1. Compacted and light: Its volume and weight are only 1/4 and 1/5 of the old product because of the using of a new dielectric-mtallized polypropylene film.
2. Low loss: The real figure is lower than 0. 10%, so the loss of the capacitor itself is extremely low, the heat it gives out is little and the rise of temperature is low. So its service life is very long and it can save energy at the same time.
3. Excellent self-healing ability: Damage of part of the dielectric caused by over-voltage can be self-healed quickly and return to normal state. So the reliability is much higher.
4. Safety: Inwardly eaquipped self-discharge resistor and safety equipment. The self-discharge risistor can automatically discharge the electric energy the capacitor carried. If there is anything fault with the capacitor, thus prevent further troubles from happening. So it's much safer to use this kind of capacitor.
5. No oil leakage: The capacitor uses advanced semi-soild impregnant whose drip melting point is above 70. There will be no loss of oil during the course of using it. And thus protect the surroundings from being polluted. The capacitor itself doesn't have to run the risk of invalidation caused by oil leakage.
