ELECTRIC CABLE Russian patent published in 2024 - IPC H01B11/06 

FIELD: cable industry.

SUBSTANCE: technical result is achieved by the fact that the electric cable contains a phase line made in the form of a central conductor, and a zero line combined with an earthing line. Phase line consists of at least one current-conducting core with or without insulating shell. Zero line is made in the form of an external conductor consisting of a current-conducting core in an insulating shell and wound on the central phase conductor. Diameter of the outer conductor winding relative to the central conductor is from 3 to 20 mm, the winding pitch is from 2 to 25 mm. Ratio of cross-sections of central and external conductors is from 1:1 to 1:3, and the winding angle of the outer conductor is from 60° to 120° relative to the axis of the center conductor.

EFFECT: reduced effect of external induced noise and interference.
