▎ 摘　　要

NOVELTY - Graphene grounding system comprises at least two core rods and a coating drill bit. The coating drill bits are sequentially provided with a first graphene layer from inside to the outside, a foamed anti-corrosion layer and a second graphene layer. The connecting end of the core rod and the coated drill bit is connected with a core rod joint, where the radius of the connection between the core rods is smaller than the radius between the cores. The core rod joints are provided with multiple convex edges. The plated drill bits is provided with clamping grooves. The convex edge is clamped in the clamping groove. USE - Graphene grounding system for use in a power facility i.e. power plant, of an electric vehicle. Can also be used for a hybrid electric vehicle (HEV). ADVANTAGE - The core rod is more reliable and stable under the continuous driving of the electric hammer, reaching the effect of reducing the damage rate, and effectively improving the mounting efficiency of the working staff and the service life of the grounding system. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the graphene grounding system. First core rod (1a) Second core rod (1b) Plating layer drill bit (2) Acrylic acid (3)
