Fireproof wear-resistant copper core armored power cable

Abstract

The invention discloses a fireproof wear-resistant copper core armored power cable comprising a butadiene styrene rubber layer. An asbestos flame-retardant layer is fixedly connected on the internal surface of the butadiene styrene rubber layer. A fire-resistant fiber layer is fixedly connected on the internal surface of the asbestos flame-retardant layer. A self-locking steel tape armored layer is fixedly connected on the internal surface of the fire-resistant fiber layer. The self-locking steel tape armored layer is internally provided with a first insulating layer, a second insulating layer, a third insulating layer and a sheath. According to the fireproof wear-resistant copper core armored power cable, the source of fire can be preliminarily isolated for multiple times through the asbestos flame-retardant tape and the fire-resistant fiber layer so as to have great fire isolation effect; besides, the high temperature resistant pipe layer is arranged and the wire core can be protected so that the influence of high temperature on working of the cable can be avoided and the fire resistance of the cable can be enhanced; furthermore, the wear resistance, the heat resistance and the aging resistance of the cable can be enhanced through the butadiene styrene rubber layer, the tensile capacity and the shock resistance of the cable can be enhanced by the self-locking steel tape armored layer and the bending radius of the cable can be increased.

Description

technical field [0001] The invention relates to the technical field of electrical cables, in particular to a fireproof and wear-resistant copper core armored power cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] However, there are a lot of shortcomings in the existing power cables. For example, the performance of the existing power cables is poor in all aspects, and the fire resistance of the existing power cables is ...

Problems solved by technology

[0003] However, there are a lot of shortcomings in the existing power cables. For example, the performance of the existing power cables is poor in all aspects, and the fire resistance of the existing power cables is poor. When the power cables encounter an open flame, they will burn rapidly. , so that the cable is seriously damaged, and the power cable works for a long time, it will generate a lot of high temperature, these high temperatures are easy to cause damage between the protective layers inside the power cable, reducing the service life of the power cable, and now Some power cables have poor wear resistance and tensile energy
