Aluminium Overhead Conductors
( AAC , AAAC , ACSR )
Layers Construction
- ACSR : St / Al
- AAC : Al
- AAAC : Al Alloy
AAC: All Aluminium Conductors | AAAC: All Aluminium Alloy Conductors | ACSR: Aluminium Conductor, Steel Reinforced
Cable Structure
Conductor material & class:
In AAC cables the strands of hard drawn aluminium conductors are twisted together with controlled lay length to form a good construction and to withstand tensile forces when installed in the line.
In AAAC cables the strands of hard drawn aluminium alloy conductors are twisted together with controlled lay length to form a good construction and to withstand tensile forces when installed in the line.
In ACSR cables the strands of hard drawn aluminium conductors are twisted around a central galvanized high carbon steel wire(s) to withstand more tensile forces.
