S11 Series 1250kVA / 1600kVA High-Efficiency Oil-Immersed Step-Up Transformer. Our S11 series step-up transformers are specifically engineered for the rigorous demands of renewable energy grid connections. Whether for utility-scale solar farms or wind power projects, these units provide a stable 10kV to 15kV output. Built with premium materials, they ensure high conductivity and minimal core loss, making them the preferred choice for EPC contractors seeking reliable power evacuation in harsh environments.
- Optimized for Renewables: Seamlessly bridges the gap between low-voltage power generation and medium-voltage grids (10kV-15kV)
- High Efficiency & Low Loss: The S11 wound-core design significantly reduces no-load losses and noise levels compared to older models
- Extreme Weather Resilience: Specially treated for high-temperature and high-dust environments typical of African and Middle Eastern regions
- Superior Load Capability: Robust thermal design allows for continuous operation under fluctuating power inputs from solar/wind sources
| Core Design | Utilizes high-quality, cold-rolled grain-oriented (CRGO) silicon steel with a multi-step lap joint to minimize magnetic resistance |
|---|---|
| Winding Material | High-purity electrolytic copper (or aluminum upon request) with multi-layer insulation to withstand voltage surges and harmonic distortion |
| Cooling System | Natural Oil Convection (ONAN) with reinforced radiator fins for enhanced heat dissipation in ambient temperatures up to 50°C |
| Insulation Class | Level A insulation with high-flashpoint mineral oil to ensure long-term dielectric stability |
| Tap Changer | Off-circuit tap changer (OCTC) with ±2*2.5% range to maintain a stable output voltage despite grid fluctuations |
In many African regions, fine sand and extreme dust often lead to seal degradation and cooling obstructions. We address these operational challenges with targeted engineering:
