The flashover voltage of iced insulators of transmission lines is affected by the electrical characteristic of ice. 冰的电气特性影响输电线路覆冰绝缘子闪络电压。
It was concluded that charge injection and recombination would restrict the field electron emission, and increase the threshold voltage of flashover and decrease its scattering. 发生在绝缘体表层的电荷注入和复合过程能够在一定程度上抑制场致电子发射，从而提高沿面闪络电压，并降低闪络电压值的分散性。
