By comprehensive comparison from testing results in the factory, we obtained differences between mierostructure and electrical parameters. By optimization, we obtained formula and techniques for ZnO arrester with suitable high voltage gradients. The developed ZnO arrester had a voltage gradient of 330 V/mm at the temperature of 1 135 degrees, with a maximum leakage current of IL4 uA. The paper also studied densification process, by means of SEM, and electrical test, and analyzed the sintering temperature affect on microstructure and electrical performance
