  • gaz sf6 (GIS) gas insulated substation Manufacturer in China

    The gaz sf6 gas insulated substation (GIS) is assembled by several insulating gas gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of Sulfr hexafluoride 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

    A gas-insulated substation (GIS) uses a superior dielectric gas, insulating gas, 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 sf 6 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 insulating gas can do in centimeters.
