This paper deals with the growing need of electrical energy in aeronautical domain, which appears since several years. We focus on HVDC: over the “classical” 28 V dc, this voltage level is used and will be used more and more for supplying electrical devices. Conduction current measurements were performed on cables for different temperature and electric field values. The objective is to observe a temperature and electric field dependence of the electrical of cables' insulations. The results of current measurements were used as input for multi-physics models. Measurements demonstrate the conductivity varies very slightly with the temperature and field.
