GMKPbw Dynamic Capacitor Bank

The GMKPbw series is a automatic dynamic real-time control, three-phase and single-phase mixed compensation capacitor bank, are especially designed to compensate the reactive energy in dynamic power networks outdoor for the normal load or with  harmonics content, permitting not only the correction of the fluctuation caused by lineal, but also the non-lineal electrical loads.


●Pole/outdoor or wall mounting

●Static/Thyristor/Transistor or normal contactor switching

●More than thousand sets are using in the China National Power Grid

●Stainless steel case of IP54

●Automatic data transmission by RS483/232,GPS,GPRS etc

●Double compensation for 3phase & single phase  

●Special for power utility (capital management are available)
