FCS series 15/27/38kV Single/Three Phase Capacitor Switch
The Farady's new generation FCS capacitor switch is a special electrical field design on vacuum interrupter and switch body insulation for switching capacitive current. Integrated with single or three phase pole mounted capacitor bank to be reactive power compensation.
General
With long mechanical and electrical life design can provides an operational life of over 100,000 maintenance-free operations.
Using the FCS will result in substantial savings from reduced maintenance and maximized bank uptime and will also improve Power Quality.
The FCS all comply with relative standard ANSI C37.66/IEC622771.

Main new advantages of FCS capacitor switch
Note:
Farady Supply special design manual closing device technology with own patent, It applied for normal and abnormal situation closing. Its closing speed(time) comply with IEC62271-100.
This function can offset from magnetic actuator fault which when actuator can't work will cause the major accident.
Primary incomer terminal (directly connect to interrupter reduce power lost)
Vacuum interrupter (with APG technology with external silicone rubber mold pressure covering, increasing the whole insulation and weathering performance)
Outlet bushing (external modular design easy for quality control and maintenance)
Apply ANSOFT design the high-performance magnetic actuator, high reliable and free maintenance. Through 35,000 times opening reverse excitation test, the demagnetization rate less than 1%.
Note:
Farady supply special patent modular design mono-stable type magnetic actuator with two coils controlling. Its the best design for vacuum FCS caps witch.
