Metal Matters: Durability Secrets of Insulated Piercing Clamp

In high voltage power transmission networks, electrical connections use an insulated piercing clamp. It connects to the overhead wires that are already in place without de-energizing the line. Another name for an insulated piercing clamp is an insulated piercing connector (IPC). The sharp point of the clamp punctures the conductor’s insulation. This ensures a safe electrical connection without revealing the wire. By means of gripping mechanisms, it maintains its position even in the face of strong gusts. To prevent electric shock to the workers, the clamp also has insulated handles. The bolted IPC, compression IPC, tap connections and slicing connectors are the common types of insulated piercing clamps. They work in renewable energy systems, construction, and telecommunication.
