Products details of Aluminum Conductor Steel Supported(ACSS) - ASTM B856

ACSS conductors are manufactured in accordance with the latest issue of ASTM B856. The steel strands form the central core of the cable, around which is stranded one or more layers of aluminum 1350-O wires.

The “O” temper of the aluminum, a fully annealed or soft temper, causes most or all of the mechanical load on ACSS to be carried by the steel.

Standard ACSS designs are manufactured with regular-strength Class A zinc-5% aluminum mischmetal alloy-coated steel core (/MA2). The steel core may consist multiple wires.


  1. Aluminum conductor steel-supported (ACSS) is used for overhead transmission lines.
  2. It is especially useful in reconductoring applications requiring increased current with existing tensions and clearances.
  3. New line applications where structures can be economized due to reduced sag.
  4. New line applications requiring high emergency loadings; and lines where aeolian vibration is a problem.

Product Features

  • Operates continuously at high temperatures up to 250 °Cwith appropriate steel core coating vs. 100 °C for standard ACSR.
  • Carries substantially more current than standard ACSR.
  • Less susceptible to aeolian vibration fatigue due to the very low mechanical load on the annealed aluminum wire.
  • Can be installed to the maximum tensions.
  • Minimum average conductivity of 63% ICAS exceeds average conductivity of 61.2% ICAS for EC 1350 H19 aluminum.
  • Reduced sag allows for lower transmission tower height.
  • Long term creep is not a factor.
