acsr means all alluminum steel reinforced , it means it has a steel conductor inside for reinforcing just as animals has backbone , so names of the animals & birds names with backbone are used for ASCR. AAC, All alluminum cable , the names of insects used
ACSR stands for aluminum conductor, steel reinforced. This type of conductor is used for transmission lines that are strung between poles or towers. The aluminum is used for its lower resistance, and the steel provides the structural strength.

The Bersimis ACSR Conductor have the Current Carrying Capacity 1359.6A. It is rated at stranding (Alluminium/Steel) 42/7 and Resistance DC 20 degree Celcius per 1000ft. 0.013Ω.
the main purpose of steel in acsr conductors is for mechanical strength
There are lots of choices for type of conductor - ACSR is a very common one. In my experience aluminum is the most often used metal. ACSR uses aluminum to carry the current, and also has a steel core that provides added strength.
