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
-
High- rise buildings
