Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage line maintenance, and specifically, to a telescopic insulating rod. Background Art

[0002] In the daily operation and maintenance of high-voltage conductors, it is crucial to ensure the safe and stable operation of the conductors. However, since high-voltage conductors are usually erected at a relatively high position and the surrounding environment is complex, they are easily affected by various foreign objects. For example, foreign objects such as plastic bags and tree branches may be blown onto high-voltage conductors. If not cleaned in time, it will have a serious impact on power transmission and may even cause safety accidents.

[0003] Traditional tools for cleaning foreign objects on high-voltage conductors have many deficiencies. On the one hand, their lengths are often fixed and cannot adapt to high-voltage conductors at different heights. As a result, when operators clean foreign objects at higher positions, they have to get closer to the high-voltage conductors, greatly increasing the risk of operation. On the other hand, the connecting piece structure of traditional tools is simple. During use, the cleaning piece is prone to uncontrollable rotation, with poor stability, affecting the cleaning effect, and is easily separated when subjected to external forces or shaking, making it difficult to carry out the cleaning work continuously.

[0004] In addition, the cleaning pieces of traditional cleaning tools are designed in a single way and cannot well adapt to the cleaning requirements of different types of foreign objects, resulting in low cleaning efficiency. In the actual scenario of high-voltage conductor maintenance, there is an urgent need for a tool that can effectively clean high-voltage conductors at different heights from a safe distance to improve the operation safety and cleaning efficiency.

[0054] Embodiment 1

[0055] Referring to Figures 1 to 3 , which is the first embodiment of the present utility model, a telescopic insulating rod is proposed, including a telescopic rod 1, a first connecting member 2 is arranged at the end of the telescopic rod 1, the first connecting member 2 has a mounting hole 201, the mounting hole 201 has a limiting portion 202, a second connecting member 3, the second connecting member 3 is slidably arranged in the mounting hole 201, the second connecting member 3 has a limiting groove 301, after the second connecting member 3 slides and slides into or out of the mounting hole 201, the limiting groove 301 is used to accommodate the limiting portion 202, and the second connecting member 3 is arranged at the end of the cleaning member 4.

[0056] In this embodiment, the telescopic rod 1 can be adjusted in length according to the height of the high-voltage conductor. A first connector 2 is positioned at the end of the telescopic rod 1, with a mounting hole 201 and a stopper 202 thereon mating with a second connector 3. The second connector 3 slides within the mounting hole 201 and includes a stopper 301. When cleaning is required, the second connector 3 is slid into the mounting hole 201, allowing the stopper 202 to enter the stopper 301 to secure the connection. Compared to traditional quick connectors, the design of the stopper 202 and the stopper 301 prevents uncontrolled rotation of the cleaning member 4 during use. The cleaning member 4 is positioned at the end of the second connector 3 and is specifically designed to remove foreign matter from the high-voltage conductor. In actual high-voltage conductor maintenance scenarios, if foreign matter, such as a plastic bag or a branch, is found hanging from the high-voltage conductor, the operator can accurately insert the second connector 3 into the mounting hole 201 of the first connector 2, ensuring that the stopper 202 and the stopper 301 fit properly. The telescopic rod 1 is then extended to a height close to the conductor. By operating the telescopic rod 1, the cleaning member 4 is brought close to the foreign objects on the high-voltage wire, and the special design of the cleaning member 4 is used to clean the foreign objects off. Near the high-voltage substation, plastic bags blown by the wind are entangled on the high-voltage wires. At this time, using this telescopic insulating rod can quickly and effectively clean up the foreign objects while ensuring a safe distance, avoiding affecting the power transmission. For the specific purpose of cleaning foreign objects on high-voltage wires, the telescopic rod 1 design of the telescopic insulating rod enables operators to clean high-voltage wires at different heights from a safe distance, greatly improving the safety of the operation. The connection method of the first connecting member 2 and the second connecting member 3 ensures the stability of the cleaning member 4 during the cleaning process, and it will not be easily separated due to shaking or external force, ensuring the continuity and effectiveness of the cleaning work. The specially designed cleaning member 4 can better adapt to the cleaning needs of foreign objects on high-voltage wires and improve cleaning efficiency. Cleaning members 4 of different shapes and materials can be selected according to different types of foreign objects, which enhances the practicality of the telescopic insulating rod.

[0057] Furthermore, the second connecting member 3 also has a card slot 302, the first connecting member 2 includes a mounting portion 203, the mounting portion 203 has a mounting hole 201, the mounting portion 203 also has a through hole 208, the mounting portion 203 has an annular groove 204, the through hole 208 is connected to the annular groove 204, the card bead 205 is slidably set in the through hole 208, and is engaged with the card slot 302, the sliding member 206 is slidably set on the mounting portion 203, the sliding member 206 has a clearance groove 207 and a guide surface 209, after the sliding member 206 slides, the card bead 205 slides in the through hole 208, cancels the abutment with the card slot 302 and abuts with the clearance groove 207, when the sliding member 206 is reset, the card bead 205 is engaged with the card slot 302 through the guide surface 209, one end of the elastic member 210 acts on the mounting portion 203, and the other end acts on the sliding member 206, providing a force for the card bead 205 to be engaged in the card slot 302.

[0058] In this embodiment, the second connecting member 3 further has a card slot 302. The first connecting member 2 includes a mounting portion 203, a detent ball 205, a sliding member 206 and an elastic member 210. The mounting portion 203 has a mounting hole 201, a through hole 208 and an annular groove 204, and the through hole 208 communicates with the annular groove 204. The detent ball 205 is slidably disposed in the through hole 208 and is engaged with the card slot 302 of the second connecting member 3. The sliding member 206 is slidably disposed on the mounting portion 203 and has a relief groove 207 and a guiding surface 209. When the sliding member 206 slides, the detent ball 205 slides in the through hole 208, cancels the abutment with the card slot 302 and abuts against the relief groove 207. At this time, the second connecting member 3 can be pulled out of or inserted into the mounting hole 201. When the sliding member 206 is reset, the detent ball 205 is engaged with the card slot 302 through the guiding surface 209, thereby fixing the second connecting member 3. One end of the elastic member 210 acts on the mounting portion 203, and the other end acts on the sliding member 206, providing a force for the detent ball 205 to snap into the card slot 302.

[0059] In practical applications, when it is necessary to install the cleaning member 4 on the telescopic rod 1, the second connecting member 3 is inserted into the mounting hole 201 of the mounting portion 203. During the insertion process, the end of the second connecting member 3 pushes the detent ball 205, causing the detent ball 205 to slide in the through hole 208. When the detent ball 205 slides to the position of the card slot 302, under the action of the elastic member 210, the detent ball 205 snaps into the card slot 302, realizing the connection and fixation between the second connecting member 3 and the first connecting member 2. When it is necessary to disassemble the cleaning member 4, the sliding member 206 is slid to cancel the abutment between the detent ball 205 and the card slot 302 and abut against the relief groove 207. At this time, the second connecting member 3 can be pulled out of the mounting hole 201. During the high-voltage wire foreign object cleaning operation, the cleaning member 4 is damaged during use and needs to be replaced. The operator can quickly disassemble the second connecting member 3 and the cleaning member 4 by sliding the sliding member 206, then replace the new cleaning member 4 and install it on the telescopic rod 1 to continue the cleaning operation. The cooperation between the detent ball 205 and the card slot 302 and the design of the sliding member 206 and the elastic member 210 make the connection and disassembly between the second connecting member 3 and the first connecting member 2 more convenient and fast. During the high-voltage wire foreign object cleaning operation, the cleaning member 4 can be quickly replaced, improving the work efficiency. The force provided by the elastic member 210 can ensure that the detent ball 205 always maintains the engaged state with the card slot 302, preventing the second connecting member 3 from accidentally falling off during the cleaning operation, ensuring the safety and stability of the cleaning work. The design of the relief groove 207 and the guiding surface 209 of the sliding member 206 makes the sliding of the detent ball 205 smoother and the operation easier. At the same time, it also improves the engagement accuracy and reliability between the detent ball 205 and the card slot 302.

[0060] Further, the cleaning member 4 includes a connecting column 401, the second connecting member 3 is disposed at the end of the connecting column 401, an extension column 402 is disposed on the connecting column 401, and a plurality of cleaning columns 403 are arranged on the extension column 402 for cleaning materials with relatively high material strength.

[0061] In this embodiment, the connecting column 401 plays a key connecting role. The second connecting member 3 is firmly disposed at the end of the connecting column 401 to ensure a stable connection between the cleaning member 4 and the telescopic rod 1. When foreign objects on the high-voltage wire need to be cleaned, the length is adjusted by the telescopic movement of the telescopic rod 1, so that the cleaning member 4 can accurately reach the target position. The extension column 402 provides a larger operating range for the cleaning work. It is disposed on the connecting column 401 and can be adjusted or fixed in length according to actual needs. When facing high-voltage wires at different heights and positions, the extension column 402 can make the cleaning column 403 closer to the foreign objects, improving the cleaning effect and efficiency. The cleaning column 403 is an important part dedicated to cleaning materials with relatively high material strength. A plurality of cleaning columns 403 are arranged on the extension column 402, and the foreign objects can be cleaned from different angles and directions. For example, when encountering foreign objects with relatively high strength such as metal wires and plastic tapes wound around the high-voltage wire, the cleaning column 403 can separate the foreign objects from the wire by means of scraping, pulling, squeezing, etc. During the maintenance of a high-voltage transmission line, the staff found that a hard plastic tape was tightly wound around the high-voltage wire. At this time, using this telescopic insulating rod, the telescopic rod 1 was extended to an appropriate length to make the cleaning column 403 close to the plastic tape. Due to the special design and arrangement of the cleaning column 403, it can effectively grasp the plastic tape and gradually clean it from the wire without damaging the wire. The connecting column 401 ensures a reliable connection between the cleaning member 4 and the telescopic rod 1, making the entire cleaning process more stable and safe. During the operation, the cleaning member 4 will not fall off due to insecure connection, thus avoiding possible safety accidents. The presence of the extension column 402 increases the flexibility and adaptability of the cleaning member 4. It can be adjusted according to different working requirements, enabling the cleaning column 403 to better cope with various complex cleaning situations. Whether it is a wire at a high place or a difficult-to-reach position, the extension column 402 can provide strong support for the cleaning work. The design of the cleaning column 403 has significant advantages for materials with relatively high material strength. The arrangement of multiple cleaning columns 403 can increase the contact area with the foreign objects, improving the cleaning strength and efficiency. At the same time, the material and shape of the cleaning column 403 can be selected and optimized according to different types of foreign objects to achieve the best cleaning effect.

[0062] Embodiment 2

[0063] Refer to Figure 4 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is:

[0064] Compared with the first embodiment, further, the cleaning member 4 includes a mounting post 404. The mounting post 404 is arranged on the connecting post 401. The mounting post 404 is a spiral column, and cleaning bristles 405. A plurality of cleaning bristles 405 are grouped together, and several groups of cleaning bristles 405 are arranged on the spiral column.

[0065] In this embodiment, there are also included a mounting post 404 and cleaning bristles 405. The mounting post 404 is arranged on the connecting post 401, and the mounting post 404 is a spiral column. A plurality of cleaning bristles 405 are grouped together, and several groups of cleaning bristles 405 are arranged on the spiral column. In practical applications, when cleaning foreign objects on a high-voltage wire, the cleaning member 4 is extended to near the wire through the telescopic rod 1. The spiral mounting post 404 can better adapt to the shape of the wire and increase the contact area with the wire. At the same time, several groups of cleaning bristles 405 can clean the foreign objects on the wire from different angles. If there are relatively soft foreign objects such as dust, spider webs or thin plastic films on the wire, the cleaning bristles 405 can remove them by gentle brushing. In the area of outdoor high-voltage transmission lines, after a period of time, there is some dust and spider webs accumulated on the wire. Using this telescopic insulating rod with a spiral mounting post 404 and cleaning bristles 405, the wire can be conveniently cleaned to keep the wire in good working condition. The design of the spiral mounting post 404 enables the cleaning bristles 405 to surround the wire more closely, improving the cleaning effect. Regardless of the diameter of the wire, the spiral structure can ensure that the cleaning bristles 405 are in full contact with the wire, effectively removing foreign objects. The arrangement of several groups of cleaning bristles 405 increases the cleaning strength and coverage. Different groups of cleaning bristles 405 can clean different parts of the wire simultaneously, improving the cleaning efficiency. Moreover, the cleaning bristles 405 can be selected with different materials and hardnesses according to needs to adapt to different types of foreign objects. The design of this cleaning member 4 combined with other parts of the telescopic insulating rod provides a convenient and efficient tool for the cleaning and maintenance of high-voltage wires. The operator can operate the cleaning member 4 through the telescopic rod 1 at a safe distance, avoiding the danger of directly contacting the high-voltage wire.

[0066] When facing fine or light materials, the cleaning bristles 405 with a spiral design exhibit unique advantages during the rotation of the insulating rod. When the bristles come into contact with the wire, due to the special nature of their spiral structure, they do not cause obvious hard scratching to the wire, but instead clean it in a relatively gentle manner. This gentle cleaning method can effectively remove light dirt such as dust and fine particles on the wire surface, while minimizing wear on the wire. Although the action of the bristles on the wire is relatively gentle, due to their special arrangement and spiral structure, when the insulating rod rotates, the bristles can quickly slide across the wire surface, covering all parts of the wire. For the fine dust and light debris attached to the wire surface, they can be efficiently cleaned to ensure that the wire surface remains clean and does not affect its electrical conductivity. When cleaning the wire, traditional cleaning tools may cause unnecessary wear to the wire due to unreasonable bristle structures, especially when cleaning fine and light materials, it is easier to cause wire damage due to over-cleaning. However, the bristles with a spiral design have a more ingenious contact method with the wire during the rotation of the insulating rod, and the friction between the bristles and the wire is relatively uniform and small, thus significantly reducing wear on the wire. Even during long-term cleaning operations, the integrity and service life of the wire can be ensured. Wires usually have a certain shape and curvature, and the spiral bristles can better adapt to these shape characteristics of the wire. During the cleaning process, the bristles can clean along the curved part of the wire without generating local excessive pressure or jamming due to the shape change of the wire, further reducing potential damage to the wire and meeting the cleaning requirements of the wire in different shapes.

[0067] Embodiment 3

[0068] Refer to Figure 5 , which is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that:

[0069] Compared with the second embodiment, further, it further includes a first breaking part 406. The first breaking part 406 is arranged on C and forms a first breaking space 407 with the extension column 402. The second breaking part 408 is arranged on the extension column 402 and is located on one side of the first breaking part 406. The first breaking part 406 and the second breaking part 408 are arranged at an obtuse angle and are smoothly connected in a transitional manner. The second breaking part 408 and the extension column 402 form a second breaking space 409. Both the first breaking space 407 and the second breaking space 409 are used for breaking branches.

[0070] In this embodiment, the first breaking portion 406 is arranged on the extension column 402, and a first breaking space 407 is formed between the first breaking portion 406 and the extension column 402. The second breaking portion 408 is arranged on the extension column 402 and on one side of the first breaking portion 406. The first breaking portion 406 and the second breaking portion 408 are arranged at an obtuse angle and are smoothly transitionally connected. The second breaking portion 408 and the extension column 402 form a second breaking space 409. Both the first breaking space 407 and the second breaking space 409 are used for breaking branches. In practical applications, when there are foreign objects such as branches near the high-voltage wire that need to be cleared, the operator can use the telescopic rod 1 to extend the cleaning member 4 to the branch. If the branch is relatively thin, it can be directly clamped into the first breaking space 407, and by rotating or applying a certain pressure, the branch can be broken under the action of the first breaking portion 406 and the extension column 402. For relatively thick branches, the branch can be first guided to the smooth transition between the first breaking portion 406 and the second breaking portion 408, and then gradually pressed into the second breaking space 409, and the branch can be broken by the combined force of the second breaking portion 408 and the extension column 402. In the high-voltage transmission line corridor, there are some branches close to the wire, which may pose a threat to the safe operation of the wire. Using this telescopic insulating rod with a breaking portion, the branches can be quickly and effectively broken and cleared, ensuring the normal operation of the high-voltage wire. The design of the first breaking portion 406 and the second breaking portion 408 provides a convenient method for clearing foreign objects such as branches. Without using other tools, the branch can be broken only through the cleaning member 4 of the telescopic insulating rod, improving the work efficiency. The first breaking portion 406 and the second breaking portion 408 arranged at an obtuse angle and smoothly transitionally connected can adapt to branches of different thicknesses. For relatively thin branches, the first breaking space 407 can quickly break them; for relatively thick branches, the second breaking space 409 provides a greater breaking force to ensure that the branches can be smoothly cleared. This design increases the versatility of the telescopic insulating rod. In addition to clearing materials with relatively high strength, it can also handle common foreign objects such as branches, expanding its application range.

[0071] Embodiment 4

[0072] Referring to Figure 6 , this is the fourth embodiment of the present utility model. The difference between this embodiment and the third embodiment is that:

[0073] Compared with the third embodiment, further, it further includes a mounting fastener 410. The mounting fastener 410 is arranged on the extension column 402, and a combustion member 411 is arranged on the mounting fastener 410 for cleaning light and small materials on the wire.

[0074] In this embodiment, the mounting fastener 410 is arranged on the extension column 402, and the combustion member 411 is arranged on the mounting fastener 410. In practical applications, when there is a need to clean light and small materials on the wire, such as plastic film fragments, catkins, etc., the operator can use the telescopic rod 1 to extend the cleaning member 4 with the combustion member 411 to a position close to the wire. The combustion member 411 can remove these light and small materials by heating or burning. It should be noted that when using the combustion member 411, safety must be ensured to avoid causing a fire or damaging the wire. In spring, there are a large number of catkins flying near the high-voltage wire, and some catkins adhere to the wire. At this time, using this telescopic insulating rod with the combustion member 411, the combustion member 411 can be brought close to the catkins on the wire, and the heat generated by the combustion member 411 can be used to melt or burn the catkins, thereby cleaning the foreign objects on the wire. The design of the mounting fastener 410 enables the combustion member 411 to be conveniently mounted on the extension column 402 and can be adjusted and replaced as needed. This flexible mounting method improves the adaptability and practicality of the cleaning member 4. The combustion member 411 provides an effective method for cleaning light and small materials on the wire. For some foreign objects that are difficult to clean mechanically, the combustion member 411 can quickly remove them, improving the cleaning efficiency. When using the combustion member 411, the temperature and range of combustion need to be strictly controlled to ensure that the wire is not damaged. At the same time, the operator should take necessary safety measures to prevent the occurrence of a fire.

[0075] Embodiment 5

[0076] Referring to Figures 7 to 8 , which is the third embodiment of the present utility model. The difference between this embodiment and the third embodiment is that:

[0077] Compared with Embodiment 3, further, a cutting member 412 is further included. The cutting member 412 is arranged on the extension column 402, and the cutting member 412 is used to clean thick branches.

[0078] In this embodiment, when there are thick branches near the high-voltage wire that need to be cleared, the operator adjusts the length of the telescopic rod 1 to bring the cleaning member 4 with the cutting member 412 close to the branches. Using the sharp edge of the cutting member 412, the thick branches can be cut. When cutting, attention should be paid to controlling the force and angle to ensure that the branches are safely and effectively cleared while avoiding damage to the wire. In a high-voltage transmission line, if there are thick branches close to the wire, it may pose a threat to the safe operation of the wire. At this time, using this telescopic insulating rod with the cutting member 412, the cutting member 412 can be accurately aligned with the branches for cutting operation. The thick branches can be quickly cleared to ensure the normal operation of the high-voltage wire. The setting of the cutting member 412 provides an effective tool for clearing thick branches. Compared with other clearing methods, cutting can separate the branches from the wire more quickly, improving work efficiency. The installation fastener 410 enables the cutting member 412 to be firmly installed on the cleaning member 4 and will not loosen or fall off easily during use, ensuring the safety and stability of the operation. When performing the cutting operation, the operator needs to have certain skills and experience to ensure the accuracy and safety of the cutting. At the same time, attention should be paid to protecting the wire to avoid accidental damage to the wire by the cutting member 412.

[0079] Further, the telescopic rod 1 includes a support tube 101 which is an insulating tube, there are several inner tubes 102 which are sequentially sleeved inside the support tube 101, the first connecting member 2 is arranged at the end of the innermost inner tube 102, an insulating rotating fixing member, the inner tubes 102 are mutually clamped through the insulating rotating fixing member, and the support tube 101 and the inner tubes 102 are connected through the insulating rotating fixing member.

[0080] In this embodiment, the telescopic rod 1 includes a support tube 101, several inner tubes 102, and an insulating rotation fixing member. The support tube 101 is an insulating tube, which plays a major role in support and insulation. Several inner tubes 102 are sequentially sleeved inside the support tube 101, and the first connecting member 2 is arranged at the end of the innermost inner tube 102. The inner tubes 102 are connected to each other and the support tube 101 is connected to the inner tubes 102 through the insulating rotation fixing member, so that the inner tubes 102 can be telescoped inside the support tube 101 and can be clamped and fixed to each other through the insulating rotation fixing member in the extended state. In practical applications, when it is necessary to use the telescopic insulating rod to clean foreign objects on high-voltage wires, according to the height and distance of the wires, the inner tube 102 is gradually pulled out from the support tube 101 until the appropriate length is reached. The insulating rotation fixing member can ensure that the inner tube 102 will not accidentally retract in the extended state, ensuring the stability of the operation. When the cleaning work is completed, the inner tube 102 can be sequentially retracted into the support tube 101 by releasing the clamping of the insulating rotation fixing member, which is convenient for carrying and storage. Near a high-voltage substation, it is necessary to clean foreign objects on high-voltage wires. The operator uses this telescopic insulating rod and accurately extends the cleaning member 4 to the foreign objects on the wire by adjusting the extended length of the inner tube 102 for cleaning. Due to the insulating performance of the telescopic rod 1, the safety of the operator during the operation can be ensured. The combined design of the support tube 101 and the inner tube 102 enables the telescopic rod 1 to adjust the length according to actual needs, adapts to the operation requirements of different heights and distances, and improves the versatility of the telescopic insulating rod. The use of the insulating tube ensures that the operator will not be in danger of electric shock when contacting the telescopic rod 1, improving the safety of the operation. Especially when operating near high-voltage wires, the insulating performance is particularly important. The setting of the insulating rotation fixing member enables the inner tube 102 to be firmly fixed in the extended state, preventing the inner tube 102 from sliding or retracting during the operation, ensuring the stability and reliability of the cleaning work. The structural design of this telescopic rod 1 is reasonable, easy to operate and carry. When not in use, the inner tube 102 can be retracted into the support tube 101 to reduce the occupied space and facilitate storage and transportation.

[0081] Furthermore, the insulating connecting member is made of rubber material.

[0082] In this embodiment, the insulating connector made of rubber has good insulating properties and elasticity. When the telescopic rod 1 is adjusted in terms of its length, the insulating connector can play a role in stable connection and insulation between different components. The softness of rubber can adapt to a certain degree of deformation, ensuring the tightness of the connection, and at the same time reducing friction and wear between components. In the maintenance operation of high-voltage wires, a telescopic insulating rod with such a rubber insulating connector is used. The rubber material can effectively isolate the current and prevent the operator from getting an electric shock. Even in a humid environment, the insulating properties of rubber can remain stable, ensuring the safe progress of the operation. The rubber material has excellent insulating properties and can reliably prevent current conduction, providing safety protection for the operator. In a high-voltage environment, this is particularly important and can avoid the occurrence of accidental electric shock accidents. The elasticity of rubber enables the insulating connector to better adapt to the telescopic movement of the telescopic rod 1, reducing stress concentration caused by rigid connection between components. This helps to extend the service life of the telescopic insulating rod. Rubber materials usually have a certain degree of wear resistance and corrosion resistance and can maintain good performance in different working environments. Even after long-term use, it is not easy to show damage or aging phenomena. The rubber insulating connector has a relatively low cost and is easy to process and install. This makes the manufacturing and maintenance of the telescopic insulating rod more economical and efficient.

[0083] Furthermore, the support tube 101 has a rubber wrapping layer.

[0084] In this embodiment, the support tube 101 serves as the main support part of the telescopic insulating rod, and the rubber wrapping layer outside it plays multiple roles. First of all, rubber has good insulation performance, which further enhances the insulation effect of the entire telescopic insulating rod and ensures the safety of operators in a high-voltage environment. When using the telescopic insulating rod to perform operations such as cleaning foreign objects on high-voltage wires, even if it accidentally comes into contact with the high-voltage wire, the rubber wrapping layer can effectively block the current. Secondly, the rubber wrapping layer can provide a certain anti-slip effect. During the operation, the operator holds the telescopic insulating rod, and the surface friction of the rubber is relatively large, which can prevent the rod from accidentally slipping and improve the stability and safety of the operation. In addition, rubber also has a certain buffering effect, which can reduce the impact and vibration suffered by the telescopic insulating rod during use and protect the internal structure and components. At the maintenance site of high-voltage transmission lines, workers use telescopic insulating rods with rubber wrapping layers for operations. Due to the insulation, anti-slip and buffering characteristics of the rubber wrapping layer, workers can operate more reassuringly, improve work efficiency and reduce safety risks at the same time. Enhance insulation performance. The rubber wrapping layer provides additional insulation protection for the telescopic insulating rod, greatly reducing the risk of electric shock and enabling operators to work more safely in a high-voltage environment. Improve anti-slip performance. The surface characteristics of the rubber make it more stable for operators to hold the telescopic insulating rod and less likely to slip. Especially in a wet or oily environment, the anti-slip effect is more obvious. Provide buffer protection. During use, the telescopic insulating rod may be subjected to various external forces of impact and vibration. The rubber wrapping layer can absorb part of the energy, reduce the damage to the internal structure and extend the service life of the telescopic insulating rod. Improve the operation feel. The rubber wrapping layer is usually relatively soft, more comfortable to hold by hand, reducing the fatigue of the operator and improving the comfort and efficiency of work.
