Our SF6 Free Products
SF6 Free Product
As part of SEL's ongoing innovation to provide effective solutions for environmental preservation, reduce gas emissions, and support the decarbonization process, SEL has developed a new three-position switch disconnector that is SF6-free, utilizing its own expertise and know-how.
New ECO-Friendly device
It is a new eco-friendly device that uses clean air as an insulating medium, free of SF6 gas. It has been designed to extinguish electric arcs using a vacuum interrupter. Through coordination with the movement of the three-position switch, it provides a solution for breaking/ opening, closing and earthing electric circuits in medium voltage networks. This new solution reduces greenhouse gas emissions and does not produce any toxic decomposition products during its operating process.
