Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a carbon fiber rare earth magnesium 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. However, the high brittleness of aluminum alloys, the torsional conductors are prone to cracks, and the cracks generate heat and corrosion, which is an important cause of fires and a fatal reason that cannot be widely used in the market, limiting the application of aluminum alloy cables. [0003] The specific gravity of magnesium alloy is about two-thirds of that of aluminum, which is lighter than aluminum alloy, and the relative strength of magnesium alloy is higher than that of aluminum a...
