More and more electrical grid operators are taking action against climate change and are setting ambitious goals to cut their greenhouse gas emissions.

Benefiting from more than 50 years of expertise in SF₆ and ten years in SF₆-free technology, we innovate in developing a range of SF₆-free products suitable for all climates, including temperatures down to -50°C.

Our GL309c, GL310c, GL311c and GL312c SF₆-free Live Tank circuit breakers are part of GRiDEA, our portfolio of solutions designed to accelerate the decarbonization of the grid. They enable considerable reduction in carbon footprint over the complete life cycle compared to the equivalent SF₆ range.

GL309c, GL310c, GL311c and GL312c help decarbonize networks for applications at 72.5 kV, 100 kV, 123 kV and 145 kV rated voltages. They are designed for outdoor installation, and they feature the same dimensions as SF₆ solutions, which means that they can be installed in place of SF₆ circuit breakers. Their transportation and handling are as easy as SF₆ circuit breakers.
