Oil Cooled Distribution & Power Transformer
RANGE : Up to 10000 KVA in 11 and 33 KV Class
General Information
The distribution & power transformers are used for converting electrical energy with higher voltage to lower voltage. Generally the higher voltage falls in the range of 11-22-33kV whereas lower voltage falls in 250 or 433V range. The frequency remains identical before and after the transformation of the current.
All the distribution & power transformers are approved by reputed National Inspecting Agencies like Engineers India Limited, RITES, Department of Industries, Haryana, CIL, SGS, CPWD, NIT and many other bodies.
