On September 12, 2014, UMI Electric Company of the United States successfully developed aluminum alloy copper connecting terminals, which was the first in the industry to solve the problem of designing, installing and using aluminum alloys for power design institutes, cable manufacturers, distributors, construction parties and users. The various contradictions caused by the problem of connecting terminals during the cable completely solve the problem that the advantages and values ​​of the aluminum alloy cable cannot be truly reflected due to the mismatch of the connecting terminals. US UMI successfully developed aluminum alloy copper connecting terminal It is understood that in 2006, UMI Electric Company of the United States brought the aluminum alloy cable technology matured in the United States for nearly 50 years into China, which opened the prelude to the promotion and application of aluminum alloy cable products in the domestic market. In view of the fact that there is no special connection terminal for aluminum alloy cables in China, the foreign connection terminals cannot be applied to the domestic status due to manufacturing standards, installation methods, installation dimensions, and power maintenance systems. UMI decided to develop a special connection terminal for aluminum alloy cables for domestic use. The company's Arizona research and development team's full research and unremitting efforts finally succeeded in the development of aluminum alloy copper connection terminals. At present, the application of aluminum alloy cable is usually used for the connection of aluminum-aluminum cable for copper-aluminum transition terminal for aluminum cable and so-called micro-alloy copper transition terminal, so that the performance of aluminum in cable application due to the presence of aluminum in cable connection Defects and security risks cannot be eliminated. This connection solution makes all the advantages and values ​​of aluminum alloy cables impossible to use and manifest. In addition, the copper-aluminum transition terminal was originally used for aluminum cable, and the connection size of the terminal could not be safely matched with the size of the terminal equipment. In the construction process, the aluminum alloy cable was often connected by grinding the terminal, because the contact area was not enough, the temperature at the joint was Raising, causing a great security risk. Comprehensive strength, the only provider capable of providing the perfect connection solution It is understood that after the aluminum alloy cable enters China, the aluminum alloy conductors used by the manufacturers are different. The professional connection terminal manufacturers cannot obtain the conductor aluminum alloy rods that can match the aluminum alloy cable conductors. There are many specifications on the upper terminal, limited demand, many aluminum alloy conductors, different degrees of conductor compaction, different outer diameters, poor terminal versatility, etc. The molds and manufacturing costs of the production terminals are high, and the cost of producing the connecting terminals is fundamental. Unable to adapt to the market. It is more difficult for a typical aluminum alloy cable manufacturer to produce an aluminum alloy copper connection terminal that is consistent with the performance of its own cable. Mr. David Saeed Nikayin, CEO of UMI Electric Company of the United States, said that UMI in the United States has an aluminum alloy conductor continuous casting and rolling production line with a casting capacity of 3,807 mm, which can obtain the excellent aluminum alloy rods required for the production of aluminum alloy copper terminals, while other manufacturers can only reach 2,400 mm. The crystallization, density, strength, electrical conductivity and various technical indicators of the rod cannot meet the requirements. In addition, it is necessary to have a mechanical factory that can complete mold design, manufacture, friction welding of aluminum alloy parts of the terminals and copper, terminal shape stamping, toughness, trimming, quality inspection of terminal semi-finished products, and the like. To build a complete mechanical factory to produce connecting terminals, this kind of investment can't be done by any cable manufacturer in China, and Ubi Electric, another large UMI factory in China, provides good conditions for R&D prototype terminals. . UMI is the only provider of the aluminum cable industry with the ability to provide the perfect connection solution. First to solve four major problems in aluminum alloy cable connection applications UMI's special aluminum alloy copper connecting terminal that is consistent with the performance of the connected aluminum alloy cable will completely change the misunderstanding of the domestic aluminum alloy cable in application, and effectively solve the connection safety hazard problem for users. Specifically, the aluminum alloy copper connection terminal solves four major problems in the industry: 1. Solving the problem that the connection terminal and the aluminum alloy cable have inconsistent performance; 2. Solving the problem that the connection terminal and the terminal device do not match the size; 3. Solving the problem The inner diameter of the connecting terminal does not match the outer diameter of the aluminum alloy cable, and it is necessary to provide special crimping tools and standard construction problems. 4. Solving the contradiction between the connection terminal and the electric terminal does not need to increase the cost of transferring the bronze medal, completely avoiding the safety hazard caused by the brutal construction caused by such problems. Completely end the security risks caused by misperception UMI's perfect connection solution is not only a major breakthrough in application technology in the aluminum alloy cable industry, but also a revolution in the use of copper-aluminum transition terminals and so-called high-conductivity micro-alloy copper transition terminals in the aluminum alloy cable industry. UMI R&D, manufacturing and user-supplied special aluminum alloy copper connecting terminals that are consistent with the performance of the connected aluminum alloy cables will completely end the misunderstanding of domestic aluminum alloy cables in application, and perfectly solve the long-term troubles of aluminum. Alloy cable application parties and aluminum alloy cable industry, accessories supporting industries can not solve the problem. A new revolution in the application technology of aluminum alloy cables According to relevant reports, the Ministry of Industry and Information Technology, the Ministry of Construction, the National Energy Administration, the State Grid Corporation, the provincial construction management departments and other relevant departments have clearly stated that they will vigorously support the development of the aluminum alloy cable industry. A new forecast shows that in the next 5-10 years, even if China's aluminum alloy cable usage level only reaches the current international average level (30%), it will quickly form a huge market of up to 300 billion yuan. At present, there are more than 100 aluminum alloy cable manufacturers in China, and with the breakthrough of UMI in the connection terminal technology, the history of copper-aluminum transitional connection terminals has been completely terminated as a transitional method. A new revolution has been triggered in the aluminum alloy cable industry.
