  • SF6 or Vacuum MV Circuit Breaker? - EEP

    Jun 22, 2014Instead 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.

  • SF6 Circuit Breaker: What Are They? (Types and Operation

    Oct 23, 2020An SF6 circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or SF 6 gas is used as the arc quinching medium, known as an SF6 circuit breaker. SF 6 gas has excellent insulating property and it has a high electronegativity. Due to high electronegativity, it has a high affinity for absorbing free electrons.

    However, the technology moved forward with the vacuum circuit breaker coming to dominate the medium voltage arena, and the gas circuit breaker (SF6) dominating for the higher voltages to the EHV range. These technologies exhibit a "constant kA" performance, which drove the ANSI/IEEE standards toward this ratings basis in the 1999 revisions.
