For higher capacities, banks of three single-phase units are deployed, offering versatile and scalable power solutions.

Technical Specifications

  • Capacity Options: Available in 3-phase system up to 12.5 MVA and single-phase banks for higher ratings.

  • Voltage Rating: Up to 33KV for both Arc and Ladle Refining Furnace Transformers.

  • Star-Delta Arrangement: Includes either six bushings or motorized star-delta switches for smooth operation.

  • Ladle Refining Transformers: Specifically designed up to 12,500 KVA with robust voltage handling.

  • Construction Type: Built to withstand high thermal and mechanical stress during steel melting operations.

Types

Three phase units are available in three ways

  • Tap windings are in series with main HT windings in one core frame and in one tank with OLTC.
  • Tap windings are separated through auto transformer in addition to main transformer, but both the transformers are in one common tank.
  • Tap windings are through an auto transformers in separate tank with OLTC and main transformer is in another tank.

Single phase units are available in three ways

  • Three single phase units having each unit, consisting of Tap windings in series with main HT windings in one core frame and in one tank with OLTC.
  • Three single phase units having each unit consisting of separate Tap winding through Auto Transformer in addition to main transformer to main transformer and in one tank with OLTC.
  • Three single phase units having each unit consisting of only main transformer. The OLTC & three phase auto transformer shall be in separate tank.

FAQ

Which transformer is used in an arc furnace?

An Arc Furnace Transformer, typically an oil-immersed step-down transformer, is used in an electric arc furnace. It converts high-voltage input to low-voltage, high-current output necessary for the arc generation, enabling efficient melting of metals in steel plants and foundries.

What is the purpose of a furnace transformer?

A furnace transformer is designed to supply the high-current, low-voltage power required for melting and heating metals in industrial furnaces. It ensures stable electrical output, controls thermal load variations, and withstands frequent short-circuit conditions during the furnace’s operational cycles.

Which transformer is used in arc welding?

An arc welding transformer is a step-down transformer that reduces high-voltage input to a low, safe voltage with high current. It is used in manual and automatic arc welding applications to generate the arc necessary for joining metals through intense localized heating.
