A new method for the analysis of temperature-dependent resistances and inductances of multiconductor cable

The whole mechanical test procession, especially transmission cable is effected evidently by environment temperature fluctuation. So of particular interest in the paper is to discuss the resistance and inductance parameters of multiconductor at environment of changing temperature. A new approach with the given formulas is presented to calculate electric parameters using finite element method. And then, the temperature-dependent characteristics of resistance and inductance are obtained, which are agreed with the result obtained by energy method. The change of equivalent current density for multiconductor also highlights the parameters change when proximate effect is considered. The result is shown that the temperature-dependent parameters bring more important responses on the terminal of circuit network containing certain deviation. It is shown that. For the first time, results are shown for the lossy transmission cable with temperature-dependent parameters characteristic, which are used to quantify the main practical engineering.
