• 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 sf 6-free too. It has the same physical footprint as its insulating gas-based GIS predecessor and can operate at ambient temperatures as low as -25 °C.
