A high-voltage insulator includes an insulating rod (1) having metallic ends (2) and insulating element (3), linked with rod by means of binding material (4), an insulating element is implemented as cylindrical body (5) which has ring ribs (6) being both equal and two different diameter. The ring rib of bigger diameter (7) and smaller diameter (8) are alternated. The between ribs distance (9) is in the range of 21 to 33 mm. The ratio of max. height (10) of insulating part to min. height is no more than 2,63 to 1. Min. height of the insulating part is no than 180 mm. The ratio of max. diameter of end rib and min. diameter of end rib is no more than 2,88 to 1. |
