Overhead Bare Aluminum Conductor Wire AAAC Code 300mm2 Nominal Area DIN48201 image
Overhead Bare Conductor Wire AAAC Code 300mm2 (Nominal Area: 299.43mm2, 61/2.5) according to DIN48201
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.
Advantage
1. Corrosion Resistance: AAAC exhibits excellent corrosion resistance specially in sea coast areas and in polluted industrial areas due to absence of steel core.
2. 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.
3. 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.

STANDARD
Basic design to BS 3242 / BS EN 50182/ NFC34125 / IEC 61089 / ASTM B 399/B 399M / DIN 48201 -6 standards.
CONSTRUCTION
AAAC conductor is a concentric lay stranded conductor consisting of Aluminum Alloy 6201-T81 wires, similar in appearance to a 1350 grade aluminum conductor.
Notes: DC resistance at 20°C of the 6201-T81 alloy has a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.
Standards: AAAC conductors meet or exceed the following DIN 48201
