摘要： A vacuum insulating switch gear formed by integrally molding with epoxy resin of a vacuum double-break three-position type switch including a movable contact, a fixed contact, and a vacuum container composed of an insulating cylinder for covering the movable contact and the fixed contact, a lower lid for closing a lower part of the insulating cylinder, and an upper lid for closing an upper part of the insulating cylinder and an operation rod side of the movable contact, and an earthing switch with a vacuum closed container, comprising a first silicone rubber layer coated on an upper edge corner portion of each insulating cylinder composing the vacuum containers of the switch and the earthing switch, a self fusing insulating tape layer wound around an outer surface of the first silicone rubber layer, a second silicone rubber layer coated on the self fusing insulating tape layer and an outer periphery of the each insulating cylinder, a ring easing shield installed at a position corresponding to a lower end corner portion of the each insulating cylinder after a vacuum deaeration process performed for the first and the second silicone rubber layers, and an epoxy resin portion for integrally molding the each vacuum container so as to cover the first silicone rubber layer, the self fusing insulating tape layer, the second silicone rubber layer, and the ring easing shield.
