    Abstract: A ZnO surge arrester for high-temperature operation is characterized in that a grain boundary layer between ZnO grains thereof contains a BaTiO3-based positive temperature coefficient thermistor material, which takes 10-85 mol % in the overall grain boundary layer, and when operating temperature raises, the positive temperature coefficient thermistor material in the grain boundary layer has its resistance sharply increasing with the raising temperature, so as to compensate or partially compensate decrease in resistance of components in the grain boundary layer caused by the raising temperature, thereby making the resistance of the grain boundary layer in the ZnO surge arrester more independent of temperature. The ZnO surge arrester thus is suitable for operation where a maximum operating temperature is higher than 125° C., or even higher than 150° C.
