advantages of IR SF6 joints manual

Dec 01, 1988 · Integrated IR intensities of SF6 in the v3 and v4 region were also measured by Brodbeck et al. (45). Up to a density of about 0.25 amagat, there was a linear dependence of the integrated absorption with density. The intensities of all the fundamentals and binary combination bands in the infrared spectrum of SF6 were measured by Dunn et al. (46).

  • Myth About SF6 Gas In Electrical Equipment

    Where is 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 SF6 a health hazard? Pure SF6 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 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 SF6 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 % (*).
