Meanwhile, the factors which affect the flashover voltage of ceramic insulators were analyzed, the methods for improving the hold-offvoltage were recommended from the in.
接触网覆冰不仅影响接触线的弛度、支柱的容量，在一定程度上还影响着接触网绝缘子的闪络电压。

The parameters which affect the holdoffvoltage of the one stage pseudo spark switch such as the working gas, the pressure, the gap distance and the hole diameter of the electrodes have been studied.
