The nearly 50-year history of successful application of AA-8000 series aluminum alloy cables is actually created under the combined action of aluminum alloy cables and aluminum alloy connectors with consistent cable performance. This kind of aluminum alloy cable application connection solution is undoubtedly scientific , Correct and very successful experience.
According to the facts, the current domestic aluminum alloy cable connection solutions are all using the wrong aluminum alloy cable + copper-aluminum transition terminal or other aluminum alloy terminals that are inconsistent with the cable performance as the connection solution. The use of connectors such as copper-aluminum transition terminals originally used for aluminum cables and aluminum alloy connectors that are inconsistent with the cable performance as a connection solution will leave fatal safety hazards, and will also wipe out the advantages and value of aluminum alloy cables.
As we all know, the application of cables, the safety problems basically lie in the connection. If the aluminum alloy cable is connected to the aluminum alloy connector, and all the defects of aluminum are still there, then why is it necessary to use the aluminum alloy cable? ? What are the advantages and value of applying Overhead AAAC Conductor 1/0 AWG 4/0 AWG?
According to the information, in addition to the fatal safety hazards of copper-aluminum transition connectors and non-conductor aluminum alloy connectors, the purity of aluminum in various brands of copper-aluminum transition terminals currently used in the market can only reach 99.5% (Note : Generally, the purity of electrical aluminum is above 99.7%), and the aluminum used in the manufacture of copper-aluminum transition terminals is still industrial aluminum with relatively poor conductivity. Therefore, the comprehensive conductivity of these copper-aluminum transition terminals can only be below 54%IACS (Note ：The conductivity of the conductor aluminum alloy is required to be above 61% IACS), which causes the electrical performance of the terminal and the aluminum alloy cable to be mismatched.
As for other aluminum alloy terminals that are inconsistent with the performance of the AA-8000 series conductor aluminum alloy, due to the physical, mechanical, electrical, and compressive creep resistance properties of the material are different from the performance of the AA-8000 conductor aluminum alloy, if such terminals are used It is self-evident that the aluminum alloy cable connection will bring safety hazards and other problems.
Therefore, choosing the correct aluminum alloy cable connection solution is the ultimate expression of the fundamental application value of aluminum alloy cable. When users purchase and use aluminum alloy cables, the primary problem is to choose the correct connection solution. For example, the UMILOY brand of American technology and military quality inherits the advanced connection technology and successful experience of the United States and other North American countries, and takes the lead in solving aluminum alloy in China. Cable connection problems, and provide the correct aluminum alloy terminal connection solutions consistent with the cable performance to the majority of UMILOY users, leading the technological development of the industry.
