Abstract
A gas-insulated switchgear includes a main circuit conductor forming a bus line, a tank having a tubular main body in which the main circuit conductor forming the bus line is provided at its center, and a grounding-switch tank that is a branch pipe connected to the main body, in which a movable contact forming a branch line that branches from the main circuit conductor forming the bus line is provided, where a tubular surface of the main body is spherical, and has an opening that allows the movable contact to pass therethrough.
