Explain the suitability of aluminium that is used as electrical conducting materials.
Aluminium: Conductors are appropriate for ambient and very high temperature. Use of aluminium as an electrical material mainly in aircraft industries has a considerable advantages due to the saving in weight. Due to its lightness is being used for bus bars. The current carrying capacity of it is 75 percent of copper and its density being around one third that of copper and aluminium bus bar is only around half the weight of copper bus bar of equivalent current carrying capacity. There steel reinforced aluminium conductor is extensively being used for long span transmission lines.
