▎ 摘　　要

NOVELTY - The grounding system has a grounding bar that comprises a grounding rod (1) and a rigid rod structure. The grounding rod is longitudinally buried deep in a soil layer and a grounding wire (2) which is laterally connected end to end above the ground rod. The surface of the ground rod is plated with a composite layer of graphene and zinc and silver. USE - Grounding system. ADVANTAGE - The silver layer improves the adhesion of the ground rod and the surface of the grounding wire, which promotes the bonding degree of the two metal layers of silver and zinc, improves the surface hardness of the grounding rod and the grounding wire. The grounding is struck during the construction process. The galvanized layer of the outermost layer of the grounding rod can be effectively prevented from peeling off, and the outer surface of the grounding wire is peeled off when the grounding wire is buried when the rod is used, so that the performance of the grounding system is more stable and reliable, and the applicable environment is wider. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the grounding system. (Drawing includes non-English language text) Ground rod (1) Grounding wire (2) Connector (4) Alloy drill bit (6)
