AAC with IEC61089 Standard

Application

The conductors are suitable for use in spans on wood poles, transmission towers,and other structures where tensile strength and temperature ratings are not required. Application 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 handing during installation and use of simpler fittings. The conductor is corrosion resistant due to its homogeneous construction.

Construction

Aluminum 1350 wires are concentrically stranded and 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.
