Product Description
Megawin Cast Resin Transformers are dry type transformers, supplied in sheet steel enclosure suitable for either indoor or outdoor installation.
- 
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
 
Application
