Conductor is one main of parts for electrical systems or transmission and distribution power lines. There are many Conductor materials used for transporting the power.

Conductor materials normally has
◆ Copper: which is one ideal material overhead lines owning to its high electrical conductivity and greater tensile strength
◆ Aluminum: which is cheaper price and lighter weight than copper conductor
◆ Steel-cored aluminum: ASCR conductor is one popular conductors used for overhead lines, also called aluminum conductor steel reinforced
◆ Galvanized steel: which has highest tensile strength, used for long spans overhead lines
◆ Cadmium copper: also called copper alloy

The properties of Conductor materials
◆ High electrical conductivity
◆ High tensile strength
◆ Withstand mechanical stress
◆ Low costs
◆ Hot competitive

The most commonly material for overhead lines or family lines are copper, aluminum, galvanized steel, and others. Sometimes, the water is used as conductor.
