SF6 Converter Station system

SF6 Converter Station system

Sulphur hexafluoride, SF 6, is a non-toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability. Due to its high dielectric strength, it is particularly suited for application in high power circuit breakers as well as in high-voltage cables, transformers, and switchgears.
