Good Practice of the Year Award winner 2014
In 2007 it was decided to replace a single circuit line with a double circuit 400 kV line to be completed in 2014. This line now forms the backbone of the Danish transmission grid, connecting Germany to Norway and Sweden.
Strong opposition to lattice towers from the locals led to a new type of power pylon being chosen: The BYSTRUP Eagle Pylon. The intention was to create a new, calm, less intrusive and elegant power line.
The first public hearing, where different tower types and ideas were presented, was held in June 2009. The meeting gave the affected an opportunity to hear about the project and to ask questions regarding both overall issues and more local matters.
In the second public hearing in March 2010, the final design was presented and the public were asked to share their views on specific alternatives. The feedback towards the new design was overall positive.
"The locals have shown not only acceptance but even approval. The Eagle Pylon has proven that by rethinking the design and the general approach to overhead lines it is possible to get positive feedback."
- Christian Jensen, Executive Project Manager, Energinet
Eagle power pylons carry a 2x400 kV high voltage line from Kassø to Tjele in Denmark. The Eagle power pylon is designed as a shaft with arms that reach for the sky - it is an optimistic shape that sends a positive signal to the surroundings. The shaft and cross-arms are made of hot-dip galvanised steel.
The cross-arms are held in place by stainless steel wires.The pylon structure comprises a cylindrical shaft and rhomboid section cross-arms. This particular shape makes the cross-arms appear slender.The Eagle Pylon family consists of suspension, tension, and flying-angle pylons.
All family members present a close resemblance to each other due to an identical overall design. At a line terminus or underground transition, a substation and terminal tower are established.
