Tension clamps are used for cornering, splicing, and terminal connections. Spiral aluminum clad steel wire has strong tensile strength.

Tension clamp
There is no concentrated stress, which protects the cable and assists in damping. The complete set of optical cable tensile members include: tensile pre-twisted wire and matching connecting fittings. The grip strength of the clamp is not less than 95% of the rated tensile strength of the cable. It is convenient and quick to install, reducing the construction cost. Applicable to ADSS cable lines with a pitch of ≤100 meters and a line angle of<25°.
The tension clamp is used to fix the wire or the lightning protection wire to the non-linear tower tower tensile insulator string, which acts as an anchor and is also used to fix the cable of the cable tower.
The tensile clamps can be roughly divided into two categories according to the structure and installation conditions. The first type: the tension clamp is to withstand the full tension of the wire or the lightning protection wire. The grip strength of the clamp is not less than 90 of the rated tensile strength of the installed wire or lightning protection wire, but not as a conductor. This type of clamp can be removed after the wire is installed and used separately. This type of wire clamp has a bolt type tensile clamp and a wedge type tensile clamp.
The second type: the tensile clamp is used as an electrical conductor in addition to the full tensile force of the wire or lightning conductor. Therefore, once such a clip is installed, it cannot be disassembled, and it is also called a dead clip. Since it is an electrical conductor, the installation of the clamp must be carried out in strict accordance with the provisions of the installation and operation procedures.
