Best option for overhead cable

[Alwayslearningelec]

I have a lot of large cable( 200 & 400A) that needs to be run over head free air from poles. Is an aluminum conduxtor cable the best option as far as labor and $$?

Thanks.

There are too many variables to give a reasonable answer. Consider, however, that electric utilities almost universally use aluminum (AAC), an alloy of aluminum (AAAC), or aluminum with steel core (ACRS) for overhead lines.
