Product features

RUC capacitors belong to cylindrical, self-healing, and kilowatt type capacitors, mainly used to improve power factor and power quality. They are divided into single-phase and three-phase according to different occasions.


RUC capacitors are manufactured in an environment with a purification level of 100, and the components are heated and filled under 10 Bar vacuum conditions. This method can allow air and moisture to be discharged from the inside of the capacitor, thereby avoiding electrode oxidation and local discharge. After this complex process and strict factory inspection and quality evaluation, the capacitor is guaranteed to have excellent stability and long-term service life.








Design and characteristics of parallel capacitors



Microwave pattern edge cutting technology


The RUC capacitor adopts a thickened (8 μ m/9 μ m) self-healing metallization film coated with special metal components. By adopting a special corrugated edge cutting design, the effective metal spraying area on the side of the component winding is increased by 20%, which greatly strengthens the component and its additional connection points, playing an important role in resisting large currents and ensuring the stability of the capacitor.


self-healing


When the capacitor experiences overvoltage, overcurrent, or near its service life, it is highly likely to experience breakdown, and the metallized layer can be broken down and evaporated within a few microseconds. At this point, an insulation area without a metallized layer will be formed in the breakdown area (this area will not participate in the charging and discharging process when it exits work). After breakdown occurs, the capacitor can function normally. Due to self-healing, the capacity loss caused by self-healing is less than 100PF. By using high-quality metallized films, the self-healing density of the product can reach over 70%.


Strict inspection requirements


RUC capacitors comply with 100% component testing standards, and all components undergo strict quality testing before capacitor assembly to ensure the electrical performance and safe service life of the capacitor:

1、Winding detection
2、Loss detection
3、Self healing testing
4、High temperature tolerance testing
5、Capacitance tolerance detection
6、Voltage withstand test
