NOVELTY - The method involves setting under protection of argon gas and hydrogen in growth temperature low on condition of 601 degrees C degrees centigrade to-1200 degrees centigrade for graphene of chemistry gas phase deposition, to obtain thickness of the graphene layer in 1 nano to 1 millimeter between the metal wire of graphene coated metal inner core of single wire forming. The graphene coated monofilament composite is set of the metal inner core forming composite cable structure. USE - Preparation method of graphene coated energy saving metal wire. ADVANTAGE - The graphene coated metal wire can effectively increase electric conduction capacity and greatly reduce transmission loss. The machine performance is increased and durability aspect wire performance is greatly increased.
