ACSR / TW – Aluminum Conductor. Steel Reinforced / Trapezoidal Shaped Aluminum Strands. Bare

Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductor, Steel-Reinforced (ACSR/TW) – High-Performance Overhead Conductor

Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductor, Steel-Reinforced (ACSR/TW) is an advanced bare overhead conductor designed for enhanced efficiency. ACSR/TW is available in two designs:


  • Equal Area Design – Maintains the same aluminum area as standard ACSR while offering a smaller diameter, ensuring equal ampacity in a more compact size.
  • Equal Diameter Design – Matches the outside diameter of standard ACSR but allows increased ampacity for superior performance.
  •  

    With these designs, ACSR/TW enables optimized transmission capacity, reducing conductor size or increasing ampacity as needed.

    JSK ACSR/TW conductor meets or exceeds ASTM B-779 standards for Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Steel-Reinforced (ACSR/TW), ensuring durability, reliability, and efficiency in overhead power applications.

    This ACSR/TW conductor consists of 1350-H19 aluminum alloy trapezoidal-shaped wires concentrically stranded around a steel core. For added protection against corrosion, an optional grease application is available, either for the steel core or the entire cable.

    Upgrade your power transmission with a Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductor, Steel-Reinforced (ACSR/TW) for high performance, durability, and efficiency in overhead applications.

    Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductor, Steel-Reinforced(ACSR/TW) is designed for use as a bare overhead conductor. There are two designs of ACSR/TW. One design gives an equal area of aluminum when compared to the standard ACSR conductor sizes. The other design gives an overall outside diameter equal to standard ACSR conductor sizes. Use of this conductor in the equal area design allows equal Ampacity in a smaller diameter conductor when compared with standard ACSR conductor. Use of this conductor in the equal diameter design allows more ampacity in an equal diameter conductor when compared with standard ACSR conductor.

    JSK ACSR/TW conductor meets or exceeds ASTM specification: B-779 Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Steel-Reinforced (ACSR/TW).

    Aluminum alloy 1350-H19 trapezoidal shaped wires, concentrically stranded about a steel core. Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
