Myth About sf6 gas 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 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 insulating 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 % (*).

Sulfur Hexafluoride sf6 gas - A-Gas

It is generally transported as a liquefied compressed gas. sf6 gas allows simplified design of high and medium voltage switchgears because of size and weight reduction, quiet and reliable handling and maintenance. The emission of one kilogram of sf 6 is in terms of share of the greenhouse effect is equal to 23.500 kg CO2 emissions.Get price

Health and environmental dangers of sf 6-filled switchgear
