FWF type protective capacitorDetailed product description：

The FWF type protective capacitor can be connected to a high voltage resistor to form an RC voltage absorption device, which is suitable for absorbing excessive overvoltage caused by the opening and closing of vacuum circuit breakers (or other non piercing switches) in AC 35KV transmission and distribution systems, to protect high-voltage electrical products in the system from voltage damage. This product can also be used as a high voltage capacitor in other situations

Main technical specifications of FWF type protective capacitor Main Technical Specifications
1. Capacitor deviation -5% to+10%
2. Tangent value of loss angle tan δ ＜ 0.05%
3. The electrical strength of the dielectric is 2.15u, lasting for 1 minute
4. All other technical requirements are in accordance with GB.T4704-32 High Voltage Parallel Capacitors

Service Consideration Conditions
1. The installation and operation of capacitors shall not exceed an altitude of 1000m, with an ambient air humidity of -40 to+40 ℃ and a relative humidity not exceeding 98%.
2. The installation site should be free of corrosive gases, vapors, conductive or explosive dust, and there should be no violent mechanical movement.
3. When the capacitor is put into operation, the residual voltage on its terminals shall not exceed 10% of the rated voltage set point.
4. Overcharge
4.1 Stable overvoltage continuous operation voltage of 1.00u, and can operate for a long time under 1.2u, power frequency overvoltage.
4.2 The withstand of the operating voltage capacitor is not affected by the 5u transient overvoltage (peak value) generated by the breakdown switch
4.3 Steady state overcurrent capacitors can operate under 1.5In steady-state overcurrent, which is the result of the combined effects of harmonics, maximum tolerance, and overcurrent up to 1.2.
