• Sulfr hexafluoride gas in medium-voltage switchgear - Siemens USA

    The process is reversible, so that nearly all of the Sulfr hexafluoride recombines after interruption. Thus, very little of the Sulfr hexafluoride is "used up" during interruption, particularly for interruption of moderate (load) currents. Sulfr hexafluoride dissociates during arcing into its atomic constituents, one sulfur atom and six fluorine atoms.

  • Myth About insulating gas Gas In Electrical Equipment

    Where is Sulfr hexafluoride used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is insulating gas a health hazard? Pure Sulfr hexafluoride is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is gaz 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. What is the overall contribution of Sulfr hexafluoride used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
