10kV Distribution Transformer: 

This product conforms to national standards GB1094-1996 "Power Transformers" and GB/T6451-2008 "Technical Parameters and Requirements for Three-Phase Oil-Contained Power Transformers". The S13-S22 series transformers are a new series of low-loss copper winding products. These products utilize high-quality materials and employ new processes and materials in the coil body and insulation, resulting in significantly reduced no-load and load losses, and more reliable and superior performance and structure.

Features of the S13~S22 Series 10kV~35kV Low-Loss No-Excitation Voltage Regulating Transformers:

**Good Economic Performance:** Compared to the S11 series, the S13~S22 series reduces no-load loss by an average of 30%, and the no-load current is reduced by 70%-85% compared to the S11 series.

Long Service Life: The transformer tank adopts a fully sealed structure. The tank and its edge can be bolted or welded together, preventing the transformer oil from contacting air and extending its service life.

High operational reliability: Improvements have been made to the sealing components of the oil tank, increasing reliability and enhancing the manufacturing process to ensure reliable sealing.

Small footprint: The S13-M and S22-M series transformer oil tanks use corrugated plate radiators. When the oil temperature changes, the thermal expansion and contraction of the corrugated plates can replace the function of the oil conservator. The corrugated plate oil tank has an aesthetically pleasing appearance and a small footprint.
