The paper lists operation features of the 500 kV overhead power lines in the Republic of Tajikistan. It presents the impact of the terrain and ambient air temperature on the change of electric field intensity of industrial frequency near the overhead 500 kV power lines. The results of calculations of residence time for line personnel in areas with different voltage of industrial frequency electric field within the working day are provided. Applicability of calculate cards for electric field intensity distribution of industrial frequency is useful at servicing these lines. The article provides the example of job organization at clearing the trails along the overhead power line located in the southwestern part of the Republic of Tajikistan. With the calculate cards of distribution of the electric field intensity of industrial frequency along the 500 kV overhead transmission lines, service works at these lines may be organized in such a way that the personnel work time near electric field will not exceed 8 hours. This reduces a negative effect of electric field of industrial frequency on staff serving the 500 kV line.
