Abstract
The invention discloses a silver-copper-coated aluminum-magnesium-alloy low-temperature-resisting cable core includes aluminium-magnesium-alloy wire cores, copper layers and silver layers. The surfaces of the aluminum magnesium alloy wire cores are wrapped with the copper layers and the surfaces of the copper layers are wrapped with the silver layers. The volume of the copper layers accounts for 12 to 18% of the volume of the cable core. The volume of the silver layers accounts for 0.8 to 1.5% of the volume of the cable core. Each of the aluminum-magnesium-alloy wire cores comprises, by mass, 1 to 3% of Mg, 0.03 to 0.2% of Ni, 0.1 to 0.5% of rare earth and the balance being Al. Aluminum-magnesium alloy comprises carbon fibers made from polyacrylonitrile. The carbon fibers are distributed in the aluminium-magnesium-alloy wire cores continuously, uniformly and in parallel. The volume of the carbon fibers accounts for 5 to 15% of the volume of the cable core. According to the invention, the silver-copper-coated aluminum-magnesium-alloy low-temperature-resisting cable core is low in density, low in mass, high in strength and excellent in conducting performance under extremely low temperature.
