Advantages and disadvantages of copper cables compared to AAC conductors

In everyday life, we often used copper core and AAC Conductor, then they each have what kind of features, and we choose these cables in what situation? Here we will explain to you carefully copper cable and AAC Conductor advantages and disadvantages of each are different.

1. Resistivity: resistivity of AAC Conductor higher than copper cable approximately 1.68 times.

2. Extensibility: copper alloy extension rate of 20% to 40%, electrician elongation of 30% or more of copper, while aluminum is only 18%.

3. The strength: at room temperature, copper is 7% to 28% higher than aluminum, if it is at a high temperature, a difference of more.

4. Anti-fatigue: Aluminum repeatedly bending easily broken, copper is easy. Flexible indicators, copper is about 1.7 to 1.8 times higher than aluminum.

5. Corrosion: copper core anti-oxidation, corrosion resistance, strong stability. The aluminum is susceptible to oxidation and corrosion.

6. Carrying capacity: In the case of low resistivity, the cross-section of copper cable AAC Conductor allows the carrying capacity (maximum current that can pass through) to be about 30% higher.

7. Low voltage loss: As low resistivity copper cable in the same cross-section through the same current flows in the case. The copper cable voltage drop is small. Thus, the same transmission distance, to ensure a higher voltage quality; or, in the allowable voltage drop conditions, copper cable transmission can reach longer distances, which supply a large coverage area is conducive to the planning of the network, reducing set the number of supply points.

8. The heating temperature is low: in the same current, the same cross-section of copper cable the cable is much less heat than aluminum, making the operation safer.

9. Low energy consumption: To the low resistivity of copper, compared to AAC Conductor, the power loss of the low copper cable, is obvious. This helps to improve power generation efficiency and protect the environment.

10. The anti-oxidation, anti-corrosion: copper cable connector performance stability, not an accident due to oxidation. AAC Conductor connector is often unstable due to oxidation of the contact resistance increases, heating, and accidents. Therefore, the accident rate is much greater than with copper cable.

11. Construction of convenience: ① copper core flexibility, small bend radius allowed, so turning easy, easy to wear tube; ② copper core anti-fatigue, repeatedly bent not broken, so easy to wire; ③ copper core high mechanical strength, energy withstand greater mechanical tension, to the construction laying great convenience, but also to create the conditions for the mechanization of construction.

Of course, AAC Conductor also has its own advantages, 1, cheap: The price of copper is 3.5 times that of aluminum, which is 3.3 times the proportion of aluminum, aluminum cable in the price so high advantages for a low-funded project or temporary electricity. 2, the cable light: because the weight of aluminum is 40% of the copper cable, the transportation cost of construction will be greatly reduced.
