The wire clamp is mainly used for connecting a bus down lead of a substation with a wire outlet terminal of electrical equipment (such as a transformer, a circuit breaker, an isolation switch, a wall bushing and the like), and is divided into two series of aluminum equipment wire clamp and copper-aluminum transition equipment wire clamp in material because the wire outlet terminal of the common electrical equipment is copper and aluminum, and the bus lead wire is divided into steel-cored aluminum stranded wires of aluminum stranded wires. Strain clamps can be broadly classified into two types according to their structure and installation conditions. The first type: the strain clamp is required to bear the whole tensile force of the conducting wire or the lightning conductor, the clamp holding force is not less than 90 percent of the rated tensile force of the installed conducting wire or the lightning conductor, and the strain clamp is not used 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.
