Sognefjord Span

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.

Span 1

This span is part of the powerline between Hermansverk 61°10′49″N 6°51′53″E and Vikøyri 61°04′50″N 6°35′13″E 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. It has 4 conductors, whereby one is for reserve. Its ends are at 61°10′31″N 6°54′14″E ( North End) respectively

61°08′21″N 6°51′13″E ; 61°08′20″N 6°51′17″E ; 61°08′19″N 6°51′18″E ; 61°08′16″N 6°51′18″E ( South End)

Span 2

Just a few hundred metres east of Span 1, the powerline from Stakaldefossen 61°26′48″N 6°00′49″E to Refsdal: 61°01′15″N 6°34′08″E crosses Sognefjord with a 4520 metres long span. As Span 1 it has 4 conductors, whereby 1 is as reserve. The Towers used for this span are at Towers at West End: 61°08′08″N 6°51′37″E ; 61°08′07″N 6°51′38″E ; 61°08′05″N 6°51′39″E ; 61°08′04″N 6°51′40″E ( West End) 61°08′28″N 6°56′39″E ; 61°08′27″N 6°56′39″E ; 61°08′25″N 6°56′36″E ; 61°08′24″N 6°56′36″E ( East End).

Span 3

Approximately 9 kilometres east-south east of these spans, there crosses the line from Aurland1 60°51′46″N 7°18′04″E to Langedøla 61°26′14″N 7°14′44″E Sognefjord in a span with a length of 4500 metres. It has no reserve conductor and consists therefore of 3 ropes. Its towers are situated at 61°6′19″N 7°03′53″E; 61°6′20″N 7°03′55″E; 61°6′21″N 7°03′58″E ( South End) respectively 61°8′45″N 7°02′56″E; 61°8′45″N 7°02′59″E; 61°8′46″N 7°03′02″E ( North End).
