Characteristics: With polypropylene film of excellent eletric performance as medium, the actual loss rate is below 0.2%, with the advantages such as lttle heating, low temperature rise, long service life and good self-cure function. Each technical index reaches national standard GB/T12747/IEC60831, with international advanced level. When there is a failure in the capacitor, it can automatically cut off the power, to avoid explosion and fire, and make the operation safe and reliable. After cutting off the power of the capacitor, it can make the electrode voltage of the capacitor decline below 50V.
