Problems solved by technology

[0003] At present, the aluminum alloy conductor structure is relatively simple, and they are all single-layer round conductors.
Moreover, the existing conventional aluminum alloy cable conductors are generally not annealed when used in wires and cables, and their flexibility and conductivity are poor, so their use has certain limitations.

Abstract

The invention relates to a layered aluminum alloy conductor and an annealing process thereof. The layered aluminum alloy conductor comprises an aluminum alloy inner conductor, wherein an aluminum alloy equally-divided ring layer I is arranged outside the aluminum alloy inner conductor, an aluminum alloy integral ring layer is arranged outside the aluminum alloy equally-divided ring layer I, and an aluminum alloy equally-divided ring layer II is arranged outside the aluminum alloy integral ring layer. The annealing process comprises the steps of: placing the aluminum alloy inner conductor in an annealing furnace, and subjecting the aluminum alloy inner conductor to heating, heat preserving and cooling; placing the aluminum alloy equally-divided ring layer I in the annealing furnace, and subjecting the aluminum alloy equally-divided ring layer I to heating, heat preserving and cooling; placing the aluminum alloy integral ring layer in the annealing furnace, and subjecting the aluminum alloy integral ring layer to heating, heat preserving and cooling; placing the aluminum alloy equally-divided ring layer II in the annealing furnace, and subjecting the aluminum alloy equally-divided ring layer II to heating, heat preserving and cooling; and finally, placing the aluminum alloy inner conductor, the aluminum alloy equally-divided ring layer I, the aluminum alloy integral ring layer and the aluminum alloy equally-divided ring layer II in the annealing furnace after tightly compressing and twisting. The layered aluminum alloy conductor has good extensibility, good flexibility and high conductivity, so that current is evenly distributed in the conductor structure, and effective sectional area of the conductor is enlarged.

Description

technical field [0001] The invention relates to a conductor structure and an annealing process thereof, in particular to an aluminum alloy conductor and an annealing process thereof. Background technique [0002] With the development of science and technology, high-quality, high-tech aluminum materials have been developed. In addition to the current situation of copper-poor and aluminum-rich resources in the world, the price of copper is more than three times that of aluminum. It is natural to replace copper with "aluminum". s Choice. [0003] At present, the aluminum alloy conductor structure is relatively simple, and they are all single-layer round conductors. Moreover, the existing conventional aluminum alloy cable conductors are generally not annealed when used in wires and cables, and their flexibility and conductivity are poor, so their use has certain limitations. Contents of the invention [0004] Purpose of the invention: the purpose of the present invention is ...
