  • SF6 gas in medium-voltage switchgear | TD Guardian Articles

    SF6 has excellent dielectric properties, and is well suited for use in interrupting devices for relatively low switching ratings, such as for load interrupter switches used in the SIMOSEC switchgear line. Use of SF6 reduces the space requirements for the switchgear, isolates the switching elements from environmental contamination, and allows significant reduction of maintenance.
