The parallel clamp is used for connecting small and medium-sized aluminum conductors or ACSR conductors and the shielding wires of overhead line conductors at positions that do not bear tension and is also used for jumper connections of non-linear pole towers. Power contracting materials (fitting tools) are mainly used for power line engineering projects. The PG clamp is a contact fitting connecting wires in parallel to transmit electrical loads. It is widely used, such as jumper wires of non-linear pole towers, T wiring at non-load-bearing connections of power systems, branch lines, switches, transformers, and other electrical equipment. , Lightning conductors, grounding down leads, etc., can be completed using parallel ditch clamps
