  • 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) and more.

    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 SF6.
