Tension Clamp，Strain Clamp，Dead-End Clamp

A tension clamp (strain clamp, dead end clamp) refers to a metal fixture used to secure wires, withstand wire tension, and hang wires onto tension strings or towers.

Tension clamps can be roughly divided into two categories based on their structure and installation conditions. Type 1: The tension clamp must withstand all the tensile forces of the conductor or lightning protection wire, and the clamping force of the clamp should not be less than 90% of the rated tensile force of the installed conductor or lightning protection wire, but it is not used as a conductor. This type of wire clamp can be removed and used separately after the installation of the wire. This type of clamp includes bolt type tension clamps and wedge type tension clamps. The second type: In addition to bearing all the tension of the conductor or lightning protection wire, the tension clamp also serves as a conductor. Therefore, once installed, this type of wire clamp cannot be disassembled, also known as a dead wire clamp.

Tension clamps are used for corner, splice, and terminal connections. Spiral aluminum clad steel wire has extremely strong tensile strength, no concentrated stress, and plays a protective and auxiliary role in vibration reduction for optical cables. The complete set of fiber optic cable tension fittings includes: tension pre twisted wire and matching connection fittings. The grip strength of the cable clamp is not less than 95% of the rated tensile strength of the optical cable, making installation convenient and fast, and reducing construction costs. Suitable for ADSS optical cable lines with a span of ≤ 100 meters and a line angle of<25 °

Tension clamps are used to secure wires or lightning rods to the tension insulator strings of non-linear towers, serving as anchors and also used to fix the tension wires of cable towers.
