gasbanor SF6 decomposition solution for gas-insulated switchgears

gasbanor SF6 decomposition solution for gas-insulated switchgears

helps reduce greenhouse gas emissions by utilising mixed gas-insulated technology together with vacuum switching technology. A 50% reduction in SF 6 is achieved by using Nitrogen ( N 2) in the SecoCube mixed gas-insulated breakers. Nitrogen is the largest component of air and its arc decomposition product is non-toxic.

  • 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 % (*).
