gis sf6 AIR EVACUATION wika climate impact

gis sf6 AIR EVACUATION wika climate impactThe compressed insulation used today can withstand very high temper atures and is tight fitting to minimize the potential for open spots where the hot gas can contact the outer walls of the ductwork. This is a great improve­ment over the mineral wool formerly used, which would break down and lose its insulating quality over time because of heat and turbulence.

sf6 gas leak working principle

sf6 gas leak working principle2017/8/243. 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. However in electrical switchgear the SF6 gas is always used in gas tight compartments, greatly minimising leakage.
