S13-S22 10kV-35kV Class Low-loss Off-circuit Tap-changing Transformer

Product Introduction

This product complies with the national standards GB 1094-1996《Power Transformers》 and GB/T 6451-2008《Technical Parameters and Requirements for Three-phase Oil-immersed Power Transformers》. The S13-S22 series transformers are a new range of low-loss copper winding products. Adopting high-quality materials, and applying new technologies and new materials in coil cores and insulation, the products achieve a significant reduction in no-load and load losses, with more reliable and superior performance and structure.

Features of S13~S22 Series 10kV~35kV Class Low-loss Off-circuit Tap-changing Transformers

Excellent Economic Performance

Based on the S11 series, the S13~S22 series products see an average 30% reduction in no-load losses, and their no-load current is 70%-85% lower than that of the S11 series.

Long Service Life

The transformer oil tank adopts a fully sealed structure, with the tank body and tank flange connectable by bolts or welded hermetically. The transformer oil is isolated from air contact, which extends the service life of the product.

High Operational Reliability

Relevant components for oil tank sealing have been improved to enhance reliability, and the manufacturing process level has been upgraded to ensure the reliability of the sealing performance.

Small Floor Area

The oil tanks of S13-M and S22-M series transformers are equipped with corrugated plate radiators. The thermal expansion and contraction of corrugated plates with oil temperature changes can replace the function of oil conservators. The corrugated plate oil tanks feature an aesthetic appearance and a small floor area.
