News Room : GE Grid Solutions

Deployment of the g3 gas mixture as a replacement for sf 6 has taken a major step forward: the F35-145 kV gas-insulated substation (GIS) is now insulating gas-free too. It has the same physical footprint as its Sulfr hexafluoride-based GIS predecessor and can operate at ambient temperatures as low as -25 °C.

Gas-Insulated Substations - GIS

A gas-insulated substation (GIS) uses a superior dielectric gas, sf6 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 sf6 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 gaz sf6 can do in centimeters.
