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 - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.

Electrical Insulation Magazine - Nov/Dec 2019 - IEEE DEIS most cases the functional requirements depend on the application. There are huge differences between the conditions in a transformer with large gaps, ac stress, and a uniform field to that of a power converter with small dimensions, non-uniform fields, and square wave voltages. In our culture there is increasingly more control and regulations.
