PURPOSE:To provide an insulated switching device in which assembling of an apparatus in a tank can be facilitated from many directions. CONSTITUTION:A first member 15 of substantially U-shaped section integrated with an upper surface plate 15a, and side face plates 15b, 15b is so assembled and welded to a second member 16 of substantially U-shaped section integrated with a bottom plate 16a, a front surface pate 16b and a rear surface plate 16c that the sections becoming a U-shaped section are perpendicularly crossed to form a tank for filling insulation gas by incorporating an apparatus therein. |
