Key Safety & Performance Features

1. Self-healing technology
    
   Minor dielectric breakdown automatically repairs, avoids capacitor short-circuit failure.
2. Overpressure disconnector safety device
    
   Internal pressure rise triggers mechanical disconnection to isolate fault and prevent explosion risk.
3. Built-in discharge resistors
    
   Quickly release residual voltage after power-off for maintenance safety.
4. Heavy-duty anti-harmonic design
    
   Enhanced current carrying capacity, matches detuned reactor APFC panels with high harmonic loads.
5. Low heat loss, stable long-term operation
    
   Low dielectric loss reduces cabinet temperature rise, extending whole compensation cabinet service life.
