This article studies the cable for distribution networks with a voltage of 6 (10) kV and their damage during operation. The analysis of technological disruptions was carried out for ten branches of PJSC ROSSETI from 2018 to 2022. The data were systematized according to Order No. 90 of the Russian Ministry of Energy, dated 2010. Emergency power outages in the cable networks of Chelyabinsk were analyzed in detail. Using the example of Chelyabinsk city networks, network damage during operation is considered.
