description: This work is devoted to the study of possible ways of laying an underground cable line at the moment, the choice of the optimal solution and its calculation. Tasks that were solved during the study: 1. Investigation of the problem of finding an overhead power line (OHP) in the megalopolis; 2.Consideration and comparison of such underground cable options as superconducting cable, oil-paper insulated cable, cross-linked polyethylene cable; 3.Choosing the most suitable option for the conditions; 4. Calculation of cable parameters according to the design methods of cable lines used by PJSC Â«Rosseti LenenergoÂ»; The work was carried out, in part, on the basis of the design department of PJSC Â«Rosseti LenenergoÂ», where the actual material was collected: line capacity indicators, regulations for the design of the line. Calculations of the limiting long-term current, the magnitude of the limiting one-second short-circuit current (short circuit) were carried out. The analysis of the heating of the cable line was carried out on the basis of solving a static thermal problem in the Elcut Student program. As a result, various types of underground cable lines were studied, a cable option with cross-linked polyethylene insulation was selected, limit parameters were calculated and a suitable cable brand was selected, the lengths of cables that became unusable due to the effects of a short-circuit arc were calculated.
