Why is the price of copper core cable expensive

Copper core cable is 30% more expensive than aluminum core cable. On the whole, the price of copper core cable is higher than that of aluminum core cable, which also depends on the brand, manufacturer, model and specification. Different cable manufacturers give different prices. It is recommended to select the best. Of course, the premise is to ensure the quality of the cable.
Advantages of copper core wires and cables:
1. low energy consumption: due to the low resistivity of copper, compared with aluminum cable, the power loss of copper cable is low. This is conducive to improving the utilization rate of power generation and protecting the environment.
2. good stability: copper core is resistant to oxidation and corrosion, while aluminum core is easy to be oxidized and corroded.
3. high strength: the allowable stress of copper is 7~28% higher than that of aluminum at room temperature.
4. fatigue resistance: aluminum is easy to break after repeated bending, while copper is not. In terms of elasticity index, copper is also about 1.7~1.8 times higher than aluminum.
5. low resistivity: the resistivity of aluminum core cable is about 1.68 times higher than that of copper core cable.
6. large current carrying capacity: due to low resistivity, the allowable current carrying capacity (the maximum current that can be passed) of copper core cable with the same section is about 30% higher than that of aluminum core cable.
7. good ductility: the ductility of electrical copper is more than 30%.
8. the wire and cable are easy to construct: ① the copper core is flexible and the allowable bending radius is small, so it is convenient to turn and pass through the pipe; ② The copper core is anti fatigue and not easy to break after repeated bending, so the wiring is convenient; ③ The copper core has high mechanical strength and can bear large mechanical tension, which brings great convenience to the construction and laying, and also creates conditions for mechanized construction.
