About this product
Product information from the supplier.
Tension clamps, also known as strain clamps or dead-end clamps, are high-strength metal fixtures engineered to secure electrical conductors and lightning protection wires. These critical components are designed to withstand significant longitudinal tensile forces, ensuring that wires are safely anchored to tension strings or towers, thereby maintaining the structural integrity of power and communication networks.
Depending on the installation requirements, these clamps are categorized into two primary types: independent tension clamps (bolt or wedge type) which provide high-strength clamping without acting as a conductor, and dead-end clamps which simultaneously bear the full tension and serve as a conductive path. From traditional power lines to advanced ADSS optical cables, our tension fittings ensure maximum stability and vibration reduction.

Frequently Asked Questions
Q: What is the difference between a tension clamp and a dead-end clamp?
A tension clamp generally secures the wire to withstand tensile force; however, a dead-end clamp specifically serves as both a tension anchor and a conductor, meaning it cannot be disassembled once installed.
Q: How does the clamping force of these products compare to the wire's strength?
Our tension clamps are engineered so that the clamping force is no less than 90% of the rated tensile force of the installed conductor or lightning protection wire.
Q: Are these clamps suitable for fiber optic cables?
Yes, we provide specialized tension fittings for ADSS optical cables with grip strengths reaching at least 95% of the cable's rated tensile strength, suitable for spans up to 100 meters.
Q: What material is used for vibration reduction in these fittings?
We use spiral aluminum clad steel wire, which provides extremely strong tensile strength and prevents concentrated stress, effectively reducing vibration for optical cables.
Q: In which scenarios are tension clamps typically utilized?
They are essential for corner connections, splice points, terminal connections, and for fixing wires to the tension insulator strings of non-linear or cable towers.
Q: Can bolt-type tension clamps be reused?
Yes, Type 1 tension clamps (including bolt and wedge types) are designed so they can be removed and used separately after the wire installation is complete.
