Product Introduction：

The bell-type pollution-resistant suspension insulator utilizes the asynchrony of the damp inside the umbrella and the high edge under the umbrella to suppress the discharge. The artificial pollution flashover test voltage is higher and the anti-fouling performance is better. Suitable for industrial dust, chemical, saline, coastal and foggy areas.

The lower surface of the bell-type insulator has deep grooves, and the inner cavity under the umbrella is not easy to be damp, but when the inner cavity is fully damp, the upper surface of the umbrella has been excessively damp, resulting in the loss of its pollution, thereby increasing the pollution withstand voltage of the insulator. It is the effect of the long creepage distance of this umbrella protection.nd foggy areas.
