SF6 room Grid Solutions for extra high Voltages

News Room : GE Grid Solutions Deployment of the g3 gas mixture as a replacement for SF6 has taken a major step forward: the F35-145 kV gas-insulated substation (GIS) is now SF6-free too. It has the same physical footprint as its SF6-based GIS predecessor and can operate at ambient temperatures as low as -25 C.
