High-temperature-resistant shielding twisted-pair data cable

The utility model discloses a high-temperature-resistant shielding twisted-pair data cable, which comprises a reflective thermal insulation layer, a hollow heat-resistant layer, a heat-conducting barrier layer, a rubber waterproof layer and twisted-pair wire cores, and is characterized in that the heat-conducting barrier layer is made of waterproof cotton, the hollow heat-resistant layer is made of quartz glass, and the hollow heat-resistant layer is provided with a hollow cavity with two through ends; and the reflective coating with a certain thickness is arranged on the reflective thermal insulation layer. Compared with the prior art, the cable is provided with three cooling functional layers, and the functions of the three layers are sequentially increased from the outermost layer to the inner layer of the cable, so that the heat radiation and heat conduction effects of the cable in a high-temperature environment are greatly reduced, and the core layer of the cable is well protected; according to the schem
