Abstract
MVCD power cable has a vital task in future commercial electric aircraft, which is power delivery. The temperature of the cable during the cable’s operation under low pressure is higher than the atmospheric pressure, which increases the cable losses. In this paper, the temperature and electric field across the insulator of the 5 kV DC Southwire cable is simulated up to 10 hours of cable operation. Furthermore, the temperature of the cable is shown with and without the presence of the chamber box. The other issue of the MVDC power cable is the cable joints and terminations. The electric field stress is high in these regions, which requires a profile study to design the terminations and joints and to increase the electric field uniformity. In this simulation study, the electric field through the gap between the electrodes is studied for the Borda and Rogowski profiles using COMSOL. The results show that the Borda profile has more area of uniform electric field than the Rogowski profile with the same thickness and dimeter. The last issue that is studied for power cables of the AEA is to combat electromagnetic interferences. The shield of the cable should combat the outer and inner EMI sources. Since the power cable is DC, most of the interferences are outer radiation from High Intensity Radiated Field and lightning. In this shielding performance study, a test and simulation are performed and studied to determine the shielding performance of the SAINT-GOBAIN copper tape at the frequency ranges of L-band and X-band.
