FFM系列防护电容器参数

用途及适用范围 use and application
　　FFM 型防护电容器可与高压电阻串联构成RC过电压吸收装置，适用与交流35KV 输配电系统中吸收因真空断路器( 或其它不重击穿的开关)开合时产生的过渡过电压，以保护系统内高压电器产品受电压的损害，本产品还可当作高压电容在其他场合下使用。

　　FFMmodel protection capacitorwith high voltage resistancein series being RC is comp osedofvoltage absorption device,itfitswellwith 35kv electric system.due to vacuum breaker(or other non-heavy switch),it produces the transition voltage to protect the product with high voltage from damaging,it is also used on other occasions with high voltage capacitor．
