Technical Data;

Voltage Range: Up to 72,5kV
Power Range: Up to 20MVA
Core: Cold Rolled Grain-Oriented Silicon Steel
Windings: The windings may either be copper, aluminium upon the customer’s request.

Drying: The active parts of transformers are dried under a high vacuum in a furnace. The process of drying varies according to the transformer type, power, and voltage. Oil is filled under a high vacuum.

Tank: Tanks and top covers for transformers are made of mild steel. Cooling surfaces of distribution transformers areconstructed with corrugated walls and they also form the lateral surfaces of the tank. The bottom plate, sides, and frame are sealed by welding.

Standard Code: IEC 60354, DIN 42500-BS 50464
