Aluminum alloy cable conductor material formula and production process
In recent years, the call for "aluminum section copper" and "aluminum substitute copper" have increased. The same is true, aluminum alloy cable from the development, production to the market have attracted a lot of attention. In addition, more and more large-scale cable manufacturers in China have begun to increase R&D costs and actively marched into the aluminum alloy cable market.
The wire and cable industry, as a heavy material light industry, has a large demand for materials and a very high demand, especially for copper materials. However, due to the high price and uneven quality of copper materials, China's wire and cable industry has been seeking a new type of alternative products for many years to reduce production costs without sacrificing product performance. Because of this,
At the end of the document, "The aluminum alloy cable products still have the following problems that need to be improved or solved: First, to further improve the product standards and testing standards of aluminum alloy cables and accessories; Second, the core technology of aluminum alloy cable conductor material formulations and manufacturing processes Currently, there are only a few companies; the third is the need to continuously accumulate experience in product applications of 10kV and above." That is to remind customers who have aluminum alloy cable conductors and aluminum alloy cable demand, look for production of core technologies such as advanced formulas and first-class production processes. Business as a supplier.
This document with milestone significance is issued, which is undoubtedly the most exciting news for professional production of aluminum alloy conductor manufacturers. Some experts believe that the formulation of the aluminum alloy conductor low voltage cable industry standard lays the foundation for product evaluation and quality supervision and is an important means and measure for regulating the product market.
Therefore, in 2014, it is a good harvest year for aluminum alloy cable R&D and production companies. With the State Grid Corporation adding aluminum alloy cables to the State Grid Corporation's 2014 new technology catalog, it means that aluminum alloy cable products are used in China's markets. This will open up a completely new situation, which means that China's wire and cable industry will take a step toward becoming bigger and stronger.
Obviously, in the western countries, aluminum alloy cable products are not new, but their application in China is undoubtedly relatively new. In particular, China's domestic wire and cable manufacturing companies have also supplemented their production of aluminum alloy cable products through independent research and development. As a blank in the industry, it is of great significance to China's wire and cable industry. During the use of aluminum alloy cable products, it has indeed demonstrated remarkable process performance. In fact, this has reached several conclusions thirty years ago. For example, the reliability of the GC company's connection to copper-clad aluminum leads to the conclusion that it can be connected in the same way as a copper wire. UL also investigated the accidents caused by poor connection of 10AWG and 12AWG aluminum wires, and copper clad aluminum does not have this problem. U.S. UL has also established copper-clad aluminum conductor standards (UL1561-2001). In addition, the British BICC company after the study of the power load on the cable and connection for up to seven years, after 10 million hours of trial and error, the results show that: Copper clad aluminum in the economic and technical competition with the copper line, and the price is stable.
The neighboring country, Japan, as a wire and cable developed country, also attaches great importance to the development and production of aluminum alloy cables. Among them, Japan Electric Wire Co., Ltd. has conducted extensive investigations and studies on whether copper clad aluminum is used as a conductive material for wire and cable. The contents of the research experiment include: (1) conductor structure for copper clad aluminum (10-15% of copper wire ratio and thickness relationship); (2) physical and mechanical properties; (3) surface characteristics, especially aluminum contact The resistance is particularly large, and copper clad aluminum is as good as copper. At the same time, its bending rigidity, repeated bending, repeated winding, etc. were tested.
In addition, Electric Wire Co., Ltd. also conducted a lot of research on the connection of connectors and wiring fixtures: (1) test on contact resistance; (2) heat conduction cycle test. Connections to copper joints: (1) Selection of size range for use; (2) Effect of secondary crimping; (3) Suitability for various connectors and connectors. After several years of practical research, it has been proved that copper clad aluminum has: (1) easy connection; (2) reliable connection; (3) light weight; (4) good winding; (5) economical, with copper wire It is also safe and reliable.
However, although developed cable countries abroad have confirmed that aluminum alloy cable products have a lot of superior performance, and domestic aluminum alloy cable product research and development and production also first tried the chopper and achieved certain results, but in a short period of time want to "It is not easy. People have to undergo a process of accepting new things. The same is true for aluminum alloy cables. This requires companies to continue to build successful cases so that more people will feel the changes brought about by new types of cables. As the saying goes, there is no rule that does not constitute a radius. Due to the lack of relevant industry standards for domestic aluminum conductor cables, the market is not standardized. China's cable industry standards lags behind, and there are still some gaps between European and other countries' standard systems.
The lack of a unified national standard has become the biggest obstacle to restricting the promotion of aluminum alloy cables. If this problem can be solved, aluminum alloy cable will get greater development in China. China's aluminum alloy cables do not have corresponding industry standards or national standards, and there are no standards for design, procurement, use, and acceptance. Aluminum alloy cables have been widely used and promoted in China for several years, and their market share and application area have increased year by year. The attitude of users to aluminum alloy cables has experienced conflicting, questioning, understanding, and accepting several stages.
However, in 2014, it was undoubtedly a year of harvest for aluminum alloy cable R&D and production companies. The main reason was that the National Grid Corporation’s (2014) No. 880 company document (external documents) had been issued. The document was titled “State Grid Corporation of China. Document: Answer to the No. 9887 Recommendation of the Second Session of the 12th National People's Congress, which affirms the importance of the "copper to aluminum substitute" in the wire and cable industry, and points out that aluminum alloy cables with voltage ratings of 10kV and 1kV are already The application of the national cable company's affiliated unit has been provided with the corresponding material number for filing, and aluminum alloy cables have been incorporated into the 2014 new version of the State Grid Corporation of China.
