GE Vernova's T155 Dual Gas GIS meets the challenges of networks up to 420 kV for power generation, transmission, and heavy industry applications.

Ready for future SF₆ gas regulations

Anticipating future SF₆ regulations, this Dual-Gas equipment is available with either g³ or SF₆ gas as an insulating and switching medium. Based on having the same foundational design, Transmission System Operators (TSOs) can buy the SF₆ version today and easily switch to GE Vernova’s g³ solution at a later time.

The T155 Dual Gas GIS is very compact and accessible, with a bay footprint equivalent to the previous SF₆ T155 model. Complete bays are fully assembled in the factory (wired, tested, packaged, and shipped), enabling shorter site works.

In addition, the T155 Dual-Gas GIS features an advanced SF₆ sealing system with a sealing length divided by two compared to the previous version, improving tightness.

Full digital monitoring control and protection capabilities enable the T155 Dual Gas to be readily integrated into the smart grid.
