The difference between copper conductor and aluminum conductor:
 
For wire and cable industry, the most obvious alternative is to use aluminum conductors instead of copper conductors. When the relative cost of copper and aluminum conductors is to be considered, the price, the proportion and the electric conductivity can be considered in order to get the real answer to the cost of the aluminum conductor. Copper ratio. The proportion of copper is 8.9gNaN3, the proportion of aluminum is 2.7g/cm3, that is, in the case of the same size of the conductor, the weight of the copper conductor is 3.3 times that of the aluminum conductor. However, the electrical conductivity of aluminum is only 61%, that is, in the same case, the cross section of the aluminum conductor is 61% more than that of the copper conductor. So, in terms of the weight of the conductor, it is necessary to make the two conductors of the same carrying capacity, the required weight of the copper conductor is about 2 times that of the aluminum conductor. In addition, the aluminum price ratio is about 3.5, therefore, the equivalent copper conductor cost is 7 times of aluminum conductor.
 
Because the cable products are products that have standard conductor size limit, it is impossible to buy the same aluminum conductor cable with copper conductor cable. Therefore, if an aluminum conductor is used to make the cable, a larger aluminum conductor must be used. Experience has shown that in the case of equal load flow, the conductor cross section of the aluminum conductor cable should be 2 times the conductor cross section of the copper conductor. Since the aluminum core cable conductor section is copper core cable conductor 2 times, so followed by aluminum core cable insulation, sheath and armor materials increased, weakened the price advantage of using aluminum conductor. That is to say, the price advantage of aluminum and copper is not much, because after all, only a small part of the entire cable costs.
 
From what has been discussed above, copper conductor is common used in many industry. Jiapu cable not only produce copper conductor cable, but also can design the aluminum conductor cables according to users' requirement.
