NOVELTY - A graphene-containing interlayer is one insulation cable, comprising wire core and line core layer of composite sheath, a wire core comprising several single wire core unit, the single-core superconducting wires in core unit comprising one of copper core wire core unit and an annular covering a copper wire core unit outside layer of multiple aluminum wire core unit, copper wire core unit aluminum wire core unit and outer layer are covered with one layer insulation film, and the aluminum wire core unit of a insulation film and wire core set with one graphene layer; and a composite sheath including copper sheath and F-46 resin sheath layer outside of, and a F-46 resin sheath and copper sheath is set with one layer of graphene. Of a cable insulation resistance property and a pulse property in this utility new type relative b traditional insulation cable increase obviously, at the same time excellent weather resistance, high intensity, b fit outdoor electrical device use.
