Our 2000kVA 11kV/0.433kV step-down transformer is a high-performance solution designed for reliable urban power distribution and industrial grid stability. Compliant with IEC 60076 standards, this S11 series oil-immersed transformer is engineered to bridge the gap between high-voltage transmission and localized power needs, ensuring consistent energy flow for manufacturing plants, commercial complexes, and infrastructure developments.
- Maximized Energy Efficiency: Features an advanced silicon steel core that significantly reduces no-load losses and operational costs
- 100% Electrolytic Copper Windings: Ensures superior thermal stability and electrical conductivity, preventing overheating during peak load hours
- Climate-Resilient Construction: Specifically treated with high-grade anti-corrosion coatings to withstand high humidity and extreme tropical temperatures
- Zero-Maintenance Sealing: The hermetically sealed tank design prevents oil oxidation, extending the service life to over 30 years without the need for periodic oil filtration
| Core Technology | High-permeability, grain-oriented cold-rolled silicon steel with 45-degree full-miter joint to reduce magnetic noise and vibration |
|---|---|
| Cooling System | ONAN (Oil Natural Air Natural) cooling with high-surface-area corrugated radiators for rapid heat dissipation |
| Insulation Class | Class A insulation with high-dielectric strength transformer oil, tested for breakdown voltages exceeding 50kV |
| Vector Group | Dyn11 (ideal for unbalanced industrial loads) or Yzn11 per project requirements |
| Protection Devices | Integrated pressure relief valves, oil level gauges, and multi-functional signal thermometers for real-time monitoring |
In sand-prone regions like Africa, airborne particles and extreme heat often lead to seal degradation. We solve these environmental challenges through:
- Double-Gasketed Sealing Technology: High-performance nitrile rubber gaskets and precision-machined flange surfaces create a "Dual-Barrier" against fine dust infiltration and prevent oil seepage
- Vacuum-Oiling Process: Removes all air bubbles and moisture during filling, eliminating internal pressure fluctuations that cause micro-cracks in traditional seals
- Reinforced Corrugated Tanks: Robotically welded and pressure-tested to 0.5 bar, ensuring structural integrity under heavy sandstorms and thermal expansion cycles
Yes, our units are fully compliant with IEC 60076 and come with comprehensive Type Test Reports from accredited laboratories.
We use heavy-duty seaworthy packaging and reinforced steel frames to ensure the transformer arrives without mechanical vibration damage.
Absolutely. We offer customizable tap changers (±2x2.5% or ±5%) to match specific local grid demands.
For a standard 2000kVA unit, our production cycle is 15-20 days, supported by a massive inventory of raw materials for rapid scaling.
We offer high-creepage distance porcelain or composite bushings that prevent flashover in dusty and sandy environments.
