A metallic electric powered conductor comprise of a number wires. Conductors are designed for the transmission of energy source. They are also applied to the production of conducting windings for electrical machines, transformers, electromagnets, and induction coils as well as in the wiring of electrical machines and also radio apparatus. The structural characteristics of conductors involve the amount of current-carrying strands, the materials of the strands, the shape of the cross section, the number of wires in each strand, the variety of insulation, the operating voltage, and the thermal stability.
