Low voltage components

KD-H dry environment-friendly capacitor adopts advanced German technology and is manufactured in an environment with a hundred level purification level. The element is heated under 10-3 Bar vacuum condition and the protective gas is injected at the same time. In this way, air and moisture can be discharged from the capacitor, thus avoiding electrode oxidation and partial discharge. Through this complex process and strict factory inspection and quality evaluation, it is ensured that the capacitor has excellent stability and long service life. It can be divided into single-phase and three-phase according to different occasions.

Low voltage power capacitor

Original imported capacitor

MOKN series capacitors imported from Germany are very popular in the Chinese market because of their unique technology. Nitrogen (N2) filling, special SINECUT slotting technology and unique metal processing technology, as well as the most reasonable inner core position, are used in the production process of capacitors to ensure that the capacitance of equipment remains unchanged under the impact of large AC high-voltage negative pressure. This unique feature of MOKN series products makes it particularly suitable for applications in controlling equivalent DC current and surge.
