Annotation: The subject of research in this article is the double circuit large transmission line crossing 154 kV «Kremenchuk Hydroelectric Station – Kremenchuk Heat and Power Station» on the river Dnieper. The responsibility of the given construction is not established only by that fact, that given overhead transmission line is one of power supply lines of Kremenchuk, but also its intersystem value. Calculations have been performed by means of developed software package, which is based on the digital and analytic methods of definition of stresses and deformations in element of structures of OPTL as part of common system. That allowed defining numerical value of loads from the conductor line and overhead ground-wire cables in a normal and emergency mode of operation on the structures of overhead power transmission lines, as well as efforts in the most stresses elements of supports. According to the results of calculation during the reconstruction it was made the local strengthening of structures of towers and supports. This article describes the manufacturing process of works on replacement of conductors and overhead ground-wire cables by installation them on the surface of water, that allowed to reduce term of reconstruction and loads on the supports. On the whole, realization of work allowed raising indicators of imparted electrical power when the considerable reduction of materials-output ratio (without renewal of existing supports), and also to increase the reliability of the intersystem of OPTL section.
Keywords: overhead power transmission line (OPTL), large transmission line crossing, reconstruction, conductor line, tower.
