摘　　要：本文据对不同污秽地区409串（2994片）线路用悬式绝缘子的盐密（ESDD）测试，探讨了绝缘子串表面污秽分布规律和益密均值的简化测量方法，对绝缘子悬挂高度对积污的影响；绝缘子串带交流电与不带电积污的差异，以及不同型式的绝缘子在相同环境下沉积污秽的不同做了比较。结论可供线路绝缘设计、选型和运行维护工作参考。Based on the long geriod measurement and test of ESDD on a large amount of suspension insulator strings on transmission lines， the rule of distritiution of pollution diposition on surface of suspension insulator and the simplified method of measuring salt density is discussed in this paper． The influence of the height at which the insulators are suspended on the pollution deposition， the differences of pollution deposition on different types of insulators under the same environment and that of charged and uncharged insulators are compared．
