▎ 摘　　要

NOVELTY - The graphene core electrical conductor has a graphite core which is surrounded by a sheath. The graphene core is formed by compression of graphene particles. The graphene core electrical conductor is formed by a powder bushing method. The graphene particles are filled into a jacket made of jacket material. The sleeve is pulled to form a graphene core and sheath composite. The material of the sheath is a metal or a polymer. The metal is selected from aluminum, copper, silver, and gold. USE - Graphene core electrical conductor of cable and of electric power transmission line (all claimed). ADVANTAGE - The conductivity of the graphene core electrical conductor is improved. The transmission loss and the total mechanical load on the transmission line of the graphene core electrical conductor are reduced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of graphene core electrical conductor. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the preparation method of graphene core electrical conductor.
