Transcription

1 Electric Utility TransPowr AAC Bare Overhead Conductor All-Aluminum 1350 Conductor Concentric-Lay-Stranded Overhead Conductors Product Construction: Complete Conductor: Bare all-aluminum 1350 conductors (AAC) are concentric-lay-stranded conductors, consisting of one or more layers of wire wrapped helically around a straight round central wire. Each successive layer has six wires more than the layer immediately beneath. Greater flexibility is provided by increasing the number of strands for a specific cross-sectional area. AAC conductors are manufactured in accordance with the requirements of the latest issue of ASTM B231. The more commonly used strandings are 7, 19, 37, 61 and 91. The sizes and strandings listed on the following pages are commmon examples in overhead lines. Other sizes are also available. Complete Conductor (cont d.): Class AA strandings are used for bare overhead lines. The direction of lay for the outer layer is right-hand and is normally reversed in successive layers. The temper is full hard drawn (H19). Class A strandings are used primarily for overhead conductors which are to be covered with weatherresistant mater ials. Greater flexibility than Class AA is provided. The outer layer is right-hand, and the temper generally H19. Successive layers are normally reverse lay. Features and Benefits: Optimum economy is provided since the lighter weight means lower unit length costs, easier handling in installation and less-complex fittings. All-aluminum conductors have an inherent high corrosion resistance due to their homogeneous construction. Applications: Stranded bare all-aluminum 1350 conductors (AAC) are used in overhead line installations where design parameters do not require the higher strength or temperature ratings provided by ACSR, ACSS or other type conductors. Options: Compact aluminum strands (ASTM B400) Trapezoidal-shaped aluminum strands (/TW) High-conductivity aluminum (/HC) (62.2% IACS) Non-specular surface finish (/NS) For more information, or information on other conductor sizes, designs and/or specific installation requirements not shown in the tables, contact your General Cable sales representative or . 90

7 Electric Utility TransPowr AAC/TW Bare Overhead Conductor Trapezoidal All-Aluminum 1350 Concentric-Lay-Stranded Overhead Conductors Product Construction: Complete Conductor: TransPowr AAC/TW is a trapezoidal 1350 H19 aluminum (AAC) 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 AAC/TW conductors are manufactured in accordance with the requirements of the latest issue of ASTM B778. The conductor consists of two, three, four or five layers of aluminum 1350-H19 wires. The sizes and constructions listed on this and the following pages are examples used in overhead lines. Features and Benefits: TransPowr AAC/TW has a continuous operating temperature rating of 75 C. Operation of the conductor at elevated temperatures may increase the conductor sag properties and lower the rated tensile strength of the conductor. AAC/TW 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 AAC conductor. The reduced conductor diameter is advantageous in reducing the effects of ice and wind loading on the conductor. AAC/TW 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 1350 H19 aluminum conductors (AAC/TW) are used for overhead transmission lines where design parameters do not require the higher strength or temperature ratings provided by ACSR, ACSS or other type conductors. Electrical Parameters: The electrical parameters for the trapezoidal AAC equivalent circular mil area and equivalent overall diameter conductors may be found in the last table of this section. Options: High-conductivity aluminum (/HC) (62.2% IACS) Non-specular surface finish (/NS) For more information, or information on other conductor sizes, designs and/or specific installation requirements not shown in the tables, contact your General Cable sales representative or . 96
