Aluminum alloy cable conductor and manufacturing method thereof

Abstract

The invention discloses an aluminum alloy cable conductor and a manufacturing method thereof. The aluminum alloy cable conductor comprises a conductor main body with circular section, and the conductor main body comprises a central part and a peripheral part, wherein the peripheral part is sheathed outside the central part, and the inner wall of the peripheral part is adapted to the outer wall of the central part; and the peripheral part is formed by splicing a plurality of unit components along the peripheral direction. The machining method comprises the following steps of: firstly, machining raw materials into the central part and the unit components of the peripheral part; and then, stranding and splicing the central part and the unit components of the peripheral part obtained in the step (A) according to the concentric stranding rule. The seamless splicing of blocks in the aluminum alloy cable conductor is realized, and the outer surface of the aluminum alloy cable conductor forms a smooth cylinder. The mechanical properties of the aluminum alloy cable conductor are greatly improved, the corrosion resistance is also enhanced, the creep resistance is effectively improved, and the aluminum alloy cable conductor has wide applicability.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to an aluminum alloy cable conductor and a manufacturing method thereof. Background technique [0002] At present, domestic and foreign wire and cable manufacturing enterprises, the aluminum alloy cable conductors produced adopt the traditional manufacturing method-the aluminum alloy conductors need to be manufactured through drawing, annealing, stranding, and pressing processes. The resulting aluminum alloy conductors (see figure 1 ), although it is easy to bend and use during installation, but due to the low coefficient of conductor twisting and compression, there are large gaps between the conductor single wires, which not only easily encounters water penetration, causes conductor oxidation, increases conductor DC resistance, and affects the current carrying capacity of the cable performance, and it will also cause insulation discharge breakdown, which seriously affects the safe o...

[0002] At present, domestic and foreign wire and cable manufacturing enterprises, the aluminum alloy cable conductors produced adopt the traditional manufacturing method-the aluminum alloy conductors need to be manufactured through drawing, annealing, stranding, and pressing processes. The resulting aluminum alloy conductors (see figure 1 ), although it is easy to bend and use during installation, but due to the low coefficient of conductor twisting and compression, there are large gaps between the conductor single wires, which not only easily encounters water penetration, causes conductor oxidation, increases conductor DC resistance, and affects the current carrying capacity of the cable performance, and it will also cause insulation discharge breakdown, which seriously affects the safe operation of the cable; because the aluminum alloy conductor with this structure has many manufacturing processes and complex processes, it requires a large number of equipment and equipment operators, and the project investment scale is large. Moreover, the equipment needs to occupy a large area of ​​space, the equipment has high power, high energy consumption, poor equipment safety, and low overall economic efficiency. It has become increasingly unsuitable for economic and social development and needs further improvement.
