Make a meaningful change for the future of our planet. Choose 3M™ Novec™ Insulating Gases as an alternative to sulfur hexafluoride (SF6), the potent greenhouse gas commonly used to insulate and protect medium- and high-voltage electric transmission and distribution infrastructure.
The electric grid is the conduit for our rapidly improving quality of life, and its reliability is critical with little margin for error. But while the electrical power industry makes people safe, comfortable and productive, if leaks or unintended releases of SF6 occur, this results in a significant greenhouse gas impact on the environment.
That’s why at 3M, our scientists have focused on the insulating gas needs of the electrical power industry, where SF6 is used. The results of this extensive development and testing are 3M Novec Insulating Gases, which are often used in a gas mixture to achieve comparable or improved levels of performance with a dramatically reduced environmental impact compared with that of SF6 gas. If you’re looking to create a greener electric grid, we can help.
The electrical power industry has no margin for error, so Novec-based insulating gas mixtures perform within stringent safety and reliability specifications.
Higher dielectric strength than SF6 and a wide operating temperature window.
An SF6-free gas that can be utilised in gas insulated switchgear, circuit breakers, gas insulated lines (GIL) and more.
Reduced administrative burden to report SF6 greenhouse gas emissions.
Novec Insulating Gases combine excellent dielectric performance and safety with exceptional environmental properties. Used as part of a gas mixture, Novec Insulating Gases are suitable for both medium- and high-voltage applications, and are non-flammable and non-ozone-depleting.
This product was specifically developed to be a sustainable alternative to SF6 when used in its pure form or as part of a gas mixture, providing excellent dielectric properties and a wide margin of safety.

The first SF6-free 420kV gas insulated line (GIL) solution was installed at Sellindge, England, in 2016, with an insulating gas mixture using 3M Novec 4710 Insulating Gas. The installation follows years of research and collaboration, and demonstrates the commitment of GE, National Grid and 3M to reduce greenhouse gas emissions associated with use of SF6 in high-voltage power transmission equipment.
The brand new gas insulated switchgear (GIS) with AirPlus™ is a revolutionary eco-efficient SF6 alternative for medium-voltage applications. With a GWP of less than 1, it is the world’s first medium-voltage GIS with a new gas molecule incorporating 3M’s Novec 5110 Insulating Gas. The result — maintaining compact switchgear dimensions and all GIS advantages.
