description: The main investigated object of the presented work is the cell in which the current-carrying system of the complete switchgear is located. Parameters and geometry are similar to the existing system in KRU "Eltima-Light". In this case, a current of 1600 A and a voltage of 10 kV are taken as the nominal parameters. Based on the existing regulatory documentation, its overall dimensions and internal structure were selected. The dimensions and geometry of the current-carrying system were determined by a numerical experiment. Calculations of the distribution of scalar electric potential, current density, and temperature were performed using the COMSOL Multiphysics 5.5 software package. During the study of a suitable system, the following tasks were solved: 1. On the basis of regulatory documents, the necessary theoretical data for further modeling are presented. Studied and selected modern methods and practices for the production and operation of switchgear. 2. Designed geometry similar to the existing one using the Compas 3D software package. 3. In order to search for the results, the selected geometry was modeled using the COMSOL Multiphysics 5.5 software package. The use of a given material and all physical interactions that exist in real conditions are analyzed. 4. Based on the results, appropriate conclusions were drawn and a number of recommendations were proposed. The work contains a number of graphic materials. They are marked: heating, distribution of scalar electric potential, current density of the busbar current-carrying system. In the conclusion, an assumption is made about the applicability of the studied variation of the current-carrying system for use in mass production.
