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.

Distribution Transformers
TMR Transformers is a manufacturer of distribution transformers that step medium-voltage supply down to the low voltages used by homes, businesses and industry. Positioned at the final stage of the power network, these units deliver a safe, stable and continuous supply while keeping energy losses to a minimum. We manufacture distribution transformers with primary voltages of 11 kV, 22 kV and 33 kV in three-phase configurations at 50 Hz or 60 Hz, with ONAN, ONAF and AN cooling options. Built around low-loss CRGO cores and high-conductivity windings, our transformers offer high mechanical strength, strong short-circuit withstand, low partial discharge and good thermal stability. Each unit is manufactured and tested in-house to relevant IS/IEC standards. From residential feeders and commercial complexes to lighting plants and sensitive electronic loads, TMR distribution transformers are designed for cost efficiency and a long, low-maintenance service life. As a direct manufacturer we can tailor ratings, vector groups and fittings to your project. Request a quote for a distribution transformer matched to your load.

PMT - Pad Mounted Transformers
TMR Transformers manufactures pad-mounted transformers (PMT) — compact, ground-level distribution units housed in a tamper-resistant, locked steel enclosure and mounted on a concrete pad. With no exposed live parts, they can be installed safely in public and pedestrian areas without a fenced substation or elevated platform. We build pad-mounted transformers for capacities from 500 kVA to 10,000 kVA with primary voltages up to 33 kV, in three-phase, oil-immersed configurations at 50 Hz or 60 Hz. The fully sealed, dead-front design gives maintenance-free, weatherproof operation and steps high primary voltage down to the secondary levels required by utility and industrial customers, all within a compact footprint. Pad-mounted transformers are ideal for urban and residential distribution, commercial developments, campuses, and rural or space-constrained sites. As a direct manufacturer TMR can configure ratings, bushings and enclosure options to your specification. Request a quote for a pad-mounted transformer suited to your network.

Solar Transformers
TMR Transformers manufactures solar transformers purpose-built for solar photovoltaic (PV) power plants. In a PV plant the inverters produce alternating current from the panels; the solar transformer then steps this output up to the medium- or high-voltage level required to feed the grid, so energy can be evacuated efficiently with minimal loss. Because PV output fluctuates with sunlight, solar transformers must tolerate frequent load cycling, harmonics from the inverters and wide temperature swings. Our solar transformers are engineered with robust insulation, low losses and low noise, in three-phase configurations at 50 Hz or 60 Hz, with primary voltages configured to match the array and inverter output and oil-immersed or air-cooled designs to suit the site. Custom cabinet and rating options are available for each project. Whether for utility-scale solar farms, rooftop and commercial installations or hybrid renewable systems, TMR solar transformers maximise energy yield, support reliable grid integration and include protective features that safeguard the plant. As a manufacturer we tailor every unit to your PV design. Get a quote for a solar transformer for your installation.

Hermetically Sealed Transformers
TMR Transformers manufactures hermetically sealed transformers built with a completely sealed tank that isolates the insulating oil from the surrounding atmosphere. Because no air or moisture can enter, the oil does not oxidise or form sludge, so its dielectric strength is preserved and the transformer delivers a long, maintenance-free service life. There is no conservator tank or breather to service. The sealed tank accommodates the oil's thermal expansion either through flexible corrugated fin walls or an inert nitrogen-gas cushion above the oil, keeping the unit fully protected in harsh, humid, dusty or chemically aggressive environments. Our hermetically sealed transformers are offered in three-phase configurations at 50 Hz or 60 Hz with ONAN, ONAF and AN cooling, and primary voltages configured to customer requirements. Each unit is stringently inspected and precision-engineered for dimensional accuracy and leak-tight integrity. These transformers are well suited to chemical and process plants, coastal and high-humidity sites, and large power projects where reliability and minimal maintenance are essential. As a manufacturer, TMR can match ratings, fittings and protection to your application. Request a quote for a hermetically sealed transformer.

Compact Sub Station - CSS
TMR Transformers offers advanced Compact Substations (CSS) designed for efficient and reliable power distribution. These substations integrate all necessary components, including transformers, switchgear, and protection devices, into a single, compact unit. Ideal for urban and industrial applications, our CSS solutions provide a cost-effective and space-saving alternative to traditional substations.
