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.
- 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.
- 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
In many African airport locations, fine sand can clog traditional cooling ducts, leading to overheating.
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.
Traditional oil-immersed units face seal degradation in extreme heat, creating environmental hazards and fire risks.
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.
