- Product Introduction
Genuine Power's low voltage self-healing power capacitor is designed to enhance the power factor of AC power systems with a rated voltage of 1 kilovolt or lower and a frequency of 50 hertz or 60 hertz.
Our product features a metallized plate with self-healing properties, which can achieve insulation recovery within microseconds when insulation is broken down. It is suitable for reactive power compensation, harmonic filtering, and improving power quality.
