TransPowr® Self-Damping Aluminum Conductor Steel Reinforced ACSR/SD

General Cable's TransPowr® Self-Damping Aluminum Conductor Steel Reinforced (ACSR/SD) cable permits longer spans, provides increased reliability, and lowers overall line cost. It also reduces sag, as well as cuts ice and wind loads. The steel core and the two layers of trapezoidal shaped aluminum wires in this design are separated by a gap designed to provide self-damping characteristics to control aeolian vibration—eliminating the need for vibration dampers


    • Concentrically stranded conductor consisting of two layers of trapezoidal shaped aluminum alloy 1350-H19 wires around a stranded steel core*
    • Meets or exceeds industry requirements per ASTM specification B701
    • Steel core corrosion protection from galvanized, aluminized (AZ), or zinc-5% aluminum mischmetal alloy (Zn-5Al-MM) coatings with aluminum cladding (AW) also available
    • Steel core is available in Standard, High, Extra High, and Ultra High strengths
    • Available with an optional low reflectivity ‘non-specular’ finish

*Note: On certain larger conductor constructions, the trapezoidal shaped wires are surrounded by a layer of round 1350 H-19 aluminum wires.
