What is a strain clamp?

A strain clamp is a type of mechanical device used in electrical and utility applications to secure and support overhead cables or conductors. It is designed to relieve strain and tension on the cables caused by various factors such as wind, temperature changes, or the weight of the cables themselves.

The primary function of a strain clamp is to grip and hold the cable securely while allowing some degree of movement to accommodate expansion, contraction, or slight shifting of the cable. This helps prevent damage to the cables and the supporting structures by absorbing and distributing the mechanical stress.

Strain clamps are typically made of durable materials such as aluminum, steel, or other corrosion-resistant alloys. They come in various shapes and sizes depending on the specific application and the size of the cables they are intended to secure. These clamps are commonly used in electrical power transmission lines, telecommunications, and other utility installations where overhead cables are employed.
