SF6 Gas & Measurement Theory - MBW Calibration AG 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.
Engineering Tutorials: SF6 Gas Technology heat created by the arc breaks the SF6 molecules into fluorine and sulfur. Arc energy is absorbed and the arc is cooled. As current zero is approached, the heat energy subsides as more SF6 gas enters the system. At current zero, the high-pressure SF6 gas flows through the nozzle and extinguishes the arc. Compressing the SF6 gas requires ...
