Our company produces high quality porcelain insulators has always been known for.

Lightning strike and switching impulse discharge (not including long insulator strings impulse abnormal discharge) always select the shortest flashover path, the easiest way to free air breakdown occurs. Transmission line insulator string using strokes arc angle, once the line being struck by lightning, lightning discharge arc and freewheeling frequency arc along the insulator strings and no air gap in the two strokes arc angle formation. Thereby preventing the discharge arc of the ceramics, porcelain and gold with ablation and porcelain insulators, umbrella tray inside electrical breakdown.
