Overview
T155 DUAL GAS GIL
One 420 kV GIL design for SF₆ and SF₆-free
GE Vernova's Grid Solutions offers cutting-edge gas-insulated lines (GIL) up to 420 kV designed for both SF6 and SF6-free applications, leveraging more than 60 years of expertise in gas-insulated substation technology. This unique flexible design allows transmission system operators (TSOs) to purchase the SF6 version initially with the option to transition easily to the SF6-free g³ solution, ensuring compliance with emerging regulations on fluorinated greenhouse gases without compromising operational performance.
