Self-Healing Shunt Power Capacitor

BSMJ self-healing shunt power capacitor

Our self-healing type low voltage shunt capacitor, applied the advanced Zn-Al complexed metellized film, adopted forein gadvanced production techology techniques and international IEC60831-1(1996) standards. The products is mainly suitable for low voltage electric network to improve power factor, reduce reactive loss, and improve the voltage quality.
