Multifunctional cable

Abstract

The invention discloses a multifunctional cable which comprises a plurality of insulation wire cores, an inflaming retarding filling rope, an aluminum plastic composite belt isolation layer and an inflaming retarding sheath layer. The plurality of insulation wire cores are arranged on the periphery of the inflaming retarding filling rope, the aluminum plastic composite belt isolation layer wraps the outsides of the plurality of insulation wire cores, and the inflaming retarding sheath layer is arranged on the outer surface of the aluminum plastic composite belt isolation layer. By means of the combination structure of a fireproof insulation layer, the aluminum plastic composite belt isolation layer and the inflaming retarding sheath layer, the inflaming retarding fireproof performance of the cable is improved. Due to the fact that the plurality of insulation wire cores are arranged on the periphery of the inflaming filling rope and the inflaming retarding filling rope has flexibility, namely the inflaming retarding filling rope is easy to deform compared with the insulation wire cores, the inflaming retarding filling rope is pressed by the insulation wire cores when the cable is bent, and the outer edge of the inflaming retarding filling rope is deformed. Therefore, the cable has bending durability and flexibility and can be used under repeated bending environment, and environment adaptability of the cable is improved.

Description

technical field [0001] The invention relates to a cable, in particular to a multifunctional cable that can be used in fire and repeated bending environments. Background technique [0002] At present, the structure of most cables includes a conductor, a mica tape, an insulating layer, a filler, a wrapping layer and a sheath layer. In the gap of the core, the wrapping layer is wrapped on the outside of the cable core, and the sheath layer is wrapped on the outside of the wrapping layer, and the sheath material is mostly flame-retardant PVC material. [0003] During the use of the cable, especially in a fire environment, after a period of use, the insulated core of the cable is quickly destroyed, and the power is interrupted, which brings great hidden dangers to people's safety in using electricity; in addition, in robots or cars, etc. In an environment subject to repeated bending, the cables used not only require high bending durability, but also require high flexibility from...

[0003] During the use of the cable, especially in a fire environment, after a period of use, the insulated core of the cable is quickly destroyed, and the power is interrupted, which brings great hidden dangers to people's safety in using electricity; in addition, in robots or cars, etc. In an environment subject to repeated bending, the cables used not only require high bending durability, but also require high flexibility from the viewpoint of easy wiring. Existing cables cannot achieve both high bending durability and high flexibility

Thereby reducing the environmental adaptability of the cable
