Characteristics:

• Small size, lightweight, easy to install

Using high-quality high-temperature resistant metallized polypropylene film new material as the medium, the unique structural design makes the capacitor volume and weight only 1/4 and 1/4 of the old product.

• Low loss, less heat, low temperature rise

Using a new gold spraying process and a unique metallized film edge thickening technology, the capacitor’s ability to withstand inrush current is enhanced, its performance is stable, its working life is extended, and the energy consumption of the capacitor itself is reduced.

• Excellent self-healing performance medium

Local breakdown can heal itself quickly.

• New explosion-proof design, safe and reliable

Built-in self-discharge resistor and new-patented explosion-proof device, safe and reliable to use.

• Dry structure, no oil leakage, safe and environmentally friendly

It is made of microcrystalline wax, which is solid at room temperature and has a melting point higher than 70°C. It can be impregnated under high vacuum.

• Corrosion-resistant and anti-counterfeiting metal shell, beautiful and sturdy

The metal shell has undergone special double anti-corrosion treatment to improve corrosion resistance.

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 repute 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.
