Gas-insulated switchgear
A gas-insulated switch gear has a plurality of bay units having bus ducts each containing a three-phase bus and connected by bellows expansion joints. When the bay unit needs to be inspected for maintenance, the bellows expansion joints are compressed, and only the bay unit can be pulled out of the gas-insulated switchgear.
