sf6 vacuum solutions for railway

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 more than 30 years.
