    Application and construction

    Capacitors are intended for the improvement of Power Factor in low voltage power networks. Used MKP technology consists of metallized PP film with extremely low loss factor. The dielectric system is self-healing and has no liquid impregnant.

    The capacitors have overpressure protection to disconnect it from the supply in the event of internal failure and at the end of its operational life.

    The construction described above and the use of high quality materials ensure reliability and longevity.

    Working conditions:

     1.Power capacitor should confirm left voltage reduce to rated voltage 10% to input again after the power was cut off ,normally it will need 200s almost. so it would choose the power controller which has input and reput lock time function after cut off the power. If choose normally power controller, it must install speediness discharge power equipment .it would not limited which use adopting same electric factor input and chip switch.

    2. Altitude level is not more than 2000m.

    3. Temperature type: -25/C low temperature, highest temperature is C type (it would not more than 50 the average of temperature is not more than 40 within 24 hours, one year average of temperature is not more than 30 ),power capacitor will work within good ventilate condition. It would not permit within sealing and installation condition

    Feature:

    1. Low loss, good self-healing performance, low temperature rise, longer life;

    2. Adopted the most advanced manufacturing process, enhance dielectric resistance, lowest capacity loss, maintain excellent and stable electrical performance althought move in a long time;

    3. Heat dispersion is superior to other materials;

    4. Brass bolt terminal design in reason, avoid short-circuit, terminal lead connection is well;

    5. Leakproof structure, build-in security protector, a unique sequential protection system ensure safety of using;

    6. Build-in discharge resistor, voltage will drop below 50v within 3min after power off;

    7. Dry model
