Purpose: To analyze the factors influencing the service life of urban electric transport cables, as well as the existing calculation models of insulation aging. Methods: The investigation will examine the factors that most influence the insulation of cable lines in urban electric transport. The efficiency of existing mathematical models will be evaluated based on the analysis of these factors and the results obtained. Results: The paper presents a comprehensive monitoring of cable lines of urban electric transport to date, as well as an analysis of the factors that influence the normal aging of cable line insulation. The efficiency of the existing mathematical models for calculating the cable insulation service life has been evaluated. Practical significance: The results of the investigation carried out have enabled a further step to be taken in the improvement of mathematical modelling for the calculation of cable line insulation service life. This can be applied in the method of ongoing monitoring and analysis of the condition of cable lines laid under the earth formation, in order to prevent potential emergencies.
