High current loads
Since the powercapacitor of the power factor correction equipment needs frequent switching,it must be able to withstand high current during switching peak,and does not affect the life of the capacitor.Due to the special design of the contact area of technology,the impact of current allowed to reach 300In.

Self-healing
When the capacitors due to overheating,overload or near the end of life,they may breakdown.This will produce a small arc,it can evaporated of the breakdown region of the metal layer within a few microseconds.The high temperature atmosphere generated here blows the gasification metal layer out of break region,formed an insulating region in the breakdown region without metal layer.During and after the breakdown occurred,the capacitor can still work.The loss of self-healing capacitors is less than 100pf.The capatitor has a lifespan of up to 210,000 hours with more effective self-healing and low dielectric loss,and the operating temperature is greatly reduced.

Overvoltage lockout
Power capacitors are with overpressure swelling fuse.If the fault point repeatedly heal,causing internal pressure to rise,and reaches a certain value,the expansion fuse acts.At this time,the aluminum cylinder cap is in a slight bulge.The fuse was pulled off.Expansion fuse capacitor can be disconnected from the safety of the power system.
Due to further improve of the process and closed,the capacitor can be accessed the performance of oil capacitor while significantly reducing the volume.
Each capacitor unit mounted in the housing and applied technology greatly resin medium and to ensure the heat insulation of the capacitor to ground, to improve the life of the capacitor.
All capacitor units consist of polypropylene film with special metal around the system,installed the metal shell and cover in the capacitor monomers.The shell adopts special double crimping process and new sealant assembly to ensure perfect sealing and over pressure protecting for safe operation of the system.
All capacitors are produced using environmentally friendly materials, in line with standard EN60831-1/2.

Security and Protection
In order to protect the reliability of the capacitor,each unit is equipped with over-pressure protection device.
The function of over-pressure protection device is to disconnect when the capacitor do not automatically resume at the end of life,which use short-circuit current overheating the internal pressure generated by the decomposition of the film so that the terminal contacts disconnected.
Over-pressure protection device with dimensions to ensure that even in the case of high energy density but also to ensure maximum safety and protection of the earth crowbar term.
This protection has to rely on specialized engineering and technical implementation: When a failure occurs, the contact off because of the pressure , to ensure that the insulation is intact and prevents capacitor shell explosion or expansion. Means designed to guarantee the optimal size of the short-circuit current in the low and high short-circuit current,can be more effective and efficient operation.
