About this product
Product information from the supplier.
Tension clamps, also widely recognized as strain clamps or dead-end clamps, are critical high-strength metal fixtures engineered to secure electrical wires and lightning protection conductors. By effectively withstanding intense wire tension, these clamps ensure the stability of wires hanging onto tension strings or towers, providing essential structural integrity for power and communication networks.
Our professional range of tension clamps is categorized into two specialized types to meet diverse installation needs: removable mechanical clamps (Bolt and Wedge types) for versatile maintenance, and permanent dead-wire clamps that serve as both structural anchors and electrical conductors. Whether used for corner connections, splices, or terminal anchoring, our solutions guarantee maximum stability and safety in demanding environments.

Frequently Asked Questions
Q: What is the main difference between Type 1 and Type 2 tension clamps?
Type 1 clamps are purely mechanical fixtures used to withstand tensile force and can be removed after installation. Type 2 clamps, or dead-wire clamps, serve as both a tension anchor and an electrical conductor and cannot be disassembled once installed.
Q: Which tension clamp is best for ADSS optical cables?
Our fiber optic cable tension fittings are specifically designed for ADSS cables with spans ≤ 100 meters, providing grip strength of at least 95% of the rated tensile strength.
Q: How does aluminum clad steel improve performance?
Spiral aluminum clad steel provides extremely high tensile strength while eliminating concentrated stress, which is essential for protecting the core of optical cables.
Q: Where are these clamps typically installed in a power grid?
They are primarily used at corner towers, splice points, and terminal ends to secure wires to tension insulator strings and anchor them to cable towers.
Q: Can these clamps be used for lightning protection wires?
Yes, they are specifically engineered to withstand the tensile forces of both primary conductors and lightning protection wires.
Q: What are the common types of removable tension clamps?
The most common removable types are bolt-type tension clamps and wedge-type tension clamps, allowing for flexible installation and replacement.
