SFR-L Capacitor Bank

SFR-L series LV(low voltage) power capacitor module is designed for 0.4kV low voltage distribution power distribution system. It is used as a new generation of compensation module with functions of energy saving, reduction of line loss, power factor enhancement and improvement of power quality. This module is mainly used in the occasions where the harmonic distortion is not that serious. SFR-L series low voltage power capacitor modules take two type compensation capacitors or one Y type compensation capacitor as main body and are highly integrated with compound switch, microprocessor and other function modules.
