All Aluminum Conductor (AAC) Cables
Application
AAC conductor is also known as aluminium stranded conductor. It is manufactured from electrolytically refined aluminium, with a minimum purity of 99.7%.
Standard
Basic design to BS 215-1 / BS EN 50182 / IEC 61089 / ASTM B 231/B 231M / DIN 48201-5 standards
Construction
![]() |
Concentric lay stranded Aluminium Conductor ( AAC) is made up of one or more strands of hard drawn 1350 aluminum alloy. These conductors are used in low, medium and high voltage overhead lines.
AAC has seen extensive use in urban areas where spans are usually short but high conductivity us required. The excellent corrosion resistance of aluminium has made AAC a conductor of choice in coastal areas.
Because of its relatively poor strength to weight ratio, AAC had limited use in transmission lines and rural distribution because of long spans utilized.
All aluminium conductors are made up of one or more strands of aluminium wire dep.
