Oil-immersed distribution transformers deliver superior cooling, extended lifespan, and strong overload capacity, making them essential for industrial, commercial, and renewable energy applications.
We provide 10kVA~10MVA oil-immersed transformers to meet diverse power distribution needs, ensuring safer, more energy-efficient, and stable electricity transmission.
Why Choose Oil-Immersed Distribution Transformers?
✅ Excellent Cooling for Stable Performance
Uses mineral oil or synthetic ester fluid for high heat dissipation, ideal for long-term heavy-duty operation.
Fully sealed design resists moisture and dust, suitable for outdoor, industrial, and substation environments.
✅ High Efficiency, Low Energy Loss
Complies with GB 20052, IEC 60076 standards, reducing no-load loss by over 20% for cost-effective operation.
Copper or aluminum windings available to fit different budgets, lowering lifetime costs.
✅ Durable & Low-Maintenance
30+ years of service life, robust construction, and strong short-circuit resistance.
Built-in oil temperature monitoring and pressure relief valves for minimal maintenance and downtime.
✅ Customizable for Various Applications
Supports step-up, step-down, and isolation functions, perfect for:
Renewable energy plants (solar/wind grid connection)
Industrial power distribution (factories, mines, petrochemical plants)
Urban grids (commercial complexes, residential substations)
