Do you know the advantages of aluminum alloy cable?(2)

Dec. 01, 2016

I will tell you some advantages of aluminum alloy cable as followings:

Self-weight bearing capacity

Aluminum alloy to improve the tensile strength of aluminum, aluminum alloy cable can support the weight of 4,000 meters in length, copper cable can only support 2750 meters. This advantage in large-span buildings (such as sports venues) wiring is particularly prominent.

Anti-corrosion performance

The inherent corrosion resistance of aluminum comes from the formation of a thin, strong oxide layer when the aluminum surface is in contact with air, which is particularly resistant to various forms of corrosion. The addition of rare earth elements in the alloy can further improve the corrosion resistance of aluminum alloys, especially electrochemical corrosion. Aluminum can withstand the characteristics of harsh environments so that it is widely used in trays within the cable conductor, and many industrial components and containers. Corrosion is usually associated with the connection of different metals in a wet environment, and appropriate protection measures can be used to prevent corrosion, such as the use of lubricants, antioxidants and protective coatings. Alkaline soils and certain types of acidic soils are more corrosive to aluminum, so buried aluminum conductors should be protected with an insulating layer or molded jacket. In sulfur-containing environments such as railway tunnels and the like, the corrosion resistance of aluminum alloys is much better than that of copper.


Aluminum alloy has a good bending performance, its unique alloy formula, processing technology, so that a substantial increase in flexibility. Aluminum alloy is 30% more flexible than copper and 40% less resilient than copper. General copper bending radius of 10 to 20 times the diameter, while the bending radius of aluminum alloy cable is only 7 times the diameter, easier to connect the terminal.
