Description
The range of rated voltages covers 72.5, 145, 170, 245/300, 362, 420, 550 and 800 kV, from high to extra-high voltage networks. A narrow bay simplifies the substation layout on a limited site and in a building. Gas leakage is below 0.1 % per year. For the 170 kV class there is an eco-friendly version using a Novec 4710 + CO2 mixture. The equipment has been tested at the KERI, CESI and KEMA laboratories.
