Underground Buried Transformer, 12 kV (Um 12 kV), 100–1250 kVA — DMB-12

Where surface space simply does not exist, the transformer goes below it. The DMB-12 is built for direct burial in a sealed concrete chamber: the tank, HV connections and cooling path are protected against ground water and soil load, while the LV cabinet remains at grade for operation and maintenance. Typical applications are city squares, boulevards and historic districts where nothing may be seen.
