Cable is the general name given to wires with a metallic conductive structure, covered with an insulating material, which enables the transmission of electrical energy produced, especially for electronic goods and intercity distribution, depending on the current. These conductors may consist of a single strand of copper, occasionally aluminum, or thin strands knitted together. In order to carry the same electric current, cables made of aluminum wire must be at least half a diameter thicker than copper wire cables.
Since copper wires can carry higher electric current with thinner structure, they are widely used in narrower areas with space constraints. Cables made of aluminum wires, on the other hand, are mostly used in overhead lines due to being a lighter metal. Such cables can be wrapped with steel wire braids to make them much stronger.
