The following points highlight the seven main types of conductors used in transmission and distribution of electric power. The types are: 1. Stranded Hard Drawn Copper 2. Aluminium 3. Steel-Cored Aluminium 4. Galvanised Steel 5. Cadmium Copper 6. Copper-Clad Steel 7. Phosphor Bronze. Type # 1. Stranded Hard Drawn Copper: Hard drawn copper conductor is the best conductor owing to [...]
The demand of electric power is increasing throughout the world and in many countries it is doubling every five to eight years. The power stations (hydro, thermal or nuclear) are usually located far away from the load centres. Thus transmission of large amounts of power over long distances, which can be accomplished most economically only by using extra high voltages [...]
