On June 15, 2018, the construction of the HBM 400 kV Loop of the Řeporyje – Prosenice line began.

Masts of the “Danube” type will be used on the New Line. These are single-stem trellis structures for two systems with a delta phase arrangement and two fiber optic ground cables.

The purpose of the construction is to strengthen the connection of the Mírovka transformer station to the transmission system, because the looping of the lines will ensure higher variability of operation, reliability and safety of the operation of the transmission system.

The construction crosses two 100kV ČEZ lines and two E.ON lines, and also meets three railway lines and rivers, the Sázava and the Šlapanka. Furthermore, it crosses several times with HV 22kV lines. Some sections are therefore very demanding both in terms of coordination and construction.

We thank the investor ČEPS.

The expected completion of construction falls towards the end of 2019, i.e. December 31 of this year.
