Innovative SF6-free Switch with Shunt Vacuum Interruption Technology
More than 30 million units of medium-voltage switchgear installed worldwide use sulfur hexafluoride (SF6), a potent greenhouse gas. Eliminating the use of SF6 is a significant step toward safer, more environmentally friendly switches. This paper discusses how, beyond boosting safety, an innovative new SF6-free technology is:
