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.
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
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
