SF6 Equipment Replacement station for substation maintenance

Jan 11, 2019 · Since the initial use of SF6 in the 1950s, SF6-containing circuit breakers, transformers, switches, fuses, and other equipment have been used regularly because SF6 is non-flammable, non-corrosive, non-toxic, and an effective arc suppressant, which allows SF6 equipment to have a small footprint and be relatively low maintenance.
