Advantages of aluminum alloy cables

Introduction of the advantages of aluminum alloy cable


If you are looking for more details, kindly visit Mingda.

Conductive Properties

The electrical conductivity of aluminum alloy is 61.5% of the most commonly used reference material copper IACS, and the current carrying capacity is 79% of copper, which is superior to the pure aluminum standard.


Creep Resistance

The alloy material and annealing treatment of aluminum alloy conductors reduces the "creep" tendency of the conductor under heat and pressure. 

Compared with pure aluminum, the creep resistance is improved by 300%, avoiding cold flow. Or the problem of relaxation caused by creep.


Tensile Strength and Elongation

Aluminum alloy conductors compared to pure aluminum conductors, due to the addition of special components and the use of special processing technology, greatly improved the tensile strength, and the elongation increased to 30%, It is safer and more reliable to use.


Thermal Expansion Coefficient

The thermal expansion coefficient is used to calculate the dimensional change of the material when 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 meters in length, and the copper cable can only support meters. This advantage is particularly evident when wiring large-span buildings such as stadiums.


Anti-Corrosion Properties 

The inherent corrosion resistance of aluminum comes from the formation of a thin and strong oxide layer when the aluminum surface is in contact with air. 

This oxide layer is particularly resistant to various forms of corrosion. For example, in railway tunnels and other similar places, the corrosion resistance of aluminum alloys is much better than that of copper.


Flexibility 

The aluminum alloy has good bending properties. Aluminum alloy is 30% more flexible than copper, and its rebound is 40% lower than copper.

It&#;s common to find aluminum alloy cable in today&#;s building materials market, which is the latest high-tech product of the cable. Customers many pay much attention to its merits and demerits, let&#;s discuss in detail.

 

1. Creep resistance

The special technique of aluminum conductor can reduce the deformed tendency of aluminum alloy, compared to the pure aluminum, the resistance of aluminum alloy is increased by 300%, and thus it can avoid slack caused by cold flow or deformation.

 

2. Tensile strength and elongation

Compared to the pure aluminum conductor, the aluminum alloy one has special component and processing technology, therefore, aluminum alloy conductor can greatly improve the tensile strength and elongation rate increased to 30%, securer to use.

 

3. The thermal expansion coefficient

Thermal expansion coefficient is used to calculate the size of the change in temperature of the material. The copper and aluminum alloy have equivalent coefficient. The aluminum connector used in cooper and aluminum conductors for many years. Most of today&#;s electrical connectors are made of aluminum alloy. The expansion and contraction are exactly the same with aluminum alloy conductor and connector.

 

4. Connectivity

The electrical connectors made of aluminum alloy or copper are secure and stable. The components of aluminum alloy improved its connectivity, when the conductor annealing, added iron produced high resistance, even after overload and overheating, can also ensure the stability of the connection.

 

5. Strong weight bearing capacity

Aluminum alloy improves the tensile strength of pure aluminum; aluminum alloy cables can afford the weight of meters, but copper can only offer meters. This advantage can be particularly prominent when cables applied in large-span buildings, such as stadiums.

 

6. Anti-corrosion capacity

When aluminum expose to the air, it will form the oxide layer, it is the inherent corrosion resistance of aluminum, and the oxide layer can resist any kind of corrosion. The tombar thite added to the aluminum alloy can improve its resistance, which can particularly against the electrochemical corrosion. Aluminum can withstand the harsh environment so that it is widely used in the conductor of cables and many industrial fittings. Corrosion usually associated with different metal connection in a humid environment, we can take relative measurements to prevent corrosion, for example, using lubricate and antioxidants. Alkaline and acid soil will contribute to the corrosion of aluminum, so the protective casing is necessary. In sulfur-containing environments, such as railway tunnels and other similar places, the anti-corrosion capacity of aluminum alloy is superior to copper.

 

7. Flexibility

Aluminum alloy has good flexibility; its unique formula and processing technology greatly improve its flexibility. Compare to copper cables, aluminum alloy has 30% higher flexibility and 40% lower rebound. Copper cable has 10 to 20 times diameters than it bend radius, but aluminum alloy only 7 times so it is easier to connect terminals.
