Copper :
Either bare or tinned, copper is the most commonly used conductor metal.
Selecting the Conductor size:
Even in the design of a simple single insulated busbar many factors must be considered such as temperature, voltage, DC resistance of the conductor, insulation, O.D., required flexibility, physical properties of the conductor (tensile strength, voltage drop, conductivity, weight) and when necessary, specific electrical characteristics such as the dielectric properties of the insulating material.
Conductor size:
Size Determined with regard to DC resistance, current carrying capacity and breaking strength requirements.
