| High Light | 500kVA 800kVA Compact Substation ，11kV 0.4kV Prefabricated Substation ，EV Charging Compact Substation | ||
The High Efficiency Step Down Electric EV Charging Compact Substation (500kVA–800kVA, 11kV to 0.4kV) is an all-in-one prefabricated power distribution solution specifically engineered for public EV charging hubs, commercial fleets, and rapid-charging infrastructure. Integrating high-voltage switchgear, a low-loss oil-immersed distribution transformer, and an intelligent low-voltage distribution cabinet within a heavy-duty, weather-resistant enclosure, this compact substation steps down medium voltage (11kV) to low voltage (0.4kV/0.415kV) safely and continuously. Built to handle frequent load surges, continuous high-power output, and extreme outdoor environments, it provides turnkey reliability for urban public charging hubs and highway infrastructure.
| African Desert & High-Dust Challenges | Engineering Solutions & Design Features |
|---|---|
| Heavy Sandstorm & Fine Dust Ingress | Double-sealed cabinet doors equipped with labyrinth-type dust filters, sand-proof ventilation louvers, and IP54/IP55 dustproof enclosure integrity. |
| Thermal Degradation of Oil Gaskets | High-grade fluororubber (FKM) gaskets and synthetic O-rings replaced standard rubber, preventing gasket drying, hardening, and oil seepage under 50°C+ ambient temperatures. |
| Oil Oxidation & Leakage Risks | Hermetically sealed corrugated tank design with zero air contact eliminates oil sludge formation, pressure build-up, and seal degradation. |
| Extreme Sunlight & UV Corrosion | Multi-layer C4/C5 grade anti-corrosion marine paint with UV-reflective topcoat to lower internal cabinet temperature and prevent casing rust. |
A: The substation features a double-layer insulated cabinet, temperature-controlled forced air cooling, and high-thermal-class ONAN transformer oil, ensuring continuous full-load output up to 50°C ambient without derating.
A: We utilize hermetically sealed corrugated oil tanks, 100% vacuum oil filling, and anti-aging fluororubber gaskets. Every unit undergoes a 24-hour factory pressure leak test before shipment to guarantee zero leakage.
A: Yes. We customize low-voltage switchgear, copper busbar capacity, circuit breaker quantities, and smart metering according to your EV charger quantities and power ratings (e.g., 60kW to 360kW chargers).
A: Absolutely. The complete substation complies fully with IEC 62271-202 (high-voltage/low-voltage prefabricated substations) and IEC 60076 (power transformers), complete with type test and routine test reports.
A: Standard manufacturing takes 25–35 days. We offer a comprehensive 24-month quality warranty, wearing parts kits, and remote technical guidance for installation and commissioning.
A: The integrated unit is mounted on a heavy-duty steel skidbase, packed in ocean-worthy wooden crates with moisture-proof wrapping, and sized to fit standard 20ft/40ft HQ shipping containers.
