中文摘要	In order to develop a full-featured external insulation design software for ultra-high voltage transmission lines, researching the external insulation design methods and turning to practical software algorithms are the key points for the software development. The specific creepage distance method and pollution withstand voltage method are three commonly used methods of external insulation design in China. Each of the methods has the advantages and its limitations. Taking pollution withstand voltage method as the software algorithm, this paper deeply researches the influence and correction on insulators' flashover voltage from variant factors which should be considered in the external insulation design. The relationships between the insulators' flashover voltage and the factors including salt deposit density, non soluble deposit density, chemical components of salt deposit, uniformity of the pollution deposit, high altitude, ice coating, profile of insulator and suspension mode, etc. are elaborated as well as the calculation process of the method is also studied. Based on these studies, the implementation processes of the software algorithm are put forward. In addition, the selection and dimension of composite insulators in ultra-high voltage overhead line which are the key processes in the algorithm are stressed.
