The analysis of the factors affecting the reliability of the 110 kV transmission line in conditions of extreme continental climate. The distribution of the causes of failures of overhead power lines, the ranking and systematization of the main factors affecting the reliability of OPL’s are presented. A diagram of the distribution of failures by months and the classification of failures by main elements for overhead power lines with voltage of 110 kV in Sughd region are given. Using the method of correlation and regression analysis was obtained, the equation of multiple regression of the influence of natural and operational factors on the reliability of overhead lines. The equation with sufficient accuracy reflects the actual impact of natural and operational factors on the reliability of overhead power lines. At the end, it was concluded that the “life curve” of 110 kV high-voltage transmission lines in the Sughd region is in the area of equipment wear and requires a radical reconstruction taking into account the changed electrical loads at this stage and in the future.
