All Aluminum Conductor (AAC)

Application

The conductors are suitable for use in low, medium and high voltage overhead lines. AAC has seen extensive use in urban areas where spans are usually short but high conductivity is 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.

Property

AAC (All Aluminum Conductor) is the most economical bare overhead conductor due to its lighter weight. It offers easier handling during installation and use of simpler fittings. The conductor is corrosion resistant due to its homogeneous construction.

• high Current Carrying Capacity
• excellent resistance to corrosion
• Ideal for use in coastal area
• suitable for low & medium voltage lines in urban area

Specification

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.
