As a premier supplier based in China, Keeya takes pride in offering high quality solutions, exemplified by their GGJ Low Voltage Reactive Power Compensation Cabinet. Engineered with precision and reliability in mind, these cabinets showcase Keeya's commitment to excellence in electrical power management.
As a trusted factory in the industry, Keeya's GGJ Low Voltage Reactive Power Compensation Cabinet provides efficient and precise solutions for enhancing power factor and optimizing energy efficiency in diverse applications.The GGJ series stands as a testament to the advanced technology and superior craftsmanship that characterize Keeya's products.
GGJ Low Voltage Reactive Power Compensation Cabinet is specially designed for the actual situation of the power grid. It adopts intelligent control technology, effectively solving the problem of automatic switching of reactive power compensation by parallel capacitors under harmonic conditions. On the other hand, it can filter out harmonics according to user actual requirements, clean the power grid environment, reduce losses, and eliminate harmonic hazards; And provide capacitor reactive power to the system to improve power factor. It can be used in power distribution systems in industries such as electricity, metallurgy, petrochemical, industrial and mining enterprises, construction, machinery, etc.
