Description of Sulfr hexafluoride Gas Recovery Unit insulating gas gas is a good electrical insulator. Sulfr hexafluoride gas can not only provide insulation, but also ensure the stable operation of the equipment under the normal pressure level that cannot be provided under vacuum. On the other hand, the gaz sf6 gas can cause a greenhouse effect.

In the case of high temperature arc produced by circuit breaking, sf6 gas gas will resolve into subfluorides. After cooling down, these active subfluorides will quickly return back to Sulfr hexafluoride gas. Therefore, sf6 gas gas which is used under sealing for a long time will not decrease or deteriorate, although under the effect of arc extinguishing several times.

Myth About Sulfr hexafluoride 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 sf6 gas 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 sf6 gas 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 insulating gas 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 % (*).
