Product Name: TransPowr® ASCR/TW Bare Overhead Conductor & TransPowr®ACSR/SD Bare Overhead ConductorProduct Characteristic: 1350-H19 aluminum wires, concentrically strandedThe TransPowr® ASCR/TW Bare Overhead Conductor is a trapezoidal aluminum conductor steel-reinforced concentric-lay-stranded conductor. The aluminum strands are trapezoidal in shape. The wedge-shaped aluminum strands enable a more compact alignment of the aluminum wires.The TransPowr®ACSR/SD Bare Overhead Conductor are manufactured with two layers of 1350 H19 trapezoidal-shaped aluminum wires concentrically stranded around a steel core of round coated steel wires. On certain larger conductor constructions, the trapezoidal-shaped wires are surrounded by a layer of round 1350 H19 aluminum wires. The steel core and the two layers of trapezoidal- shaped aluminum wires in ACSR/SD are separated by a gap designed to provide self-damping characteristics to control Aeolian vibration—eliminating the need for vibration dampers.This EPD includes results for the following products: POTOMAC/ACSR/TW/GA2/NS
