All Aluminum Alloy Conductor (AAAC) Cables
Application
AAAC is mainly used as bare overhead transmission cable and as primary and secondary
distribution cable. It is also suitable for laying across basins, rivers and valleys where
special geographical teatures exist.
standard
BS EN 50182
Construction
AAAC cable bvconsists of aluminum alloy wires. The aluminum alloy wires are concentrically stranded.
This section deals with heat-treatable magnesium silicon type aluminium alloys to the
applicable International Standard, the electrical and mechanical properties of which all
fall within the values suggested by relevant standard. Conductors to all other recognized
specifications can also be supplied. The alloys referred to have higher strength but lower
conductivity than pure aluminium. Being lighter, alloy conductors can sometimes be used
to advantage in place of the more conventional ACSR; Having lower breaking loads than
the later, their use becomes particularly favourable when ice and wind loadings are low.
