35 kV Power Line between Paraćin and Popovac

Works including delivery of goods for the construction of 35 kV power line between Paraćin and Popovac were carried out in 2018 across Paraćin and Ćuprija Municipalities, under investor ODS EPS Distribucija, Jagodina Branch.

The existing 35 kV power line between 110/35 kV “Paraćin 1” Substation and 35/10 kV “Paraćin 6” Substation (Popovac) consists of three different sections, and different types of works were executed in each section:

• The first section was built on double-circuit steel lattice towers. This section was in good condition and the following works were carried out: rehabilitation of towers in terms of completing missing positions, replacement of existing insulation and replacement of the existing protective cable with OPGW.
• The second section stretches from the point of connection of the first section to the point of connection to the old 35 kV power line for Popovac stretching from the direction of Ćuprija and Jagodina. This section was in good condition and the following works were carried out: rehabilitation of concrete towers, which showed concrete damage and cracks, replacement of insulation and replacement of the existing protective cable with OPGW.
• The third section stretches from the point of connection of the second section to the 35/10 kV “Paraćin 6” Substation and represents the worst section. The following works were carried out there: replacement of existing reinforced concrete towers with steel tubular towers, replacement of conductors, replacement of insulation, replacement of the existing protective cable with OPGW. In addition, two line disconnectors for the purpose of line sectioning were installed on this power line.

The existing 35 kV power line between Paraćin and Popovac supplies 35/10 kV “Popovac” Substation. The power supply to this substation is radial and any dropout of this line leaves a large number of consumers without electricity. On the other hand, this line consists of three sections, one with steel lattice towers, the other with reinforced concrete towers of the “Karpoš” type and the third with reinforced-concrete towers which are over 50 years old. Poor insulation over the entire power line and worn-out third section caused many outages.
