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.

Electricity Transmission Costing Study though, to date, no converter of this size exists in the UK. This size of converter offers the cheapest way of providing an HVDC like-for-like comparison with the AC double circuits considered in this study, though we understand that larger converters have already been offered into the market.
