SF 6 gas has been called the power grid’s dirty secret. This potent greenhouse gas is still commonly used in switchgear because it’s such an effective insulator. However, with a global warming potential 23,500 times higher than CO 2, SF 6 poses a huge challenge for the future. With viable alternatives now available, it’s time for power distribution networks to make the move towards more sustainable technologies like air insulated switchgear.
