LINEAR SUSPENDED INSULATOR Russian patent published in 2012 - IPC H01B17/02 

FIELD: power industry.

SUBSTANCE: linear suspended insulator includes metal cap, metal bar and insulating part, which are connected by means of cured cement-sand binding substance. Insulating part consists of a head and a plate. At least one annular rib is made on lower surface of the plate. Base of thickening of lower head part protrudes behind the edge of lower surface of plate. Thickening is smoothly conjugated to inner side surface of head and to lower plate surface. Height of thickening (H_n), as well as depth of reinforcement (H_o) comprise not less than 2 mm each. Value of conjugation radius of thickening to inner surface of head (R_n) is not less than 3 mm, and width (B_n) of thickening is not less than 6 mm. Base of lower part of the plate edge is of drop shape and is conjugated to projection of rectangular shape.

EFFECT: increase in values of allowable voltage as per level of radiointerference and improvement of operating reliability of garlands of insulators at atmospheric and industrial impurities.
