About this product
Product information from the supplier.
Tension Clamps, also known as strain or dead-end clamps, are high-performance metal fixtures engineered to secure power and communication wires. These essential components are designed to withstand intense tensile forces, ensuring the stable suspension of conductors and lightning protection wires onto tension strings or towers, thereby maintaining the structural integrity of the entire power grid.
Depending on the operational requirements, these clamps are categorized into two primary types: structural support clamps that can be removed after installation, and conductive dead-end clamps that serve as both an anchor and a current conductor. From ADSS optical cables to high-voltage power lines, our tension clamps provide a reliable solution for corner, splice, and terminal connections, optimizing safety and network stability.

Frequently Asked Questions
Q: What is the primary difference between Type 1 and Type 2 tension clamps?
Type 1 clamps provide mechanical support and can be removed after installation. Type 2 clamps act as both a support and an electrical conductor and cannot be disassembled once installed.
Q: How does the grip strength of these clamps affect ADSS optical cables?
Our clamps maintain a grip strength of no less than 95% of the cable's rated tensile strength, which prevents cable deformation and ensures signal stability in communication lines.
Q: Where are tension clamps typically utilized in power distribution?
They are used primarily at corner towers, splicing points, and terminal ends of lines to anchor the wire securely to insulator strings.
Q: What material is used to ensure high tensile strength in these fittings?
Spiral aluminum clad steel is used to provide extreme tensile strength while ensuring there is no concentrated stress on the conductor.
Q: Are these clamps suitable for spans over 100 meters?
The standard fiber optic cable tension fittings mentioned are specifically designed for ADSS lines with a span of 100 meters or less.
Q: Can wedge type clamps be used for lightning protection wires?
Yes, both bolt-type and wedge-type tension clamps are suitable for securing conductors and lightning protection wires to tension towers.
