NOVELTY - The utility model claims a graphene-based self-heating cable, comprising a cable core, an insulating layer and a temperature control switch; the outer side of the cable core is orderly provided with the insulating layer from the inside to the outside, the heating layer, the outer protective layer, the outer protective layer is each provided with a group of said capacity ring at a certain distance; the immediate outer protective layer of the right side of the yield ring is fixedly connected with a group of said temperature control switch. by using graphite heating belt to heat, small volume, high heating efficiency, reduce energy waste and has good effect of preventing ice and snow gathering; by the outer protective layer is a steel wire woven protective structure, improves the strength of the cable. heating belt for good protection of the graphene, and better heat transfer efficiency, can more quickly melting snow, has good effect of preventing ice and snow gathering; the cable has simple structure, small volume, convenient production, simple installation and construction, and it is convenient to maintain.
