Flexible HVDC DC-Link Support Capacitor
Description
With persistent invest in developing and researching, the flair HVDC DC-link support capacitor is widely used in power grid, such as 66KV Grid type direct-mounted static VAR generator, 220Kvar offshore windpower transmission，800Kvar HVDC power transmission, 800Kvar HVDC substation etc; For high voltage direct current transmission project, we keep on innovating and pave a distinctive way of flair style. We take “high-quality, technology-thrive, brand-credibility” as our aim, offering accurate solution, perfect service and product at our best.
Conform to the trend of the times, the green energy is demanding. Since the DC-link support capacitor is core components for HVDC converter valves. We will do our best to contribute to facilitate efforts to meet global power demand with clean and green alternatives.
