AAC conductors are also called aluminium stranded conductors.This British Standard applies to stranded all aluminium conductor AAC for overhead power transmission.
Aerial conductors on transmission&distribution lines are often specified where there is significant distance to cover and where these cables are best positioned far out of reaching. The distances to be covered, the environmental conditions it will be up against, and the location are made of all factors in specifying the compatible cables.
Bare AAC Cable is most commonly used in urban areas with frequent supports and short spans. They are also used in coastal regions where salt in the air can cause corrosion but the aluminium wires have its good performance of corrosion resistance.They are specified for use in the railway industry for OHL electrification.
