Why Aluminium wires are used for High tension(HT) lines?
11 KVA/32KVA & aboue

Answer Posted / vilas

weight and cost & conductance are three factors are more
important for transmission lines, So aluminium is selected
to transmit power, as it is light weighted , cost also less
than copper, as weight is less the construction cost of
tower is less.

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
