Neher-McGrath Thermal Resistance Coef 2

[dik]

Does anyone have a source for Thermal Resistance Coefficients for Neher-McGrath related to soil types and degrees of saturation?

Here is a partial list of thermal resistivity of common materials and other references that I have used for underground cable ampacity calculation. I hope you find it useful for your applications.

Thank you very much... appreciated.

cuky - you are the man as usual. Do you have a website with all this stuff you've collected?

Hello Pete- I been working for a while collecting soil thermal resistivity data from several sources including websites, books and other technical publications. Below are some website links that I hope you find useful.
