sulfur hexafluoride Vacuum for Very High Voltages

Abstract. The electricity industry has been using sulphur hexafluoride (sf6 gas) for more than 40 years.sf 6 is an excellent insulating and arc-quenching medium and allows systems to be more powerful and more compact than any other available medium. As well as handling the highest voltages and make/break ratings, sf6 switchgear is also very
