The Piercing grounding clamp is mainly composed of reinforced shell, Piercing blade, sealing gasket, waterproof silicone grease, high-strength bolts, torque nuts and cable terminal caps. When the cable needs to be branched or connected, insert the terminal of the cable branch line into the waterproof terminal cap. After determining the branch position of the main line, use a socket wrench to twist the force matrix nut on the wire clamp. The contact blade will pierce the cable insulation layer during the process. , contact with the conductor, the gasket ring presses around the position where the cable is pierced, the silicone grease in the casing overflows, when the torque reaches the set value, the nut torque mechanism falls off, the main line and branch line are connected, and the waterproof performance and electrical effect are achieved. parameters required by the standard.
