The scope of this project is to design and build prototype Insulated Cross Arms, and conduct mechanical and electrical trials.
Design and build prototypes for the uprating of 132KV tower lines
Install protoype 132KV models in a harsh weather environment test area - The Lecht
Install current L3 prototype models in a coastal trial site to evaluate the effects of salt and other pollutants on the insulation – St Fergus
Installing and monitoring the Lecht and St Fergus trials for the Insulated Cross Arms
