multicab-F fixed capacitors

KBR multicab-F fixed capacitors compensate the inductive reactive power

multicab-F fixed capacitors

multicab-F fixed capacitors compensate the inductive reactive power directly at the place it occurs, which relieves the supply lines considerably. Fixed capacitors are used for consumers with relatively large power, such as transformers and motors.
