Analysis and Experimental Study on Influence Factors of Spacecraft Power Cable Temperature

The design of the power cables is related to the safety of the satellite power supply. High temperature of the power cables may lead to short circuit, cable transmission performance degradation, cable damage or other risks. The temperature of the power cables is difficult to get accurate result by theoretical calculation and simulation analysis. In this paper, cable temperature rise tests under different constraints are carried out, and the influence of the factors on cable temperature changes is analyzed. Based on the effect of various factors on cable temperature rise, the design methods and treatment measures of the power cables in practical application are summarized. The results can provide a reference to the design of the spacecraft power cables.
