Successful Projects of sf6 gas filled plant

Successful Projects of sf6 gas filled plant

The first milestones in SF6-free switching technology from Siemens were the successful deployment of vacuum interrupters in outdoor circuit breakers, which have been in use since 2010. 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.

  • Sf6 Gas Processing Equipments - Vacuum Plant Instruments

    Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. SF 6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.
