| Parameter Category | Parameter Name | Typical Values/Ranges | Additional Notes |
|---|---|---|---|
| Rated Capacity | Capacity Range | 30kVA ~ 2500kVA | Common specifications: 30, 50, 100, 200, 315, 400, 630, 800, 1000, 1250, 1600kVA |
| Typical Applications | - Small capacity (≤315kVA): Pole-mounted, small-scale distribution - Large capacity (≥630kVA): Industrial plants, buildings |
Select capacity based on load requirements to avoid overload or idle waste. | |
| Voltage Parameters | High-Voltage Side | 10kV | Tap range: ±5% or ±2×2.5% (voltage adjustment) |
| Low-Voltage Side | 0.4kV (3-phase 380V) | Some models support 0.69kV output. | |
| Connection Symbol | Dyn11 (common) or Yyn0 | Dyn11 offers better harmonic resistance. | |
| Loss Parameters | No-Load Loss (P | - 30kVA: ≈0.08kW - 1000kVA: ≈0.83kW |
S13 series reduces loss by 30%~37% compared to S11. |
| Load Loss (P, 75ºC) | - 30kVA: ≈0.63kW - 1000kVA: ≈10.3kW |
Copper loss caused by load current. | |
| No-Load Current (I%) | - 30kVA: ≈0.5% - 1000kVA: ≈0.17% |
Reactive power consumption during no-load operation. | |
| Short-Circuit Impedance | Nominal Value (Z%) | 4%~6% | - Small capacity (≤630kVA): 4% - Large capacity (≥1000kVA): 5%~6% |
| Cooling & Structure | Cooling Method | ONAN (natural oil circulation) | No forced cooling equipment, low maintenance cost. |
| Tank Design | Sealed corrugated tank (e.g., S11-M, S13 series) | Leak-proof, anti-oxidation, extended lifespan. | |
| Insulation Class | Class A (105ºC thermal resistance) | Mineral oil and cellulose composite insulation. | |
| Environmental Adaptability | Operating Temperature Range | -25ºC ~ +40ºC | Maximum daily average temperature ≤30ºC. |
| Altitude Limit | ≤1000 meters | High-altitude areas require derating or special design. | |
| Noise Level | Sound Power Level | S11 series: ≤50dB S13 series: ≤45dB |
Ultra-low loss design reduces noise. |
| Model Comparison | S11 Series | S13 Series | |
| - Standard energy-saving type | - Ultra-low loss type | ||
| - Baseline no-load loss | - 37% lower no-load loss than S11 | ||
| - Noise ≤50dB | - Noise ≤45dB |
