Wedge Clamps

Wedge Clamps for Overhead Service Entrance Cable

Wedge clamps are specialized electrical connectors used to secure overhead service-entrance cables to a structure while relieving strain on the electrical service equipment. They are commonly used to anchor triplex service cables to a building before the cable enters the meter or service panel.

The clamp grips the messenger wire of the triplex cable and attaches to a mounting eye bolt, bracket, or anchor on the structure. This creates strain relief so the weight and tension of the overhead cable are supported by the clamp instead of the electrical equipment.

How Wedge Clamps Work

A wedge clamp consists of a body and an internal wedge insert. The messenger wire from the triplex cable is placed inside the clamp, and the wedge is driven into position. As tension is applied to the cable, the wedge tightens and locks the conductor in place, creating a secure mechanical hold that resists slipping.

This self-tightening design provides dependable performance in outdoor electrical installations and helps maintain a strong connection even with vibration, wind movement, or thermal expansion.
