AAC/AAAC Bare Conductor

All Aluminium Alloy Conductors (AAAC) are extensively used for primary and secondary transmission in bare overhead distribution and transmission lines (11 kV to 800 kV lines) and HV substations. Also, usable in highly polluted industrial areas and coastal regions due to corrosion resistance.

Character: 1.Aluminum Conductor； 2.Steel Reinforced； 3.Bare.

Standard: IEC, BS, ASTM, CAN-CSA, DIN, IS, AS and relevant national and international standards.

Advantage:AAAC has good corrosion resistance, however due to the absence of steel, its resistance is lower than ACSR. AAAC can carry 15-20% extra current and has a higher life span (60 years) as compared to ACSR of equal size (30 years). The surface hardness of AAAC is 80 BHN while ACSR has hardness 35 BHN. This reduces damage to the surface during handling, thereby leading to lesser corona losses and ratio interference at EHV. AAAC can be operated with stable temperature of 85°C against ACSR conductors which are stable upto 75°C. Since AAAC has higher strength-to-weight ratio, span can be increased by 2-15% resulting in overall reduction of cost in tower supports and other accessories in the transmission line system.
