<p>PURPOSE:To reduce the number of components, to enhance economy and to support a long conductor by shutting OFF fluid to be supported by liquid insulator solidified to the support, and forming a shut-off part for directly dropping to a bottom of a sealed vessel at the support. CONSTITUTION:An insulating support 4 has a runabout part 42A in which three supporting rods 42 extended from a supporting part 41 of a bus 3 to an inner wall of a sealed vessel 1 are once run about to the part 41 at the intermediate of the extension. The part 42A is formed as a shut-off part for shutting OFF fluid E composed of liquid insulator solidified on the surface of the support 4 without guiding directly to the inner wall of the vessel 1, and the insulator is dropped from the shut-off part directly to the bottom of the vessel 1 as denoted by D. Accordingly, even if vapor mistlike liquid insulator is solidified on the surface of the support 4, the solidified liquid droplet forms a fluid passage E to the part 42A, a passage leading to the inner wall of the vessel 1 is not formed, and an insulating breakdown strength can be improved.</p> |
