description: This work is devoted to the study of defects and diagnostic methods of cables and couplings for a cable line with 35 kV cross-linked polyethylene insulation and the development of measures to increase the reliability of the cable line. Tasks that were solved during the study: 1) Study of the features of defects in a cable line with insulation made of cross-linked polyethylene. 2) Analysis of diagnostic methods for detecting defects in a cable line with insulation made of cross-linked polyethylene. 3) Calculation of the reliability of the cable line and the impact of measures to reduce defects in cables, couplings and cable lines on the reliability of the cable line. As a result, the reasons for the failure of the cable line have been studied, cable damage occurs most often due to excavation work in places where the cable line is laid, coupling damage occurs most often due to poor-quality installation. Based on the calculations carried out, it turned out that carrying out complex measures to reduce mounting defects of couplings and operational defects of cables has a positive effect on the reliability of the cable line, production defects have a minimal effect.
