What are the Advantages of Copper Core Cable Compared with Aluminum Core Cable?


1. Low resistivity: The electrical resistivity of the aluminum core cable is about 1.68 times higher than that of the copper core cable.

2. Good ductility: The elongation of copper alloy is 20~40%, the elongation of copper for electricians is above 30%, and the aluminum alloy is only 18%.

3. High strength: allowable stress at room temperature, copper is 728% higher than aluminum. Especially the stress at high temperature, the difference between the two is very far.

4.Anti-fatigue: aluminum is easy to break after repeated bending, copper is not easy. In terms of elastic index, copper is also about 1.7 ~ 1.8 times higher than aluminum.

5.Good stability, corrosion resistance: copper core oxidation resistance, corrosion resistance, while aluminum core is vulnerable to oxidation and corrosion.

6.Large current carrying capacity: Due to the low resistivity, the copper core cable of the same cross section is about 30% higher than the allowable current carrying capacity of the aluminum core cable (the maximum current that can be passed).

7.Low voltage loss: due to the low resistivity of the copper core cable, the same current flows through the same section. The copper core cable has a small voltage drop. The same transmission distance guarantees high voltage quality. Under the allowable voltage drop condition, the copper core cable transmission power reaches a long distance, that is, the power supply coverage area is large, which is beneficial to the network planning and reduces the number of power supply points.

8. Low heating temperature: Under the same current, the copper conductor of the same section has a much lower heat generation than the aluminum core cable, making the operation safer.

9. Low energy consumption: Due to the low resistivity of copper, it is obvious that the power loss of copper cables is lower than that of aluminum cables. This is conducive to improving power generation efficiency and protecting the environment.

10. Anti-oxidation, corrosion resistance: copper-core cable connector performance stability, not due to oxidation accident. The joint instability of aluminum core cable often causes the contact resistance to increase and heat up due to oxidation. As a result, the accident rate is much larger than the copper core cable.

11. Convenient construction:

The copper core is flexible, the allowable bend radius is small, so the bend is convenient and the pipe is easy to pass through; Copper core anti-fatigue, repeated bending is not easy to break, so the wiring is convenient; The copper core has high mechanical strength and can withstand large mechanical tension, which brings great convenience to construction laying and creates conditions for mechanized construction.
