All aluminum 1350 conductor concentric lay -stranded
Complete Conductor:
Bare all-aluminum 1350 conductors (AAC) are concentric-lay-stranded, 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 applicable issues of ASTM (specifications B230 and B231 & DIN). The more commonly used standings are 7, 19, 37, 61 and 91 standings are also available
Complete Conductor (cont’d):
Class AA standings 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).
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:
- Trapezoidal-shaped aluminum strands (/TW)
- High-conductivity aluminum (/HC) (61.8% IACS)
