Cable with high shielding property

Abstract

The invention discloses a cable with high shielding property. The cable comprises a cable body, the cable body is provided with cable inner cores in triangular distribution, insulating layers are arranged outside the cable inner cores respectively, first shielding layers are arranged outside the insulating layers respectively, a fastening layer is arranged on an integral body formed by the cable inner cores and the first shielding layers, a second shielding layer is arranged outside the fastening layer, an anti-explosion layer is arranged outside the second shielding layer, a fireproof layer is arranged outside the anti-explosion layer, a braided reinforcement layer is arranged outside the fireproof layer, and a wearing layer is arranged outside the braided reinforcement layer. The cable has the advantages that both the first and second shielding layers arranged in the cable body enhances a shielding effect; the anti-explosion layer is designed to enhance the toughness of the cable body, and explosion in the using process is avoided; the fireproof layer enhances the fireproof performance of the cable body; and the braided reinforcement layer and the wearing layer improve the intensity of the cable body.

Description

technical field [0001] The invention belongs to the technical field of power cables, in particular to a cable with high shielding performance. Background technique [0002] Usually cables are used in subway stations, computer control centers, high-rise buildings, hotels, radio and television stations, and important military facilities, as well as places where people are concentrated and air density is low. When ordinary cables are used, when a fire occurs in the cable, the fire will be fierce, the combustion will be rapid, and the smoke will cause great harm. Combustion produces a large amount of harmful gases such as carbon dioxide, carbon monoxide, and hydrogen chloride. Cables containing halogen and heavy metal chemical components can cause pollution hazards such as air, water quality, and soil, and seriously endanger human health. The tensile effect is not good, so it is of great practical significance to design a multi-shielded cable. Contents of the invention [00...

AI Technical Summary

Problems solved by technology

Combustion produces a large amount of harmful gases such as carbon dioxide, carbon monoxide, and hydrogen chloride. Cables containing halogen and heavy metal chemical components can cause pollution hazards such as air, water quality, and soil, and seriously endanger human health. The tensile effect is not good, so it is very meaningful to design a multi-shielded cable
