Environment-friendly fireproof cable

Abstract

The invention provides an environment-friendly fireproof cable, and the cable comprises an inner core; the inner core is formed by twisting multi-core cable cores, and an insulating layer, a shielding layer, a fire insulation layer and a fireproof layer are sequentially arranged outside each cable core from inside to outside. A waterproof layer, a heat insulation layer, an oxygen isolation layer, a flame retardant layer, an armor layer and an outer sheath are arranged outside the inner core from inside to outside, and a gap between the fireproof layer and the waterproof layer of each cable core is filled with a radiating tube, a filling rope and a galvanized steel wire. The heat dissipation pipe, the filling rope and the galvanized steel wire separate the cable cores provided with the insulating layer, the shielding layer, the fire insulation layer and the fireproof layer from each other to form independent cable cores. The oxygen isolation layer comprises a preset number of oxygen isolation pipes, and the oxygen isolation pipes are filled with carbon dioxide gas. The fire retardant layer and the fireproof layer form a double-layer fireproof structure, and the oxygen barrier layer and the flame-retardant layer form a double-layer flame-retardant structure, so that the flame-retardant and fireproof performance of the cable is greatly improved, and the use performance is high.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to an environment-friendly fireproof cable. Background technique [0002] With the rapid development of my country's social economy, the amount of cables is also increasing, and the number of fires in large public entertainment places, chemical industry, coal mines and commercial buildings has also increased, causing tragic losses to people's lives and property. At present, people have a very deep understanding of fire protection and fire safety. With the rapid growth of urban population and the increase of large public places such as high-rise buildings, hotels, supermarkets, hospitals and playgrounds, fire safety is particularly important. [0003] Most of the building fires are caused by electrical lines. Since the wires and cables are often laid in bundles, the heat radiation of the combustion is conducted to each other, causing the fire to spread continuously....

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an environment-friendly fireproof cable to solve the problem that the performance of the wire and cable is not kept for a long time under high temperature and fire conditions, and the combustion produces toxic gas, which affects the escape and rescue of personnel.
