Get PriceAdvantages of sf6 gas System in Tanzania03/09/2018Sulphur hexafluoride (SF 6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF 6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and cooling medium.

22/03/2017A few remaining challenges that keep us from reporting the triple point of sulfur hexafluoride with an uncertainty comparable to the adiabatic cell result in are: 1) Unexplained melting curve shifts when extra (text {SF}_6) is added to the SS cell or when the vacuum jacket is used and 2) large temperature fluctuations while on the melting plateau. To resolve those remaining challenges will be the subject of a future work.
