1. Low resistivity: The resistivity of aluminum core cable is about 1.68 times that of copper core cable. Guangxi Cable

2. Good ductility: the ductility of copper alloy is 20~40%, the ductility of electrical copper is more than 30%, the ductility of aluminum alloy is only 18%.Guangxi cable

3. High strength: the allowable stress at room temperature, copper is 7~28% higher than that of aluminum. Especially the stress at high temperature, the difference between the two is even greater.

4. Anti-fatigue: aluminum is easy to break after repeated bending, while copper is . In terms of elasticity index, copper is also about 1.7~1.8 times higher than aluminum.

5. Good stability corrosion resistance: the copper core is resistant to oxidation corrosion, the aluminum core is easy to oxidize resist corrosion.Guangxi wire cable

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

7. Low voltage loss: Due to the low resistivity of copper core cables, the same current flows through the same section. The voltage drop of copper core cable is small. The same power transmission distance can ensure higher voltage quality; in the case of allowable voltage drop, the copper core cable can transmit power to a longer distance, that is, the power supply coverage is large, which is conducive to network planning reduces the number of power supply points.

8. Low heating temperature: Under the same current, the heating value of the copper core cable with the same cross-section is much smaller than that of the aluminum core cable, the operation is safer.

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

10. Anti-oxidation corrosion resistance: The joint performance of the copper core cable is stable, there will be no accidents due to oxidation. The joints of aluminum core cables are often unstable due to oxidation, which increases contact resistance generates heat, causing accidents. Therefore, the accident rate is much higher than that of copper core cables.

11. Convenient construction:

The copper core is flexible, allowing a small radius of curvature, which is convenient for bending passing through pipes;Guangxi cable manufacturer

The copper core is fatigue-resistant, easy to be broken after repeated bending, easy to connect; Guangxi wire cable

Due to the high mechanical strength of the copper core, it can withstand large mechanical tension, which brings great convenience to the construction laying, also creates conditions for mechanized construction.
