Abstract
A kind of copper cover aluminum insulated conductor, from inside to outside sequentially comprises aluminium sandwich layer, copper clad layers and insulating barrier.Its advantage combines the high-quality conductance of aluminium, low cost and the low contact resistance of copper and the functionality advantage of high chemical stability.Lightweight, price is low, electric conductivity is excellent.
Description
[technical field]
The utility model relates to insulated conductor, espespecially a kind of copper cover aluminum insulated conductor.
[background technology]
The volume conduction rate of aluminium is 64% of copper, and quality is 210% of copper than conductance, and the material price of unit mass is about 1/3 of copper, is widely used in power domain.But because the chemical property of aluminium is active, its surface generates nonconducting Al2O3 rapidly in atmosphere, and surface contacted resistance very conference causes loose contact and produces electric arc, therefore, use limitation larger, be not suitable for doing conductor material at visual plant, critical component.Although the electric conductivity of copper is stronger than aluminium, its proportion is comparatively large and price is more expensive.
[summary of the invention]
For the pluses and minuses of copper and aluminium two kinds of electric conducting materials, the purpose of this utility model is to provide a kind of lightweight, price is low, electric conductivity is excellent copper cover aluminum insulated conductor.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of copper cover aluminum insulated conductor, it is characterized in that: from inside to outside sequentially comprise aluminium sandwich layer, copper clad layers and insulating barrier.
The beneficial effects of the utility model are: combine the high-quality conductance of aluminium, low cost and the low contact resistance of copper and the functionality advantage of high chemical stability.Lightweight, price is low, electric conductivity is excellent.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is structural representation of the present utility model.
In figure: 1 be aluminium sandwich layer, 2 be copper clad layers, 3 for insulating barrier.
[embodiment]
See accompanying drawing, a kind of copper cover aluminum insulated conductor of the utility model, is characterized in that: from inside to outside sequentially comprise aluminium sandwich layer 1, copper clad layers 2 and insulating barrier 3.
In embodiment of the present utility model:
Described aluminium sandwich layer adopts high-purity aluminum steel, can ensure higher electric conductivity and the plasticity of material, and its weight significantly reduces, 1/3 of not enough fine copper wire.
Described copper clad layers covers on aluminium sandwich layer with one heart, and its thickness is not less than 0.5mm, and compare the copper conductor material of equivalent diameter, its D.C. resistance is not significantly increased, 1.35 times that only have fine copper wire; Copper clad layers is conducive to the welding of material, and particularly its brazing property is excellent.
Described insulating barrier adopts macromolecule polyester imines coating, is evenly coated in copper clad layers surface, and forming thickness after solidification is the insulating barrier of 0.2mm; Can barrier material and extraneous contact effectively, avoid material oxidation corrode and affect material property.
