Product Description

Rajkot Powertrans Private Limited is a big name that deals in the manufacturing and supplying of Oil Cooled Power Transformer that is commonly used in industrial and commercial buildings to control electrical and transfer electrical power. It is installed with safety units such as surge arresters, high voltage circuit taps, and many more. This electrical machine is capable to deliver power in between 3000 to 10000 Kilo-volt ampere. Oil Cooled Power Transformer has a copper core that greatly diminishes the power loss within the circuitry.
