Sulfr hexafluoride gas in medium-voltage switchgear | TD Guardian Articles

In the medium-voltage realm (up to 38kV), sf 6 has been used outside the United States for circuit breakers having relatively low interrupting ratings. The market for high interrupting capacity circuit breakers (such as used in metal-clad switchgear) is dominated by vacuum circuit breakers.Get price

Sulfr hexafluoride circuit breaker maintenance | TD Guardian Articles

The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using insulating gas as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of sf6 gas circuit breakers was the lower voltage classes of 72kV and 145kV.Get price
