A kind of high elastic composite cable

Abstract

The invention belongs to the technical field of composite cables, in particular to a high-elastic composite cable; the cable includes a core; the outer surface of the core is wrapped with a first protective layer, and the first protective layer is of elastic design; The outer surface of the first protective layer is wrapped with a first insulating layer, and the first insulating layer is designed in a wave shape; the outer surface of the first insulating layer is wrapped with a second insulating layer, and the second insulating layer is designed elastically; The outer surface of the second insulation layer is fixed with a uniformly arranged first tension layer; the present invention is mainly used to solve the problem that most of the structures in the existing cables are relatively single. Deformation will still occur under the rainwater erosion, which will cause the glue to break. At the same time, in the prior art, the cables made by some manufacturers cannot withstand overload operation. In addition, the elasticity of the cable itself is weak, which will cause the cable to expand. The problem of cracking which reduces the service life of the cable.

Description

technical field [0001] The invention belongs to the technical field of composite cables, in particular to a high-elasticity composite cable. Background technique [0002] With the rapid development of the national economy, the amount and scope of use of wire and cable are increasing. In recent years, industries such as power plants, substations, smelting and petrochemical industries have a great demand for control cables. In use, it is necessary not only to avoid mechanical damage, insulation damage, insulation aging and deterioration of the control cable, but also to use it under high temperature conditions, that is, high temperature resistance. Especially for control cables used in environments such as anti-corrosion and high temperature resistance, and need to be able to prevent discharge damage between cable cores and between cables, and have high mechanical properties such as high tensile strength, elongation at break, and High and low temperature resistance, bending ...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, the present invention proposes a high-elastic composite cable. The present invention is mainly used to solve the problem that most of the structures in the cables in the prior art are relatively single. Although the cable material itself has relatively high elasticity, the In the state of stretching for a long time, deformation will still occur after being eroded by rainwater, so that the glue will break and open. At the same time, in the prior art, the cables made by some manufacturers cannot withstand overload operation, and the elasticity of the cable itself Weaker which can cause the cable to expand and crack and reduce the service life of the cable
