Analysis of the Cost-effectiveness of Aluminum Alloy Cable Shaking Copper Cable Market

From the large-scale transmission projects to the construction of small factories and public facilities, copper cables have always been considered by construction workers. China's annual consumption of copper for the production of cables accounts for more than 60 of the total domestic copper consumption. As more and more companies infiltrate into cable production, the dependence of the cable industry on copper imports continues to increase, and manufacturing and construction costs increase. In developed regions such as Europe and America, aluminum alloy cables with higher cost performance and superior electrical performance have been successfully used for more than 40 years. Many churches, hospitals, and government agencies use this new type of cable as the most copper cable when purchasing cables. Good alternatives, some domestic new construction also began to try to use aluminum alloy cables. Aluminum alloy cable cost performance beyond the copper cable China's aluminum alloy cable market is developing slowly, the most important reason is the backward production technology and technology, in the previous period, can not make the aluminum alloy cable to achieve the same electrical performance with the copper cable. After rapid development in recent years, the domestic R&D strength and production capacity of cable companies have been greatly improved. After many years of technological breakthroughs, the company represented by Jinshenhuier Cable Co., Ltd. achieved a number of breakthroughs in aluminum alloy cables and passed the authority certification of multiple departments in the country. Through the addition of rare earth, iron and other materials in pure aluminum, through the latest compaction and twisting process, the cross-sectional area of ​​the aluminum alloy cable is equal to or even better than the traditional copper cable, with the cross-sectional area only increased by 1.1 times.

In the face of different use environments and construction requirements, Jin Yee-Hair has also developed a number of targeted products: ZC-TC90(-40), ZB-ACWU90(-40), and ZA-AC90(-40) in order to achieve Safe, stable, long-lasting power transmission. Compared with copper cables, the cost-effectiveness of the Jinyinhuier aluminum alloy cable is mainly reflected in three aspects. The first is the price advantage. The price of aluminum raw materials is much lower than that of copper. Even if precious materials such as rare earths are added in the production process, the total cost is still lower than that of copper cables. For large-scale projects, it will save a huge amount of cable procurement costs; the second is the use of the same construction site. According to the provisions of GB/T 12706 for the bending radius of copper cables installed, the bending radius of copper cables is 10-20 times the cable diameter, the minimum bending radius of aluminum alloy cables is 7 times the cable diameter, and aluminum alloy cables can be installed in different installation environments. Avoid more losses.

At the same time, the weight of the aluminum alloy cable is lighter, and the bridge frame can be reduced in the large-span installation, which is easier to install and the installation cost is lower. The third is the long service life. Aluminum alloy cable body will immediately form a dense oxide layer in contact with air, this oxide layer is particularly resistant to various forms of corrosion, coupled with cable outsourcing silane cross-linked polyethylene insulation material, cable itself The service life is longer than copper cables by more than 10 years. The new project favored aluminum alloy cables. The reporter discovered after investigation that aluminum alloy cables can be seen in new projects such as factory buildings, transportation, public facilities, and power supply projects throughout the country.

As the aluminum alloy cable is matched with the connection terminal of the copper cable, the connection with the original cable can be easily realized. The resilience of the aluminum alloy cable is 40 lower than that of the copper cable, which is more conducive to the tightness of the terminal connection joint and the stability of the connection under the long-term use condition. The high cost performance of aluminum alloy cables is the biggest reason why it has won the favor of new construction projects. The construction personnel at a construction site told the reporter that our factory was called by the corresponding government to move out of the urban area. The new factory was much larger than before, and more funds were invested. The choice of aluminum alloy cable is to ensure the safety of production while reducing procurement costs. It now appears that not only has 40 been saved on the purchase of cables, but also the construction has been very quick. If you look at this distance, according to the previous plan, you will build 5 bridges. Now that only 3 of them are built, it will be enough. Aluminum cables are very light. Some of the projects started with new types of aluminum alloy cables. The reporter saw in the new office building of an administrative unit that the main building still used copper cables, and the lighting outside the building chose a corrosion-resistant aluminum alloy cable. No difference can be seen, it is very stable, but the price of aluminum alloy cable is lower. An engineer in charge of electricity supply told reporters. With the continuous development of a conservation-minded society, Jindu Huier and other aluminum alloy cables will go into more new construction projects. While gradually replacing copper cable applications, they will also prompt the rationalization of copper cable prices, thus stimulating the entire cable industry. The industry ushered in new opportunities for rapid development.
