The Sognefjord Spans are the second, third, and fourth longest spans in the world situated east of Hermansverk, Norway and are part of different powerlines. As Sognefjord Span is a deep valley the pylons of these spans are not taller than ordinary pylons. In order to avoid any too close approaches or contacts between the conductors, each is mounted on a separate pylon at the end of the span, which is built as a steel framework tower.
This span is part of the powerline between Hermansverk 61.1803°N 6.8647°W and Vikøyri 61.0806°N 6.5869°W and was built in the 1950s. It has a length of 4850 metres and was until the inauguration of Ameralik Span the longest span in the world. The span, which crosses Sognefjord in North-South direction, has 4 conductors, whereby one is for reserve. Its northern ends are at
61.175°N 6.9039°W
61.1747°N 6.9044°W
61.1747°N 6.9053°W
61.1742°N 6.9058°W
and its southern ends are at
61.1392°N 6.8536°W
61.1389°N 6.8547°W
61.1386°N 6.855°W
61.1378°N 6.855°W.
Just a few hundred meters east of Span 1, the powerline between Sogndal 61.2183°N 7.0222°W and Hove 61.07°N 6.5953°W substations crosses Sognefjord with a 4520 meters long spanning East-West direction. As Span 1 it has 4 conductors, whereby 1 is as reserve.
The locations of the towers used for this span are at its western end:
61.1356°N 6.8603°W
61.1353°N 6.8606°W
61.1347°N 6.8608°W
61.1344°N 6.8611°W
and at its eastern end:
61.1411°N 6.9442°W
61.1408°N 6.9442°W
61.1403°N 6.9433°W
61.14°N 6.9433°W
Approximately 9 kilometres east-south east of these spans, there crosses the line from Aurland1 60.8628°N 7.3011°W to Langedøla 61.4372°N 7.2456°W Sognefjord in a span with a length of 4500 metres in North-South direction. It has no reserve conductor and consists therefore of 3 ropes. Its towers are situated at its southern end at
61.1053°N 7.0647°W
61.1056°N 7.0653°W
61.1058°N 7.0661°W
and at its north end at
61.1458°N 7.0489°W
61.1458°N 7.0497°W
61.1461°N 7.0506°W
