But technological advances to China wire and cable industry has brought an excellent opportunity that began in 2006 originated in the United States of a new type of cable conductor materials technology, namely technology and aluminum conductor aluminum cable products, this technology by two US companies were brought into the Chinese market. After that, Chinese aluminum cable market has been detonated. Forecast shows that the next few years, even though the level of China's use of aluminum cable, just to reach the current level of international general (30%), that will quickly form a year up to 300 billion yuan huge market. There is no doubt that such a huge market and immediately attracted the attention of many companies in the industry.
After the aluminum cable into China, have not been able to open a broad market, an important reason why the actual performance, although aluminum cable did not improve the conductivity of aluminum cable, but the cable is bent aluminum, compressive creep and corrosion and other physical and mechanical properties has increased greatly. Compared to copper cables, aluminum cable in terms of weight, price and installation works are incomparable superiority with copper. Other words Popular's words, that is, under the premise of the same electrical performance and better mechanical properties of aluminum cable is more economical, and a wide range of applications.
Such a huge market, many companies want to meddle in the wire and cable, wire and cable, but small and medium enterprises as the main component of China's cable industry has not been able to complete the expansion of this market, which is due to the high content of aluminum cable technology, production equipment investment, need to have a mature material formulations, production technology and talents, whether large or small businesses, temporarily do not have this condition. Aluminum alloy conductor production needs patented formula, to be their own smelting and casting, in order to ensure the quality of the alloy material. Multi-channel cable production needs tough refining and other production process requirements, need expertise, sophisticated technology, specialized production and management personnel, dedicated production equipment and so complete, it may produce qualified alloy cable products. High barriers to entry, not professional, do not have the strength and maturity of the factory production conditions difficult to participate.
As a new technology, manufacturing expertise and strong aluminum cable, equipment requirements, technology, process difficult. All copper cable conductors are processed from the beginning, because the copper conductor is a single metal material, the material quality is easier to control. However, because aluminum cable conductors of different materials, production equipment, production technology and production processes with traditional copper cable is very different. Need to invest alloy melting conductor, conductor alloy casting and rolling equipment, technology, aluminum cable and cable production equipment, expertise, specializing in the production process. Aluminum cable production, quality control from the start melting alloys, after casting equipment support under strict process control technology, the formation of qualified conductor aluminum rods. Aluminum Rod, quality assurance is to ensure the quality of aluminum cable premise. If you can not produce their own conductor aluminum rods, the rods can not put quality control, the production of aluminum cable quality is out of the question. Compared with the traditional cable production, alloy cable manufacturing equipment, technology, technology requirements are higher, more advanced. At present, non-professional aluminum cable manufacturer does not have these conditions and capabilities.
The greatest advantage of aluminum cable is cost savings. As we all know, the price of copper cables are quite different, which is mainly due to the raw materials used in the production process caused by different. The main raw material production of copper is copper cables, insulation and sheathing materials. Copper per ton of raw materials currently on the market at around $ 50,000, and the recycling of scrap copper, recycled copper per ton of only four million; qualified insulation and sheathing materials price per ton in eight or ten thousand, and price defective products only 4000-5000 yuan per ton, the difference and the poor. In addition, the conductor cross-section is not enough, the quality of copper doping, lack of cable length, etc., also contributed to an important reason for the price difference. Cable qualified according to national standards of production, rather than standard products or raw materials are not defective and shoddy goods, cable section and length do not meet national standards. Aluminum cable prices are different, because the qualified aluminum cable is in addition to the main raw material in compliance with international AA-8000 series aluminum alloy conductor chemical composition and electrical conductivity of the conductor performance requirements, but also at the same time meet the aluminum conductor elongation, conductor flexibility, tensile strength, creep resistance and other mechanical performance requirements. Qualified aluminum cable with a full range of products are various levels of flame-retardant XLPE insulation and flame retardant sheath, the sheath does not contain lead, cadmium and other heavy metals, aluminum interlocking armor and so on. Although a lot of publicity aluminum cable, concept deeply rooted, but China is not able to produce more. It is understood that the country can produce qualified alloy cable manufacturers, only two US companies and factories in China, there are a few very small number of intellectual property rights alloy cable technology and equipment of the professional manufacturers.
At cost price, aluminum cable and copper cable does not have too many advantages compared to, aluminum cable than copper cable cost advantage lies in the same weight materials can produce different cable lengths. There are many on the market, such as the failure of the alloy cables that failed first is the conductive material on the failure, followed by the manufacturer because they do not have the core formulation technology, sophisticated alloy cable production technology and production technology, production of alloy cable products can not be achieved qualified alloy cable requirements, you can say that is simply not true of aluminum cable, this shoddy, counterfeit products, only low-cost sales.
