description: The topic of the graduate qualification work is "Ensuring thermal stability and non-combustibility of cable lines in 0.4 kV systems". The purpose of the work is to build a visual model that can be used to calculate the final temperature of a cable of a certain cross-section and show on the graph how it changes over time and as it moves away from the center of the conductor. The research set the following goals: - Studying normative documents, scientific articles and other materials related to the topic under consideration. - Gathering the necessary information for the calculations of the method. - Calculation of final heating temperatures for cables of various cross sections and plotting. Checking for thermal stability and non-combustibility according to the received data. - Selecting circuit breakers for each cable based on the results obtained with different input data. - Analysis of the results that were received and description of conclusions and recommendations on the topic. In this work, all the tasks were completed. The special importance of the work consists in the calculations of various types of cables and checking the cables for thermal stability and non-combustibility using a developed specific model for calculating the final heating temperatures of cables by two methods.
