Mabey to build National Grid's first 'T-Pylons'

British manufacturer Mabey Bridge has been awarded the first contract to construct National Grid’s new ‘T-Pylons’ - a new prototype of electricity pylons.

The firm will deliver a test line of six pylons at National Grid’s Eakring Training Academy, the first time the T-Pylons have been constructed in the UK.

The pylon has been designed by Danish architects and engineers Bystrup, following a competition organised by the Department of Energy and Climate Change, the Royal Institute of British Architects, and National Grid.

The structure is a monopole with a T-shaped cross arm, which hold the wires. It is made up of fewer than 10 major sections and is designed for simple construction. The pylon can stand at a height of 35m, which is 10m to 15m shorter than traditional lattice towers.

The T-Pylon presents an alternative to the steel lattice pylons, which dominate National Grid’s infrastructure.

Mark Coia, managing director of Mabey Bridge Energy & Marine, said: “We are extremely proud to manufacture these exciting new electricity pylon designs for National Grid.

“Mabey Bridge helped construct the traditional lattice structures when Britain’s electricity grid was first connected during the last century, and this order confirms our world leading manufacturing processes to help meet the needs of 21st energy infrastructure.”

“We look forward to working with National Grid over the coming years as the prototype of the T-Pylon design is developed further to support Britain’s electricity grid.”

David Wright, director of electricity transmission asset management for National Grid, said: “The competition was held to find a design which would meet all our safety and reliability criteria and belong to the 21st century.

“The test line at Eakring will allow us to fully rehearse how we might construct and maintain the T-pylon when in use and this contract with Mabey Bridge marks the start of that journey.”
