Description

technical field [0001] The invention relates to the technical field of power cable materials, in particular to an isolated rare earth aluminum alloy cable and a preparation method thereof. Background technique [0002] Because copper is expensive and relatively heavy, aluminum materials are currently used to replace copper for the conductive cores of insulated wires and cables, and most of them are made of hard aluminum wires. With the widening of the use of aluminum alloy materials, according to the use in different regions, It can be used in coal mine wires, communication wires, high-speed rail wires, automobile wires, and electromagnetic wires. According to different usage scenarios, different performances are required to meet the needs of use. [0003] General aluminum alloy wires need good isolation in some harsh environments, otherwise they are easy to be damaged, thus reducing the service life. Contents of the invention [0004] Aiming at the deficiencies of the pr...
