The National Grid’s future is T-shaped, with pylons consisting of central steel columns and electrical cables suspended from the two arms of a giant T.

Unveiled this week for the first time, the T-shaped pylons have been designed to have less of an obvious impact on the landscape.

They also arguably have more in common with wind turbines, particularly in the appearance of their sturdy central steel columns, rather than the lattice-work seen on conventional electricity pylons.

David Wright, director of electricity transmission asset management at National Grid, said: “We developed the new style of pylon so that we could have a 21st century design to offer as we plan new transmission routes.

“The T-pylon is not a replacement for the steel lattice pylon, but it’s a new option and in some landscapes its shorter height and sleeker appearance can offer real advantages.”

At a height of 35m, the T-pylon is as much as a third shorter than the steel lattice pylon, reducing its visual impact on the horizon.

In all, there are five different types of pylon, including versions to turn corners, and end pylons to connect to substations.
