Abstract :
The presented paper concerns the insulation of cables providing the link between the converters and electrical machines in aircraft. It focuses on thermal aging tests performed on cables with the analysis of the capacitance variation. The tests were conducted on samples of a three-wire shielded cable, insulated with polyimide and polytetrafluoroethylene (PTFE). This study shows that the capacitance between the conductors of a cable is correlated with the aging of its electrical insulation.
