  • Myth About insulating gas Gas In Electrical Equipment

    Where is gaz sf6 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 sf 6 a health hazard? Pure sf 6 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 sf 6 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 sf 6 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 % (*).

    Sep 01, 2000 · Insulating gas mixtures containing SF 6 have been promoted to serve as replacements for pure SF 6 in order to reduce SF 6 atmospheric emission. It has been argued that some synergism may be achieved by choosing proper buffer gases in mixtures with SF 6 such that the buffer gases efficiently slow down electrons into an energy range where the electron attachment cross section for SF 6 is large.
