SF₆ Gas-Insulated Lines
At 420 kV, SF₆ today – Ready for g³ gas tomorrow
Ready for future SF₆ gas regulations
Anticipating future SF₆ regulations, from 2022 onwards, GE’s versatile 420-kV SF₆-GIL are fully g³-gas compatible. This dual gas equipment allows TSOs to easily switch from SF₆ to GE’s SF₆-free g³ solution in the future. Main Characteristics
Environment friendliness
Reliable experience
Smart grid features
