1.ALL ALUMINUM ALLOY CONDUCTOR -AAAC

AAAC (All Aluminum Alloy Conductor)have been widely used in power transmission lines with various voltage levels, and also used in power lines across great rivers, heavy ice area, and other places special geographical characteristics. The conductor have excellent advantages of high strength, large current carrying capacity and good catenary property as well as wear-resistance, anti-crush and corrosion-proof with simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity.referred to have higher strength but lower conductivity than pure aluminum.being lighter, alloy conductors can sometimes be used to advantage in place of the more conventional ACSR;having lower breaking loads than the latter,their use becomes particularly favourable when ice and win loadings are low.

2.Standard
We can supply this conductor according to different recognized standards,such as BS EN50182,IEC61089,ASTM B399,DIN 48 201, customer special specification also can be satisfied.

3.Advantage :
Corrosion Resistance:AAAC exhibits excellent corrosion resistance specially in sea coast areas and in polluted industrial areas due to absence of steel core.
Lower Power losses:Since AAAC is homogeneous (with all strands of Aluminium Alloy) with no steel component the resistance of AAAC is lower as compared to ACSR.
Higher Ampacity:AAAC can carry atleast 15-20% extra current as compared to ACSR of equal size
Longer Life:Experience in foreign countries shows that All Aluminium Alloy Conductors are in service for over 60 years, which is about double the life of ACSR Conductors.
Surface Hardness:The surface hardness of AAAC is 80 BHN as compared to 35 BHN of ACSR. This reduces the damage to surface during handling and therefore leading to lesser corona losses and ratio interference at EHV.
Therma Stability:AAAC are stable upto 90oC against ACSR conductors which are st-able upto 75oC.
Higher Strength To Weight Ratio:Since AAAC has higher strength to weight ratio,span can be increased from 2 to 15% resulting in overall reduction of cost in towers sup-ports and other accessories in transmission line system.
