The capacitors are developed on our own by adopting advanced technology at home and abroad, and they are mainly used in the starting and running of single-phase asynchronous motors with 50Hz or 60Hz. And they have distinctive self-healing ability because of using modern metalized polypropylene film as dielectric. The series of products is classified as CBB60, CBB61 and CBB65 three types according to the difference of outline size, product structure and capacitances. This product is suitable for frequency 50Hz (60Hz) AC single-phase motor power supply start-up and operation, widely used in electric fans, washing machines, refrigerators, electric pumps and other equipment.
