AAAC All Aluminium Alloy Conductor BS 3242 Standard
Applications
All Aluminum Alloy Conductors are mainly used as bare overhead transmission cable and as primary and secondary distribution cable. AAAC conductors are also suitable for laying across basins, rivers and valleys where special geographical features exist.
Construction
All Aluminum Alloy Conductor consists of aluminum alloy wires.
These aluminum alloy wires are concentrically stranded.
Aluminum alloy 6201-T81 wires available in both single layer and multi-layer constructions.
Feature
AAAC: All Aluminum Alloy Conductor is used for primary and secondary overhead transmission and distribution services. This has been designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio and better sag characteristic. AAAC conductors have a higher resistance to corrosion than ACSR.
