About transformers
Distribution Transformers
Distribution Transformers from 10 KVA to 5000 KVA which can be modified as per consumer
needs. They can be made in using Aluminium and copper both. CRGO and Amorphous core
can be used. They can be designed in 3 phase and 1 phase both. They can be designed using
Offload Tap changer and Onload Tap Changer upto 33 KV Class. They can be oil as well as air
cooled transformers. Types of Distribution Transformers are:
- Normal Distribution Transformers: Generally used by Industrial Clients, EPC Contractors, Real Estate Developers, Hotels, Restaurants, Shopping Complexes and State/Central PSUs. Nominal Voltage is either 11 KV or 33 KV.
- Station Transformers: They are generally used by State/Central PSUs or by Big Industries, EPC Contractors, Big Real Estate Developers or Big shopping malls. Generally, they are purchased by customers having sanctioned load of more that 1000 KVA. Nominal Voltage is 33KV.
- Step Up Transformers: They are transformers used by Generation Plants, Solar Plants etc, in which they convert lower voltage to higher voltage so that it can be used for transmission.
Power Transformers
from 1 MVA till 40 MVA upto 132 KV Class. They are made of copper
winding with CRGO Core. They can be designed using Offload and Onload Tap Changer. They
are Oil Cooled Only.
Auxiliary Transformers
They are used specifically by Indian Railways for transmission
purposes. They are special category transformers which are single phase having input at
25000 V and output at 240 Volts. We are CORE approved vendor for the same in standard
ratings of 5 KVA, 10 KVA and 25 KVA. They are copper wound having CRGO Core.
Special Purpose Transformers
They are special purpose transformers such as Booster
Transformers, Isolation Transformer, Furnace Type Transformers, Auto Transformers, DeltaDelta Transformers, Solar Duty Transformers, Extra High Voltage Transformers which are used
by specific industries for specific work. They are custom made and can be designed as per
customers technical needs.
We also have switch gear divisions in which we manufacture Servos, HT-ACBs, Compact
Substations and RTCC Panel for our clients.
About Our Transformers
Electrical transformers are devices that are used to transfer electrical energy from one circuit to another through the principle of electromagnetic induction. The manufacturing of electrical transformers involves several processes that include design, winding, core construction, insulation, testing, and assembly.
The first step in transformer manufacturing is the design process, which involves determining the specifications and requirements of the transformer such as voltage, current, frequency, and power rating. The design also involves determining the number of windings required, the core size and shape, and the type of insulation to be used.
Once the design is finalized, the winding process begins. This involves winding the copper wire around the core to create the primary and secondary coils. The number of turns and wire gauge are carefully calculated to ensure that the transformer meets the required specifications.
The core construction process involves laminating thin sheets of steel to reduce energy losses due to eddy currents. The laminations are then cut to the required shape and size and assembled to form the core.
The insulation process involves insulating the windings and core to prevent electrical breakdown and improve efficiency. Various types of insulating materials such as paper, varnish, and oil are used depending on the transformer’s design and application.
Once the transformer is constructed, it undergoes rigorous testing to ensure that it meets the required standards and specifications. The testing process includes measuring the transformer’s voltage ratio, resistance, insulation resistance, and leakage current.
Finally, the transformer is assembled and packaged for shipment to the customer. The packaging includes protective covers and shock-absorbing materials to ensure that the transformer is not damaged during transportation.
In conclusion, the manufacturing of electrical transformers is a complex process that requires specialized knowledge and expertise. The transformer’s design, winding, core construction, insulation, testing, and assembly must be carefully executed to ensure that the transformer meets the required specifications and standards.

Innovations
- The transformer industry has been evolving rapidly in recent years with the advent of new technologies and innovative approaches. One of the most significant innovations in the transformer industry is the development of smart transformers or digital transformers.
- These transformers incorporate advanced sensors, communication systems, and data analytics to enable real-time monitoring and control of power flow, voltage regulation, and other critical parameters. They can also provide valuable insights into the health and performance of the transformer, which can help utilities optimize their maintenance schedules and reduce downtime.
- Another area of innovation in the transformer industry is the use of new materials and design techniques to increase efficiency and reduce losses. For example, the development of amorphous metal alloys for transformer cores has led to significant improvements in energy efficiency and reduced operating costs.
- In addition to these technological advancements, there is also a growing trend towards greater integration of renewable energy sources into the power grid. This has led to the development of specialized transformers that can handle the unique requirements of renewable energy sources, such as solar and wind power.
- Overall, the transformer industry is undergoing a period of significant innovation as it adapts to the changing needs of the power grid and the demands of the modern world.
