Your Complete Drop Wire Clamp Guide

Drop wire clamp as used in overhead transmission lines

A drop wire clamp is a component used to support and secure individual wires or cables that drop or hang down from the main conductor. It is also known as a suspension clamp or wire suspension clamp. The clamp also manages the downward connections of service wires. These includes distribution lines that provide electricity to homes or businesses. They are from materials that are strong, durable and resistant to environmental factors. These include galvanized steel, aluminum or stainless steel. Common types of drop wire clamps include parallel groove clamp, bolt-type drop wire clamp, suspension drop wire clamp and messenger wire clamp. Drop wire clamps help to provide reliable support and seamless connectivity for secondary wires. They find use in various applications in the industry such as distribution lines, service connections, telecommunication lines, renewable energy and transmission lines.

Key features of drop wire clamp
