HighStrength Tension Clamp and DeadEnd Clamp China Factory Suppliers
A Tension Clamp, also widely known as a Strain Clamp or Dead-End Clamp, is a critical high-strength metal fixture engineered to secure overhead conductors and lightning protection wires. Designed to withstand significant longitudinal tensile forces, these clamps ensure the structural integrity of power and communication lines by anchoring wires securely to tension insulator strings or tower arms, preventing line sagging and failure.
Depending on the operational requirement, these clamps are categorized into two primary types: non-conductive tension clamps (Bolt or Wedge type) which focus purely on mechanical anchoring and can be removed after installation, and conductive dead-end clamps which serve as both a mechanical anchor and an electrical conductor. From standard power distribution to advanced ADSS optical cable deployments, our tension clamps provide the stability required for corners, splices, and terminal connections in challenging environments.

Frequently Asked Questions
A tension clamp generally focuses on securing the wire against tensile force. A dead-end clamp specifically serves as both a mechanical anchor and an electrical conductor, meaning it cannot be disassembled once installed to maintain the circuit.
For ADSS optical cables, we recommend specialized fiber optic tension fittings with spiral aluminum clad steel wire, ensuring a grip strength of at least 95% of the cable's rated tensile strength for spans up to 100m.
Wedge-type clamps utilize a self-tightening mechanism as tension increases, offering faster installation. Bolt-type clamps provide a manual, high-torque securement often preferred for specific high-load industrial applications.
Yes, tension clamps are specifically designed to secure both power conductors and lightning protection wires to the tension insulator strings of non-linear towers.
It provides extremely strong tensile strength without creating concentrated stress points, which is essential for reducing wind-induced vibrations and protecting the integrity of sensitive optical cables.
They are primarily used at corner towers, splice points, and terminal ends where the line must be anchored firmly to a tower or pole to maintain tension across the span.
