Product Introduction：
The utility model discloses an anti-pollution disc-shaped hanging type porcelain insulator which comprises a metal cap, an insulating porcelain element and steel feet. The utility model has a design gist that the insulating porcelain element is of a three-layer umbrella skirt structure, and a middle umbrella skirt is a small umbrella skirt. The utility model has the advantages of good pollution flashover resistant performance and good rain flashover resistant performance, the artificial pollution flashover voltage of the utility model is enhanced within 46.2% and 72.5% of the artificial pollution flashover voltage of ordinary anti-pollution disc-shaped hanging type porcelain insulators under identical foul conditions, the utility model is especially suitable for heavy polluted areas, and in addition, connecting hardware and the structural height of the utility model is as same as the connecting hardware and the structural height of ordinary anti-pollution disc-shaped hanging type porcelain insulators, products of the utility model can be exchanged, and the utility model is suitable for not only new built lines, but also the change of ole lines.
