Background

The strain clamp is a hardware fitting used for fixing a lead to bear the tension of the lead and hanging the lead to a strain insulator-string group or a tower. Strain clamps can be broadly classified into two types according to their structure and installation conditions. The first type: the strain clamp bears the whole tension of the lead or the lightning conductor, the clamp gripping force is not less than 90 of the rated tension of the installed lead or the lightning conductor, but the strain clamp does not serve as an electric conductor. The wire clamp can be detached after the wire is installed and used additionally. The cable clamp comprises a bolt type strain clamp, a wedge type strain clamp and the like. The second type: the strain clamp can bear all the tensile force of the conducting wire or the lightning conductor and can also be used as a conductor. Therefore, once the wire clamp is installed, the wire clamp can not be disassembled any more, and the wire clamp is also called a dead wire clamp. Because of the electrical conductors, the installation of the wire clamps must be carefully performed in compliance with the regulations regarding installation procedures. The strain clamp is used for corner turning, connection and connection of terminals. The spiral aluminum clad steel wire has extremely strong strain strength and no concentrated stress, and plays a role in protecting and assisting vibration reduction of the optical cable. The strain clamp is used for fixing a lead wire or a lightning conductor on a strain insulator string of a nonlinear tower, plays an anchoring role and is also used for fixing a stay wire of a stay wire tower.
