Refurbishment of Câmpia Turzii Station

The Câmpia Turzii substation is located in the south-western area of the town of Câmpia Turzii, in the vicinity of the Mechel ISCT combine (Industria Sârmei Câmpia Turzii), with Transelectrica as the beneficiary.

The 110/20 kV substation was commissioned in 1954 to supply the ISCT combine, the town of Câmpia Turzii and the Turda - Câmpia Turzii area.

The 220 kV substation was commissioned in 1978, being an important switching substation for the Cluj, Alba and Mureș areas.

The indoor substation had a double busbar system and open-type masonry bays. The existing bays had outdated equipment with a major risk of failure, arranged on two floors, making their operation and maintenance difficult.

The substation showed an advanced state of corrosion and deterioration. In terms of equipment, both the primary and secondary equipment in the outdoor substation had far exceeded their normal service life, which required a large volume of maintenance works.

Within the project, all the electrical power installations were modernised.

To carry out the works, which were conditioned by ensuring continuity in the electricity supply to consumers, it was necessary to set up temporary 110 kV and 20 kV arrangements in two phases for each voltage level.
