Our transformers division was formed by the takeover of western transformers bringing in over four decades of manufacturing and technical excellence to the fold. We have three fully-integrated facilities in Gujarat with in-house facilities for products such as core laminations, wire drawing, strip mill, winding and a transformer oil refinery. We also have a world class Dry Type Transformer Facility. To further fuel growth, fresh investments in technology, capabilities and capacities have been made in this division.
Our transformer range comprises of state-of-the-art power, distribution and dry-type transformers, ranging from 11KV to 220KV, all the way up to 325MVA. Each of our transformers undergo stringent Type-Testing at labs such as ERDA, ensuring high efficiency and reliability.
