GE Vernova unveils world’s 1st 420 kV SF6-free g3 circuit-breaker for gas-insulated substations
- GE Vernova’s g³ 420 kV gas-insulated substation (GIS) circuit-breaker prototype demonstrates that g³ technology can be used at Europe’s highest voltage level, as well as other global voltage levels
- The use of g3 switching and insulation gas to replace SF6, a potent greenhouse gas, helps reduce the global warming potential (GWP) by more than 99%
- The LifeGRID project, co-funded by EU’s LIFE Programme, puts GE Vernova’s Grid Solutions at the forefront of the industry’s effort to create a clean
