Reliable Structural Design
- Spiral windings with longitudinal oil channels for enhanced internal heat dissipation.
- Reinforced support at winding ends for increased short-circuit resistance.
- New lifting and positioning structures ensure safe long-distance transport and stable operation.
- Multiple proprietary structural designs deliver higher reliability and performance.
- Advanced engineering ensures superior technological performance across all models.
Premium Material Selection
- Oxygen-free copper wire with low resistivity and smooth, burr-free surface treatment reduces load loss and improves electrical reliability.
- High-quality silicon steel sheets with low unit loss minimize no-load loss.
- Laminated wood insulation components remain intact even under short-circuit conditions.
- Deep-filtered transformer oil with minimal water, gás, and impurity content.
- Durable rubber seals effectively prevent aging and oil leakage.
- All materials undergo strict quality inspection and supplier audits in compliance with ISO9001 standards.
- Compared to the S9 series, the S11 series offers:
- 30% reduction in average no-load loss
- 70–85% lower no-load current
- 10K lower average temperature rise
- Over double the service life
- Capable of continuous 20% overload operation
- 2–4 dB lower operating noise

- The “M” in model S11(M)R denotes a fully sealed tank design.
- Replaces conventional oil pipes with corrugated fins for heat dissipation, eliminating the need for an external oil conservator.
- Welded corrugated fins, made from high-quality cold-rolled steel, allow oil volume expansion while isolating the interior from the atmosphere.
- This design slows oil aging and prevents moisture absorption, ensuring maintenance-free operation.
- The tank undergoes degreasing, derusting, phosphating, and triple-protection coating, making it suitable for harsh environments such as metallurgical, peitriceimiceach, and mining applications.
