A three-phase power cable line contains three identical single core cables, the axes of which are located at vertices of an equilateral triangle in the plane perpendicular to the cable line sections, each of which has at least a copper or aluminum phase conductor, main electrical insulation of the conductor, two semiconducting screens located on the surfaces of the conductor and the main electrical insulation of the conductor, copper electromagnetic screen and outer insulation sheath. All three cables located inside the case, which is made of magnetic steel sheets in such a way that each of the cables is located inside of the housing, each of which has the same dimensions for each of the three cables, and while the body has on the outer shell in the tangential direction in the plane perpendicular to the section of the housing and along the axis of the cable along the entire length of the cable three non-magnetic gaps are the same size and the same distance from each other. |
