HIGH-VOLTAGE POST-TYPE INSULATOR Russian patent published in 2013 - IPC H01B17/26 

FIELD: electricity.

SUBSTANCE: insulator contains a base and four radially connected rectangular ribs which are installed symmetrically along the base length. Through holes are made in top elements of the ribs. V-shaped grooves perpendicular to each other with depth of 5-10 mm are located at both sides of the base, at its butt ends, between rib holes and in the base centre. The insulator structure isolates the current-conductive wire from earth wire and atmospheric precipitation and takes force of conductor tension affecting compression of the base and ribs.

EFFECT: improving mechanical strength of the insulator.
