摘要： A tank filled with an insulating gas accommodates insulator tubes incorporating vacuum-valve breakers for individual phases. One end of each insulator tube is fixed to the inside of the tank. Each vacuum-valve breaker is installed generally on a common longitudinal axis with the corresponding insulator tube so that a movable electrode rod is directed toward a fixed end of the insulator tube. The insulator tube has as an integral part a bus line fixing portion projecting in a direction intersecting the longitudinal axis of the insulator tube from the proximity of an end opposite to the fixed end, supporting a bus-side conductor in an insulated fashion.
