Oil immersed transformer
Advantages of Overload Transformers:
Efficient and energy-saving: in line with the new national standard S13 energy efficiency, the no-load loss is reduced by about 25% compared to S11, and the annual operating cost is significantly reduced.
Strong overload capacity: Optimized heat dissipation design, allowing short-term overload operation (such as 110% load), adapting to power grid fluctuations.
Fully sealed structure: maintenance free fuel tank, moisture and oxidation resistance, extended lifespan (>20 years).
Low noise environmental protection: ≤ 50dB (national standard limit), suitable for residential areas/industrial and mining enterprises.
The user emphasized the "oil immersed" and "overload" capabilities, indicating a focus on heat dissipation performance and emergency carrying capacity. Three points need to be highlighted:
1) Fully sealed structure for anti-aging (oil immersed core advantage);
2) S13 energy efficiency standard is more energy-efficient than S11 (national standard upgrade point);
3) Overload design allows for short-term overload (in response to sudden demand).
Key parameters:
Capacity: 3150KVA
Voltage: 10 ± 2 × 2.5% KV (high voltage side)
Loss: No load ≤ 930W, load ≤ 26600W
Connection group: Dyn11 (harmonic suppression)
Cooling method: ONAN (oil immersed self cooling)
Applicable scenarios: High reliability power supply scenarios such as urban power distribution, heavy industry, and new energy power stations.
