COVER OF SUSPENSION LINE INSULATOR Russian patent published in 2015 - IPC H01B17/02 

FIELD: electricity.

SUBSTANCE: invention is related to electric engineering, in particular to structural components of high-voltage suspension insulators for overhead transmission lines and is a device of an auxiliary insulating part used together with the main insulating part of the insulator and is being a part of a composite design. The auxiliary part is made of tracking-resistant organosilicon rubber shaped as a ring with protruded circumferential fins of different configuration with surface of inner ring diameter, which repeats completely the shape of external rim of the main insulating part of the insulator.

EFFECT: attaining the best operational properties and hydrophobic property, reducing weight, vandal-proofing, and increasing length of leakage path.
