Electrical Conductors: What They Are, Types, and Applications

Electrical cables are essential in both commercial and residential installations within the construction industry. Choosing the right type is crucial, as electrical resistance and flexibility vary according to the nominal cross-section expressed in millimeters. The larger the nominal cross-section, the greater the resistance to electrical current. Types include solid wires made from solid copper forming a conductor, cables with twisted copper wires for greater flexibility, and flexible cables with thinner wires for installations with bends.
