DC filter capacitor  

This kind of capacitor takes metalized safe film, unique squashing and welding process, advanced shockproof and voltage sharing and current sharing innovate internal structure of the capacitors etc technology ensure the stability and accuracy of the capacitance, low inductance and significantly enhance the strength of the resistance to high voltage and surge. This kind of capacitor can be designed dry fire-retardant structure and the structure of high-quality oil impregnated under the environment of the high vacuum macerate, which improve the insulation and the stability of capacitance, longtime and reliability, and possess good radiation, which ensure the capacitor operate for a long time.

Application Fields  DC filter capacitor(Traction power capacitor)is widely used in: AC Electric locomotives, metro and light rail transit locomotives support capacitor in the DC loop of the AC drive system, metro and light rail transit locomotives braking energy saving system, storage and starting capacitor for large wind power system and solar power system AC support capacitor  kinds of high-power AC-DC-DC inverter system and the smoothing filter capacitors in the output circuit, high voltage DC transmission (HVDC), Static Var Compensator(SVC) filter compensation capacitors, the variable-frequency for transmission equipment of pumps, large fans and electric transmission corridor in the field of chemicals, textiles, machinery, iron and steel industry .
