This dissertation presents a dynamic thermal circuit to model trefoil power cables of different sizes (and/or loads) installed in non-forced-ventilated tunnels. This is a step forward from the available calculations that only treat identical and equally loaded cables in steady-state. The circuit model includes heat transfer into all tunnel wall surfaces. Results demonstrate that conductor temperature is independent of tunnel size beyond three cable diameters for engineering purposes. This dissertation also demonstrates that for non-forced-ventilatedtunnels, different from cables installed in free air, the induced heating from cables installed below other cables is negligible for all practical purposes. The dynamic thermal circuit is proposed to model all cable dynamics and it is validated with numerous finite element transient simulations. All results are within small percent differences. Transient ratings for general cable arrangements installed in non-forced-ventilatedtunnels can be computed with the methods proposed in this research work.
