Double circuit large transmission line crossing 150 kv on the Dnieper river
This paper presents the reconstruction of the double circuit large transmission line crossing 150 kV “Kremenchuk Hydroelectric Station - Kremenchuk Heat and Power Station” through the Dnieper River due to the suspension of new conductors. 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. During calculation of stress-strain state of steel towers whole number of interdependent factors is taken into account, which are climatic conditions, overhead lines design parameters (length of span, sag, clearances), terrain profile and scheme OPTL, difference between the tensions in adjacent anchor sites, calculation modes and load combinations, etc. Attention is accented to a local strengthening of metal structures of transition supports and foundations. Using the new conductors with a large cross section allowed to increase the energy reliability of Kremenchug city due to the power increasing of the line without replacing the existing towers.
