This product complies with national standards GB1094-1996 “Power Transformers” and GB/T6451-2008 “Technical Parameters and Requirements for Three-Phase Oil-Immersed Power Transformers”. The S13~S22 series transformers are the latest low loss copper-wound products. They utilize high-quality materials and employ new processes and materials in the coil body and insulation, resulting in significant reductions in no-load and load losses, while enhancing reliability and performance.

Features:

1. Good Economic Performance

The S13~S22 series products are more energy-efficient compared to the S11 series. For instance, the average no-load current of the common S20 type transformer decreases by 60% to 80% compared to the previous S11 type, with no-load losses reduced by an average of 25% to 35%.

2. Long Service Life

The transformer tank adopts a fully sealed structure, with the tank and box edges connected by bolts or welded, preventing the transformer oil from contacting air and extending its service life.

3. High Operational Reliability

Improvements to the sealing of the tank components enhance reliability and improve the process level to ensure sealing effectiveness.

4. Compact Footprint

The S13-M and S22-M series transformers feature a corrugated plate radiator. When oil temperature changes, the thermal expansion and contraction of the corrugated plates can replace the function of an oil storage tank, resulting in a compact and aesthetically pleasing tank design.
