Distribution Transformers

Transformer is an electrical device which, by the principles of electromagne induction, transfers electrical energy from one electric circuit to another, without changing the frequency. The energy transfer usually takes place with a change in voltage and current. Transformer either increases or decreases AC voltage. Om Electrical Power Solutions is supplying wide range of oil cooled distribution and medium power transformers and is offering a complete electrical solution to customers. we are focused to cater the requirements of private & industrial customers and offers best & optimal solution to the situation. Due consideration is given to understand the requirement, and thereafter our marketing team offer appropriate solution to the situation.
