3M™ Novec™ Insulating Gases

  • Cylinder for SF6-free, environmentally sustainable 3M™ Novec™ Insulating Gas

    3M™ Novec™ Insulating Gases

    • 3M Novec Insulating Gases combine excellent dielectric performance and safety with desirable environmental properties. When used as a component of advanced insulating and arc-quenching gases in the electric power industry, they provide the potential to significantly reduce environmental impacts associated with SF₆. These versatile gases enable a wide operating temperature window and are suitable for both medium- and high-voltage applications.
    • Benefits include:
       
      • Non-flammable
      • Zero ozone depletion potential (ODP)
      • Low global warming potential (GWP)
      • A wide margin of worker safety
    • Learn about insulating gas applications for the electric power industry

  • ABB AirPlus™ SafeRing™ equipment using SF6-free 3M™ Novec™ Insulating Gas for power utilities
    Reliable SF₆ alternative

    Pure Novec Insulating Gases offer higher dielectric strength than SF₆. In application, Novec insulating gases are typically mixed with inert gases where the mixture offers comparable dielectric strength to SF₆ and has a wide operating temperature window. The gas mixtures can be utilized in gas-insulated switchgear, circuit breakers and gas-insulated lines (GIL).

  • Electricity pylons in green field with power plant at the horizon
    Low global warming potential (GWP)

    SF₆, used in gas-insulated power equipment and lines, has a global warming potential 23,500 times that of CO₂ when compared over a 100-year period. Tests utilizing a gas mixture with Novec insulating gases demonstrate greenhouse gas reductions of more than 99% in on-grid commercial equipment versus equipment utilizing SF~6~.
