Composition And Use Of Insulation Piercing Clamp

Insulation Piercing Connector is mainly composed of an insulating shell, a puncture blade, a waterproof rubber pad, and a torque bolt. It is suitable for the connection of overhead low-voltage insulated cables, low-voltage insulated household T-connections, cable branches in building distribution systems, underground low-voltage insulated cable connections, streetlight systems, and grounding protection. The applicable voltage level is 10kV and below.

When connecting the cable branch, insert the branch cable into the branch cap and determine the main line branch position. Tighten the torque nut on the wire clamp with a socket wrench. As the torque nut is tightened, the upper and lower insulators of the wire clamp with hidden puncture blades gradually close together. At the same time, the arc-shaped sealing pad wrapped around the puncture blade gradually adheres to the cable insulation layer, and the puncture blade also begins to puncture the cable insulation layer and the metal conductor. When the sealing degree of the sealing pad and the insulating grease and the contact between the puncture blade and the metal body reach the best effect, the torque nut automatically falls off. At this time, the installation is completed and the contact point sealing and electrical effect are optimal.
