Flame-retardant cable

Abstract

The invention discloses a flame-retardant cable. The middle part of a cable body is provided with a reinforcer, cable wires are arranged outside the reinforcer, the middle part of each cable wire is provided with a conductor, a conductor shielding layer is arranged outside the conductor, a fire-resistant layer is arranged outside the conductor shielding layer, an insulating layer is arranged outside the fire-resistant layer, an insulation shielding layer is arranged outside the insulating layer, and a flame-retardant layer is arranged outside the insulation shielding layer. A bushing is arranged outside the flame-retardant layer, a filling material is arranged outside the cable wires, a wrapping layer is arranged outside the filling material, an inner sheath is arranged outside the wrapping layer, a protective net is arranged outside the inner sheath, an outer sheath is arranged outside the protective net, and one end of the cable body is provided with a wiring terminal. According to the invention, the fire-resistant layer and the insulating layer cooperates with each other for use, the fire-resistant layer is a member made of a mica material, and has good insulativity and high-temperature resistance, by means of the mutual cooperation of the fire-resistant layer and the insulating layer, the use safety of the cable body can be further improved conveniently.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to flame-retardant cables. Background technique [0002] After several years of use of electric vehicles, the electrical components are likely to cause poor contact of the terminals under the continuous impact of large currents, which will cause severe heating of the cables. Most of the wire sheaths currently used do not have flame retardant effects. It is very easy to spontaneously ignite under the environment, leading to burning the car. While reducing the service life of the electric car and increasing its use cost, it may also cause safety accidents. [0003] Therefore, it is necessary to design flame-retardant cables to solve such problems. Contents of the invention [0004] The object of the present invention is to provide a flame-retardant cable to solve the problems raised in the background art above. [0005] In order to achieve the above purpose, the present invention p...
