Summary
The insulation sleeve, the puncture blades, the waterproof rubber mat, and the torque screws are the main parts of the insulation puncture clamp. Using a socket wrench, tighten the torque nut on the clamp to join the cable branches of the insulating clamp. First, place the branch cable into the branch cap to identify the location of the main cable branch.The puncture blade's insulation gradually closes up while, at the same time, the metal conductor and cable insulation are punctured by the puncture blade's piercing as its curving sealing ring gradually sticks to them. The torque nut will automatically loosen when the metal body of the puncture insert and the gasket and dielectric grease are in effective contact. Concurrently, this indicates that the installation is finished and the contact points' electrical efficacy and tightness are superb.
