Problems solved by technology

[0012] In the production process of aluminum conductors, the aluminum monofilament will be mechanically drawn and shaped many times, which will easily cause mechanical damage on the surface, hardening of the conductor, and increase in conductor resistance.
Moreover, the production efficiency of aluminum conductors is low, energy consumption is high, and quality is difficult to control

Abstract

The present invention discloses an aluminum conductor automobile wire and a preparation method thereof. The aluminum conductor automobile wire comprises: a body made of aluminum and having a section with a filled rectangle, the section length being 10 to 30 mm, the section width being 0.8 to 5.1 mm; and an insulating layer coating the outer surface of the body and having a section with a hollow rectangle, the section length being 11.5 to 34 mm, the section width being 2.3 to 9.1 mm. According to the aluminum conductor automobile wire in the embodiment of the invention, compared with an aluminum conductor with stranded structure and same rated current carrying capacity, the aluminum conductor automobile wire is decreased in aluminum products by 3% to 7%, the elongation at break of the aluminum conductor automobile wire is higher than that of a copper stranded conductor, the aluminum conductor wire with the rectangular section is compact in structure, and the size thereof is 10% to 20% smaller than the size of the round stranded aluminum conductor wire; moreover, the aluminum conductor automobile wire is very easy to be putted in an automobile, with saving space.

Description

technical field [0001] The invention relates to the technical field of automobile electric wires, in particular to an aluminum conductor automobile electric wire and a preparation method thereof. Background technique [0002] At present, the automotive industry has begun to pay attention to the use of aluminum conductors. is based on: [0003] ——The price of copper is soaring, and the price difference between copper and aluminum is getting bigger and bigger; [0004] ——The demand for energy-saving and environmental protection of automobiles is getting higher and higher, and the requirements for lightweight automobiles are becoming increasingly urgent. [0005] Because the conductivity of copper conductors is better than that of aluminum conductors, and the surface of aluminum conductors with circular stranded structure is easy to oxidize, the cleanliness is poor, and the production efficiency is low, which affects the processing of automotive wiring harnesses and the relia...
