Multiple Choice

Which out of the three primary types of aluminum conductors contains a steel core?

Steel reinforcement in overhead aluminum conductors is added to boost mechanical strength, allowing longer spans and heavier loads without excessive sag. In this design, a central steel core sits inside the conductor and is surrounded by aluminum strands. The steel core takes most of the tensile load and wind/temperature stresses, while the aluminum outer strands carry the electrical current. All Aluminum Conductor has no steel core—it’s made entirely of aluminum strands, so it’s lighter but not as strong mechanically. All Aluminum Alloy Conductor uses an aluminum alloy to improve strength without a steel core, giving better strength than pure aluminum but still not the same level of reinforcement as steel. Because of the steel core, the conductor that contains a steel core is Aluminum Conductor Steel Reinforced.
