Main Characteristics
1.Small volume and light weight
It is only 1/4 and 1/5 of the weight and the volume of the outdated products respectively.
2.Low loss
With the actual loss less than 0.1%,the capacitor,itself,has low consumption of energy,little radiation,low temperature rise,long service life,and good energy conservation effect.
3.Excellent self-healing performance
When a part of the isolation is fed through due to the overvoltage,it is capable of self-healing so as to continue the normal operation,therefore the reliability is improved greatly.
4.Safety
Equipped with self-discharging resistant and safety devices inside,it is safe and reliable.
5.Without oil leakage
In order to avoid oil leadage during operation so as to protect the environment,it employs the microcrystalline wax as the impregnant,which remains solid atordinary temperature and has a drip melting point higher than 70℃
Conform to: GB12747-91,IEC831-1988 |
