This product uses thickened metalized polypropylene film as a dielectric, coiled by high speed winding machine, encapsulated with Aluminum body. It is treated by using refined castor oil as impregnant in the high temperature and vacuum environment to make the capacitor more stable with long working life. Mean while based on the principle of safety and proof-explosion,this kind of capacitor has been used the second generation mechanical explosion proof design to strengthen the reliability.

The function of the refrigerator capacitor:
The capacitor is auxiliaryly started at low voltage. When the compressor starts, the resistance is small, the starting winding works, and the press rotates. When the speed is reached, the heat resistance of the starter becomes larger, the starting winding is disconnected, and the winding is operated. PTC starter, positive temperature coefficient thermistor. The resistance value at room temperature is very small (about a few ohms), and the compressor is connected in series with the capacitor to start the winding. When the power is turned on (after the compressor is started), the resistance increases rapidly (up to several hundred kilohms).
