Problems solved by technology

[0002] In the prior art, the conductive bars used in the field of power distribution are mostly made of pure copper materials. The power distribution equipment using pure copper conductive bars has the disadvantages of heavy weight and inconvenient installation and transportation. More importantly, in recent years, the international The price of ferrous metals in the market is soaring, and the price of copper is also rising, which will undoubtedly increase the manufacturing cost of power distribution equipment. People's eyes are turning to seek alternatives to pure copper conductive bars.

Embodiment Construction

[0023] Referring to the drawings, a conductive row includes an aluminum core 1 and a copper layer 2 coated on the outside of the aluminum core 1, and the copper layer 2 is fully coated on the outside of the aluminum core 1 , a closed circle is formed on the cross section of the conductive row, and the copper layer 2 has no seams.

[0024] The cross-section of the conductive row is rectangular, and the cross-sectional area of ​​the copper layer 2 accounts for 13-21% of the cross-sectional area of ​​the conductive row, and the best embodiment is 15%. Experiments show that the volume of the copper layer The conductivity of the copper-clad aluminum busbar with a ratio of 15% is 85% of that of pure copper compared with pure copper busbar, and the density of copper-clad aluminum busbar is only 37%-40% of that of pure copper busbar. The length ratio of copper-clad aluminum row to pure copper row is 2.0-2.5.

[0025] A method of manufacturing the above conductive row, comprising the ...

Abstract

The invention relates to a conducting bar and a manufacturing method thereof. The conducting bar comprises an aluminum core and a copper layer covering the aluminum core. The copper layer is closed around the aluminum core. The cross section of the conducting bar is rectangular; the area of the cross section of the copper layer accounts for 13 to 21 percent of the area of the cross section of the conducting bar. The conducting bar with copper covering aluminum can reach various parameter standards of the conducting bar. The invention further provides a new conducting material. By comparing the conducting bar with a fine copper conducting bar with equal cross section area, the price is low; the weight is light; and the conducting bar provided by the invention can be installed and transported conveniently, and is favorable for the environmental protection.

Description

technical field [0001] The invention belongs to the field of power supply and distribution. Background technique [0002] In the prior art, the conductive bars used in the field of power distribution are mostly made of pure copper materials. The power distribution equipment using pure copper conductive bars has the disadvantages of heavy weight and inconvenient installation and transportation. More importantly, in recent years, the international The price of ferrous metals in the market is constantly soaring, and the price of copper is also rising, which will undoubtedly increase the manufacturing cost of power distribution equipment, and people's attention is turning to seek alternatives to pure copper conductive bars. Contents of the invention [0003] The purpose of the present invention is to find a substitute for the pure copper conductive row, to provide a conductive row with little difference in performance from the pure copper conductive row, but with low price and...
