HDA Conductor 50mm2 and 100mm2 :
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.

2). Construction:
HDA(AAC)cable is composed by bare concentric-lay-stranded aluminum wires with a straight round central aluminum wire surrounded by one or more layers of helically layed aluminum wires.
3). Application:
* HDA(AAC) cable is used in overhead electric power transmission and distribution lines with various grade voltages.
* Under the same weight, AAC is with higher DC resistance and lower cost than Copper conductor.
* Aluminium is light and be easy to lay.
4.Packing: Strong Wooden Drum or Iron Wooden Drum.
