Home / The main busbar of the high-voltage switchgear has a hole
In , a busbar (also bus bar) is a metallic strip or bar, typically housed inside, and for local high current power distribution, transmission, or switching substations. Laminated, or sandwich, busbars use thin conductors with insulation between layers. Busbar design within Medium Voltage (MV) switchgear is a critical aspect, fundamentally ensuring the safe, reliable, and efficient operation of power systems. It connects the incoming power to circuit breakers and outgoing circuits, helping power flow smoothly and evenly. The use of busbar for switchgear goes back to the dawn of electricity generation and is very common in both residential load centers of 200A and less and in industrial motor control center (MCC) applications of more than 1200A.
