This project will address rating methods employed in the design of both forced cooled and naturally ventilated cable tunnels.
The objectives of this project are to:
- Review the ratings methods used to design cable tunnels
- Assess existing operational data from cable tunnels, including Distributed
Temperature Sensor (DTS) data
- Develop a specification for a rating method for cable tunnels installations with
independent cable circuits.
