Abstract

The invention discloses a heat-resistant seamless lapped aviation cable and a preparation method thereof. The heat-resistant seamless lapped aviation cable comprises a conductive core wire formed by twisting a plurality of insulating core wires, and a sheathing layer wrapping the conductive core wire; each insulating core wire comprises a conductor core and an insulating layer wrapping the conductor core; each insulating layer sequentially comprises a polytetrafluoroethylene modified turning belt, a polyimide film and a polytetrafluoroethylene sealing tape in sequence from the inside out. According to the invention, a seamless lapping and sintering technology is utilized and three-layer combination insulation is adopted, so that the heat-resistant seamless lapped aviation cable can be obtained, and favorable electrical performance and mechanical strength of the cable can be ensured. The heat-resistant seamless lapped aviation cable provided by the invention can resist the temperature ranging from minus 65 DEG C to 280 DEG C and can satisfy the requirement of being used under the high-temperature environment of 280 DEG C for a long time.
