Insulators With Higher Pollution Flashover Voltage

Strong resistance to pollution flashover. The surface of high-voltage polymer deadend insulator is hydrophobic, and water is in granular form on it. This type of porcelain dead end insulators is not easy to form a conductive path. In addition, the high-voltage suspension insulator umbrella disk has a small diameter, large creepage distance, high surface resistance and small leakage current. Therefore, suspension composite insulator has a higher pollution flashover voltage.
