Abstract

The invention discloses a rare earth aluminum alloy cable which comprises wire cores and an outer sheath, at least three wire cores are arranged in the outer sheath, and a carbon fiber rod is arranged in the center of the outer sheath; the carbon fiber rod is wrapped by the wire core, the wire core comprises a conductor and an insulating layer, and the conductor is wrapped by the insulating layer; the conductor is formed by stranding rare earth aluminum alloy monofilaments. The rare earth aluminum alloy monofilament comprises, by mass, 0.8%-1.3% of rare earth, 1.0%-1.5% of iron, 0.03%-0.08% of silicon, 0.02%-0.08% of copper, 0.01%-0.05% of magnesium, 0.01%-0.05% of boron, 0.01%-0.05% of zinc, 1.1%-1.8% of graphene, 1.5%-2.5% of carbon fibers, 0.9%-1.2% of aluminum-titanium-carbon, smaller than or equal to 0.1% of impurities and the balance aluminum. The invention further discloses a preparation method of the rare earth aluminum alloy cable. By the adoption of the rare earth aluminum alloy cable and the preparation method thereof, the problems that an existing aluminum alloy cable is high in brittleness and poor in conductivity can be solved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy cables, in particular to a rare earth aluminum alloy cable and a preparation method thereof. Background technique [0002] Due to the good conductivity of copper, copper is often used as a conductor in wires and cables. Due to the shortage of copper resources in my country, the price of wires and cables is relatively high; aluminum alloy cables have been applied due to their lower weight and price. Aluminum alloy cables are mostly processed with 8000 series aluminum alloy wires. The processed aluminum alloys have high brittleness, and the torsional conductors are prone to cracks, and the cracks generate heat and corrosion, which is an important cause of fires and a fatal problem that cannot be widely used in the market. The reason limits the application of aluminum alloy cables. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a rare earth aluminum al...
