High-Efficiency & Energy-Saving Core
Made of high-grade grain-oriented silicon steel, significantly reducing no-load loss and ensuring low operating cost.
Corrugated Tank for Superior Heat Dissipation
The full-wave corrugated radiator design enlarges the heat dissipation area, keeping the transformer cool under continuous heavy load.
Fully Sealed & Leak-Proof Structure
Precision-welded tank and high-quality sealing gaskets ensure long-term oil leakage prevention and reliable outdoor operation.
Robust Conservator Tank Design
The conservator tank stabilizes oil level and isolates the oil from air, extending oil service life and preventing moisture ingress.
High-Voltage Porcelain Bushings
Anti-pollution, high-strength porcelain bushings ensure safe and stable connection on both HV and LV sides.
Low Loss, Low Noise Operation
Optimized magnetic circuit and core clamping structure reduce noise and losses, meeting international energy efficiency standards.
Wide Capacity Range Available
Available from 10 kVA to 2500 kVA, suitable for utility, industrial, commercial, and rural power distribution networks.
Strict Quality Control & Testing
100% routine tests including ratio, resistance, insulation, and oil dielectric strength before shipment.
Customizable Voltage Ratio & Tapping
Offers various voltage combinations and off-circuit / on-load tap changing options to match local grid requirements.
Long Service Life & Low Maintenance
Durable anti-corrosion coating, reliable structure, and minimal maintenance needs for 20+ years of service.

Product Q&A
Q:What is the capacity range of this oil-immersed distribution transformer?
A:
We can supply from 10 kVA to 2500 kVA, covering single-phase and three-phase types. Customized capacities are also available upon request.
Q:Is this transformer fully sealed or with a conservator tank?
A:
Both designs are available. The model shown uses a conservator tank for oil level stabilization. We also produce fully sealed types for specific applications.
Q:What are the no-load loss and load loss levels?
A:
Our transformers are designed to meet international energy efficiency standards (such as IEC 60076 and local IE2/IE3 equivalents). Exact loss values depend on capacity and voltage class please contact us for the detailed technical datasheet.
Q:Do you provide tap changing?
A:
Yes. We offer both off-circuit tap changer (manual, de-energized) and on-load tap changer (OLTC) options, depending on your requirements.
Q:What cooling method does this transformer use?
A:
It uses oil natural air natural (ONAN) cooling. The corrugated tank design increases the heat dissipation area for reliable continuous operation.
