Abstract

The invention discloses a Cat5e high-temperature-resistant special cable for aerospace. The cable mainly includes three conductor cable cores, a silver-plated round copper wire braided shielding layer, a crosslinked ethylene copolymer tetrafluoroethylene insulating layer, a silver-plated copper strip armored layer and a chlorosulfonated polyolefin sheath layer. The three conductor cable cores are formed by intertwisting, each conductor cable core is internally provided with two conductor wire cores, the three conductor cable cores are wrapped by the silver-plated round copper wire braided shielding layer, the silver-plated round copper wire braided shielding layer is wrapped by the crosslinked ethylene copolymer tetrafluoroethylene insulating layer, and the crosslinked ethylene copolymer tetrafluoroethylene insulating layer is wrapped by the silver-plated copper strip armored layer. The cable is easy to lay and install, is easy to strip, coat with tin and perform terminal processing, has the advantages of high-low-temperature resistance, corrosion resistance, high flame retardance, light weight, stability and reliability and the like, is suitable for being used in special environment of aerospace, and the cable is crack-resistant and radiation-resistant.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to a category-5 super-high-temperature-resistant special cable for aerospace. Background technique [0002] The development of aerospace technology is inseparable from the support of high-performance and high-quality military wires and cables. At present, the super five signal transmission cables used in domestic electronic equipment or digital communication in local area networks use cross-linked polyethylene insulation and PVC sheath. The temperature resistance level of the cable is only 90°C, which cannot meet the requirements of high mechanical strength, high and low temperature, and chemical corrosion. For special occasions. For this reason, the development of super five high temperature resistant special cables is for the current market demand. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provi...
