Abstract: An investigation into the thermal properties of infiltrated and non-infiltrated copper windings was performed. Of particular interest was the radial thermal conductivity. The thermal conductivity measurements were performed, and the anisotropic testing module. The results of the testing were then compared to calculated values obtained by finite element modelling, as well as by a homogenization relation proposed by Hashin and Shtrikman. It was determined that there was a significant difference in radial thermal conductivity between the infiltrated and non-infiltrated samples. The experimentally determined values were also found to be in good agreement with the calculated values.
