Execution of works on the upgrade of 110 kV Transmission Line no.115/4 between Požega Substation and Beljina Junction

The upgrade of 110 kV Transmission Line no. 115/4 between Požega Substation and Beljina Junction was carried out in 2023 in local communities Markovica and Rtavi, Lučani Municipality, under investor China Communication Construction Company Ltd. Completed works included reconstruction and relocation of the transmission line to the zone of intersection with the motorway E-763 Belgrade – Southern Adriatic, road section Pakovraće – Požega.

Route of the existing 110 kV transmission line number 115/4 overlapped the newly designed bridge number 15 of the designed E-763 motorway in the approximate length of 800 m. That is why a reconstruction and relocation of the transmission line was needed to be done. An intersection under the approximately right angle with the future motorway was performed on the new transmission line route, followed by a route that runs parallel to the motorway on a proper distance. Three new angle (tension) poles were built as well as the three new load-bearing pillars, manufactured and installed, newly galvanised steel-truss construction protected upon installation with a duplex system of anticorrosive protection. New Al-Fe conductors were installed on the reconstructed section, as well as the 50 mm² protective rope, U120B glass insulator, suspension and external equipment.

Reconstruction that has been performed this way shall provide a safe and quality transmission of the electric power, as well as the safe traffic flow in the intersecting zone of the power facility and road infrastructure.
