Product Overview

The Copper Braided Grounding Jumper Strap (GJ Series Flexible Bonding Strap / Earth Jumper) is a vital electrical safety fitting designed for equipotential bonding and ground continuity across metallic structures. Manufactured by YiHao Power, these flexible copper straps bypass insulated paint, corrosion gaps, and mechanical joints in cable trays, distribution cabinets, and transformer enclosures, ensuring a low-impedance ground path to safeguard against electrical fault currents and static buildup.
