Oil filled power transformers are versatile electrical devices designed for power distribution in industrial, commercial, and utility networks. Available in ratings from 30 kVA (small-scale applications) to 2500 kVA (medium-sized grids), these oil transformers use mineral oil or synthetic ester as both insulation and coolant, ensuring efficient heat dissipation via natural convection (ONAN) or forced air cooling (ONAF for higher ratings). Built with low-loss silicon steel cores and copper/aluminum windings, they offer high efficiency (≥95%) and voltage stability (±5% tap adjustment). Key features include rugged steel tanks (IP54/IP66), Buchholz relays for fault protection, and compliance with IEC 60076, GB 1094 (China), or ANSI standards. Ideal for substations, factories, and renewable projects, they balance reliability and cost-effectiveness, with optional smart monitoring for remote diagnostics. Designed for 50/60 Hz systems, they operate in temperatures from -25°C to +45°C, ensuring durability in diverse environments.

Application of 30-2500 kVA Oil Type Power Transformer
30–2500 kVA Oil Type Power Transformers are widely used in medium-voltage power distribution systems across various industries and applications:
Industrial Sector: Power factories, manufacturing plants, and industrial complexes to step down/up voltage for machinery, lighting, and process equipment. Ideal for heavy-duty environments like steel mills, chemical plants, and cement facilities.
Commercial & Urban Infrastructure: Serve shopping centers, office buildings, hospitals, and residential complexes to ensure stable power supply for lighting, HVAC systems, and elevators. Critical for urban grid networks and substations.
Renewable Energy: Integrate with solar farms, wind parks, and biomass plants to match voltage levels for grid connection, especially in remote or rural areas where reliable distribution is essential.
Utilities & Substations: Act as distribution transformers in utility grids, enabling efficient power transfer from transmission lines to end-users. Suitable for both overhead and underground installations.
Mining & Heavy Machinery: Power mining sites, crushers, and conveyor systems in harsh, dusty environments, thanks to their robust oil-cooled design and fault-protection features (e.g., Buchholz relays).
Agriculture & Rural Areas: Support irrigation systems, grain processing facilities, and rural electrification projects, offering durability in fluctuating loads and outdoor conditions.
These oil type transformers excel in applications requiring high reliability, efficient heat dissipation (via ONAN/ONAF cooling), and compliance with global standards (IEC 60076, ANSI, etc.), making them a versatile choice for both small-scale setups (30 kVA) and medium-sized grids (2500 kVA).
