People of Electromontaj: 400 kV OHL Cernavodă - Stâlpu

The latest Electromontaj project, of an impressive magnitude, in our first documentary film: “The people behind the 400 kV Cernavodă-Stâlpu overhead power line”.

It’s about the incredible people who made it happen with passion and emotion and effort.

400 kV OHL Cernavodă-Stâlpu is a project developed by Transelectrica TSO, co-financed by the Mechanism for Connecting Europe – Connecting Europe Facility and implemented by the Electromontaj group, as contractor.

The project is part of the North-South Interconnection East Electricity Corridor and aims to strengthen the cross-section between the west coast of the Black Sea and the rest of the European system , contributing at the same time to the strengthening of the electricity transmission network in Romania, to the increase of the interconnection capacity between Romania and Bulgaria and to the integration of the wind energy produced in the Dobrogea area.

The overhead power line is 160 km long and crosses the territory of three counties: Constanța (6 km with double circuit), Ialomiţa (94 km with double circuit and 5 km with single circuit) and Buzău (54 km with double circuit), with 22 territorial administrative units.

This overhead power line includes the crossing of the Danube in the Cernavodă area and the Borcea branch, near the Stelnica commune, with a length of crossing panels of 2.6 km at the Danube and 1.7 km at Borcea. The crossing will create a common corridor with the Danube crossings and the existing 400 kV single circuit Cernavodă – Pelicanu and Cernavodă – Gura Ialomiței lines.

The crossing of the Borcea branch was made with high-voltage towers, 100 m high, and 150 m high towers are used to cross the Danube, these being the highest high-voltage towers in Romania. The towers were produced by Electromontaj in its own production unit, at the Electromontaj High Voltage Towers Factory, and were tested in its own test station in Bucharest, one of the largest in the world.
