The project is to be implemented in two tasks: 1) Reconstruction of Dąbie station, 2) Change of power supply station Zdroje. Task 1 consisting of the reconstruction of the Dąbie station will be carried out in a two-step mode – separate design and construction and assembly work. This task will consist of the conversion of the station into a 2-system system with 5 linear fields of 110 kV and 2 transformer fields in air isolation, Task 2 consisting of changing the power supply of the Zdroje station will be carried out in the “design and build” formula in turnkey form, i.e. the order will cover all investment tasks, including possible administrative procedures. This task will consist of the construction of a parallel cable line LK 110 kV 1000 mm² in addition to the overhead section of the line – decoupling, using a triangular cable with a long working temperature of 90 °C, with fibre optic fibres in the area of return veins installed in the production process of the cable (if the existing overhead line is left).
