(CN216528194-U) NOVELTY - The utility model model claims a signal wire, the signal wire comprises a conductive wire core and graphene copper layer, graphene copper layer is foil sheet and covering the conductive wire core. The outer surface of the conductive wire core is coated graphene copper layer to improve the conductivity of the whole signal wire, so as to effectively reduce the high frequency signal transmission impedance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method for signal conductor. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a signal wire of a signal conductor. 10Signal lead 11Section diameter 100Conductive wire core 200Graphene copper layer 201Thickness
