The TM 25-2500 series are three-phase oil-immersed distribution transformers covering the rated power range from 25 to 2,500 kVA at 6-10 kV primary voltage. The traditional design with an expansion tank is the most widely deployed class of distribution transformer in Kazakhstan.
Step-down service in municipal, industrial and agricultural networks; suitable for both packaged substations (KTP) and indoor transformer halls.
Grain-oriented silicon-steel core, copper or aluminium windings, mineral-oil cooling, conservator (expansion) tank with silica-gel breather, on-load or no-load tap changer (NLTC) on the high-voltage side.
