Power Transformers: Efficient Energy Transmission
TMR Transformers delivers advanced power transformers designed for high-voltage, heavy-duty applications. Ideal for power plants, aerospace, and industrial facilities, our transformers efficiently manage voltage levels to ensure reliable and stable power distribution.
Power Transformers
TMR Transformers is a Bangalore-based manufacturer of power transformers engineered for high-voltage transmission and heavy-duty industrial applications. As a manufacturer — not merely a reseller — we design, wind, assemble and test each unit in-house, stepping voltage up or down so electrical energy can be transmitted efficiently over long distances and distributed with minimal loss.
Our power transformers are built with cold-rolled grain-oriented (CRGO) silicon-steel cores, high-grade copper or aluminium windings and robust insulation systems, with capacities reaching up to 25 MVA and primary voltages up to 132 kV. Units are offered in three-phase configurations at 50 Hz or 60 Hz with ONAN and ONAF oil cooling, and every transformer is routine-tested for turns ratio, insulation resistance and load and no-load losses before dispatch.
Typical applications include generating stations, substations, aerospace and defence facilities, and large industrial plants where a stable, reliable supply is critical. Customers choose TMR for custom-engineered ratings, low core and copper losses, excellent heat dissipation and long service life, backed by responsive after-sales support across India and worldwide.

Frequently asked questions
- What is a power transformer used for?
- A power transformer steps voltage up or down at high voltage levels so electrical energy can be transmitted efficiently over long distances between generating stations, substations and large industrial loads. Raising the voltage lowers the current for a given power, which reduces transmission losses.
- What is the difference between a power transformer and a distribution transformer?
- Power transformers operate at higher voltages and larger capacities and are used in transmission networks and at substations, often running near full load for much of the day. Distribution transformers work at lower voltages closer to the end user and are sized for varying daily loads.
- What capacity and voltage do TMR power transformers cover?
- TMR manufactures three-phase power transformers with capacities up to 25 MVA and primary voltages up to 132 kV, at 50 Hz or 60 Hz with ONAN or ONAF cooling. Ratings are custom-engineered to each project's requirements.
- Is TMR a power transformer manufacturer or a reseller?
- TMR Transformers is a manufacturer. We design, wind, assemble and test power transformers in-house at our Bangalore facility and supply directly to customers across India and worldwide, which lets us tailor ratings and offer responsive after-sales support.
