  • 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 insulating gas 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.

  • Introduction to Gas Insulated Substations / Switchgears (GIS)

    gaz sf6 is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the insulating gas will not condense into a liquid at the lowest temperatures the equipment experiences. insulating gas has two to three times the insulating ability of air at the same pressure. Sulfr hexafluoride is about 100 times better than air for interrupting arcs.
