Robust Construction 20kV 400V 400kVA 500kVA Electrical Distribution Unit Easy Install for Data Centers OEM
Product Overview
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.
Core Selling Points
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.
Detailed Technical Specifications
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
Solution for High-Dust & Sandy Environments
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.
FAQs for African Distributors & EPC Projects
Q1: Can you provide customized branding (OEM) for our local engineering brand?
A1: Certainly. We support full OEM services, including custom nameplates, color specifications (RAL codes), and technical documentation branded with your company info.
Q2: How does this transformer perform in the 45°C+ ambient temperatures common in Africa?
A2: Our 500kVA units are designed with a 55/65°C temperature rise limit, utilizing premium insulating oil with high flashpoints to ensure stable operation in extreme heat.
Q3: Is this unit compatible with the specific 20kV grid requirements in my country?
A3: Yes, we can adjust the tapping range (e.g., ±2x2.5%) to ensure the transformer perfectly matches your local grid voltage fluctuations.
Q4: What is the protection level against sand and salt-mist corrosion?
A4: We use a C4-class anti-corrosion coating system, involving multi-layer electrostatic spraying that prevents sand-blasting erosion and rust.
Q5: What is the lead time for a standard EPC project requiring 10-20 units?
A5: Our specialized production line for 400kVA-500kVA units ensures a fast turnaround of 20-30 days from order confirmation to port delivery.
Q6: Do you provide on-site installation guidance for data center setups?
A6: We provide comprehensive video tutorials and 24/7 remote engineering support to ensure your "Easy Install" process is seamless.
