GE Vernova’s Gas-Insulated Lines (GIL) Dual Gas, available with SF₆ or SF₆-free with g3 gas, meet the challenges of electrical networks up to 800 kV.

GE Vernova’s Gas-Insulated Lines (GIL) Dual Gas, available with SF₆ or SF₆-free with g3 gas, meet the challenges of electrical networks up to 800 kV.
Ready for future SF₆ gas regulations
Anticipating future SF₆ regulations, from 2022 onwards, GE Vernova’s versatile 420-kV SF₆-GIL are fully g³-gas compatible. This dual gas equipment allows TSOs to easily switch from SF₆ to GE Vernova’s SF₆-free g³ solution in the future.
