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.
High Voltage Gas Insulted Switchgear (GIS) Field Testing ...· The final assembly of the gas insulated substation is then completed in the field, where all the various components that comprise a GIS meet for the first time. Even if the gas insulated.substation could be completely assembled in one factory, it would still need to be disassembled for shipment, shipped, and then reassembled at the job site.
