The invention relates to the field of power engineering and telecommunication and can be used in the identification is produced, transmitted and consumed electricity and to determine the circuits in the cable. The objective of the invention is to provide a cable for raising the reliability determining circuit or transmission line, which is the transmission of electricity from the source to the consumer in the electricity system, as well as circuit in the cable, including on the ground. The technical result of the invention is achieved by the fact that the cable contains a cross-section along at least two subfields of materials, one of which is a conductor, the other dielectric, and at least part of the boundary line section and/or at least part of the boundary line of the sub-regions of the conductor and/or dielectric is made in the form of a fragment of an oblique conical section of a right circular cone. This provides asymmetric localization lived in the cross section of the cable relative to the screen or to the longitudinal axis of the cable, which increases the difference electroosmotic characteristics of the cables due to the individual geometric parameters which can be used for identification produced, transmitted and consumed electricity and to determine the fault in the cable, including the earth.
