SM-35 BMC/SMC Standoff Composite Busbar Insulator

Busbar insulator is mainly used for low voltage power distribution cabinets, frequency converters, and other products.By connecting the busbar support copper, it plays a role in fixing, supporting and insulating. Busbar support insulator has excellent insulation performance, high strength, high temperature resistance, reliable safety performance, and is the excellent choice for fixed busbar of low-voltage power distribution cabinets.
