In order to investigate the source of chemical composition of natural contamination on line insulator in Guangzhou area, natural contamination measurement sites were established, from which the natural contamination was collected, and chemical composition was measured. By enrichment factor analysis, correlation analysis and factor analysis, the source of chemical composition of natural contamination on line insulator was studied. And the main pollution sources of chemical composition of natural contamination on line insulator were configured. It is found that the chemical composition of line insulator comes mainly from man-made pollution. Different pollution sources have different chemical compositions. The analyses reveal that the main pollution source of the composition on line insulator in some region or area can be found out. Thereby, by reducing the specific pollution emissions, the natural contamination on line insulator can also be reduced. Therefore, the contamination flashover can be prevented effectively.
