Techno Tech Energy manufacturers power transformers from 3.0 MVA 33/11, KV Upto 15 MVA, 66 KV voltage class. All transformers can be supplied with the desired tappings for positive / negative voltage variation either with OFF circuit or ON load tap changers. We can also manufacture intermediate sizes with non standard voltage ranges as per customer requirements. We currently in operation in several power utilitiess playing an important role in efficient transmission and distribution of electricity.
