Furnace Transformers


Transformers of this type are used in steel melting & metallurgical industry. They are characterized by high secondary current & a wide secondary voltage range. The secondary voltage is normally regulated by an on-load tab changer (OLTC) located in the high voltage winding or in an intermediate circuit of two-core design (booster regulation) within the transformer tank. Furnace transformers have secondary voltages up to 1500 v.
Furnaces transformer needs to be engineered for the various types of furnaces like:
  • ARC furnace
  • Ladle Furnace
  • Reduction furnace
  • Furnaces for special purposes.
  • DC furnace
