Power transformers are defined as those transformers that are used to raise or lower voltages in the supply networks of power systems which serve to transmit electric power over great distances and distribute among the customers. Power transformers are notable for their high power capacity and operating voltage. Our range includes the manufacture of power transformer upto 16 MVA 110KV. The main and service parameters are given in the appropriate national standard specifications and only those transformers which meet the requirements of the standards are alloed for series production. We bring in innovations in all our designs that enablesus to produce quality tranformer every time.

Distribution transformers change the feeder voltage to utilization voltage required by the consumer. They are essentially step down transformer which changes the voltage to standard service voltage. Lower rating transformers are very well known as distribution transformers. It ranges up to 2500KVA 11KV since these transformers are operated throughout a day, even though they are not carrying load r not, it should have a good  all day efficiency.

Fabricated using superior quality cast iron, copper and steel as per IS and IEEE standards, our range finds application in household, commercial as well as industrial sectors. Our transformers can be provided with new technology embedded in it to meet individual requirements for new installation, replacement and others.

A high current furnace transformer is provided having the low-voltage windings arranged in a closed delta configuration within the transformer enclosure. Compact in size and durable, our range is manufactured from superior quality raw materials. Finding its applications in induction furnace industries for the purpose of induction heating process, our furnace transformers ensure trouble free performance. Widely in demand owing to its features, these can be customized as per the specific requirements of our clients.

Windmill transformers are those which require frequent switching operations and voltage variances. We offer our range of Windmill Transformer that can cater to the power requirement of more than 900 windmill projects across the country. Manufactured using qualitative iron and steel, our range is durable and precision engineered.

We fabricated ESP transformers that are durable and corrosion resistant using high quality raw materials. Used for electric submersible pumps, our range is compact and safe to use as it is designed as per IS and IEEE standards. Available in different watts, our range can be customized as per the specific requirements of our clients.
