What is ACSR conductors
Solution
ACSR (Aluminum Conductor Steel Reinforced) conductors are widely used for electrical power transmission over long distances, since they are ideal for long overhead lines spans. They are made up of a concentrically stranded conductor of one or more layers of hard-drawn 1350-H19 aluminum wires on galvanized steel wire core. The core can be single wire or stranded, depending on the size.
The purpose of the steel core wires is to increase the strength of the conductor and therefore, improve its mechanical properties. The aluminum wires surrounding the steel core are responsible for carrying the electrical current.
The proportion of steel and aluminum in an ACSR conductor can be selected based on the mechanical strength and current carrying capacity required for the application. ACSR conductors are recognized for their record of economy, dependability, and favorable strength/weight ratio. They also have the advantage of a high tensile strength, so they can be used over long distances with fewer supports.
