Anti-distortion type special composite cable

Abstract

The invention relates to the technical field of special composite cables, and discloses an anti-distortion special composite cable, which comprises a flame-retardant sleeve, a built-in main cable is arranged in the axis direction of the flame-retardant sleeve, a main cable wrapping layer sleeves the built-in main cable, and a protection layer is annularly arranged on the surface of the main cable wrapping layer. Through the improvement of an anti-twisting sleeve mechanism, when a twisting process occurs, a built-in main cable penetrates through the axis of a first twisting ring and the axis of a second twisting ring, so that the built-in main cable is arranged between the first twisting ring and the second twisting ring, and the safety of the built-in main cable can be improved; the plurality of connecting ropes can ensure the tensile property of the cable, and the auxiliary cables are arranged in the first limiting sleeve and the built-in pipe between the first twisting ring and the second twisting ring in a penetrating manner, so that the work of laying multiple cables on one cable can be realized, and the installation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of special composite cables, in particular to a twist-proof special composite cable. Background technique [0002] As the application range of power cables becomes wider and wider, different usage environments have different requirements, such as high temperature resistance, low temperature resistance, oil resistance, tear resistance, flame retardancy, animal damage prevention, etc. Especially in the case of special use conditions and complex application environments, the demand for special cables is becoming more and more prominent, and higher requirements are put forward for the reliability and durability of cables. Common special cables include: fireproof cables, heating cables, environmental protection cables and so on. In the prior art, according to the requirements of special cables, new structures, new materials, and new processes are often used to prepare special cables suitable for the requirements...

AI Technical Summary

Problems solved by technology

With the development of technology, in the field of materials, traditional cable materials, such as polyethylene, polypropylene, polyvinyl chloride, silicone rubber, fluoroplastics, etc., have been difficult to meet the actual needs

[0003] During the use of the existing special composite cables, the internal cables are wrapped with a variety of composite materials, and their functionality will be greatly improved, but the twist resistance of the existing special composite cables is tight Relying on the performance of synthetic materials to achieve distortion will cause internal damage. In this way, the service life of special composite cables will be reduced, and multi-line laying under special working conditions will also require separate laying. Bridge the cables, which will also increase the cost
