the F10 flying angle suspension pylon, which can allow a turn of up to 10 degrees along the route. Taller versions can be used as ‘tension towers’ where a change of direction of 30 degrees is required. National Grid’s existing 88,000 pylons are typically 165ft high and will not be replaced by the new 120ft pylons, which are intended tobeused in theconstruction of new lines. “Our aim was to minimize visual impact and create a design that could adapt well to the English landscape,” said Brian Endahl, project manager at Bystrup, which won the project in a design competition in 2011. “We have built similar pylons in Denmark and found that the monopole structure works well in hilly areas as it requires less space and can follow the contours of the land.”

UK’s National Grid has constructed working versions of its new electrical transmission pylons.Designedby theDanisharchitecture andengineering firmBystrup, thenewpylon is a monopole T-shaped mast with two suspended diamond-shaped elements holding three cables on each side of the central pole.

Six of the pylons have been erected at the National Grid's training academy in Nottinghamshire, UK, each demonstrating a different function in the network including
