  • SF6 gas in medium-voltage switchgear | TD Guardian

    SF6 is used in the SIMOSEC switchgear design for the load interrupting switch and for the switch-disconnector in a variety of configurations. This design takes advantage of the main characteristics of SF6 and minimizes the environmental issues associated with the gas. The switch is enclosed in a welded stainless-steel vessel of enclosure.
