1. Voltage & Connection Flexibility
High Voltage Options: 10kV / 6.3kV / 6kV
Tap Ranges: ±5% or ±2×2.5% for voltage regulation
Low Voltage: 0.4kV (standard distribution voltage)
Connection Groups: Yyn0 or Dyn11
2. Energy Efficiency
Ultra-Low No-Load Loss: Optimized core design minimizes standby energy consumption.
Low Load Loss: Efficient coil design reduces energy loss during full-load operation.
Low No-Load Current: Reduces reactive power consumption, improving power factor.
3. Impedance & Stability
Short-circuit impedance increases with capacity (4% → 4.5% → 5%), ensuring stable grid connection and short-circuit withstand capability.
