  • SF6 (GIS) gas insulated substation Manufacturer in China

    The SF6 gas insulated substation (GIS) is assembled by several SF6 gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of SF6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could operate in stable condition for more than 30 years.

  • Gas-Insulated Substations - GIS - Electrical Engineering Portal

    A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, 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 SF6 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 SF6 can do in centimeters.
