Overhead line crossarms. The use of an insulating crossarm potentially allows the upgrading of an L3 275 kV tower to operate at 400 kV or other tower types to raise their voltage level and the elimination of the insulator strings.
The project evolves from previous work carried out between Manchester University, National Grid and SHETL.

Previous work (IFIT_2009_01) has focused on the construction of environmental test areas, one at high altitude and the other at a coastal location. This project is focussed on the creation of a live network trial.
