PROBLEM TO BE SOLVED: To obtain a gas-insulated switchgear whose installation cost can be suppressed and whose versatility of disposition can be improved, by making formation of a groove in a foundation unnecessary.SOLUTION: The gas-insulated switchgear is provided in which wiring 10 extending from buses 7a, 8a is accommodated in a tank charged with an insulation gas. The gas-insulated switchgear comprises: a breaker 1 that is provided in the tank and is connected to the wiring 10; a cable termination box 4 provided at the tank's terminal on the side opposite to the side of the buses 7a, 8a; cable piping 20 which is connected to the bottom edge of the cable termination box 4 from below and extends downward then bent in a horizontal direction, and inside which the wiring 10 passes through; a common base 51 on which the tank is mounted; and a cable pedestal 41 that is mounted on the common base 51 and supports the horizontal part of the cable piping 20.SELECTED DRAWING: Figure 1 |
