THE IMPORTANCE OF IMPROVING THE STRUCTURAL DESIGN OF HIGH-VOLTAGE OVERHEAD TRANSMISSION LINES

Abstract. This article analyzes the scientific and technical foundations for improving the structural design of high-voltage overhead transmission lines. During the study, the main structural factors affecting the operational reliability of high-voltage electric transmission networks, support tower structures, material selection criteria, and technological stages of manufacturing were investigated. Particular attention was given to evaluating the influence of using welded steel support structures on mechanical strength, corrosion resistance, and economic efficiency. In addition, wind loads, icing effects, geometric parameters, and structural configurations of support towers were analyzed, and improved solutions aimed at increasing the stability and reliability of power transmission systems were substantiated. Based on the research findings, scientific and practical recommendations were developed to optimize the structural elements of high-voltage overhead transmission lines, reduce metal consumption, and extend service life.
