Description
The fog type insulators usually serve in coastlands and rainy areas with large creepage distance structure and well flashover performance in wet condition.
The aerodynamic type insulators, with streamline structure, low deposit rate of insolvable material and great self-clean function take the special protection effect in insulator strings.
The double-shed and tri-shed type insulator with big diamenter, large creepage distance,great self-clean function and strong resistance to pollution, especially serving in droughty, rainless and windy areas.
