Abstract: The electrical, thermal, mechanical, chemical, and space environment(including radiation, low gravity and low pressure) performance requirements of cables for different aerospace environments were introduced, and the corresponding aerospace environment(include the cabin environment and the outside environment) were analyzed, different cables used inside and outside the cabin should meet different requirements for the aerospace environment, the important feature of the cable used in the cabin is that it does not produce harmful gases to people and equipment. The performance requirements of cables for different aerospace environments are obtained, and suggestions for the selection of cables for different aerospace environments are put forward.
