Correct option is D
The function of steel wire in an aluminum conductor steel-reinforced cable (ACSR) conductor is to provide additional mechanical strength.
Here's some more information about ACSR conductors:
· Composition: ACSR conductors are made up of high-purity aluminum outer strands and a galvanized steel center strand.
· Benefits: The combination of steel and aluminum provides a flexible and reliable conductor for power transmission and distribution applications. Steel provides the mechanical strength, while aluminum provides good conductivity and current capacity.
· Use: ACSR conductors are typically used in overhead power lines.
