<p>PURPOSE:To reduce the number of components and to reduce in size a device by integrally molding a plurality of bus conductors arranged in a tank sealed with insulation gas and a plurality of insulating bushings to be externally led with insulation resin. CONSTITUTION:A plurality (3 of three phases) of bus conductors 2 are arranged in a tank 11 sealed with insulation gas. Conductors 13a-13c of the parts to be led out of the tank from the tank 11 are passed through an insulating bushing 14 having a flange 14a integrally molded by aligning them in one row for three phases by insulating resin molding such as epoxy resin, etc., and led from above. The central S-phase bushing 14 and the conductor 13b are longer than the bushing 14 adjacent to both sides and the conductors 13a, 13c, and connected to external conductors 5. Thus, the number of components is reduced, and its size is reduced, thereby obtaining sufficient air insulating distance.</p> |
