Conductive properties
The conductivity of the aluminum alloy cable is 61.5% of the copper IACS, the most commonly used reference material, and the current carrying capacity is 79% of the copper cable, which is superior to the pure aluminum standard.
Creep resistance
The alloy material and annealing process of aluminum alloy cable reduces the tendency of the conductor to "creep" under heat and pressure. Compared with pure aluminum, the creep resistance is improved by 300%, avoiding the problem of slack caused by cold flow or creep. .
Tensile strength and elongation
Compared with pure aluminum conductors, aluminum alloy cables have increased the tensile strength and increased the elongation to 30% due to the addition of special components and special processing techniques. The use is safer and more reliable.
Thermal expansion coefficient
The coefficient of thermal expansion is used to calculate the dimensional change of the material as the temperature changes. Aluminum alloys have a thermal expansion coefficient comparable to that of copper. Aluminum connectors have been used reliably for copper and aluminum conductors for many years, and most of the electrical connectors used today are made of aluminum, which is especially suitable for aluminum alloys. Therefore, the aluminum alloy conductor is completely identical to the expansion and contraction of the connector.
Strong self-weight bearing capacity
The aluminum alloy improves the tensile strength of pure aluminum. The aluminum alloy cable can support the self-weight of 4000 meters in length, and the copper cable can only support 2750 meters. This advantage is particularly evident when wiring large-span buildings such as stadiums.
Corrosion resistance
The inherent corrosion resistance of aluminum results 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 rare earth element added in the alloy can further improve the corrosion resistance of the aluminum alloy, especially electrochemical corrosion. The ability of aluminum to withstand harsh environments has made it widely used as a conductor for cables in pallets, as well as many industrial components and containers. Corrosion is usually associated with the connection of different metals in a humid environment, and appropriate protective measures can be used to prevent corrosion, such as the use of lubricating oils, antioxidants and protective coatings. Alkaline soils and certain types of acidic soil environments are highly corrosive to aluminum, so direct-buried aluminum conductors should be insulated or molded to prevent corrosion. In sulfur-containing environments, such as railway tunnels and the like, aluminum alloys have much better corrosion resistance than copper.
Flexibility
The aluminum alloy cable has good bending performance, and its unique alloy formula and processing technology greatly improve the flexibility. Aluminum alloy is 30% more flexible than copper, and its rebound is 40% lower than copper. Generally, the bending radius of the copper cable is 10 to 20 times the outer diameter, and the bending radius of the aluminum alloy cable is only 7 times the outer diameter, which makes it easier to connect the terminals.
