Description: Similar to All Aluminum Conductor, this conductor is centered by a steel galvanized central core.  The steel core can be varied to achieve the desired durability and conductor strength.  The outer layers of this conductor are made of aluminum, providing a corrosion-resistant, long-lasting product.  Application of grease to the core or to the entire cable can further improve the cable’s resistance to corrosion.

Applications: Like AAC, ACSR is primarily used as an overhead transmission cable and can also be used for primary and secondary distribution.  This conductor is typically preferred in a heavy construction area because of its reinforced steel core.  Although it is heavier than AAC, it can be moved in and out of a construction area relatively easily.  This cable is also useful in areas with high winds or frequent storms.

Specifications:
In accordance with specifications set forth by the American Society for Testing and Materials:
• This product is composed of a variety of aluminum conductors.  B-230, 231, and 232.
• Steel reinforced core is coated with B-341 aluminum, B-498 Zinc, and B-802 Zinc-5% Misch Metal alloy.

Construction:
• Conductor - ACSR is constructed with aluminum alloy 1350-H19
• Stranding - Wires are concentrically stranded.
• Reinforcement - A core consisting of class A, B, or C galvanized steel lays in the center of the cable.  Aluminum coating (AZ) or aluminum-clad (AW) options are available to enhance the core’s longevity.
