Phase Segregated Type Sulfr hexafluoride Gas Insulated - Fuji Electric

Fuji started the development of SF 6gas insulated switchgear (GIS) in 1966. The first 72.5 kV GIS, which was of the phase segregated type, was put into operation in 1970. Since then Fuji also developed three phase encapsulated type GIS in addition to phase segregated one as our standard series of GIS.
