What’s a T-pylon and how do we build them?

Animation plus footage from construction at our test site in Nottinghamshire

The Hinkley Connection will be 57 km long – made up of 48.5 km of overhead line and 8.5 km of underground cable through the Mendip Hills Area of Outstanding Natural Beauty (AONB).

We’re using T-pylons for most of the overhead line sections – the first new design for pylons in this country for almost a century. It has a single pole and T-shaped cross arms which hold the wires in a diamond ‘earring’ shape. It is around 35 metres high; about a third shorter than traditional 400,000 volt steel lattice pylons. It also has a smaller footprint and will use less land

The video and animation below shows how we are going to build them or you can download our T-pylon leaflet to find out more.
