The invention discloses a high-temperature-resistant cable for the aerospace, which comprises a cable body, and is characterized in that the cable body comprises four cables, the four cables are formed by twisting in a spiral point contact manner, the outer surfaces of the four cables are wound with a mica tape wrapping layer, and the outer surface of a conductor is wrapped with a layer of polyimide composite tape, so that the transmission of electric signals is not affected, and meanwhile, the cable has good heat resistance, good mechanical properties, thermo-oxidative aging resistance and noobvious melting point. In addition, a glass fiber braid layer can well protect the conductor and play a role in heat insulation, and the glass fibers are used as a protective layer. The surface of the protective layer is coated with the high-temperature-resistant emulsion, so that good sealing performance can be provided, and heat resistance can be improved at the same time.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a high-temperature-resistant cable for aerospace. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several wires or groups of wires. With the advancement of life and technology, cables need to be laid in various places, even in the aerospace field. Due to the national aviation A large number of independent research and development and production of aerospace electronic equipment has created a demand for localized production of aerospace high-temperature-resistant cables, and at the same time put forward higher requirements for high-temperature resistance, electrical and environmental resistance for cables. [0003] At present, the commonly used high-temperature-resistant cables generally use high-temperature plastic insulating material combination sheaths, and the ability to withstand high temperatures can only be aro...
