Problems solved by technology

Due to the single flame retardant material, the cable will not only produce a lot of smoke and toxic gas during use, but also reduce the performance of the cable due to dehydration reaction, thus affecting the flame retardant temperature and flame retardant time of the cable, and it is difficult to achieve the effect of fire prevention and moisture resistance

Abstract

The invention discloses an aluminum oxide mineral isolated type fire-proof cable. The cable comprises a plurality of insulated cable core groups, a shield layer, an enhancement layer, a high-temperature-resistant layer and a protective layer; wherein each insulated cable core group is formed by twisting a plurality of insulated cable cores, each insulated cable core is composed of a conductor anda high-temperature insulating layer, and the outer sides of the conductors are wrapped with the high-temperature insulating layers respectively. The shield layer is wrapped on the peripheries of the insulated cable core groups, the outer surface of the shield layer is wrapped with the enhancement layer, the high-temperature-resistant layer is arranged on the outer surface of the enhancement layer,and the outer surface of the high-temperature-resistant layer is wrapped with the protective layer. The portion between any two insulated cable core groups is filled with an aluminum oxide mineral mixture, and the high-temperature insulating layer is an ethylene-tetrafluoroethylene copolymer layer. According to the cable, the cable is filled with aluminum oxide minerals, and the aluminum oxide minerals contain aluminum oxide and silicon dioxide so that the high-temperature resistance of the cable can be greatly improved.

Description

technical field [0001] The invention relates to the field of cables. More specifically, the present invention relates to an alumina mineral isolated fireproof cable and a preparation method thereof. Background technique [0002] At present, people's need for fast transmission of data and information, and their dependence on computers, word processors, teletype sensors and communication equipment have increased significantly and rapidly. The emergence of new technologies has made it possible to connect and network equipment in this area, leading to the comprehensive development of communication systems. The use of these systems has increased in specific areas such as high-rise buildings, ships, aircraft, trains, drilling platforms and mines. The insulating layer and the sheath layer of the existing flame-retardant cables are generally made by mixing a single flame retardant with the cable material. Due to the single flame retardant material, the cable will not only produce...
