According to the analysis of industry insiders, the main reason for the different prices of copper cables is that the raw materials used in the production process are different. The main raw materials of copper cables are electrolytic copper, insulation materials and sheath materials. At present, the electrolytic copper in the raw material market is about 50,000 yuan per ton, and the recovered miscellaneous copper and recycled copper are only about 40,000 yuan per ton; the price of qualified insulating materials and sheaths is 8,000 yuan per ton and 10,000 yuan per ton, and the price of defective products is A ton is only 40,000 to 5,000 yuan, and the price difference is huge. In addition, insufficient conductor cross-section, copper mixing, insufficient cable length, etc. are also important reasons for the price difference. Qualified cable products are produced according to national standards, non-standard products or defective products are not only fake and shoddy raw materials, but also the cable section and length do not meet the requirements of national standards. The reason for the different prices of aluminum alloy cable products is that the main raw materials of qualified aluminum alloy cables not only meet the chemical composition of the international AA-8000 series aluminum alloy conductor materials and the electrical performance requirements of the alloy conductor conductivity, but also meet the elongation of the aluminum alloy conductor and the flexibility of the conductor. Requirements for mechanical properties such as durability, tensile strength, and creep resistance. Qualified aluminum alloy cables have a full range of products with cross-linked polyethylene insulation and flame-retardant sheath, do not contain heavy metals such as lead and cadmium, and aluminum alloy with interlocking armor. It is understood that there are currently only two domestic manufacturers of qualified alloy cables with factories in China of American companies and one of the few domestic professional manufacturers with alloy cable intellectual property rights, technology and equipment. Qualified aluminum alloy conductors cost similarly to premium electrolytic copper. Compared with copper cables, the cost advantage of aluminum alloy cables is mainly that cables of different lengths can be produced with the same weight material. The cost of the conductor material of the so-called unqualified alloy cable is basically the cost of the aluminum material. Unqualified alloy cables on the market, first of all, the conductor material is unqualified, and secondly, the manufacturer does not have core formula technology, mature alloy cable production technology and production technology, and alloy cable products cannot meet the requirements of alloy cables, so it can be said that they are not real aluminum alloy cables. , This kind of fake and shoddy product can only be sold at a low price. Some domestic manufacturers even sell aluminum cables as alloy cables. Although this is a bad act to deceive users, at least the electrical performance of aluminum cables is better than that of fake and shoddy aluminum alloy cable products when they are used. Therefore, due to the fact that the products of alloy cables are fundamentally different and the differences are too large, there must be price differences. Through comparison, it is not difficult for consumers to see that there are differences in the sales price of finished cable products, mainly due to materials, production standards, product quality, mature production technology, production technology guarantee, whether the product is a real aluminum alloy cable, etc. Unqualified copper cables will bring potential safety hazards, and unqualified aluminum alloy cables will bring greater potential safety hazards. In fact, unqualified alloy cables are not as good as aluminum cables, because the electrical properties of unqualified alloy cables cannot reach the level of aluminum electrical properties due to technical and process reasons, and the improvement of physical and mechanical properties is even more impossible. To choose unqualified aluminum alloy cables for economic reasons, it is better to choose aluminum cables directly, because aluminum cables are more economical than unqualified aluminum alloy cables. .
