▎ 摘　　要

NOVELTY - The pulley has wheels symmetrically arranged on two sides of a main frame body (3). The wheels on each side are axially fixed on two sides of a protection plate (4). A middle side of the protection plate is provided with a conductive wheel group (5) transversely placed between two groups of wheels. An end of the conductive wheel group is connected to a grounding wire. The grounding wire includes an external insulating wire sheath and a composite wire core placed in the insulating wire sheath. The composite wire core is made of graphene wires and copper wires that are interlaced with each other. An inclined pull beam (31) and a supporting rod (32) are arranged on the main frame body. USE - Graphene copper transmission line pay-off grounding pulley for use in tension stringing construction. ADVANTAGE - The pulley can stably and efficiently release work, and can be folded and contained in transportation and storage process, and realizes grounding and guiding of induction power, thus preventing occurrence of arc situation, and improving usability and safety. The pulley has prolonged service life in high altitude operation. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene copper transmission line pay-off grounding pulley. 1Wire rope wheel 2Wire wheel 3Main frame body 4Protection plate 5Conductive wheel group 31Inclined pull beam 32Supporting rod 33Fixing lug 34Limiting pin 35Locking block 310Main rod 311Triangular plate 312Hanging hole
