Self-healing shunt capacitors

Brief Introduction

The self-healing shunt capacitor uses metallized polypropylene film as the insulator and electricity pole. Primarily applied for alternating current electronic power system with maximum voltage of 1000V and frequency between 15Hz and 60Hz to compensate power, improve the power factor, reduce the circuit exhaust, economy electric power and increase power supply quality.
Special features:
Small size, light weight, low power consuming, stable capacity, self-healing, long life
Unique structural design makes every component have good heat radiating function.
Be able to work under a higher temperature (Max 50 )
Standard outer shape design, easy for assembly.
Meets the requirements of international standard IEC60831

Application

Low Voltage Shunt Capacitors of self-healing type low voltage shunt capacitor, made of the advanced metalized film, is produced strictly in accordance with the National Standard GB12747-2004 and IEC Standard IEC60831-1:1996 by the introduced advanced foreign techniques and equipment. The device is mainly suitable for low voltage electric network to improve power factor, reduce reactive loss, and better the voltage quality.

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 Small volume and light weight It is only 1/4 and 1/5 of the weight and the volume of the outdated products respectively.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 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 over voltage, 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 leakage during operation so as to protect the environment, It employs the microcrystalline wax as the imp regnant, which remains solid at ordinary temperature and has a drip melting point higher than 70 .
