The project aims to undertake a detailed study on the thermal cycling effects subjected on the Dinorwig cable circuits with particular emphasis on the stop joints. The live data captured on site will enable us to model the stop joint using Finite Element Analysis. The results of this analysis should yield better understanding on the expected performance of these stop joints under differing load patterns as well as shed light on any relevant amendments regarding assumptions made in the current cable ratings model.

The desired results for this project are to improve the accuracy and understand the effects of thermal cycling on stop joints. 

This project will be successful if we increase the knowledge and understanding around the thermal cycling effects on stop joints.
