- Fully sealed tank with high-quality insulating oil for optimal cooling
- Efficient heat dissipation reduces operating temperature
- Extends transformer lifespan and enhances operational safety
Ideal for residential areas, commercial centers, industrial parks, and rural electrification projects, the S13 series offers significant improvements over S9/S11 models:
- 20-30% lower no-load loss through premium silicon steel sheets and optimized magnetic circuit design
- Reduced load loss from improved winding structure and materials
- Improved temperature rise performance with better oil circulation
- Reduced noise levels through precision manufacturing
- Robust mechanical design for increased short-circuit resistance
- Extended service life (20-30 years) through superior materials
