Filter capacitor device

product outline
product parameters
product manual



1) The filter capacitor complete equipment is consisted of AC filter capacitors, filter reactor, discharge coil, Zinc oxide arrester, isolating switch,circuit breaker, support insulator, connecting busbar, secondary measurement and relay protective device etc

2) It is connected of capacitors with security fence according to electrical requirement, and placed on the steel frame. It is easy to install.

3) It has two kinds of protection mode:

a. Each capacitor connects an external fuse to cut the fault capacitor.

b. Every element in each capacitor adopt reliable internal fuse as the protective device. When one element failure occurs, the fuse blown instantly, other elements are not affected.





1) Altitude:≤ 2000m

2) Ambient temperature:-50~55℃

3) Installation site:Indoor or outdoor

4) The installation and operation site should be no conductive or explosive dust, no harmful gas and vapor, no tense mechanism shake.



Product characteristics


1) Safe and reliable operation, long lifetime.

2) The device adopt modular and building block structure, convenient for overall transport and installation.

3) The device could be designed in different combinations according to detail requirement of customer.

4) Improve power grid voltage quality.

5) Avoid the power grid resonance.





Series capacitor is mainly used in 50Hz or 60Hz, to absorb higher harmonic, improve power quality and compensate to reactive power.
