List of spans
The following is a list of spans, either used for overhead line crossings of rivers, sea straits or valleys, as antenna or for aerial tramways.
Powerline spans in flat areas with high pylons
At these spans the sag of the conductors is less than the height of the pylonsPowerline spans in mountainous areas requiring shorter pylons
At these spans, the pylons are situated on the tops of mountains, so the topography determines the height of the lines. Because of this it is possible that the span pylons can be lower than sag of the conductors.| Crossing | Country | Location | Height of pylons | Span width, leaning straight line | Span width, horizontal measurement | Height of conductors over ground | Year of inauguration | Notes |
