3M™ Novec™ Insulating Gas – Sustainable SF₆ alternative

EU Commission announces timeline for SF6 phase out in Medium and High Voltage Switchgear
The EU Commission (DG CLIMA) has issued an update proposal for the so-called F-gas regulation (EU Regulation 517/2014). The proposal includes a Placing on the Market Prohibition (POM) for Medium and High Voltage Switchgear containing Sulphur Hexafluoride (SF6). The phase out timelines are subdivided by voltage class and clearly show:

The clock for SF6 is ticking:
now is the time for Transmission and Distribution System Operators to start planning for an SF6-free future!

    In addition, a recent study conducted by the University of Antwerp concluded that the reported SF6 stock and emissions are significantly underestimated. The study also provides an estimate of CO2 eq savings for potential SF6 phase out scenarios using the example of a 145kV Gas Insulated Switchgear (GIS).

3M Novec Insulating Gases – smart, safe, sustainable

Novec Insulating Gases are the ideal SF6 alternative as they combine excellent dielectric performance and safety with exceptional environmental properties. Used as part of a gas mixture, Novec Insulating Gases reduce the greenhouse gas potential by more than 99% in on-grid commercial equipment.

Our partners are using Novec Insulating Gases as part of their SF6 free products in multiple medium- and high-voltage applications going back to first installations in 2015:

    GE’s g³™ using 3M™ Novec™ 4710 Insulating Gas

    g3, (pronounced "g" cubed) is GE's game-changing alternative to SF6 gas, developed for HV electrical transmission equipment and is using 3M Novec 4710.

    g3 products feature the same ratings and same dimensional footprint as the state-of-the-art SF6 ones, with a drastically reduced environmental impact.
