Products include:

1, Resonant capacitor ( also named of electric heating capacitor, compensating capacitor, inverter capacitor, power capacitor, medium frequency capacitor)

Resonant capacitor’s application
Electric heating capacitor is used for electric inductive heating system device,, sometimes called the resonant capacitor, the compensating capacitor , the commutation capacitor or the medium frequency capacitor. Electric capacitor is mainly used for not more than 3.6 kV rated voltage, frequency 50 KHZ and under controlled or adjustable ac power system, is dedicated to the improvement of induction heating, melting, stirring or casting device, and the power factor of similar applications.


A, Water cooled resonant capacitor ( have double sided water cooled without group, double sided water cooled with group, single sided water cooled)

B, Air cooled resonant capacitor

2, DC filter capacitor ( have double sided water cooled, singled sided water cooled)

DC filter capacitor’s application：

It is suitable for AC line voltage 380-1250v，the middle DC voltage is below 2kV，high power series resonant induction heating power supply of DC bus with high current and DC voltage support。


3, Protective capacitor ( have protective capacitor、 absorbed capacitor)

Protective capacitor’s application

Protective capacitors are mainly used in the protection ground of series induction heating device and the resistance absorption circuit of direct connection to the protection of large current limiting current.


4, AC parellel capacitor

A, AC High voltage shunt capacitor

AC high and low voltage parallel capacitor: high voltage parallel capacitor is mainly used for more than nominal voltage 1000 V, frequency 50 Hz or 60 Hz AC power system reactive power compensation, improve power factor, reduce line losses, managing electric energy, improve the quality of power supply.


B, AC high voltage filter capacitor

Ac filter capacitor high-pressure: ac filter capacitor is mainly used in 50 hz or 60 hz ac power systems, and other accessories, such as the reactor and resistor connected together, provide one or more of the harmonic current of low impedance channel, by-pass filtering or reduce the harmonic current of system, and improve the power factor of system

C, AC low voltage shunt capacitor
