▎ 摘　　要

NOVELTY - The cable has a round-shaped copper conductor (5) concentrically coated with a graphene-containing layer (4) and a rubber insulating layer (3). An outer ring is covered with a sheath (1). The copper conductor is provided with a filling layer (2). USE - Graphene containing rubber insulated cable. ADVANTAGE - The cable utilizes the graphene coating on a copper conductor surface, so that conductivity and quality of the cable body are improved. The cable has better mechanical performance, heat resistance and better chemical stability. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a graphene containing rubber insulated cable.
