Multiple Choice

Which of the following is a correct expansion of ACSR?

Aluminum Conductor Steel Reinforced. This type of conductor uses aluminum strands that surround a steel core, combining good electrical conductivity with high tensile strength. The steel core carries most of the mechanical load, allowing long spans and preventing excessive sag, while the aluminum strands carry the electrical current. The other options don’t reflect the actual term or construction: they either misstate the material roles or introduce elements (like stainless reinforcement) that aren’t used in this standard type of conductor.
