    Aluminum line advantages and disadvantages

    30-05-2018

    Aluminum line advantages and disadvantages: (1) Cheaper prices: Copper rods are 3.5 times the price of aluminum rods, and copper is 3.3 times that of aluminum. Therefore, aluminum wire cables are much cheaper than copper wire cables and are suitable for low-capital projects or temporary power consumption. (2) The cable is very light: The weight of the aluminum cable is 40% of the copper cable, and...
