Abstract
The invention relates to a high-temperature resistant super-soft wire cable with rated voltage of 250V for aerospace, which is characterized in that a conductor of twisting multi-strand silver plating brass wires is adopted; the diameter of a single wire of the multi-strand silver plating brass wires is 0.051mm; an insulating layer is arranged on the periphery of the conductor; the thinnest insulating thickness is 0.16mm; and a sheath layer is arranged on the periphery of the insulating layer. The preparation technology of the wire cable comprises the steps of: twisting the silver plating brass wires for making the conductor by using a wire cable bundle twisting machine; extruding the insulating layer by using high-temperature extruder equipment; twisting insulating wire cores together by using a cable making machine; adopting small pitch for multi-strand twisting; and extruding a sheath by using the high-temperature extruder equipment. The wire cable has the advantages of softness, high-temperature resistant property, anti-oil property, anti-aging property, impact resistant property, cracking resistant property and softness under a low-temperature condition, and is suitable for special environments of aerospace, electronic chariots and the like for equipment control and signal transmission.
