sf6 vacuum training for substation maintenance

Jun 22, 2014 · Instead of an objective selection based on real-world characteristics, the choice is very much driven by the circuit-breaker manufacturer. SF6 and vacuum switchgear enjoy varying market success in the different parts of the world (Figure 1) whereas Europe and most of the Middle East countries tend to favor SF6, China, Japan and the USA definitely prefer vacuum.
