sf6 switchgear applications FAQs about in Electrical Applications
The climax of my career was the application of the gas SF6 (sulfur hexafluoride) to high voltage switchgear, including the first 500 kw circuit breakers put into service in the United States. It all started with our attempts to answer customers' urgings to find a nonflammable substitute for oil in the design of high power circuit breakers.
