400-kV-Nordeinspeisung Wien, High-voltage power line in Floridsdorf and Donaustadt districts, Vienna, Austria
The 400-kV-Nordeinspeisung Wien is a high-voltage transmission line running approximately 14 kilometers from the Bisamberg substation to the Wien-Nord substation. It combines overhead sections with underground cables to adapt to Vienna's urban environment.
The power line began operating in 2006 through Vienna Networks Company, a major upgrade to regional electricity distribution capacity. It represented an important infrastructure investment for the city during the early 2000s.
This electrical infrastructure integrates into Vienna's urban landscape through a combination of overhead lines and underground cables, reflecting local urban planning requirements.
The line runs through various urban areas where overhead sections are visible from streets and parks. Visitors should maintain safe distances from any electrical infrastructure and avoid touching or climbing on support structures.
Underground cable sections use water-filled cooling tubes that maintain performance during temperature extremes. The overhead sections employ special bundled conductor cables designed to reduce electrical discharge phenomena.
