What is the difference between copper and aluminum core cables?
1, the difference in cost advantage: copper rod is 3.5 times the price of aluminum rod, copper is 3.3 times the weight of aluminum, therefore, equal to the cost of copper conductor is 7 times that of aluminum conductor, so the cost advantage of aluminum core cable copper core cable It is impossible to achieve.
2. Conductivity difference Because the cable product is a product with a standard conductor size limit, it is impossible to purchase an aluminum core cable whose conductivity is exactly equal to the copper core cable. Therefore, if you use aluminum conductors to make cables, you must use larger aluminum conductors. Experience has shown that in the case of equal current carrying capacity, the conductor cross-section of the aluminum core cable should be twice as large as that of the conductor of the copper core cable. This means that the price advantage of aluminum and copper is not significant because the conductor is only a small part of the cost of the entire cable.
3, weight difference The weight of copper is heavier than aluminum, the specific gravity of aluminum is 2.7g/cm3, and the proportion of copper has reached 8.9g.cm3. If the conductor is the same in size, the weight of copper conductor is 3.3 of aluminum conductor. Times. However, the conductivity of aluminum is only 61% of that of copper, that is, in the case of the same transmission current, the cross section of the aluminum conductor is 61% larger than that of the copper conductor. Therefore, in terms of conductor weight, to make the two conductors have the same current carrying capacity, the weight of the copper conductor required is about twice that of the aluminum conductor.
