ACSR - Aluminum Conductors Steel Reinforced

ACSR is made of twisted aluminum wire and steel wire, suitable for overhead transmission lines. The inside of it is a steel core, and the outside is twisted with aluminum wires around the steel core; the steel core mainly plays the role of increasing the strength, and the aluminum stranded wire mainly plays the role of transmitting electric energy.

Construction

  1. Aluminum 1350-H19 wires, concentrically stranded about a steel core. Standard core wire for ACSR is class A galvanized
  2. Class A core stranding is also available in zinc-5% aluminum-mischmetal alloy coating.
  3. For aluminum-clad (AW) ACSR, please refer to the ACSR/AW catalog sheet
  4. Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease
  5. ACSR conductor is also available in non-specular.
