  • Sulfur hexafluoride circuit breaker - Wikipedia

    At very low outdoor temperatures, unlike air, SF 6 gas can liquefy, reducing the ability of the circuit breaker to interrupt fault currents. Oil-filled breakers contain some volume of mineral oil. A minimum-oil breaker may contain on the order of hundreds of litres of oil at transmission voltages; a dead-tank bulk oil-filled circuit breaker may contain tens of thousands of litres of oil.

  • 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 Sulfr hexafluoride a health hazard? Pure sf6 gas 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 Sulfr hexafluoride 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 % (*).
