HIGH-VOLTAGE SUSPENDED INSULATOR Russian patent published in 2013 - IPC H01B17/02 

FIELD: electricity.

SUBSTANCE: insulating part consists of a head and a plate made as a sphere segment with variable thickness. The ratio of leakage path length (L) to plate diameter (D) is equal to 0.9-1.05. The ratio of plate thickness near top edge (h) to plate thickness in front of drop-shaped thickening of its edge (h₀) is equal to 1.2-1.4. Circular rib has a vertical section shaped as a flattened cone with rounded top and flaired with the lower surface of the plate. Thickening of the lower part of the head is flaired with inner surface of the head.

EFFECT: improving aerodynamic performance and operating reliability of insulator chains in conditions of atmospheric and industrial pollution.
