هادي هاي تمام آلومينيوم AAC (All Aluminum Conductor) از رشته هاي آلومينيومي EC-1350 غير آنيل تشکيل شده که با مقطع دايره ايي حول يک سيم مرکزي تابيده شده اند.اين هادي ها در طراحي خطوط فشار متوسط و ضعيف زماني که پارامترهايي همچون استحکام کششي بالا مد نظر نباشد و همچنين فاصله ميان دکلها کوتاه باشد، مورد استفاده قرار ميگيرد. از مزاياي اين هادي ها مي توان به افت ولتاژ پايين نسبت به انواع ديگر هادي ها و وزن کم در واحد طول و نصب راحت يراق آلات آن اشاره کرد که آن را از نظر اقتصادي به صرفه و استفاده از آن را راحت تر ميکند . به علاوه ساختار تمام آلومينيومي در AAC سبب مي شود که مقاومت کابل در برابر خوردگي افزايش يابد

Concentric lay stranded Aluminium Conductor ( AAC) is made up of one or more strands of hard drawn 1350 aluminum alloy. These conductors are used in low, medium and high voltage overhead lines. AAC has seen extensive use in urban areas where spans are usually short but high conductivity us required. The excellent corrosion resistance of aluminium has made AAC a conductor of choice in coastal areas. Because of its relatively poor strength to weight ratio, AAC had limited use in transmission lines and rural distribution because of long spans utilized. All aluminium conductors are made up of one or more strands of aluminium wire dep.
