Abstract
The utility model relates to a copper-clad aluminium composite bus which comprises a flat aluminium core body. The utility model is characterized in that the outer part of the flat aluminum core body is coated with a coating layer made of copper material. The copper-clad aluminium composite bus of the utility model is conductor material which can not only save copper resources but also reduce product cost, and the composite bus makes full use of the separate advantages of copper and aluminum conductors, so the utility model has the advantages of good electric conductivity, light weight, high strength, easy welding, good flexibility, low cost, etc. The utility model effectively makes up for the defects of pure copper and pure aluminium buses, and the utility model can be applies to complete set of switch devices and control devices and is good for comprehensively utilizing China' s non-ferrous metal resources, improving product performance and greatly reducing the cost of bus products.
Description
(1) technical field
The utility model relates to a kind of bimetallic bus, particularly relates to a kind of conductor material one copper coated aluminium composite bus that is suitable for electric power transfer and divides adapted.
(2) background technology
Along with the paces of national economy reform progressively deeply, one is prosperous and powerful for the economic construction form, just develop towards healthy and orderly direction, all trades and professions are more and more prosperous, especially the various places urban construction has entered period like a raging fire, every construction project has driven the development of related industry, the power transmission and transformation industry has obtained very big development and promotion simultaneously, and become important component part in every engineering construction project, when big demand drives great development, energy savings, reduce cost, become the major subjects of enterprise.
China is the country of the rich aluminium of poor copper, there is a serious shortage in the supply for the copper resource, according to the interrelated data introduction, the demand of China's copper in 2000 is 1,750,000 tons, the output apparatus of copper is 1,000,000 tons, be pure importing country, and reserves China of bauxite resource ranks the first in the world, be pure exporting country, it is nearly 1st/3rd that the demand of annual China copper has, by finishing from external import.In recent years because sustainable development of economy,, cause the price of the copper product liter that wafts with the increasing of copper quantity.The power transmission and transformation industry is the rich and influential family who consumes the copper resource, and every year, only copper busbar just needed few hundred thousand tonnes of, and the bauxite resource of therefore, developing new product, make full use of China's abundant is imperative.
At present, the copper of Main Ingredients and Appearance, aluminium conductor itself exist the shortcoming that is difficult to overcome in the bus product.As: the density of pure cu conductor is big, is 8.89g/cm
3, price is high; And the conductance of fine aluminium conductor is relatively poor, mechanical strength is on the low side, flexible poor, welding performance is poor, contact resistance is big, more because of the fine aluminium conductor very easily generates the pellumina with insulation property in air, causes AC resistance to increase, ampacity reduces, and has directly limited its extensive application in the bus product.
(3) summary of the invention
The purpose of this utility model is exactly at above-mentioned problems of the prior art, and makes full use of the advantage separately of copper, aluminum, with its row machine combination, provides a kind of copper coated aluminium composite bus.
The technical scheme that adopts is:
Copper coated aluminium composite bus comprises flat-shaped aluminium core body, it is characterized in that the external packets of described flat-shaped aluminium core body is covered with the coating layer of being made by copper product.
Copper coated aluminium composite bus of the present utility model, be a kind ofly both can save the copper resource, can reduce the conductor material of product cost again, this kind composite bus has made full use of the advantage separately of copper, aluminium conductor, has good conductivity, in light weight, intensity is high, easy welding, flexible good, characteristics such as price is low, has effectively remedied fine copper, fine aluminium as the existing defective of bus.The utility model is applied to switchgear assembly and control appliance is little, helps the comprehensive utilization of China's nonferrous metal resource, helps the raising of properties of product, helps significantly reducing the cost of bus product.
(4) description of drawings
Fig. 1 is the section structure schematic diagram of a kind of embodiment of the utility model.
(5) embodiment
See also Fig. 1, copper coated aluminium composite bus of the present utility model comprises flat-shaped aluminium core body 1, and its design feature is that the external packets at flat-shaped aluminium core body 1 is covered with copper product coating layer 2.
Evidence: the mechanical performance of copper coated aluminium composite bus, each technical indicator of electric property all can satisfy the needs of all kinds of electric products, and can reach the relevant criterion requirement, and each performance index of copper coated aluminium composite bus are as shown in the table:
Claims (1)
1, copper coated aluminium composite bus comprises flat-shaped aluminium core body (1), it is characterized in that the external packets of described flat-shaped aluminium core body (1) is covered with the coating layer of being made by copper product (2).
