Transformer

Oil-Immersed Transformers

Double-winding type separates the input voltage and output voltage into two independent windings.
It is manufactured in Y (wye) or Δ (delta) connection, ensuring insulation between the primary and secondary sides, and is constructed using a terminal block method.

  • It is manufactured with a natural cooling (air-cooled) system.
  • Indoor type.
