Let us first assume that there are two electrode plates placed parallel to A and B. The gap between them is made of insulating material such as air. Then a switch S is connected to the DC source E in the middle...

The safety protection performance of the CBB capacitor, after the capacitor is charged, the power supply is closed, and the charge in the CBB capacitor can still be stored for a long time. This charge is sufficient to cause electric shock or damage the connected equipment...

CBB capacitors use a metal foil as an electrode, which is overlapped with polypropylene film from both ends and wound into a cylindrical structure. The principle is the same as that of polyester capacitors...

Metal film CBB capacitors have high reliability and self-healing. As long as the circuit design is reasonable and the specifications are selected correctly, the capacitor is not easily damaged...

When the motor starts, a starting capacitor with a larger capacitance is disconnected from the circuit under the action of the centrifugal switch to complete its task, leaving the running capacitor still connected in series in the starting winding of the motor to work...

When the single-phase motor is working, it will involve the problems of starting capacitor and running capacitor. Because single-phase electricity is different from three-phase electricity, a single-phase motor cannot form a rotating magnetic field when it is started, and uses the characteristic of the current in the capacitor to generate a rotating magnetic field to start the motor...

CBB capacitors are polypropylene film capacitors and have no polarity. There is no need to distinguish between positive and negative poles. Among the common types of capacitors, only electrolytic capacitors need to distinguish between positive and negative poles...

A metallized film capacitor is a metallized film capacitor composed of a double-sided metallized polypropylene film and a non-metallized polypropylene film that are rolled or laminated.

The film capacitor has many excellent characteristics, so it is an excellent capacitor...
