    Abstract. The electricity industry has been using sulphur hexafluoride (SF 6) 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, SF 6 switchgear is also very compact and has been responsible for many resourcesaving developments, superseding both oil and air for arc-quenching and insulation 1.
