New-look pylons put through their paces

by on April 15, 2015

Construction of examples of National Grid’s new T-pylon has begun at the company’s training academy in Nottinghamshire.

The building of the training line of pylons will be the first opportunity to see the new design in the landscape.

The T-pylon was the winner of an international design competition to look for a 21st century design to carry high voltage overhead lines. The winning design from Bystrup, the Danish architects and engineering company, is 35 metres high – up to one third lower than the conventional steel lattice pylon.

A span of six of the new T-pylons will be built at the training academy. The different pylons all have a different function.

They include the standard suspension pylon that is designed to carry the cables in a straight line. Two suspension pylons will be built at Eakring.

Also in the mix is a D30 pylon which can allow for the greater pressure and weight of turning the cables at an angle of up to 30 degrees.

In addition a F10 flying angle suspension pylon which can allow a turn of up to 10 degrees – the first time such a pylon has been used in the UK- is being set up.

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.”
