| Advantages
of AAAC Conductors |
| 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. |
| THERMAL STABILITY |
AAAC are stable upto 90oC
against ACSR conductors which are stable 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 supports
and other accessories in transmission line system. |
