GMKPBFM Medium Voltage Power Capacitors

GMKPBFM series medium voltage power capacitor in a steel can was designed for Power Factor Correction (PFC) in AC low voltage power system. The GMKPBFM capacitor unit is available in the range from 25 to 800kvar up to 24/36KV, loads like motors, power transformers, power line, as well as reactive power, the benefits of PFC are saving energy and reduce carbon dioxide emission. Our long year know how of GMKP capacitor technologies included Gas TechnologySpecial protection fuse, and Special design & process etc.


●Long life cycle (200,000 hours) ●Highest pulse current withstand capability     ●Corona-free 
●Very low losses   ●Internal fuse protection                             ●Terminal forhigh capacity cables with steel assistant
