Second, the cost difference The price ratio of copper and aluminum is about 3.5, so the cost of the copper conductor is seven times that of the aluminum conductor.
Third, the difference in conductivity Because the cable products are products with standard conductor specifications, it is impossible to buy aluminum core cables with the same conductivity and copper core cables. Therefore, if a cable is made of an aluminum conductor, it is necessary to use an aluminum conductor having a larger cross section. Experience has shown that in the case of equal current carrying capacity, the conductor cross section of the aluminum core cable should be twice the cross section of the copper core cable conductor. That is to say, the price advantage of aluminum and copper is not significant, because the conductor is only a small part of the overall cable cost.
