Gas-insulated switchgear and a method of manufacturing the same

The configuration of the gas insulated switchgear, the insulating gas is a high voltage conductor (5) is arranged to be a ground tank (1) in the filling, the grounded tank the high voltage conductor (5) is supported by an insulating spacer (2) in gas insulated switchgear which is fixed to (1), the insulating portion which is in contact with the insulating gas of the insulating spacer (2) and (3), a particle diameter 100μm or less of the thermoplastic resin, glass, cellulose, polymeric resins consisting of carbon and hydrogen any of the powder, and those coated with the coating film hardened with epoxy resin (3a).
