Within the project 'Ovčiarsko-Lány-Extension of LVK' we have successfully implemented a series of important tasks, including the dismantling of the existing PRIS 2.2 and its replacement with a new PRIS in the cadastral area of Ovčiarsko on the parcel number KNC 416/14. In addition, we have carried out the installation and mounting of the proposed PRIS 7 disconnection cabinet, as well as the installation of a new (N)AYY-J ground cable. Our work also included the important task of installing an optical protector, which contributes to the safety and reliability of the entire system. With our experienced professionals and meticulous approach, we ensured the successful completion of the project and the satisfaction of our clients.
