  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, Sulfr hexafluoride, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.
