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 conductors and lightning protection wires. These critical components are designed to withstand significant tensile forces, ensuring the stable suspension of wires onto tension strings or towers in power and communication networks.
Depending on the operational requirements, our tension clamps are categorized into two primary types: non-conductive structural clamps (including bolt and wedge types) and dead-wire clamps that serve as both anchors and electrical conductors. From high-tension power lines to specialized ADSS optical cable installations, these clamps provide the essential stability needed for corner, splice, and terminal connections.

Frequently Asked Questions
Q: What is the difference between a tension clamp and a dead-end clamp?
A tension clamp generally refers to the fixture securing the wire. A dead-end clamp specifically refers to the type that, in addition to bearing tension, also serves as an electrical conductor and cannot be disassembled once installed.
Q: Can these clamps be used for fiber optic cables?
Yes, we provide specialized tension fittings for ADSS optical cables with spans up to 100 meters, featuring grip strength of no less than 95% of the cable's rated tensile strength.
Q: What materials are used to ensure high tensile strength?
We utilize high-grade aluminum alloys and spiral aluminum clad steel wire to ensure maximum strength without creating concentrated stress points on the conductor.
Q: How do I choose between bolt type and wedge type tension clamps?
The choice depends on your installation conditions and whether you need the clamp to be removable. Wedge types often offer faster installation, while bolt types provide traditional heavy-duty security.
Q: Where are tension clamps typically installed?
They are used at corner towers, splice points, and terminal connections where the wire must be anchored to tension insulator strings of non-linear towers.
Q: Do these clamps help in reducing cable vibration?
Yes, specifically our designs using aluminum clad steel wire play a protective role in vibration reduction, which is crucial for the longevity of optical cables.
