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
The ampacity for copper is 1000A per square inch, in some places is 700A psi.
No. The larger the conductor the lower the resistance and the higher the ampacity.
Single Circuit PantherACSR Conductor
It doesn't really matter what the distribution voltage is. Line loss is dependant on the current through the conductor. #4 ACSR (aluminum conductor, steel reinforced, used in electrical transmission), has a typical resistance of 0.399 ohms per 1000 feet, and a maximum ampacity of 140. At max load, the I^2 * R loss would be about 7.82kW per 1000 feet of cable, or about 123kW per mile of 3-phase distribution. A 14,400 volt 140A system delivers about 3.48MW at unity power factor, so this represents about a 3.5% loss per mile, which is why 14.4kV is used for distribution, not transmission. Most likely, the cable would reach thermal limit well before 140A, and so would never be loaded to the max ampacity, so this is the theoretical max. At a more reasonable current, line loss would be correspondingly less.

The ampacity rating for 18AWG wire is typically around 16 amps.
The ampacity of 18 gauge wire is typically around 16 amperes.
ACSR (Aluminum Conductor Steel Reinforced) has the advantage of combining the lightweight properties of aluminum with the strength and durability of steel. This makes it suitable for overhead power lines where high tensile strength and conductivity are required. ACSR conductors can efficiently transmit electricity over long distances and in various weather conditions.
An ampacity is the root mean square of the electrical current which a device can carry within a specific environment, measured in amperes.
