Self-healing type:
It adopts the new material with self-healing function as soon as the breakdown of the voltage occurs, at the breakdown point high temperature is generated due to the arc, so that metal conductors can quickly dissipate and evaporate, thus forming an insulating area.
Miniaturization:
It uses the latest technology to make the capacitor smaller, lighter to meet users' needs for the room.
Overvoltage Protection：
If the overvoltage occurs or the life of the capacitors approaches, the internal pressure of the condenser will increase and the pressure relief mechanism of the housing will be deformed, then the internal metal wire should be cut off to avoid overheating. caused by overload and even explode.
