477 MCM Cosmos AAC Bare Aluminum Conductor

Application:
This wire is suitable for use in spans on wood poles, transmission towers, and other structures where high tensile strength is not required. Applications range from extra high voltage (EHV) transmission lines to sub-service spans at distribution or utilization voltages on private premises.

AAC (all aluminum conductor) is the most economical bare overhead conductor due to its lighter weight. It offers easier handling during installation and use of simpler fittings. The wire is corrosion resistant due to its homogeneous construction.

Applicable Standards:

-ASTM B-230: Aluminum 1350-H19 wire for electrical purposes.
– ASTM B 231: Concentric Lay Stranded Aluminum 1350 Conductors.

Construction:
Aluminum alloy 1350 wires concentric lay stranded wrapped helically around a central wire. Each successive layer has six wires more than the previous underlying layer. Outer layer is right hand lay and reversed in successive layers.
