China FCS Series 15/27/38kV Capacitor Switch - Single & Three Phase, Trusted Suppliers & Factory
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.

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.
Primary incomer terminal (directly connect to interrupter reduce power lost)
Vacuum interrupter (with APG technology with external silicone rubber mold pressure covering)
Outlet bushing (external modular design easy for quality control and maintenance)
High-performance magnetic actuator, high reliable and free maintenance. Demagnetization rate less than 1% after 35,000 tests.
Note: Farady supply special patent modular design mono-stable type magnetic actuator with two coils controlling.
