Hard-toughened cable

Abstract

A tough cable is disclosed, include a first cable, the first cable is internally provided with a conductor, the outer side of the conductor is provided with a filling layer and the conductor and the filling layer are fixed by embedding, the outer side of the filling layer is provided with an outer sheath, a conductor is arranged inside the conductor, the outer side of the conductor is provided with an isolation layer and the conductor and the isolation layer are fixed by embedding, An insulating layer is arranged on the outer side of the insulating layer and is fixed with the insulating layerby embedding, an outer shielding cladding layer is arranged on the outer side of the insulating layer, A woven shielding layer is arranged on the outer side of the outer shielding cladding layer, Theinner conductor is effectively protected, and the tensile and pressure-resistant polymer material added into the outer sheath of the cable effectively increases the toughness of the cable, so that thecable is more durable, and only the clamp structure on the outer side of the cable is used when fixation is required between the cables, which is very convenient.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a tough cable. Background technique [0002] The cable is mainly composed of the following 4 parts. ① Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be formed by twisting a single wire or multiple wires. ②Insulation layer: The insulation material used for cables should have high insulation resistance, high breakdown electric field strength, low dielectric loss and low dielectric constant. Commonly used insulating materials in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, rubber, etc. Cables are often classified by insulating materials, such as oil-impregnated paper insulated cables, PVC cables, XLPE cables, etc. ③ Sealing sheath: protect the insulated wire core from mechanical, moisture, moistur...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of tough cable, to solve the above-mentioned background technology that the wires inside the existing cable squeeze each other, and the heat generated inside the wires transfers to each other, which easily causes damage to the inner wires, and is affected by the external protection of the cable. Due to the limitation of the sheath material, the cable is easily squeezed by other cables during transportation and pulled by human beings, causing the cable to be deformed or damaged, and other external auxiliary fixing devices are required when the cable is fixed, which is very cumbersome.
