description: This work is devoted to the development of a method for determining the heating of a cable core based on the data of a cable line monitoring system and finding the predicted limit load of the line from the data received from the sensor. The research set the following goals: 1. Studying the features of the application of the CL monitoring system; 2. Creation of a finite element model of cable lines to obtain averaged daily graphs of the current and temperature load of the cable; 3. Development of an analytical model for the connection between the screen and cable surface temperatures; 4. Creation of a program code for obtaining data on the continuous current load of the cable; 5. Simulation of the cable limit load process. During the development of the method, an analysis of the existing methods of thermal calculation of cable lines was carried out and a variant of finding the long-term permissible phase current and heating temperature for the current atmospheric and geophysical conditions was compiled. The technique was tested using the COMSOL MultiPhysics program, which showed the applicability of this calculation. Based on the obtained dependences of temperature on time and the simulated temperature distribution in the cross section of the cable line, a model of an extremely loaded line was obtained. The use of such a calculation will make it possible to achieve a significant reduction in the cost of materials by reducing the cross section of the cable core and to increase the development of operational working solutions.
