  • First SF6-free voltage transformers for 420 kV

    The insulation medium of the blue instrument transformers has no impact on the environment, therefore the Global Warming Potential is zero. SF 6 or other fluorinated gases, called F-Gases, are replaced by applying dry synthetic air, so called „clean air“, as an insulation medium for gas-insulated equipment. Clean air consists of 80% nitrogen and 20% oxygen, natural elements in the
