Power capacitors are capacitors used in power systems and electrical equipment. Connected in series with power frequency high-voltage transmission and distribution lines, used to compensate for the distributed inductance of the lines, improve the static and dynamic stability of the system, and enhance the voltage quality of the lines Extend the power transmission distance and increase the transmission capacity. Self healing low-voltage parallel capacitors are made of metalized film, imported foreign technology and equipment, and produced strictly in accordance with standards and IEC standards. They are mainly used in low-voltage power grids to improve power factor, reduce reactive power loss, and improve voltage quality.
