Domestic wire and cable industry for aluminum alloy cables have been very familiar with, and even buyers and users of aluminum alloy cable under the strong publicity, the aluminum alloy cables have further understanding and understanding. However, we found that about Aluminum Alloy cable propaganda show "one-sided" situation, almost all related to Aluminum Alloy cable products, the superiority of the best praise Aluminum Alloy products, but ignore the Aluminum Alloy cable products also exist defects or not enough. Therefore, the objective and correct understanding and understanding of aluminum alloy cable products, for procurement units, is the first to do.

　　Aluminum Alloy cable technology is not native products, in fact, in 2006, Aluminum Alloy cable technology and products by the company to the Chinese market, but the ability to follow Chinese is amazing, the first of the world, so in a very short period of time, the wire and cable manufacturers Chinese quickly mastered the basic Aluminum Alloy cable technology, which plays Aluminum Alloy cable card, publicity around Aluminum Alloy cable products, in the promotion process is a man-made "deification" of suspects. According to a prediction data released by the cable industry before, even in the next five to ten years, the level of China's aluminum alloy cable technology can only reach today's international general level.

　　So why domestic cable manufacturers are keen to show even "deification" Aluminum Alloy cable? The main reason is that Chinese Aluminum Alloy cable market is great, every year can reach 300 billion yuan, plus this is a China cable market to be developed so that virgin land, it is a real sense blue ocean. In the international society, development of technology and products Aluminum Alloy cable is relatively long, Aluminum Alloy cable originated in the North American market, in twentieth Century 60s and 70s, the southern United States Aluminum Alloy cable cable as the earliest inventor, began to vigorously promote the Aluminum Alloy cable in the North American market, as with Aluminum Alloy instead of copper or aluminum as cable conductor.

　　Aluminum alloy cables are mainly used in airports, military bases, office buildings, residential buildings, hotels, supermarkets, colleges, stadiums, hospitals, factories and other construction projects. The United States has successfully applied aluminum alloy cables for more than 50 years and has never had any safety incidents. As far as the actual performance is concerned, the aluminum alloy cable does not improve the conductivity of pure aluminum cable, but its bending, compression, creep and corrosion resistance have greatly improved the physical and mechanical properties. Compared to copper cables, Aluminum Alloy cable on the weight, price and installation works have advantages of copper There is nothing comparable to this. In other words, the aluminum alloy cable is more economical and has a wide range of applications under the premise of the same electrical performance and better mechanical properties.

　　Although the advantages of aluminum cable products are obvious and very attractive, especially in terms of price, the cost of manufacturing copper cables is much lower than that of copper core cables. However, although this is apparent on the surface, but if in-depth analysis, we will see that the development and production of aluminum alloy cable products are not as low as we expected. For example, aluminum alloy cables are of high technical content and large investment in production equipment. They need mature materials, formulations, production techniques and talents. In order to ensure the quality of alloy material, the production of conductor aluminum alloy material needs patent formula and needs self melting and casting rolling. Cable production also requires multi-channel refining and other production processes, requiring special technology, mature technology, specialized production and management personnel, special production equipment, etc., and it is possible to produce qualified alloy cable products. Industry threshold is high, not professional, do not have the strength and mature production conditions of manufacturers difficult to participate.

　　Secondly, all copper cables are processed from conductors, and because copper conductor is a single metal material, the quality of the material is easier to control. But because of the different conductor materials, the production equipment, production technology and process of aluminum alloy cable are very different from those of traditional copper cable. The equipment and technology of conductor alloy smelting, conductor alloy material continuous casting and continuous rolling should be put into practice. The special equipment for cable production of aluminium alloy cable, specialized technology and special production process. Aluminum alloy cable production, quality control is from the alloy material smelting began, in equipment support, strict process, technical control, casting rolling, forming qualified conductor aluminum alloy rod. The quality assurance of aluminum alloy bar is the prerequisite for the quality assurance of aluminum alloy cable. If we can't produce the aluminum alloy rod by ourselves, the quality of the bar can not be controlled at all, and the quality of the aluminum alloy cable can not be mentioned. Compared with the traditional cable production, the equipment, technology and process requirements for the production of alloy cables are higher and more advanced. At present, the domestic non professional aluminum alloy cable manufacturers still do not have these conditions and capabilities.

　　In addition, the domestic performance is very obvious, China's aluminum alloy cable products in the application, there are still some of the most basic cognitive errors. It is also from this point, the side reflects the Chinese aluminum alloy cable technology and products have yet to be promoted. For example, copper cable is made of single material for manufacturing metal and, after decades of application technology, and copper connecting terminal accessory has been very mature. Aluminum alloy cable because of its conductor for aluminum alloy materials, there is no domestic alloy alloy cable consistent with the performance of aluminum alloy, copper terminals and other ancillary accessories. Now the industry is using the original transition for aluminium cable terminal connection and the recent so-called only in order to improve the conductivity property of the terminal micro alloy copper transition terminal (also claimed that foreign Aluminum Alloy terminal, but the concept of confusion), in fact these application case is wrong.

　　Aluminum Alloy cable is pure aluminum cable in order to improve the defects and deficiencies in the physical and mechanical properties, compressive creep, new conductive material and invention of the existence of security risks in the use, application of Aluminum Alloy cable now, in connection with aluminum or Aluminum Alloy cable performance inconsistent Aluminum Alloy as other so-called non conductor the connection, then the defect of all aluminum conductor or non Aluminum Alloy still exist, security risks still exist. As we all know, the safety of cables in application is basically connected. At present Aluminum Alloy cable on the connection because of aluminum or so-called non conductor Aluminum Alloy exists, Aluminum Alloy cable advantage and value cannot be embodied, and this directly using aluminum cable hardly any difference
