Key Advantages of the 23kV 3500kVA Low-Loss Oil-Immersed Transformer
1. Exceptional Energy Efficiency and Low Loss
Built with premium-grade, high-permeability silicon steel and an optimized electromagnetic structure, this transformer achieves remarkably low no-load and load losses. Its design complies with or exceeds international energy standards such as GB 20052 and IEC 60076, helping enterprises meet energy conservation and carbon reduction goals. The reduced power loss translates to substantial cost savings and long-term returns on investment.
2. 23kV Voltage Compatibility
The 23kV voltage level is widely adopted in medium-voltage power distribution networks, making this transformer ideal for industrial parks, infrastructure, and commercial facilities. It efficiently converts 23kV medium-voltage input into low-voltage outputs such as 400V or 230V for motors, lighting, and other industrial applications, ensuring smooth power distribution and equipment stability.
3. High Capacity for Industrial Applications
With a capacity of 3500kVA, this transformer supports medium-to-large power loads, suitable for manufacturing plants, data centers, hospitals, and airports. Optional features such as off-load tap changers (OLTC) enhance voltage stability under fluctuating operating conditions.
4. Proven Oil-Immersed Technology
The oil-immersed design ensures outstanding insulation, cooling, and overload capacity, providing a service life exceeding 25–30 years. Its sealed or fully sealed tank structure (e.g., corrugated tank) effectively prevents oil aging and moisture ingress, reducing maintenance frequency. Equipped with safety components such as pressure relief valves and Buchholz relays, the transformer guarantees safe, continuous operation.
Applications and Industries
Power Grid and Substations: Ideal for regional substations, grid upgrades, and public distribution systems.
Industrial Facilities: Suitable for steel, chemical, and cement plants, as well as large-scale equipment power supply.
Commercial and Public Buildings: Applied in commercial centers, hospitals, data centers, airports, and infrastructure projects.
Renewable Energy Systems: Efficiently supports photovoltaic and wind power step-up applications in green energy projects.
Selection and Purchase Guide
When selecting a 23kV 3500kVA transformer, consider the following factors:
Energy Efficiency: Verify loss measurement reports and energy efficiency level (e.g., Level 1 standard).
Impedance Voltage: Match the transformer’s short-circuit impedance (Uk%) with the system’s short-circuit capacity.
Cooling Method: ONAN (oil natural air natural) cooling is commonly used for stable performance under overload conditions.
Protection Grade: Choose the appropriate IP rating for indoor or outdoor installation environments.
Manufacturer Qualification: Partner with certified suppliers offering technical expertise and comprehensive after-sales service.
