Abstract
In a three-phase integrated gas insulated bus, three vertical outlets are formed in the longitudinal direction of a cylindrical bus enclosure and three horizontal outlets are formed in almost the same axial position as these vertical outlets in the circumferential direction. The three-phase main bus conductors are laid out to ensure that one side of a triangle having the apexes where three-phase main bus conductors are located is approximately parallel to these horizontal outlets . The main bus conductors are extended to the three vertical outlets sequentially starting from the main bus of the phase closest to the vertical outlets , and branch buses and are led from the tip positions thereof to the vertical outlets and horizontal outlets
