Abstract: PURPOSE:To improve the cooling efficiency by eliminating a gas flow not contributing to cooling, and eliminate use of a lower end frame packing, by integrally uniting a flange-shaped part outer periphery of the lower end frame with an upper end of a lower tank by welding. CONSTITUTION:A lower tank 60b, which is independently constructed from an upper tank 6a, is welded and integrally united air-tightly circumferentially with a flange-shaped part 51 outer periphery of a lower end frame 5 at an upper end thereof. The upper tank 6a is mounted on the upper portion of a structure so welded through proper means. Accordingly, insulating gas is prevented from flowing through a space between the tank 6 and a coil outer cylinder 10, and is allowed to flow only through a passage 3 for cooling a coil 1 and an iron core 2. Thus, the insulating gas is prevented from leaking outside the cooling passage and hence no packing for the lower end frame 5 is required.
