The new 59km long 400kV single-circuit overhead transmission line (OHTL) between Kragujevac and Kraljevo is one of elements of the transmission network which is planned to be built in the first stage of the transition of the 220kV transmission network in Western Serbia to the voltage of 400kV
The subject of this procurement is the construction of a new 400kV transmission line that will connect SS 400/110 / 35kV Kragujevac 2 and SS 220/110 / 10kV Kraljevo 3, which will be upgraded to 400kV voltage level.
