Problems solved by technology

Some use flame retardants with halogen elements, but halogens will cause pollution. In addition, chlorinated polyethylene will release a large amount of toxic gases containing chlorine elements when it is burned, which is harmful to humans and the environment.
Therefore, this cable in the prior art does not have the characteristics of maintaining strong torsion resistance, not easy to crack, and stable work in an ultra-low temperature environment

Abstract

The invention discloses an ultra-low-temperature-resistant environment-friendly flexible cable, and relates to the technical field of cables. The technical scheme mainly includes that the ultra-low-temperature-resistant environment-friendly flexible cable comprises ultra-fine copper conductors, insulating layers and a protective layer, the insulating layers externally coat a plurality of strandedultra-fine copper conductors to form cable cores, the protective layer coats at least two cable cores, components of the insulating layers are as same as those of the protective layer, and the insulating layers and the protective layer comprise, by weight, 30-60 parts of polyvinyl chloride resin, 20-30 parts of ethylene propylene terpolymer, 15-30 parts of cold-resistant plasticizers, 20-35 partsof low-temperature-resistant modified materials, 10-15 parts of halogen-free flame retardants, 20-35 parts of fillers, 2-6 parts of antioxidant, 5-8 parts of stabilizers, 1-3 parts of lubricants and 2-4 parts of anti-aging agents. The ultra-low-temperature-resistant environment-friendly flexible cable solves the problem that an existing cable is low in torsion resistance and easy to crack in an ultra-low-temperature environment and can generate harmful gas in combustion. By the aid of the cold-resistant plasticizers and the low-temperature-resistant modified materials, the cable is high in torsion resistance and not easy to crack in the ultra-low-temperature environment and is environmentally friendly in combustion.
