According To The Installation Conditions, Tension Clamps Can Be Divided Into Several Categories

As we all know, Automatioc changover switch is used to fix the conductor or lightning conductor to the tension insulator string of the non-linear pole tower, acting as an anchor, and also used to fix the tension wire of the tension tower.

According to the different structures and installation conditions, tension clamps can be roughly divided into two categories.

First category: The tension clamp must bear the full tension of the conductor or lightning conductor, and the clamp gripping force is not less than 90% of the rated tensile strength of the installed conductor or lightning conductor, but it does not serve as a conductor. This type of clamp can also be removed after the conductor is installed and used separately. This type of clamp includes bolt-type tension clamps and wedge-type tension clamps.

Second category: In addition to bearing the full tension of the conductor or lightning conductor, the tension clamp also serves as a conductor. Therefore, once this type of clamp is installed, it can never be disassembled again, and it is also called a dead wire clamp. Because it is a conductor, the installation of the clamp must comply with the provisions of the relevant installation operating procedures and be carried out carefully.
