Standard 400/500 kVA 11 kV to 0.433 kV Power Distribution Transformer for Airport Terminal Expansion Projects
Product Overview
The Standard 400kVA/500kVA 11kV to 0.433kV Power Distribution Transformer is a high-specification dry-type solution engineered for mission-critical infrastructure like airport terminals and transport hubs. Utilizing advanced SCB13 cast resin technology, this transformer ensures stable power delivery for airfield lighting, HVAC systems, and terminal electronics. Designed to meet IEC 60076-11 global standards, it provides the ultimate combination of fire safety, energy efficiency, and environmental protection for large-scale urban development projects.
Key Features
Aviation-Grade Reliability: Engineered for 24/7 continuous operation, ensuring zero downtime for critical airport infrastructure and terminal services.
Superior Fire Safety & Self-Extinguishing: The epoxy resin solid insulation is flame-retardant and moisture-proof, eliminating the risk of fire or toxic gas emission in crowded public spaces.
High Overload Resilience: Equipped with an intelligent forced-air cooling (AF) system, allowing the unit to handle peak passenger traffic loads without compromising service life.
Low Harmonic Disturbance: Optimized core design reduces electromagnetic interference, protecting sensitive airport navigation and communication systems.
Eco-Friendly & Maintenance-Free: No oil, no leakage, and low noise. This design minimizes operational costs and simplifies environmental compliance for green airport projects.
Technical Specifications
Rated Capacity: 400 kVA / 500 kVA
Voltage Ratio: 11kV Primary / 0.433kV Secondary (Ideal for overcoming voltage drops in large terminals)
Insulation System: Vacuum Pressure Casting (VPC) with high-grade epoxy resin, Rated Class F (155°C) or Class H (180°C)
Core Technology: 3-phase 3-limb core made of high-permeability, grain-oriented silicon steel with a multi-step lap joint to minimize losses
Noise Control: Specialized damping structures reduce vibration to ≤45-50 dB, ensuring a quiet environment for passengers
Protection Class: Standard IP20, with customizable IP23 or IP31 enclosures for enhanced safety against accidental contact
Monitoring: Integrated PT100 sensors and digital temperature controller with RS485 for remote SCADA integration
Regional Solutions
Challenge: Severe Dust Accumulation in Arid Regions
In many African airport locations, fine sand can clog traditional cooling ducts, leading to overheating.
Our Solution
Our transformers feature Vertical Smooth-Surface Cooling Channels. The high-gloss finish of the cast resin prevents dust from adhering. Combined with an optimized airflow design, the unit effectively "sheds" particles, maintaining thermal efficiency in sandy environments.
Challenge: Oil Seepage & Soil Contamination
Traditional oil-immersed units face seal degradation in extreme heat, creating environmental hazards and fire risks.
Our Solution
Our Solid-Cast Dry Design completely removes liquid dielectrics. With zero oil usage, there is absolutely no risk of leakage, seepage, or soil contamination. This eliminates the need for oil sumps and complex firefighting systems, drastically reducing civil engineering costs for airport developers.
Frequently Asked Questions
Q: Can this transformer support the heavy startup currents of airport HVAC systems?
A: Yes. The 400/500kVA units are designed with high mechanical strength and thermal capacity to handle the inrush currents of large central air conditioning compressors.
Q: Does it comply with African national grid standards?
A: Absolutely. Our transformers strictly follow IEC 60076, which is the recognized standard for most EPC projects across Africa, including Nigeria, Kenya, and Ethiopia.
Q: How do you support EPC firms during the bidding stage?
A: We provide a full technical packet, including Type Test Reports, 3D CAD drawings, and energy efficiency certifications to strengthen your tender.
Q: What is the maintenance requirement for a busy terminal substation?
A: It is virtually maintenance-free. We only recommend a visual inspection and light cleaning of the air ducts every 12 months to ensure optimal airflow.
Q: Is the voltage adjustable if the 11kV grid fluctuates?
A: Yes. The unit includes ±2x2.5% off-circuit tap changers, allowing you to fine-tune the output to a stable 433V regardless of grid conditions.
Q: How is the product protected during long-distance sea freight?
A: We use reinforced, seaworthy wooden crates with vacuum moisture-barrier packaging to ensure the unit arrives at the airport site in perfect condition.
