ACSR | Aluminum Conductor Steel Reinforced for Overhead Lines

At a Glance: ACSR | Aluminum Conductor Steel Reinforced

• Primary Use: Long distance electrical power transmission and supporting overhead electrical cables.
• Key Benefit: Combines the high strength of galvanized steel with the high conductivity of aluminum.
• Built For: Overhead traction systems and general power distribution where both high current capacity and high ultimate tensile strength ($\text{U.T.S.}$) are required.

Your Solution for High-Strength, High-Capacity Overhead Lines

The ACSR (Aluminum Conductor Steel Reinforced) conductor, also known as aluminum stranded conductor with steel reinforced, is a composite conductor specifically engineered for overhead electrical lines. These conductors are constructed from concentric-lay-stranded aluminum wires wrapped around a core of galvanized steel. This design leverages the strengths of both materials: the outer layer of aluminum ensures high current carrying capacity, while the inner steel core provides superior mechanical strength and support.

Key Features & Benefits

• Composite Construction: Made up of concentric-lay-stranded aluminum wires over a core of galvanized steel.
• Steel Core Options: The galvanized steel core typically consists of $\text{1}$, $\text{7}$, or $\text{19}$ wires, providing essential mechanical reinforcement.
• Optimized Performance: The relative proportions of aluminum and steel can be varied to achieve specific required characteristics:
  • Increased $\text{U.T.S.}$: Obtained by increasing the steel content.
  • Increased Current Carrying Capacity: Achieved by increasing the aluminum content.
• Versatility: The diameters of the steel and aluminum wires can be the same or different, allowing for highly specific conductor designs.
• Core Applications: Specially suitable for application in long distance electrical power transmission and for supporting overhead electrical cables, including use in overhead traction systems.
