All Aluminum Alloy Conductor (AAAC) Cables
Application of AAAC conductor 95mm2
AAAC is mainly used as bare overhead transmission cable and as primary and secondarydistribution cable. It is also suitable for laying across basins, rivers and valleys wherespecial geographical teatures exist.
standard of AAAC conductor 95mm2
Basic design to BS 3242 / BS EN 50182 / IEC 61089 / ASTM B 399/B 399M / DIN 48201-6 standards
Construction of AAAC conductor 95mm2
AAAC cable bvconsists of aluminum alloy wires. The aluminum alloy wires are concentricallystranded.This section deals with heat-treatable magnesium silicon type aluminium alloys to theapplicable International Standard, the electrical and mechanical properties of which allfall within the values suggested by relevant standard. Conductors to all other recognizedspecifications can also be supplied. The alloys referred to have higher strength but lowerconductivity than pure aluminium. Being lighter, alloy conductors can sometimes be usedto advantage in place of the more conventional ACSR; Having lower breaking loads thanthe later, their use becomes particularly favourable when ice and wind loadings are low.
