mbw sf6 insulated switchgear density sensor

mbw sf6 insulated switchgear density sensor

Dec 13, 2016For decades, the power transmission and distribution (TD) industry has been using sulfur hexafluoride (SF6) as the insulator in circuit breakers, disconnectors, and switchgear. The heat transfer and dielectric characteristics of this gas are better than those of air and other gases, so SF6 is a very effective arc quencher.
