This project will investigate cable ratings in ventilated tunnels.
This project sought to develop improved tools for calculating ratings of multiple cable circuits installed in tunnels. Data (temperature, load and air flow) has been collected from UKPNs tunnels, and the results have been used to verify assumptions upon which the ratings models are built.
