NOVELTY - The utility model model claims a novel copper wire structure, comprising a sheath, the inner part of the sheath is provided with a mandrel, the outer part of the mandrel is provided with a copper core, the surface core is coated with a first layer graphene coating, the copper core is wrapped around the outer part of the mandrel, the outside of the copper core is provided with a second layer graphene coating, the outside of the second layer graphene coating is provided with an insulating layer, the insulating layer is integrally formed in the inner surface of the sheath. The novel copper wire structure is provided with graphene coating layer outside the single copper core wire and the copper core wire group, on the one hand, it can improve the conductivity on the other hand with good electromagnetic shielding performance.
