▶ See How Xinchangda Solves It| Parameter | Typical Range | Unit | Notes |
|---|---|---|---|
| Rated Power (kVA) | 5 – 10 000 | kVA | Customizable per load study |
| Primary Voltage | 380 – 11 kV | V | Three‑phase delta or wye |
| Secondary Voltage | 380 – 0.4 kV | V | Multiple taps available |
| Frequency | 50 / 60 | Hz | Dual‑frequency models on request |
| Efficiency | ≥ 98.5 % | % | Meets IEC 60076‑2 |
| Temperature Rise | ≤ 55 °C | °C | Tested under IEC‑Load‑Curve |
Case 1 – Solar Inverter Farm (USA): 2 MW plant required 3‑phase 500 kVA transformers. Xinchangda delivered a custom‑designed unit with 12 % lower loss, cutting annual energy cost by $45 k.
Case 2 – Medical Imaging Facility (Germany): Precise harmonic mitigation demanded a 250 kVA unit with IEC‑61850 communication. On‑time delivery avoided a 3‑month project delay.
Case 3 – Automotive Assembly Line (Mexico): High‑inrush motors required a 1 MVA transformer with reinforced windings. Production uptime rose to 99.7 % after installation.
