▎ 摘　　要

NOVELTY - The utility model claims a cable unit based on graphene copper wire, coaxial cable and parallel double-shaft cable, the cable unit comprises a lead unit, the lead unit comprises a conductive core and an electric insulating layer covering the conductive core, the conductive core is composed of at least one surface covered with a graphene layer of the metal wire. The cable unit of the utility model uses the metal wire covered with graphene layer as the conductive core, which can improve the conductivity of the conductive core. when using at high frequency, the metal wire is skin effect, the graphene layer improves the conductivity of the metal wire more obvious, can obviously reduce the energy loss in the signal transmission process, reduce the conductor heating, so as to improve the signal integrity, increase the signal transmission distance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a coaxial cable; (2) a parallel double-shaft cable.
