Oil-Immersed Transformers
100 – 2500 kVA10 kV / 0.4 kV

Where electricity is expensive or the load factor is low, the S22-M pays for its premium within a few years. Grade-1 energy efficiency is achieved with high-grade grain-oriented silicon steel and a tightly controlled step-lap core, cutting both no-load and load losses to the lowest level available in a liquid-filled distribution unit.
