description: This work is devoted to the study of a current-carrying system made of aluminum. Mathematical modeling of heating of aluminum and copper current-carrying systems is performed in order to compare the temperature obtained in the calculation with the standard data. A heating test was also performed on a switchboard with an aluminum current-carrying system and a similar copper current-carrying system. Tasks that were solved in the course of this work: 1. Calculation of models of current-carrying systems made of aluminum and copper. 2. Calculation of models of distribution cabinets with current-carrying systems made of aluminum and copper. 3. Calculation of models of distribution cabinets with current-carrying systems made of aluminum and copper in the air area. Mathematical modeling was performed in the COMSOL Multiphysics program. The geometry of the calculated area was created in the COMPASS 3D program. The dimensions of the geometry of the calculated area were taken from the product catalogues of the company "Samara Electroschit". As a result of solving the problem, high-quality drawings with heating temperatures and isothermal circuits of current-carrying systems made of copper and aluminum were obtained. Drawings were also obtained with heating temperatures and isothermal circuits of distribution cabinets with current-carrying systems made of copper and aluminum in the air area. Based on the results obtained, it can be argued that the modernization of the distribution Cabinet with a unique current-carrying aluminum system of the company "Samara Electroschit" is appropriate.
