China Intelligent Self-Healing Low Voltage Power Capacitor, Find details about China Film Capacitor, Polypropylene Film Capacitor from Intelligent Self-Healing Low Voltage Power Capacitor
Main Features
1, Small Volume and Light Weight : Its volume and weight are only 1/4 or 1/5 of the old product because of adopting new dielectric --- metallized polypropylene film.
2, Low dissipation factor: The actual value is lower than 0.1%, so the capacitor itself has low energy consumption,produces less heat, with low temperature rise,and long service life.
3, Excellent self-healing performance: It can self-healing rapidly and resume normal work at once,if localized breakdown caused by overvoltage. So the reliability is greatly improved.
4, Safety: With built-in self-discharge resistor and safety device. The built-in self-discharge resistor can discharge electrical energy in capacitor automatically,the safety device can disconnect power supply in time when a failure happens on capacitor, to avoid further malfunction,and ensure use security.
5, No oil leakage: The capacitor adopts advanced semi-solid impregnant whose dropping-melting point is above 70ºC,there is no oil leakage during use,then it avoids environmental pollution.And capacitor will not fail due to oil leakage.
