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.
