Three Phase Power Capacitor
type low voltage shunt capacitor made of the advanced metallized film, is produced
strictly in accordance with the National Standard and IEC Standard by the introduced
advanced fore ign techniques and equipments. The device is mainly suitable for low
voltage power network to improve power factor, reduce reactive
loss and better the voltage quality.
The company depends on the superiority of science and technology and manages strictly in compliance with ISO9001, so the quality of the products are excellent but their prices are competitive and our services are all-round.
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
metallized polypropylene film.
2 Low loss: The real figure is lower than 0.10%, so the los s of the capacitor it self 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 equipped self-discharge resistor and safety equipment. The self-discharge resistor can automatically discharge the electric energy the capacitor carries. If there is anything fault with the capacitor, the safety equipment will cut off power in time,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-solid impregnant whose drip melting point it 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 dose not have to run the risk of invalidation caused by oil leakage.
