• Copper-Clad Aluminum Wire (CCA) is a conductive wire consisting of an aluminum core covered with a thin layer of copper, also known as CCA wire. It combines the lightness and cheapness of aluminum with the good conductive properties of copper. Ni aaye ohun, a lo nigbagbogbo ni awọn kemui ti o wa ninu awọn kemui ati awọn kedari agbọrọsọ ati pe o dara julọ fun gbigbe ijinna ati pe o dara fun gbigbe ijinna.
