Im Jahr 2014 begann ein Instandsetzungsprojekt, um die Leitung an die aktuellen Anforderungen anzupassen. Zwischen Lavorgo und Amsteg werden Isolatorenketten, Auslegespitzen, Leiterseile und das Erdseil ersetzt. Zudem ist der Austausch von zwölf Masten erforderlich, um die Mindestabstände der Leiterseile zum Boden sowie zu anderen Leitungen gemäss der aktuellen Leitungsverordnung (LeV) sicherzustellen. Der Mastersatz erfordert den Bau neuer Fundamente. Diese befinden sich in einer Höhe zwischen 1'164,9 m und 2'325,4 m über Meer und liegen teilweise in alpinem Hochgebirge. ## CPV classification Overhead line construction Construction work for electricity power lines Source Tenders Electronic Daily (EU) · Notice 775217-2025 [View official notice](https://ted.europa.eu/en/notice/775217-2025) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
