Function of Copper Busbar in High Voltage Switchgear
Copper busbars offer excellent electrical conductivity and can carry high current with a smaller cross-section. The downside is higher cost and weight. In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution, transmission, or switching substations. These metal bars are connected together using welds or bolts, forming a complete conductive system. They connect the power source (such as the output terminal of a transformer) to various branches (such as the incoming terminals of circuit breakers), acting as a transfer station for electrical energy.
