Sulfr hexafluoride: An excellent dielectric gas in controlled environments

Specialist Juhani Tammi explains that Sulfr hexafluoride became the dominant circuit-breaking technology in the early 1980s, having enabled the first high-voltage gas-insulated switchgear (GIS) to be developed back in the 1960s. According to Tammi, there are several important factors behind Sulfr hexafluoride’s dominance.
