Surge arresters for AC networks

SURGE ARRESTERS PSP */5 kA 

LINE DISCHARGE CLASS 1

PSP */5 kA - overvoltage limiters designed for protecting of high-voltage transmission systems, transformers, switching equipment and HV cable distribution systems against atmospheric and switching overvoltage effects. The functional part of the limiters consists of a column of varistors sized for max. continuous operating voltage Uc.

SURGE ARRESTERS PSPI */10 

LINE DISCHARGE CLASS 1

PSPI */10 - overvoltage limiters designed for internal use to protect high-voltage transmission systems, transformers, switching equipment and HV cable distribution systems and, in particular, cable heads of enclosed substations from the effects of atmospheric and switching overvoltage. The functional part of the limiters consists of a column of varistors sized for max. continuous operating voltage Uc.
