SF6 End-of-life pipes for Very High Voltages

SF6 End-of-life pipes for Very High Voltages

Reliability until the end of the service life. The first high-voltage GIS and SF6 insulating gas entered the market in the 1960s. The combination is still functional and reliable, and Fingrid has no intention of abandoning it overnight. New technologies will become more widespread on the grid in the coming decades.
