Problems solved by technology

[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 curre

Embodiment 1

[0023] Such as figure 2 As shown, an aluminum alloy cable conductor includes a conductor body 100 with a circular cross-sectional shape, and the conductor body 100 includes a central part and an outer ring part. The central portion is a circular central circle portion 110 . The central circular part 110 is formed by integral processing.

[0024] The outer ring part is sleeved outside the central part, including an inner ring part 120 and an outer ring part 130. The inner ring part 120 is sleeved outside the central circular part 110 and is adapted to the outer wall of the central circular part. The outer ring part 130 is sleeved Outside the inner ring part 120, and the inner wall of the outer ring part is adapted to the outer wall of the inner ring part; the inner ring part 120 is composed of several inner ring tile-shaped blocks 121 spliced ​​along the circumferential direction; the outer ring part 130 is composed of several outer ring tiles The shape blocks 131 are splice...

Embodiment 2

[0028] image 3 The difference between the shown aluminum alloy cable conductor and the aluminum alloy cable conductor in Embodiment 1 is that the central circular part 110 is composed of several fan-shaped blocks 111 spliced ​​together.

[0029] The manufacturing method of aluminum alloy cable conductor of the present invention, comprises the following steps:

[0030] A. The unit components of the center part and the outer circle part are obtained by pre-processing raw materials;

[0031] B. Twisting and splicing the unit assemblies of the center portion and the outer circle portion obtained in step A according to the concentric stranding rule.

[0032] C. After step B is completed, perform compression processing on the stranded splice.

[0033] The aluminum alloy cable conductor of the present invention is prefabricated into unit components (blocks), and then spliced ​​and twisted by the unit components, the seamless splicing of the blocks is realized in the aluminum alloy...

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...
