UPT provides a comprehensive range of distribution transformers, both newly manufactured and re-engineered. Our transformers are in accordance with internationally recognized standards and come with industry leading guarantees for complete peace of mind.
We are occupied in designing, manufacturing and supplying high quality 10, 25, 63, 100, 160, 250, 400 & 630 Kva, 11/0.433-0.250Kv Three Phase Distribution Transformers, backed by unparalleled expertise of our professionals having an extensive experience of over 35 years. Any specific rating can also be manufactured as per the customer requirements.
These products are manufactured using advanced technology and components. The transformers confirm to relevant ISS as well as three star rating energy efficient transformers. The transformers are exclusively designed as per customer requirements, having aluminium or copper windings. The standard ratings / design of these transformers is periodically type tested at CPRI, Bhopal. Further each and every transformer is tested for all the parameters of efficiency, performance and durability as provided by IS-2026.
