\u00a0The paper analyzes the number of emergency shutdowns of overhead and cable power lines with a voltage of 6\u2013110 kV in Khujand urban electrical networks. The intensity of failures of power lines with a voltage of 6 — 110 kV in the Khujand city electrical networks is given. The data are presented in tables and charts. The reasons for reducing the level of reliability of electrical equipment in Khujand urban electrical networks are indicated. The measures to ensure reliable operation of electric networks with voltage of 6 — 110 kV are given. It was concluded that in order to ensure reliable operation of electric networks with a voltage of 6\u2013110 kV, it is necessary to carry out such measures as the reconstruction of single-circuit OPL and transfer them to double-circuit OPL overhead transmission lines, redundancy of individual elements (transformers, power lines, etc.) power supply systems, automating the calculation of all power supply reliability indicators when planning maintenance, timely implementation of preventive maintenance (PM) according to the schedule of work, etc.<\/em><\/p>\n
