CAPACITOR ADVANTAGES:
1. Safety
*With over pressure protection device, automatic power disconnection if happened to the fault or overload;
*The residual voltage will drop to 75V or lower in 3 minutes after capacitor being disconnected from power source.
*The adoption of European structures and tensile explosion-proof technology ensure higher security, which is up to the quality and technology standard of Europe.
2. Full-dry construction
*Fine vacuum silicon oil prevention.
3. Durable
*Constructed with special composite electrical material and reinforced insulation material. The spoilage is low with tiny loss of capacitor; Normally capacity drops 2% in 2 year-long operation.
4. Full metal construction
*Use special workmanship for processing, high reliability, novel appearance, convenient for installation.
Operation of capacitor internal protective device
In the event of capacitor internal failure of aging at the end of the capacitor's operational life, an increasing number of self-healing breakdowns may cause rising pressure inside the capacitor element. To prevent it from bursting, each capacitor element is designed with internal pressure sensitive interrupter (Protective Device). With rising pressure the cover will bulge to disconnecting copper taps at weak points from the cover, and the current path is interrupted irreversibly to avoid the relative disaster.
