Novec Insulating Gases | 3M United Kingdom SF 6 alternative designed to reduce greenhouse gas impact by >99%. The electric industry has been willing to accept the challenges of using SF 6 as an insulating gas because of its dielectric properties and reliability. But SF 6 is a potent greenhouse gas with a global warming potential 23,500 times that of CO2 when compared over a 100-year period. In fact, it is the most potent greenhouse ...
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.
