Copper core cables aluminum core cables have their own advantages disadvantages. Today, Guangxi cable manufacturers will take a look at the various characteristics of these two cables.

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

2. Good ductility: the elongation of copper alloy is 20-40%, that of electrical copper is more than 30%, that of aluminum alloy is only 18%.

3. High strength: The allowable stress at room temperature is 7~28% higher than that of aluminum. Especially the stress at high temperature, the two are far each other.

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

5. Good stability corrosion resistance: the copper core is resistant to oxygen easy to corrode, the aluminum core is easy to be oxidized corroded.

6. Large current: Due to the low resistivity, the allowable current of copper core cables with the same cross section is about 30% higher than that of aluminum core cables.Guangxi wire cable

7. Low voltage loss: due to the low resistivity of the copper core cable, when the same current flows through the same section. Copper core cable voltage drops. The same transmission distance can ensure higher voltage quality; under the condition of allowable voltage drop, the transmission of copper core cable can reach a longer distance, that is, the power coverage area is large, which is conducive to network planning reduces the number of power points.

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

9. Guangxi cables have low energy consumption: due to the low resistivity of copper wires, copper wires have more power loss than aluminum wires. This is conducive to improving the utilization rate of power generation protecting the environment.

10 The copper core cable connector has stable performance will cause accidents due to oxidation. When the aluminum core cable connector is unstable, the contact resistance will increase due to oxidation, an accident may occur when heat is generated. Therefore, the accident rate is much higher than that of copper core cables.

11. Convenient construction:

The copper core is soft, the bending radius is small, the bending is convenient, the intubation is easyGuangxi cable manufacturer

The copper core is anti-fatigue, easy to be broken after repeated bending, convenient for wiring;

The copper core has high mechanical strength can withstand large mechanical tension, which brings great convenience to construction laying, also creates conditions for mechanized construction.
