The 400kVA 500kVA 20kV to 400V Oil Immersed Distribution Transformer is a high-performance Electrical Distribution Unit specifically engineered for high-density power environments like Data Centers and Industrial Manufacturing. This Robust Construction unit is optimized for OEM services, providing a stable 0.4kV output from a 20kV high-voltage grid. Designed with an emphasis on Easy Installation and long-term reliability, it ensures uninterruptible power supply for sensitive IT infrastructure and heavy-duty machinery.
- Engineered for Data Centers: Features high harmonic endurance and ultra-stable voltage regulation, ensuring clean power for servers and precision cooling systems.
- Rapid OEM & ODM Customization: We offer flexible design options for terminal locations, tank dimensions, and monitoring accessories to fit specific project layouts.
- Superior Thermal Efficiency: Utilizing high-grade mineral oil and an optimized convection design to maintain safe operating temperatures even under continuous 100% load.
- Reinforced Structural Integrity: The heavy-duty steel tank and anti-vibration core clamping system are built to withstand harsh shipping conditions and rugged site environments.
- High-Purity Copper Winding: 100% oxygen-free copper ensures the lowest electrical resistance, minimizing energy waste and heat generation.
- Rated Power: 400kVA / 500kVA Three-Phase
- Voltage Configuration: 20kV Primary (High Voltage) to 0.4kV/400V Secondary (Low Voltage)
- Frequency: 50Hz / 60Hz compatible for global grid synchronization
- Core Material: High-permeability, cold-rolled grain-oriented (CRGO) silicon steel for reduced no-load loss and whisper-quiet operation
- Cooling System: ONAN (Oil Natural Air Natural) with expanded surface area corrugated fins for maximum heat exchange
- Insulation Level: LI 125kV / AC 50kV (High-standard dielectric strength)
- Standard Compliance: Fully manufactured and tested according to IEC60076 and IEEE standards
In many African regions, extreme sandstorms and fine dust pose a significant challenge to equipment airtightness. Dust buildup on traditional seals often leads to brittleness and subsequent leakage.
The Issue: Sand abrasion and dust accumulation act as a desiccant, drawing oil out of standard gaskets and leading to system failure.
Our Engineering Solution: We implement a Triple-Barrier Sealing System. This includes Aviation-Grade Nitrile Gaskets protected by a secondary Dust-Shield Cover.
Leakage Prevention: Every unit undergoes a 48-hour High-Pressure Leak Test and vacuum oil filling. The fully-welded corrugated tank eliminates the need for a conservator in this range, creating a hermetically sealed environment that keeps sand out and oil in, ensuring zero-leakage performance for decades.
