▎ 摘　　要

NOVELTY - The material has a heat dissipation layer (1) formed with multiple wire holes. A line hole is connected with a graphene fiber conductive piece (2). The heat dissipation layer is provided with a reinforcing wire ring (3). The reinforcing wire ring is provided with a reinforcing wire (4). The reinforcing wire is connected with an insulating layer (6). The insulating layer is connected with a fireproof layer (5), where the reinforcing wire ring and the reinforcing wire are made of tungsten alloy material. The heat dissipation layer is provided with a graphene heat dissipation film. USE - Lead based graphene nano material. ADVANTAGE - The material effectively resist the wind rain hail and severe weather damage to the lead, and improves toughness and strength of the lead and radiating ability of the lead, and prolongs lifetime of graphene fiber conductive piece, and ensures uniform loss of heat by the graphene fiber conductive piece. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a lead based graphene nano material.
