Sulfr hexafluoride Solutions – GTR

Circuit Breakers; VT’s; Precautions need to be taken Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas, and an excellent electrical insulator. [4] sf 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.

Sulfr hexafluoride Free Solution Switchgear Technology Options Conclusion

installations utilise Sulfur Hexaflouride (sf 6) as an insulator in both the switchgear bay and the circuit breaker. This results in higher volumes of insulating gas than an AIS solution. In this respect a solution fully utilising sf6 gas would not fully support the decarbonisation goals. gaz sf6 Free Solution
