The service life of aircraft cables will be affected by many factors such as high and low temperature, humidity, vibration, external liquids, etc., during the entire service cycle. The final service life is the result of the coupling and superposition of multiple factors; each material should be considered when selecting aircraft cable materials. Electrical function adaptability, physical and electromagnetic environment adaptability, structural installation adaptability, overall index adaptability, etc. during the entire service cycle; according to Aircraft cable, usually a temperature increase of 10 degrees Celsius will reduce the service life of the material by half ; When conducting fluid exposure test on Aircraft cable, a long-term test should be carried out to evaluate its impact.

When choosing aircraft cable materials or components, there are usually four aspects to consider:

Functional adaptability, that is, whether it can meet the functional requirements of the execution support system; environmental adaptability, that is, whether the selected Aircraft cable is suitable for the environmental technical conditions in the full life cycle; the structural installation adaptability, that is, whether the selected Aircraft cable can be Install and maintain under the existing technological conditions; the overall index adaptability, that is, whether the weight, cost, service life, reliability, etc. of the selected Aircraft cable meet the requirements of the whole machine level.

In an ideal situation, the Aircraft cable is reliable throughout the life of the aircraft and does not require any replacement or additional maintenance; however, this is usually not the case. Therefore, for the long-term reliability of Aircraft cable, it is important to understand the environmental impact of Aircraft cable and its related components.
