GAS-INSULATED SWITCHGEAR AND METHOD FOR MANUFACTURING SAME

摘要

A gas insulated switchgear includes a high-voltage conductor (5) installed inside a ground tank (1) filled with an insulation gas and the high-voltage conductor (5) is supported on an insulation spacer (2) and thereby fixed to the ground tank (1). The gas insulator switchgear is configured in such a manner that an insulation portion (3) of the insulation spacer (2) in contact with the insulation gas is covered with a cover film (3a) formed by hardening powder of any of thermoplastic resin, glass, cellulose, and polymer resin made of carbon and hydrogen having a particle size of 100 µm or less with epoxy resin.
