In recent years, SF6/N2 gas mixtures especially with low SF6 mixing ratio was getting used as insulating medium in gas-insulated equipment for replacing pure SF6 which causes greenhouse effect. For the appliion of SF6/N2 gas mixtures in power equipment such as GIL, the breakdown characteristics of SF6/N2 gas mixtures in different electric field non-uniformity under lightning impulse were

elcome to the first ever printed gasworld directory, aiming to keep you at the forefront of the global industrial gases business. It seems appropriate to mention that in last month’s (March) issue of gasworld magazine we discussed mergers and acquisitions (M&A) and the changing face of the industrial gases industry, globally.
The commercial and environmental impliions are that N2/SF6 mixtures with 20% SF6 can achieve a ''significant'' dielectric withstand performance for a greatly reduced SF6 gas requirement (see also ''Guide for SF6 mixtures'', CIGRE Report 163, August 2000, by

DOT Cylinder Maintenance, Retest and Certifiion Requirements gives a stable reading of expansion and is accurate to ±1.0% of the total expansion of any cylinder tested or 0.1 cubic centimeter chlorodifluoromethane, chlorotetrafluoroethane, trifluorochloroethylene, or mixture thereof, or mixtures of one or more with
The properties of an industrial gas are one of the ways of deciding on the most suitable supply mode (along with other factors such as volume needs). For cylinder supplies, gases such as oxygen, nitrogen, argon, hydrogen and helium can be readily compressed
In particular, when focusing on SF6 gas, research on mixtures with N2 gas or with N2/SF6 gas mixtures which are a main constituent of the atmosphere and do not contribute to global warming are being widely implemented [2–6].
