Renovation of the 35kV and 10kV switchgear for the Vändra 110/35/10kV substation


Civil engineering

Energy supply

Concrete works


Description of work




A new 35/10kV substation was designed and built using the turnkey method. A 20-cell, 10 kV switchgear system and earthing current compensation devices were installed in the new substation building. Airgapped 35kV external switchgear was established next to the building. In addition, the existing access road was rebuilt and at the end of the works, the old substation was decommissioned.

On 1 July 2021, Merko Ehitus Eesti acquired a stake in Connecto Eesti, and the Merko electrical construction business line merged with Connecto. Acting jointly under the Connecto brand makes it possible for us to offer a significantly broader range of services – in addition to the design, construction and maintenance of low, medium and high voltage electricity networks, Connecto also operates in the field of telecommunications and gas networks.
