The S11 series oil-immersed step-up transformer is engineered specifically for the rigorous demands of hydroelectric power generation. Available in 1250kVA and 1600kVA capacities, this unit features premium 100% copper winding design to ensure maximum electrical conductivity and mechanical strength. It efficiently elevates generated voltage (10kV-15kV) for long-distance grid transmission, offering a robust, low-loss solution for renewable energy developers and EPC contractors globally.
- 100% Pure Copper Windings: Ensures superior thermal stability, higher short-circuit resistance, and significantly lower energy dissipation compared to aluminum alternatives.
- Optimized for Hydro-Generation: Designed to handle continuous duty cycles and load fluctuations typical of small to medium-scale hydropower stations.
- S11 Ultra-Low Loss Core: Utilizes high-permeability cold-rolled silicon steel, reducing no-load losses and improving overall Energy Efficiency Ratio (EER).
- C5-M Corrosion Resistance: Finished with high-durability coating systems to withstand high-humidity environments near water sources.
- Modular Customization: Flexible voltage ratios and bushing configurations to meet various international grid standards.
| Core Technology | Stacked multi-step lap joints to minimize noise and magnetic flux leakage |
|---|---|
| Insulation System | Class A insulation with high-dielectric mineral oil, providing exceptional cooling and arc suppression |
| Winding Technique | Circular-concentric winding structure with high-density pressboard spacers for enhanced mechanical rigidity |
| Cooling Method | ONAN (Oil Natural Air Natural) with precision-engineered corrugated radiator fins |
| Protection Level | Fully sealed hermetic design to prevent oil oxidation and moisture ingress |
Environmental Challenge: In African regions with heavy dust and sandstorms, traditional seals often fail, leading to oil contamination and leakage, which causes equipment downtime.
Our Engineering Solution:
- Double-Seal Bushing System: High-grade silicone rubber gaskets and specialized dust-proof covers prevent fine sand from eroding seals
- Reinforced Corrugated Tank: Robotically welded with reinforced seams to ensure zero-leakage under extreme thermal expansion
- Stainless Steel Hardware: All external fasteners made of 304/316 stainless steel to prevent rust in high-salinity environments
