SF6 Breakers Grid Solutions for Ultra High Voltage

SF6 Breakers Grid Solutions for Ultra High Voltage

SF6-free GIS for 72.5 kV have been used in wind turbines and the first SF6-free outdoor circuit breaker in the German 110-kV high-voltage grid since 2018. The benefits of this technology over conventional SF6-insulated switchgear are significant: high switching power with the same footprint for outdoor and dead-tank circuit breakers.
