SF6 circuit breaker maintenance - Siemens USA high pressure SF6 is released across the contacts by-way of a blast valve assembly, which is actuated during the mechanical operation of the breaker (either opening or closing). These dual pressure breakers were costly to build and costly to maintain.[email protected]

Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
