WSC-IX a new generation of stainless steel, titanium gold box type intelligent integrated low voltage filter capacitor of Wisconsin Wenzhou Industrial Co., Ltd. in twenty years of professional manufacturing on the basis of the lowvoltage power capacitor after years of exploration and practice, the research and development of a new generation of free products of reactive power compensation. The intelligent compensation unit consists of a liquid crystal display interface, an intelligent control unit, a zero crossing switching unit, a protection unit, a filter reactor and a low voltage filter power capacitor. The pipeline type electric power capacitor, using aerodynamics principle of heat conduction, through a pipeline to form a cold and hot air convection, accelerate the release of internal capacitance of high calorie, great to meet all kinds of application environment needs. This product is suitable for the occasions with large harmonic pollution, reliable operation, will not produce resonance, no amplification of harmonics, and to a certain extent, there is an absorption to eliminate the harmonic function. The series connected 7% reactor products used in the 5 (and more than 5 times) harmonic based electrical environment, series connected to the 14% reactor products used in 3 (and more than 3 times) harmonic based electrical environment.
