12.5 MVA Three Phase Air Cooled Oil Immersed Power Transformer Applications

Industrial Facilities

Heavy industries such as manufacturing plants, steel mills, chemical refineries, and mining operations require stable, high-capacity power to run machinery (e.g., motors, compressors, and heating systems). The 12.5 MVA transformer steps down high-voltage grid power (e.g., 33 kV, 66 kV) to medium or low voltage (e.g., 11 kV, 415 V) for safe on-site use, ensuring uninterrupted production.

Utility-Scale Power Distribution

Electric utility companies rely on this transformer to upgrade or expand distribution networks. It is often installed in substation s to:
Step down transmission voltages (e.g., 132 kV) to distribution voltages (e.g., 33 kV) for supply to residential and commercial areas.
Support load growth in urban or suburban regions, where demand for electricity (from homes, offices, and EV charging stations) is rising.

Renewable Energy Integration

Solar farms and wind parks generate power at medium voltages (e.g., 10 kV) but need to feed it into the high-voltage grid (e.g., 66 kV, 132 kV) for long-distance transmission. The 12.5 MVA air cooled oil immersed transformer acts as a “step-up” unit here, converting low voltage to high voltage while withstanding the variable load conditions common in renewable energy systems. Its air-cooled design also works well in remote areas (e.g., desert solar parks) where water for cooling is scarce.

Commercial & Municipal Infrastructure

Large commercial complexes (malls, airports, data centers) and municipal facilities (hospitals, universities, wastewater treatment plants) demand consistent power to avoid downtime. The 12.5 MVA transformer provides a reliable power supply, even during peak usage (e.g., hospital surgery hours, mall holiday seasons), and its compact footprint fits in space-constrained urban settings.
