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.
Switchgear Solutions - Power Line Magazine· Further, based on interrupting rating, a switchgear can be either circuit breakers, which can open and close on fault currents; or load-break/load-make switches that can switch normal system load currents; or isolators, which may only be operated while the circuit is dead or the load …
