The insulation piercing wire clamp is mainly composed of a reinforced shell, piercing blades, sealing gaskets, waterproof silicone grease, high-strength bolts, torque nuts, and cable terminal caps. When the cable needs to be branched or connected, the cable branch wire terminal is inserted into the waterproof terminal cap. After determining the main line branch position, use a socket wrench to tighten the torque nut on the wire clamp. During the process, the contact blade will puncture the cable insulation layer and make contact with the conductor, The sealing gasket presses around the puncture position of the cable, causing silicone grease to overflow from the shell. When the torque reaches the set value, the nut torque mechanism falls off, and the main and branch lines are connected
