Product Description

Megawin Cast Resin Transformers are dry type transformers, supplied in sheet steel enclosure suitable for either indoor or outdoor installation and are Air.

Natural (AN) cooled. Higher ratings for hot environments are supplied with forced cooling as well. They are suitable for cable termination on HT side and LT side. Bus-Duct termination is also offered on LT side.

Product Features

  • It is compact and maintenance free

  • Resin casting provides much better dielectric strength and short circuit withstand capability

  • It has negligible partial discharge due to epoxy casting under specialized vacuum process with HV/LV winding separately cast

  • The foil winding in LV makes it withstand higher short circuit forces owing to negligible axial force components

  • Off circuit Tap changing links are a standard feature. Dry Type On-load Tap changing Gear can also be supplied


  • High- rise buildings

  • Congested locations

  • Fire hazard areas like mining, oil and gas etc.

  • In urban areas where cost of real estate is high
