What is SF6?

SF6 is an artificial gas whose properties make it a great dielectric. Specifically, it exceeds the dielectric property of air by 2.5 times, making it an excellent electrical insulator.

Where is it used?

Over the last few decades, it has been applied in a large number of assets in electricity transmission and distribution networks, for example as an insulator in switchgear, transformers or GIS (Gas Insulated Substation), among others.

Why should we reduce its use?

• This will allow us to use technology in a more universal and efficient manner, also improving the times required by specialised technicians.
• This initiative allows the intensification of the roll-out of wideband in rural and remote areas.
• The call, directed at the whole entrepreneurial ecosystem, will be open until September 30^th.

• They are launching a technological innovation challenge to find innovative solutions to continue to drive the evolution and modernisation of these infrastructures.
• The call is available for the whole ecosystem and will remain open until 19 April.

Red Eléctrica de España, operator and transporter of the electricity system, and Elewit, the Group's technology platform, are jointly launching a technological innovation challenge to find new designs for high-voltage power line towers (also known as pylons).

All projects carried out at Elewit have an ultimate goal: to improve people's daily lives; our future. And we do this through innovation. We currently face various challenges that must be solved through technology. One such challenge addresses the possibilities of integrating new algorithms and functions in automatic substation systems.
