Project Innovation + Advantages:

GE Grid Solutions plans to develop a SF6-free high-voltage AC outdoor dead-tank power circuit breaker. The circuit breaker will be rated at 245 kV and will also provide the basis for a two-break 550 kV rated design. It will use g3 TM gas mixture for current breaking and dielectric withstand. This project is a critical step in launching a range of products that meet U.S. energy industry requirements without using SF6 technology. These products are essential to reduce the bulk electric system’s carbon footprint and greenhouse gas emissions. The resulting products will be manufactured in the U.S.
