The equipment clamp is mainly used for connecting the busbar down-conductor of the substation to the outlet terminals of electrical equipment (such as transformers, circuit breakers, isolation switches, wall bushings, etc.), because the outlet terminals of common electrical equipment are made of copper and aluminum. There are two types, and the busbar lead wire is divided into aluminum stranded wire or steel core aluminum stranded wire, so the equipment wire clip is divided into two series from the material: aluminum equipment wire clip and copper-aluminum transition equipment wire clip.
