SF6 Load Break Switch - 3b-energy.com3b-energy.com/download/12_MS SF6 Load Break Switch SQ.pdf· PDF fileSF6 is an inert gas and does not sustain combustion. The seal and the for-life lubrication of the rotary seals is provided by an oil film. In the MV circuit breaker field, for example, on more than 20000 SF6 switchgears units insatlled by the French electical utility (EDF) the annual fault rate related to seal problems is less than 0.05%.
