High-capacity DC support capacitor

Description
The windpower, solar power, HVDC is developing fast. So the power system faces the demand of diversity regulation. Required by time and tide, a great attention is devoted to power conversion, energy storage and transmission. Flair has been offering capacitors for power conversion, energy storage and power distribution and transmission. With our rich experience and strong RD team, we focus on providing with the most professional propoals and serving high-quality products failthfully and responsibly.

High voltage and high current working enviroment will accelerate the aging of capacitors that cause capacitor faulture easily. We studied on this project since 2017 when the national double carbon call is promoted. We have conquered key technology of large-capacity DC capacitor banks with satisfactory operation under harsh working enviroment.

DC support capacitor benefits

♢ High-voltage withstand ability: DC support capacitor is capable of supporting higher voltage more than normal capacitors. So it is suitable for dc power filter and high voltage dc transmission.

♢ Low loss: Its low loss feature make it is resultful to work as store and release electrical energy, as well as increase efficient and performance of the system.

♢ Long-lifespan: By applying for high-quality insulation material and stable dielectric, we make it’s reliable capacitance value and low ESR.

♢ Good frequency response: Even in high frequency ranged dc support capacitor performed good, keep its capacitance value stable and low ESR, such as power electronics, communication devices etc.
