Problems solved by technology

At present, with the development of society and economy, the amount of wire and cable is increasing rapidly, and the quality requirements for cables are also constantly improving, such as cables used in industries, electric power and coal mines, etc. The requirements are very high. In some special fields, the requirements for cables are very high. However, due to the unreasonable structural design of the existing cables, in practical applications, some cables are not suitable for work in some harsh environments. The cable skin is damaged by use, which not only distorts the signal transmission, but also brings a lot of inconvenience to the maintenance personnel and causes great losses to the enterprise.

Abstract

The invention belongs to the field of cables, and discloses a non-poisonous fireproof moistureproof insulating cable. The cable is prepared in a manner that an insulating outer layer wraps a conductor, and the insulating outer layer is made of the following materials: aluminium hydroxide, graphite, silicon carbide, triphenyl phosphate, oleamide, magnesium hydroxide, glass fibers, borax, palygorskite, stearic acid, aluminium nitride, egg shells, triallyl cyanurate, polypropylene resin, EPDM, polyethylene, and hydrogenated butadiene-acrylonitrile rubber. The conductor is an aluminium alloy conductor or an aluminium copper alloy lead. The cable is better in fireproof, moistureproof and waterproof performances and mechanical performances.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a non-toxic, fire-resistant and moisture-proof insulated cable. Background technique [0002] The high temperature and moisture resistance of the cable is particularly important, which is the guarantee for the normal transportation of electricity. At present, with the development of society and economy, the amount of wire and cable is increasing rapidly, and the quality requirements for cables are also constantly improving, such as cables used in industries, electric power and coal mines, etc. The requirements are very high. In some special fields, the requirements for cables are very high. However, due to the unreasonable structural design of the existing cables, in practical applications, some cables are not suitable for work in some harsh environments. The cable skin is damaged by use, which not only distorts the signal transmission, but also brings a lot of inconvenience to the mainten...
