| 摘 要： | 文章阐述了合成绝缘子耐雷性能的两面性;分析了在多雷区多回路输电线路上,杆塔比较高时,线路绝缘往往受大气过电压控制,由于合成绝缘子雷电冲击耐压水平较低,因此其使用受到限制,建议对有关规定提出修订。

| Abstract: | In this paper the author described both aspects of withstand - lightning characteristic of composite insulator, and analyzed that as the insulation of multiple circuits is often controlled by atmosphere over- voltage in heavy- lightning area when the towers are higher, so that its application would be limited, and gave an advice to revise relative rule. |
