装置。[Claim for Utility Model Registration] In a gas-insulated switchgear in which conductors of three phases are housed in one tank, the shortest distance between the lowest conductor and the tank must be the same as that of the other two phases. The distance between the conductor and the tank should be greater than the shortest distance between the conductor and the tank, and the insulation distance between the conductor placed at the bottom and the other two phase conductors should be made larger than the shortest distance between the conductor placed at the bottom and the two phase conductors placed at the top. A gas insulated switchgear characterized in that the horizontal insulation distance between the conductors is equal to or greater than the horizontal insulation distance between the conductors.
