Overvoltage limiters designed for protecting of high-voltage transmission networks; transformers, switching equipment and HV cable distribution systems against of atmospheric and switching overvoltage effects. The functional part of the limiters consists a column of varistors sized for max. continuous operating voltage UC.
The outer insulating shell is made from silicon material (grey colour). The material of the shell shows high resistance to the effects of surface leakage currents and to electric arc, possesses hydrophobic properties and shows excellent resistance to weather effects, pollution and UV radiation. The cover caps, connecting screws, nuts and terminals are made of stainless steel. With their design and technical parameters, the overvoltage limiters of the PSP series conform to the standards EN 60099-4: 2014 and IEC 60099-4: 2014.
