AACSR

Aluminum Alloy Conductor, Steel Reinforced

Download PDF

Construction:

Core:Stranded standard strength steel core with Class A hot dipped zinc galvanization coating (also available in zinc-5% aluminum-mischmetal alloy coating)
Stranding:Heat-treated aluminum-alloy (6201-T81) round wire shaped strands with 52.5% conductivity

Applications and Features:

AACSR (Aluminum Alloy Conductor, Steel Reinforced) is a concentrically stranded conductor consisting of one or more layers of heat-treated 6201-T81 aluminum-alloy wires surrounding a coated steel core. The aluminum-alloy strands contribute greater strength than 1350-H19 aluminum, while the steel core provides additional mechanical reinforcement.

AACSR is used for overhead transmission and distribution applications where high tensile strength, a favorable strength-to-weight ratio, and controlled sag are important. It is well suited for long spans, heavy mechanical loading, and line designs that require greater strength than conventional aluminum conductors, with moderate electrical conductivity.

Continuous operating temperature - 75°C
Emergency operating temperature - 100°C
