Manufactured in strict accordance with international and national standards, these transformers ensure superior quality, reliability, and performance. Customisable to meet specific project requirements, they offer a variety of sizes, temperature ratings, and mounting configurations.

Crafted with optimal magnetic topology, the Yawei S11-S13 series provides a robust solution for diverse electrical distribution needs, delivering power safely and efficiently across various applications.

GANELEC will assist with all specifications, sizing, pricing and lead times for your project. 

S11-S13 10-35kV Transformer Features:

1. Economical and environmentally friendly with excellent performance
   The S11-S13 series transformers deliver lower losses and currents compared to the S9 series, thanks to a continuously wound iron core with a circular cross-section. This design optimises the silicon steel sheet’s orientation, resulting in a no-load loss reduction of 20-45% and a no-load current decrease of 60-80%. The iron core remains naturally tight without clamps, ensuring stable and efficient operation.

2. Longer transformer lifespan
   The fully sealed fuel tank, secured via bolts or welding, prevents contact between insulating oil and air. This protective design slows the aging process of insulation, significantly extending the transformer's service life.

3. Low noise operation
   With a noise reduction of over 10 decibels, the seamless, compact core structure reduces operational noise by 7-10 dB. This makes the transformer ideal for installation in residential and building environments, ensuring quieter operation.

4. Reliable and secure operation
   Enhanced internal components and a secure sealing design improve overall reliability, ensuring safe and consistent performance.

5. Compact size with efficient cooling
   Utilising corrugated plate radiators, the S11 and S13 models adapt to temperature fluctuations by expanding and contracting, functioning effectively as oil conservators. This design allows for a smaller footprint without compromising cooling efficiency.
