Unimacts offers a complete range of transformers, including distribution, power, and dry-type models, tailored to meet the needs of industrial, renewable, and infrastructure projects. Built to meet global standards, our transformers are engineered for reliable operation, reduced energy losses, and long-term durability. With advanced manufacturing processes and strict quality control, we deliver solutions that ensure efficient power distribution and seamless operations for critical applications.
We manufacture both hermetically sealed, corrugated radiator type and conventional rectangular tank type distribution Transformers. These Transformers are generally used in distribution network for feeding residential, commercial & bulk consumers.
Pad Mounted Substations are designed for use in distribution application as well as dedicated loads. Pad Mounted Substations are easy to install and are low cost. These are the most basic and simplest configuration required for distribution substations. Pad Mounted Substations are designed in accordance with IS 14786 / IEC 61330 standards with degree of protection for IP 54 or as per customer requirement.
At Unimacts casting method of these transformers is obtained with the combined action of vacuum and temperature. The casting method makes it possible to assure void-free epoxy penetration of both the inner layer and between turn insulation. These transformers are specifically needed in distribution network for feeding basements or stilts of high-rise buildings, hotels, malls, stadiums, airports, or chemical & refinery plants. Following are the dimensional, weight & quantity details along with standard losses for conventional 11KV, Dry Type (VPI) Transformer (off circuit Type).
All the transformers of rating above 5MVA and primary voltage class from 11kV to 66kV are conventionally termed as Power Transformers. These transformers are generally used for stepping down voltage in receiving stations in distribution network.
Unitised substations are designed for locations where space and safety is a concern, population density is high, such as an urban center. Unitised substations are divided in three sections or compartments as: Medium Voltage, Transformer and Low Voltage Switchboard. Unitised substations are designed in accordance with IS 14786 / IEC 61330 standards with degree of protection for IP23 for Transformer and IP 54 for MV & LV compartments or as per customer requirement.
We at Unimacts manufacture both hermetically sealed, corrugated radiator type and conventional open enclosure type vacuum pressure impregnated dry Transformers. These Transformers are specifically needed in distribution network for feeding basements or stilts of high-rise buildings, hotels, malls, stadiums, airports, or chemical & refinery plants. Weight & quantity details along with standard losses for conventional 11KV, Dry Type (VPI) Transformer (off circuit Type).
Tower substations are designed for use in distribution application as well as for dedicated loads. Tower substations are easy to install and low cost. These are the most basic and simplest configuration required for distribution substations. Tower Substations are designed in accordance with IS 14786 / IEC61330 standards with degree of protection for IP 54 with ONAN transformer & with Dry / Cast resin transformer only transformer enclosure with IP23 or per customer requirement.
Containerised solar substation are designed for clustered solar parks where space and safety is a concern, and are of capacity 500KW to 20MW projects. Containerized substation is divided in three section or compartment— MV Breaker, Transformer and Inverters with DCDB. Containerised substations are designed in accordance with IS 14786 / IEC 61330 standards with degree of protection upto IP 43 for Transformer and Inverters compartments & upto IP 54 for MV breaker compartment. Following are the dimensional and weight details for a typical11kV, Containerized substation with off circuit type Dry / Oil Cooled Transformer.
Conventionally oil cooled Transformers are categorized into Extra High Voltage, Power & Distribution Transformers. All the Transformers of primary voltage class from 66kV and above are conventionally termed as Extra High Voltage (EHV) Transformers. These transformers are generally used for stepping down voltage from Transmission lines. EHV transformers generally have force cooling and on load tap changer. We at Unimacts, have facility to manufacture up to 50MVA, 132kV Class EHV Transformers.
At Unimacts, we bring expertise and innovation to precision manufacturing across the renewable energy sector.
Unimacts is ISO 9001/2015 certified and our UOS (Unimacts Operating System) is based on Lean Six Sigma. Our materials, welding and coating processes are typically based on ASTM, AWS, or EN specifications. These industry certifications help ensure that your solar projects are built to and uphold the highest quality and performance standards.
