SF6 gas valves plants for substation maintenance

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.

  • SF6 Gas handling | Zero emissions and maximum gas re-use

    SF 6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability. Thus, it is used in enclosed medium and high voltage switchgear as an arc quenching and insulating gas due to its properties. Unfortunately, the same properties that make SF 6 an excellent insulating gas for GIE also make it a potent greenhouse gas.

  • SF6: The Truths and Myths of this Greenhouse Gas

    SF6 is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, SF6 is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. SF6 is the energy industry’s “dirty little secret”: FALSE. SF6 is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives SF6 is used in wind turbines: TRUE. SF6 is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to SF6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on SF6 at low-to-medium voltage levels in the future.
