T210
Gas-Insulated Substations up to 800 kV
GE's T210 GIS is a field-proven solution with high availability that meets the challenges of networks up to 800 kV for power generation, transmission, distribution, tertiary and heavy industry applications. The T210 is one of the most compact GIS solutions available at 800 kV with a footprint 65% below the market average. It is comprised of small, light components making it easy to handle.
The T210 is environmentally friendly and features one of the lowest gas weights on the market along with an advanced SF₆ sealing system. Full digital monitoring control and protection capabilities enable smart grid integration.
Building on GE's GIS experience of more than 50 years, the T210 provides high availability and current transformers outside SF₆.
