1 TransPowr Bare Overhead Conductor 18/7 20/7 21/7 22/7 36/7 36/19 38/19 39/19 64/19 Product Construction: Complete Conductor: TransPowr 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. Conductor designs that maintain the same circular mil cross-sectional area of aluminum as a conventional round conductor result in a TW conductor that is 10 to 15 percent smaller in overall diameter. Conductor designs that maintain the same overall diameter as a conventional round conductor result in a TW conductor that has 20 to 25 percent more aluminum cross-sectional area packed in. The conductors are manufactured in accordance with the requirements of the latest issue of ASTM B779. The steel strands form the central core of the conductor, around which is stranded two, three or four layers of aluminum 1350-H19 wires. The steel core may consist of a concentric stranded cable of 7, 19 or more wires. Numerous combinations of aluminum and steel strands and layers are possible. The sizes and constructions listed on the following pages are common examples used in overhead lines. For conductors, the standard Class A galvanized coating is usually adequate for ordinary environments. Features and Benefits: TransPowr has a continuous operating temperature rating of 75 C. ACSR and conductors have an industry-accepted shortduration maximum operating temperature rating of 100 C. Operation of the conductor at elevated temperatures may increase the conductor sag properties and lower the rated tensile strength of the conductor. TransPowr conductors are recognized for their record of economy, dependability and favorable strength-to-weight ratio. conductors constructed of equivalent aluminum circular mil cross-sectional area provide a conductor that is smaller in overall diameter than the equivalent conventional round wire ACSR conductor. The reduced conductor diameter is advantageous in reducing the effects of ice and wind loading on the conductor. conductors constructed to be equivalent overall diameter enable a greater circular mil crosssectional area of aluminum within the conductor, reducing power loss in the conductor for day-today operations as well as allowing a significant increase in conductor current-carrying capacity. Applications: Trapezoidal aluminum conductors steel-reinforced () are used for overhead transmission lines.
