Annotation: The article deals with the stress-strain state of the structural elements of large transmission line crossing 154 kV «Kremenchuk Hydroelectric Station – Kremenchuk Heat and Power Station» across the river Dnipro under reconstruction with replacement of conductors (with a comparison of two types of conductors – ACSR and АААС Aero-Z). 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 stresses and efforts in the most stresses elements of supports. As a result of the calculation performed during the reconstruction of the local strengthening of structures of transition supports. The reconstruction has improved the reliability of power supply circuits in Kremenchuk due to increase of imparted electrical power without replacing the existing supports.
Keywords: overhead power transmission line (PTL), large transmission line crossing, tower, reconstruction, stress-strain state, software package.
