Features & Advantages
1. Low loss, low noise and high reliability.
2. Excellent dynamic thermal stability and high over-load capacity.
3. Simulation analysis was carried out for the core mould design, thus to greatly reduce noise level. Simulated lightning impulse wave process was carried out for HV winding mould design, thus to greatly improve product's anti-lightning impulse capability.
