Description

Technical Field

[0001] The present application relates to the technical field of power line fixing, and in particular to an insulating tension clamp. Background Art

[0002] In power line hardware technology, tension clamps are used to fix conductors and withstand conductor tension. They are key components to ensure the stable operation of power lines. With the development of power systems, higher requirements are placed on the insulation performance and mechanical strength of tension clamps.

[0003] Traditional tension clamps are typically made of metal and secure conductors via bolts or crimping. However, metal tension clamps are susceptible to environmental corrosion over long periods of use, affecting their mechanical strength and insulation performance. Furthermore, traditional tension clamps typically rely on external insulating sleeves or layers for insulation protection, which are easily damaged and can pose safety risks.

[0004] Therefore, metal tension clamps are susceptible to corrosion, the insulation protection is not reliable enough, and the maintenance cost is high. At the same time, the installation and disassembly process of traditional tension clamps is relatively complicated, which is not conducive to high-altitude operations.

[0005] To this end, the present application proposes an insulating tension clamp. Utility Model Content

[0006] The present application proposes an insulating strain clamp to solve the problems raised in the above-mentioned background technology; by adopting a combination of high-strength non-conductive materials and insulating materials, the present application provides a strain clamp device with both strong clamping force and good insulation performance. The device can effectively prevent power failures caused by leakage or short circuit, and improve the safety and stability of the power transmission system. At the same time, through optimized design and the use of detachable insulating parts, the service life of the strain clamp is extended, the maintenance cost is reduced, and the practicality of the device is greatly improved.
