The equipment clamp is used to connect the descending wire of the busbar to the output terminals of electrical equipment (such as transformers, circuit breakers, transformers, disconnectors, wall bushings, etc.).
Nowadays, the output terminals of commonly used electrical equipment are made of copper and aluminum, and the output wires are mainly aluminum stranded wires or steel-core aluminum stranded wires. Therefore, equipment clamps are divided into two types: copper equipment clamps and copper-aluminum transition equipment clamps. series.
The pole end of the transformer wire clamp adopts the design principle of screw sleeve and side slot. After the wire clamp is installed on the conductive rod of the equipment, the screws on both sides of the slot are tightened, which has the advantages of large electrical contact area and close contact. The other side adopts pressure plate and flat plate respectively. , round tubes and other means of connection with busbars, wires and terminal blocks have a wide range of applications.
