Polymer Insulators for Electrical Equipment, Type IO - Essential for Electrical Isolation

The insulators are intended for conducting and isolation of current-carrying parts of closed switchgear of electric power stations and substations, complete switchgear, connection with open switchgear or power lines. Unit designation: IO xxx/uu-zz, IO xxx/uuu-zzC, where IO - type of insulator; xxx - height of the insulator, mm; yu - nominal voltage of the insulator, kV; zz - number denoting the insulator modification in accordance with the catalogue of the company depending on the insulator mounting configuration. C - is indicated in case the embedded elements of the insulator are made of steel. By default, the material of the insulator embedded elements is brass.
