strip 632 is fixedly connected to the outer surface of the rubber tube 631. An injection hole 633 is opened on the surface of the rubber tube 631. A heat-conducting wire 634 is fixedly connected to the surface of the rubber tube 631.

[0056] During use, the inner side of the spring strip 484 contacts the surface of the sheath 5. When the surface of the sheath 5 is covered with ice, the material is easily corroded and aged. In this device, the position of the sheath 5 away from the circumferential guide rail 42 is easily pushed and swayed by the wind. Through the elastic absorption and release of the local elastic strip 47, the slider 461 can easily slide on the inner side of the circumferential guide rail 42, thereby promoting the breaking of the ice layer around the protective cover 43. Multiple plastic strips 622 penetrate the spring plate 621. The support of the spring plate 621 and the plastic strips 622 makes the electric The overall cable structure has stronger resistance to deformation. When the two opposing connecting rings 481 are pulled away, the pitch of the spring strip 484 increases and the diameter decreases. The sliding body 483 slides towards the axis at the position of the inner groove 482. The ice layer deposited on the surface of the sheath 5 is easily broken under the pressure of the spring strip 484. At the same time, as the heat of the core 7 is transferred to the spring plate 621 through the core 7, the temperature of the surface of the sheath 5 rises, which prevents the material from aging and becoming brittle at low temperatures, thus effectively improving the cold and heat resistance of the cable.

[0057] Sixth embodiment: as follows Figures 1-10 As shown, a method for producing a cold-resistant and freeze-resistant 5G cable includes the following steps:

[0058] Step 1: Core manufacturing. At room temperature, copper rods are drawn into copper wires. The copper wires are heated and kept at a high temperature, and then cooled naturally. The copper wires are stranded by twisting multiple single wires to form copper stranded wires. The copper stranded wires to be coated are pulled into the injection molding extrusion machine to be coated with cross-linked polyethylene, thus completing the preparation of copper conductor core 7. Similarly, the preparation of six cores 7 is completed.

[0059] Step 2: Centering structure installation. Plastic and rubber granules are fed into the injection molding extruder. The hot melt plastic is formed into an integral structure of plastic plate 635 and plastic tube 636 through the die. The heat-conducting wire 634 is passed through the rubber tube 631 in sequence. The rubber tube 631 is sleeved on the outside of the integral plastic structure. Multiple wire cores 7 and hemp rope 64 are passed through the inside of the rubber tube 631 in sequence. The plastic plate 635 blocks and positions the multiple wire cores 7.

[0060] Step 3: Injection molding. Silicone coating is injected into the injection hole 633. Multiple plastic strips 622 are sequentially inserted through the inner side of the spring sheet 621 and fixed by heat melting. The inner side of the rubber strip 623 is in direct contact with the surface of the heat melt strip 632, which heats the surface of the spring sheet 621, so that the spring sheet 621 is quickly fixed. The heat shrink tube 61 passes through the outer surface of the spring sheet 621 to heat the overall structure. The heat shrink tube 61 is heat-shrinked and wrapped. The wrapped tubular structure is pulled to the extrusion wrapping machine forming sleeve 5.

[0061] Step 4: Ice-breaking structure installation. Insert the through tube 41 into the outer surface of the sheath 5. Pull the elastic strip 47 into the inside of the wire harness assembly 46 for clamping and limiting. Move the two protective covers 43 and the clamping block 45 relative to each other, so that the sheath 5 is fixedly installed near the through tube 41. Fix the fixing assembly 48 to the end face of the multiple elastic strips 47 to complete the overall installation of the ice-breaking structure.
