Features Analysis of Composite Supports Application for Electric Power Networks in Ukraine

The peculiarities of operation of supports from composite materials in the world are analyzed and the prospects of using such supports for overhead transmission lines in Ukraine are grounded. The algorithm for mathematical calculation of electric energy losses for overhead power lines, which allows taking into account the specific parameters of the overhead transmission line depending on the support type used, has been developed. Calculation of the value of electric energy losses in 330, 110 and 35 kV electrical networks, which are performed by overhead transmission lines using reinforced concrete, metal and composite supports, was made. The analysis of the obtained results showed that the use of supports from composite materials will make it possible to reduce losses during electric power transmission over overhead transmission lines, to reduce the protection zone for the overhead transmission lines under investigation, to reduce service costs and increase the efficiency of electric networks.
