ELEKTROBUDOWA SA, as the first company in Poland, has extended the switchgear of another manufacturer

ELEKTROBUDOWA SA has extended the existing 110kV switchgear in Turów power plant by adding two functional bays manufactured by the Company. The added infrastructure is compatible with the existing switchgear and guarantees full functionality of its operation. It is the first project of this kind in Poland.

The works, which included designing, manufacture, installation and commissioning of two functional bays of GIS switchgear type OPTIMA, were performed under the contract for extension of the existing indoor 110kV SF6- insulated switchgear at the site of the Turów Power Plant (PGE GiEK SA), which did not have any standby bays to which the stand-by starting transformer for the new power unit and the stand-by transformer for feeding the existing 110kV switchgear of unit 6 could be connected.
ELEKTROBUDOWA SA, as a leading domestic manufacturer of switchgear and a long-standing partner of Turów Power Plant, proposed to install the bays of indoor 110kV SF6- insulated switchgear (GIS) type OPTIMA 145, as an extension of the existing switchgear.

The scope of works covered: engineering and performance of connecting the offered bays to the existing switchgear.

The extension of the 110kV GIS by building on additional bays made by another manufacturer is the first application of this type in Poland.

To the existing, more than 20-year-old switch bays produced by another manufacturer, the new, considerably different in respect of the construction, switch bays from ELEKTROBUDOWA SA were connected. The successful connection of the functional bays with different standards of busbars in respect of dimensions, busbar gauge or pressure was possible owing to the genuine commitment and considerable experience of ELEKTROBUODWA’s personnel and an innovative approach to the task.
The connection of the two new functional switch bays to the existing bays was performed in December 2017, resulting from operating capability (obtained switching out for the busbar systems) of the auxiliary switchgear of the plant. At present, the new GIS bays are permanently coupled with the busbar systems of the 110kV switchgear, waiting – on the side of the Investor – for the 110kV cables to be connected, what is planned for April (bay No. 13) and July (bay No. 14) of 2018.

Installation of the gas connections was performed with only one busbar system disconnected, while the other system had to be live all the time, as operation of the GIS 110kV in the power system of the Plant was a priority.

All works were performed professionally, in compliance with the safety requirements, with continual participation of Investor’s representatives.
