Sulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive gas mixture. SF6 easily hydrolyses into fluorinated compounds in water (thionyl fluoride and hydrogen fluoride) that are extremely toxic and corrosive substances. And it is part of the six gases responsible of greenhouse effects covered by the Kyoto Protocol (one kilogram exhausted in the air equals around 23,000 kg of carbon dioxide (CO2) on the long run).

Get PriceThe SF6 transmitter is ideally suited for the gas measurement of sulfur hexafluoride in the field of high voltage engineering. The transmitter can be used both as a gas leak detector and to monitor the gas quality in gas-insulated switchgear (GIS) or transformers.
Get PriceNov 06, 2020When the gas pressure reaches 0.5 MPa, then PDIV value of SF 6 gas filled samples lie in the range of 25–30 kV, whereas pure N 2 gas sample shows below 25 kV at similar conditions. This may be due to the decrease in electron collision energy with increase in gas pressure which leads to the decrease in ionization process and ultimately results in improved resistance to streamer propagation [ 19 ].
