Aluminum alloy cable, copper cable, aluminum cable comparison

China is a country lacking in copper resources. With copper heavily relying on imports, people in China have long been looking forward to having a new type of conductor material to replace the scarce copper conductor material. It can be said that the idea of ​​"popularizing aluminum alloy cables with aluminum" has long been expected by the Chinese people for years. As the technology advances, it is possible to realize this. The advanced conductor aluminum alloy technology solves the defects and deficiencies of aluminum as a conductor of a cable and gradually changes people's perception of the cable industry and traditional cables and opens up the field of vision of cable industry development.

Aluminum cable for the Chinese cable industry is of extraordinary significance, which from the current situation of the development of China's wire and cable industry can illustrate that the Chinese cable industry output value of more than one trillion yuan, becoming the world's largest, accounting for more than 30% of the global market share, wire Cable industry has more than seven thousand enterprises. However, small-scale enterprises, of which the largest output value is only about 10 billion yuan, the industry 19 large-scale enterprises, accounting for only about 11% of market share. Most of the industry's small-scale enterprises, innovative ability is poor, the product can only be crazy in the low-end price war, the industry as a whole the average profit margin of only 23%. Cable industry is a pure buyer's market, which led to cable companies bad debts, serious bad debt problems, from time to time there is also a round of triangular debt crisis broke out. Most of the enterprises in the fierce competition in the market struggling.

Aluminum cables that use aluminum as an alternative to copper as conductor are self-evident for the Chinese cable market, where over 7,000 companies are fiercely competing. A recent forecast shows that in the next five to 10 years, even if China's use of aluminum alloy cables only reaches the current international standard (30%), it will rapidly become a huge one with an annual value of up to 300 billion yuan market. Right now, this is considered to be the virgin land to be developed in China's cable market. However, many people still have many misunderstandings about this virgin land. Coupled with the market a variety of aluminum cable publicity, the concept of an endless stream of diverse, true and false aluminum alloy cable products, technology, can not distinguish, and even aluminum cable technology has a different definition, chaos. But what is the real aluminum alloy cable? Aluminum alloy cable in the end how to use? What kind of aluminum alloy cable is really qualified aluminum alloy cable?

High-quality aluminum conductor rod aluminum alloy cable electrical performance, mechanical properties of the decisive factor, if not with high-quality aluminum alloy rod, after the procedure no matter how the drawing, twisted wire, cable, armor, etc. can not be changed The basic quality of its conductors. Aluminum alloy cable manufacturers must have consistent with the production of alloy AA8000 series conductor alloy formulations, with conductor aluminum alloy rod melting, continuous casting and rolling production line. That is to say they can produce conductor aluminum alloy material, if you do not have this basic ability of the enterprise, the rod come from? How to produce qualified aluminum alloy cable products? The product of this kind of enterprise is really worrying.

From the use of terms, aluminum cables and copper cables are very different. Copper cables are very familiar to everyone. They are made of a single type of metal material. After decades of application, the application technologies of copper cables and accessory accessories such as connection terminals have become very mature. Due to the aluminum alloy conductor, the aluminum alloy cable does not have the aluminum alloy copper connecting terminal and other ancillary accessory products which have the same performance with the alloy cable at present. Now the industry is the use of the original copper and aluminum transitional terminals for connecting aluminum cables and the recent so-called high conductivity microalloy copper transition terminals (which are also claimed to be aluminum alloy terminals, but in fact the concept of confusion) only for improving the terminal conductive properties. In fact these applications are extremely wrong. Aluminum alloy cable is to improve the pure aluminum cable in the physical, mechanical, compressive creep and other performance defects and deficiencies, the use of security risks found in the new conductor materials, and now the application of aluminum cables, the connection and the use of aluminum Or the so-called other non-conductive aluminum alloy which is inconsistent with the performance of the aluminum alloy cable, the defect of all aluminum or non-conductive aluminum alloy still exists and the potential safety hazard still exists. As we all know, the cable in the application of the security risks are basically connected. At present the aluminum cable in the connection because of the presence of aluminum or the so-called non-conductive aluminum alloy, aluminum cable advantages and values ​​simply can not be demonstrated and reflected, which direct use of aluminum cable What is the difference? Really correct and perfect connection solution should be used with the aluminum alloy cable performance aluminum alloy copper connection terminals as connection accessories.

Comparison of aluminum alloy cable and copper cable, look at the aluminum cable and aluminum cable. There is a saying in the market that aluminum alloy cables are better than aluminum ones, even if they are of poor quality, which is far from the truth. Does not meet the national standard aluminum alloy cable "rated voltage 0.6-1kV aluminum conductor XLPE insulated power cables, " the aluminum alloy cable is unqualified products, is the real fake and shoddy products. Perhaps many users are not clear, unqualified aluminum cable is actually not as good as aluminum cable, because the base aluminum conductor aluminum, conductor aluminum alloy is based on the core technology formula and process of adding other metal elements in aluminum alloyed by melting , Casting and processing of new materials, qualified conductor aluminum alloy electrical properties of its processing to restore the level of aluminum, physical, mechanical properties are much better than aluminum. The so-called unqualified aluminum alloy due to the manufacturer's core technology and mature production technology and professional production equipment, the final alloy formula, melting, processing technology and other reasons, the electrical performance of the aluminum alloy can not be restored to the level of aluminum, physical , Mechanical properties have not been effectively improved, improve, overall performance is not as good as aluminum. Therefore, the selection of unqualified aluminum alloy cable, might as well use aluminum cable, after all, aluminum cable unqualified aluminum cable more economical and safer.

Although the aluminum alloy cable has been hyped very hot, in fact, at present, there are only a few manufacturers that can produce qualified alloy cables in China, and there are only a few professional manufacturers who have the technology and equipment of the alloy cable intellectual property. From the cost point of view, the cost of qualified aluminum conductors and high quality electrolytic copper costs similar to the cost advantage of aluminum alloy cable copper cable is mainly due to the same weight of materials can produce different lengths of cable. The so-called unqualified alloy cable, the conductor material cost is basically the cost of aluminum materials. Unqualified alloy cable on the market, the first conductor material is unqualified, followed by manufacturers because there is no core formula technology, mature alloy cable production technology and production technology, the production of alloy cable products can not meet the requirements of qualified alloy cables, we can say that the fundamental Is not a real aluminum cable, this fake, fake products, only low sales.
