HighStrength Tension Clamp Strain DeadEnd Clamp China Factory Suppliers
A Tension Clamp, also known as a Strain Clamp or Dead-End Clamp, is a high-performance metal fixture engineered to secure power and communication wires. These critical components are designed to withstand immense wire tension and facilitate the stable hanging of conductors onto tension strings or towers, ensuring the structural integrity of the overall grid.
Our professional-grade tension clamps are versatile solutions used for corner, splice, and terminal connections. From bolt-type and wedge-type options to specialized fiber optic cable fittings featuring spiral aluminum clad steel wire, our products ensure maximum grip strength and vibration reduction for ADSS optical cables and lightning protection wires.

Frequently Asked Questions
Type 1 clamps focus solely on bearing tensile forces and can be removed after installation. Type 2 clamps (dead wire clamps) serve both as a tension anchor and an electrical conductor, meaning they cannot be disassembled once installed.
Our fiber optic cable tension fittings use spiral aluminum clad steel wire to reduce vibration and eliminate concentrated stress, maintaining a grip strength of at least 95% of the cable's rated tensile strength.
They are primarily used for corner connections, splice points, and terminal ends of power or communication lines where the wire must be permanently anchored to a tower.
For our specialized fiber optic cable tension sets, they are suitable for ADSS optical cable lines with a span of ≤ 100 meters.
Yes, tension clamps are specifically designed to secure both main conductors and lightning protection wires to tension insulator strings on towers.
Ensuring the clamping force is ≥ 90% (or 95% for optical cables) of the rated tensile force prevents cable slippage and ensures the stability of the line under extreme environmental weather conditions.
