NOVELTY - The utility model claims a composite anti-corrosion cable, relating to the technical field of cable, the surface of the inner core is provided with a graphene layer, the outer part of the graphene layer is provided with an anti-corrosion layer, the surface of the anti-corrosion layer is provided with a plurality of uniformly distributed ring convex parts, the original insulating layer is changed into graphene layer, graphene has strong thermal conductivity and insulativity, at the same time of replacing the insulating layer, the heat generated by the inner core can be quickly transmitted to the filling layer, the temperature is prevented from being left on the inner core, at the same time, the ring convex part is set, the outer surface area of the outer skin layer is reinforced, so as to increase the contact area of the outer skin layer and the empty cavity, reinforcing the radiating effect of the cable, the outer layer material is made of polyurethane instead of ultraviolet resistance chloride, polyurethane with cold resistance (low temperature resistance), aging resistance, acid and alkali resistance, weather resistance, ultraviolet resistance that the cable is exposed to the outside for a long time will not aging, prolonging the service life of the cable.
