Preparation method for fireproof high-temperature-resistant cable

Abstract

The invention belongs to the field of cables, and particularly relates to a fireproof high-temperature-resistant cable. The fireproof high-temperature-resistant cable comprises a conductor, wherein the conductor is sheathed with an insulating layer, a shielding layer, a middle quilt layer, a waterproof layer, a fireproof high-temperature-resistant layer and an outer sheath; the fireproof high-temperature-resistant layer comprises a compound layer, chlorinated paraffin, aluminum oxide and asbestos powder, wherein the aluminum oxide is positioned on the outer side of the compound layer; the asbestos powder is arranged between the compound layer and the aluminum oxide; and the chlorinated paraffin is evenly arranged on the outer surface of the aluminum oxide. The fireproof high-temperature-resistant cable is compounded by organic matters and inorganic matters. Due to good fire resistance of the fireproof high-temperature-resistant cable, the fireproof high-temperature-resistant cable canguarantee the insulating performance of the cable when the cable carries out spontaneous combustion and an external fire hazard happens.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to a preparation method of a fireproof and high temperature resistant cable. Background technique [0002] In today's society, electricity is used in all walks of life around the world, and the world's demand for electricity is also increasing year by year. Because of this, the number of fires caused by electricity is also increasing every year, especially in some public places, such as large shopping malls, hospitals, and stations. and other densely populated areas. On December 15, 2005, a major fire occurred shortly after the renovation of Liaoyuan Central Hospital in Jilin Province, killing 37 people and injuring 95. The direct cause of the accident was that the cables used in the power distribution room were not flame-retardant, and combustibles were ignited after a short-circuit fault occurred. [0003] Due to the use of ordinary wires and cables, once a fire occurs, the cab...

AI Technical Summary

Problems solved by technology

[0003] Due to the use of ordinary wires and cables, once a fire occurs, the cable will burn, or other cable failures will cause the normal operation of the equipment to stop operating, and at the same time, the smoke will billow, and the light transmittance will drop instantly. On the one hand, it will cause damage to the equipment. On the other hand, due to the thick smoke and the lack of power supply of the indicator lights, the indication function is lost, so that the trapped people cannot find the escape exit, which will cause the people to suffer from diseases caused by inhaling a large amount of smoke and dust, and in severe cases, they will die due to suffocation. Under such conditions, rescuers cannot determine the specific location of property and trapped persons, resulting in a delay in rescue, resulting in a large number of property losses and casualties
