Light cable for aerospace

The utility model relates to the technical field of light cables, in particular to a light cable for aerospace, which comprises an outer protective skin and a cable, a fireproof layer is arranged on the inner wall of the outer protective skin, a metal wire braided sleeve is arranged on the inner wall of the fireproof layer, and a fixing structure is arranged on the inner wall of the metal wire braided sleeve. The inner wall of the metal wire braided sleeve is further provided with a protection structure, the protection structure comprises three air bags fixedly arranged on the inner wall of the metal wire braided sleeve, the air bags can be filled with inert gas such as helium, on one hand, the weight of the whole cable can be reduced, and on the other hand, the protection structure is arranged on the inner wall of the metal wire braided sleeve; on the other hand, the three cables are extruded at three different positions during filling, the distance between the adjacent cables is prevented from being too clo
