Dry Type Transformers Indian Manufacturers Explaining The Concept Of Using Their Products

Like all electrical distributing equipments, transformers are also considered as key components for the users. This is why major manufacturers recommend a deep research to be done in order to get the most reliable contact to source transformer equipment, including dry type transformers in India and abroad. There are certain things to consider while specifying or buying any primary dry type range, which typically feed a large industrial plant, data center, or other critical industrial environment.

Dry Type Transformers Indian Manufacturers

  • Capacity – it is the kVA rating of the product transformer
  • Voltage rating – Primary and secondary voltage of the transformer
  • Insulation system
  • Winding insulation system
  • Core and coils

Large size dry type transformers are usually equipped with medium-voltage power systems and feature 480V (secondary voltage rating), 3 phase. Manufacturers are also supplying other sizes such as 500kVA, 750kVA, 1000kVA, 1500kVA, 2000kVA, 2500kVA, 3000kVA, etc.

Manufacturers and suppliers are using several different construction methods to build wide range of transformer models that can be further installed in distinct environments. The major difference in the design of these transformers is in the insulation of the windings.

Dry transformers can have numerous types of windings

  • Open wound
  • Vacuum pressure impregnation
  • Vacuum pressure encapsulated
  • Sealed
  • Cast coil

Every type of winding insulations mentioned above is suitable for specific environments. Hence, it is necessary for you to understand which one to select and use for certain environment. Whatever specific transformer device is required, major limiting factors you can consider can be heat, safety, and maintenance.

To make heat dissipation better Dry type transformers manufacturers in India incorporate a design with greater internal clearances. Engineers design these transformers with no fireproofing, oil catch basins or toxic gasses venting. These transformers can be close to the load, which minimizes secondary line losses. These transformers also lower maintenance and users don’t need to replace transformer oil often.
