  • SF6 gas in medium-voltage switchgear | TD Guardian

    It is also used in gas-insulated substations (GIS) and gas-insulated lines (GIL), highly suited to urban power transmission applications. In the medium-voltage realm (up to 38kV), SF6 has been used outside the United States for circuit breakers having relatively low interrupting ratings.

  • SF6 (GIS) gas insulated substation Manufacturer in China

    The SF6 gas insulated substation (GIS) is assembled by several SF6 gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of SF6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could operate in stable condition for
