First Sulfr hexafluoride-free voltage transformers - Siemens Energy Global

Worldwide, many TSOs intend to eliminate greenhouse gases for new installations of gas-insulated equipment and therefore continue to contribute to their voluntary self-commitment in SF 6 reduction. Until now, SF 6 -free voltage transformers were available for voltages up to 245 kV. Recently, Siemens Energy has succeeded to expand the Blue portfolio, which exists of a broad spectrum of CO 2 equivalent-free equipment for air-insulated and gas-insulated switchgear, with a 420 kV voltage
