The invention discloses an aerospace high-temperature wire and the production technology of the aerospace high-temperature wire, and belongs to the technical field of cables. The aerospace high-temperature wire is characterized by being formed in the mode that an inner polyether-ether-ketone insulating layer wraps a nickel-clad copper-clad aluminum soft stranded conductor wire core in an extruded and thin-wall mode, and then a long fiber wrapping layer wraps the inner polyether-ether-ketone insulating layer in a winding and seamless mode. According to the aerospace high-temperature wire and the production technology of the aerospace high-temperature wire, the fiber wrapping layer is adopted, and therefore the cross-arc resistance, the cutting-conduction resistance and the reliability of the wire are improved. The produced wire is light in weight, small in outer diameter, high-temperature resistant, solvent resistant, good in fire resistance and good in moisture resistance.
