Low-Voltage Power Capacitor
The low-voltage power capacitor is designed for low-voltage AC systems and is mainly used for reactive power compensation and filtering applications. Its purpose is to improve power factor, reduce line losses, enhance power quality, and minimize electrical losses in the system. With low impedance, low loss, compact size, and excellent heat dissipation, it is suitable for power quality improvement systems requiring stable and reliable capacitor performance.
