Environment-friendly high-temperature-resistant shielding fireproof flexible cable

Abstract

The invention discloses an environment-friendly high-temperature-resistant shielding fireproof flexible cable which comprises a guide core, an electromagnetic shielding layer, a fireproof layer, a sheath, a motor, a conical block, a blade and a guide pipe. An insulating layer, a first anti-oxidation layer, an electromagnetic shielding layer, a second anti-oxidation layer, a filling layer, a heat-resistant layer, the fireproof layer, a fiber layer, a waterproof layer and the sheath are fixedly connected to the outer side of the guide core in sequence. The outer wall of the sheath is sleeved with a lantern ring, a fixing frame is fixedly connected to the top of the lantern ring, a motor is fixedly connected to the fixing frame, and an output shaft of the motor is movably connected to the fixing frame. The environment-friendly high-temperature-resistant shielding fireproof flexible cable has stronger high-temperature-resistant and flame-retardant properties, the spontaneous combustion risk of the cable can be effectively reduced, less smoke is generated in the combustion process of the cable, the cable is more environmentally friendly, the cable has stronger anti-interference and anti-oxidation capabilities, and meanwhile, the surface structure of the cable can be quickly disassembled.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an environment-friendly, high-temperature-resistant, shielded and fire-resistant flexible cable. Background technique [0002] The cable is a kind of current transmission equipment. Its main function is to transmit the current produced by the power station to the long-distance electrical equipment. The wire inside the cable is mainly composed of copper metal. The cable is mainly divided into two types: AC cable and DC cable. [0003] However, existing cables have the following problems: [0004] 1. The high temperature resistance and flame retardancy of the cable are poor. When it is baked by the external high temperature, the cable is easy to spontaneously ignite, which will cause a lot of damage to the cable line and increase the cost of line repair. At the same time, a large amount of smoke will be generated during the burning process of the cable , pollute t...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide an environment-friendly, high-temperature-resistant, shielded and fire-resistant flexible cable to solve the above-mentioned background technology. The existing cables have poor high-temperature resistance and flame-retardant performance. A large amount of damage to the line increases the cost of line repair. At the same time, a large amount of smoke will be generated during the burning of the cable, which will pollute the air environment. The anti-interference ability of the cable is poor, and the current transmission performance of the cable will be reduced in a strong electromagnetic interference environment. , and there is no anti-oxidation protection structure of the copper guide core inside the cable. After the cable is used for a long time, the guide core is easily oxidized, and the cable skin structure is difficult to disassemble quickly.
