why aluminum wires are used in poles to transfer electricity for large scale.

Expert Answer:

Dear student
 
High-voltage overhead conductors are not covered by insulation. The conductor material is nearly always an aluminium alloy, made into several strands and possibly reinforced with steel strands.
 
Copper is sometimes used for overhead transmission but aluminium is lower in weight for equivalent performance, and much lower in cost.
 
That is why Al is preferred.
 
We hope that clarifies your doubt
