Abstract
By replacing metallic cross arms with insulated cross arms (ICA) the Retrofit ICAs (RICAs) solution through increased clearance to earth will allow licensees to upgrade the voltage rating of existing 275kV towers to operate at 400kV. The solution will allow an increase of the overhead line rating by over 45% with minimal construction activities and much sooner network capacity access when compared to a new built. This project will provide a pathway for the GBs first full-scale implementation of RICA technology, by mitigating technology risks and accelerating its adoption onto transmission investment schemes. The project will remove the current process, technology, and specification hurdles that have prevented licensees from adopting RICA as business as usual previously.
