In the current work investigated the thermal regimes of cable linesin tube blocks of various dimensions, taking into account convective heat transfer, thermal conductivity and radiation heat transfer.The principle of loading cables by an analytical method is derived.The simulation of the heat exchange process in the cable-pipe system by the finite element method was carried out and the optimization of the cable load was carried out in compliance with the specified optimization criteria.The throughput of cable lines intubeblocks has been calculated.An analysis of the regulatory documents was madeand recommendations were developed for laying cable lines intubes, as well as the methods of thermal calculation and permissible current load were clarified.
