Abstract
The invention discloses a copper wire with an insulating layer and a manufacture method thereof. The copper wire comprises a copper core, a pure aluminum layer and an aluminum oxide layer, wherein the pure aluminum layer is compounded to the outer surface of the copper core through a metal composite technology, and the aluminum oxide layer which is prepared through hard anode oxidation treatment is arranged on the outer surface of the pure aluminum layer. In the method, the pure aluminum layer is compounded to the outer surface of the copper core through an extrusion-drawing method metal composite technology and is an auxiliary layer added in order to prepare the aluminum oxide layer, and the hard anode oxidation treatment is carried out on the outer surface of the pure aluminum layer so as to form the aluminum oxide layer. Because the copper wire manufactured by using the method is adopted, the aluminum oxide layer is arranged on the outer surface of the copper wire; the copper wire belongs to ceramic materials per se and has the advantages of high temperature resistance and insulation, therefore, when used at the temperature of below 400 DEG C, the copper wire can also keep favorable insulating performance, is safe to use and has the temperature exceeding a copper wire canned by conventional plastics by more than one time.
Description
Technical field
The present invention relates to a kind of transmission of electricity copper conductor, especially a kind of copper conductor and manufacture method thereof with insulating barrier.
Background technology
At present, common copper transmission pressure all is to use the outer wrap of plastics as insulating barrier, can satisfy the electric insulation requirement under the general temperature conditions.But when the environment for use temperature reaches between 150～200 ℃ or electric wire self temperature reaches between 150～200 ℃, the forfeiture insulating effect causes short circuit or fire to the insulating barrier of plastics matter easily with regard to beginning softening.
Summary of the invention
For solving the problems referred to above that prior art exists, the objective of the invention is to propose a kind of copper conductor with insulating barrier and the manufacture method thereof that can under the higher temperature environment, use.
To achieve these goals, technical scheme of the present invention is as follows: a kind of copper conductor with insulating barrier is made up of copper core, aluminum layer and alumina layer, described aluminum layer is compound to the outer surface of copper core by the metal composite technology, has one deck to handle through hard anodizing and the alumina layer that makes at the outer surface of aluminum layer.
Alumina layer thickness of the present invention is 0.1～0.2mm.
The thickness of aluminum layer of the present invention is slightly larger than alumina layer.
A kind of manufacture method with copper conductor of insulating barrier may further comprise the steps:
A, the copper wicking surface is handled, removed the greasy dirt and the CuO film of copper wicking surface;
B, handle with the aluminum layer surface, remove the greasy dirt and the aluminum oxide film on aluminum layer surface compound;
C, by extruding-hubbing metal composite technology aluminum layer is compound to the outer surface of copper core, the auxiliary layer that adds as the preparation alumina layer;
D, the outer surface of aluminum layer is carried out hard anodizing handle, form alumina layer.
The described hard anodizing of step D of the present invention is handled and is adopted the sulfuric acid type anodizing solution, oxidizing temperature-3～-6 ℃, and current density is 2～2.5A/dm
