هادی تمام آلومینیومی (AAC)
هادی تمام آلومینیومی (AAC)، از مفتول آلومینیومی EC 1350 غیر آنیل شده ساخته می شود. این هادی به نسبت هادی های ACSR از نسبت کشش به وزن پایین تری برخوردار هستند بنابراین استفاده از این هادی سبب کاهش اسپن دکل ها شده و هزینه دکل و اجرا را افزایش می دهد.
The all aluminum conductor (AAC), is made from non-annealed EC 1350 aluminum wire. This conductor has a lower tension-to-weight ratio than ACSR conductors, so the use of this conductor reduces the span of the masts and increases the cost of the mast and implementation. If the span of the masts is not of much concern, by using this conductor instead of the ACSR conductor in the conditions of the same diameter, the electrical resistance of the conductor will decrease by 15% and the maximum allowable current will increase. AAC conductor is used in low and medium pressure lines and in electric substations. The weight per unit length of AAC conductor is less than that of ACSR conductor and more aluminum is used. The lifetime of this conductor is longer than ACSR conductor due to its higher resistance to corrosion.
Advantages of AAC conductor:
Light weight, easier installation
Increased corrosion resistance
Low current and electrical resistance
Low line operating cost
