The technology is based on the creation and use of methods for optimal placement of cables of multi-circuit CL for the organization of mutual vector compensation of their magnetic field, as well as new methods and means of shielding the magnetic field of the CL. For the first time, energy-efficient magnetic field contour shielding systems (CSS) have been proposed, which provide high (at least 7 AU) shielding efficiency due to the formation of a strong and asymmetric magnetic connection of CSS with cables of individual phases of cables using ferromagnetic elements of their design. corresponds to the level of the best foreign analogues, but in contrast to them have a lower material consumption by 20-30%, and by removing the screen contour by 0.2-0.3 m from the cables of the cable, do not have a thermal effect on the cable and therefore do not limit it bandwidth.
