Hoʻohana ʻia ke alakaʻi ACSR a i ʻole ke kila alakaʻi alumini i hoʻoikaika ʻia ma ke ʻano he hoʻoili ʻōlohelohe ma luna a ma ke ʻano he kaula hoʻokaʻawale mua a me ka lua. ʻO nā kaula waho he alumini maʻemaʻe kiʻekiʻe, i koho ʻia no kona conductivity maikaʻi, ke kaumaha haʻahaʻa, ke kumukūʻai haʻahaʻa, ke kū'ē i ka pala a me ke kūpaʻa mechanical kūpono. ʻO ke kaula waena he kila no ka ikaika hou e kōkua i ke kākoʻo ʻana i ke kaumaha o ke alakaʻi. ʻOi aku ka ikaika o ke kila ma mua o ka alumini e hiki ai ke hoʻonui ʻia ka tension mechanical ma luna o ke alakaʻi. Loaʻa i ke kila ka deformation elastic a me ka inelastic haʻahaʻa (elongation mau) ma muli o ka ukana mechanical (e like me ka makani a me ka hau) a me ka coefficient haʻahaʻa o ka hoʻonui ʻana o ka thermal ma lalo o ka ukana o kēia manawa. ʻAe kēia mau waiwai iā ACSR e sag emi ma mua o nā alakaʻi alumini āpau. Wahi a ka International Electrotechnical Commission (IEC) a me ka ʻaha kūkā inoa ʻo The CSA Group (ma mua ʻo Canadian Standards Association a i ʻole CSA), ua kapa ʻia ʻo ACSR ʻo A1/S1A.
ʻO ka alumini me ka mahana i hoʻohana ʻia no nā kaula waho ma ʻAmelika Hui Pū ʻIa a me Kanada he 1350-H19 maʻamau a ma nā wahi ʻē aʻe he 1370-H19, kēlā me kēia me 99.5+% ka nui o ka alumini. Hoʻākāka ʻia ka mahana o ka alumini e ka hopena o ka mana alumini, ʻo ia hoʻi ma ke ʻano o H19 he paʻakikī loa. No ka hoʻolōʻihi ʻana i ke ola lawelawe o nā kaula kila i hoʻohana ʻia no ke kumu alakaʻi, ua galvanized pinepine ʻia lākou, a i ʻole i uhi ʻia me ka zinc e pale aku i ka pala. ʻOkoʻa nā anawaena o nā kaula i hoʻohana ʻia no nā kaula alumini a me ke kila no nā alakaʻi ACSR like ʻole.
Ke hilinaʻi nei ke kaula ACSR i ka ikaika tensile o ka alumini; hoʻoikaika wale ʻia e ke kila. Ma muli o kēia, ua kaupalena ʻia kona mahana hana mau i 75 °C (167 °F), ʻo ia ka mahana e hoʻomaka ai ka alumini e anneal a palupalu i ka hala ʻana o ka manawa. No nā kūlana kahi e pono ai nā mahana hana kiʻekiʻe, hiki ke hoʻohana ʻia ke kākoʻo kila alumini-conductor (ACSS).
Hoʻoholo ʻia ke kau ʻana o kahi alakaʻi e nā manamana lima ʻehā i hoʻolōʻihi ʻia; hoʻoholo ʻia ke kuhikuhi "ʻākau" a "hema" paha o ke kau ʻana ma muli o ke kūlike o ke kuhikuhi manamana lima mai ka lima ʻākau a i ʻole ka lima hema. Hana mau ʻia nā alakaʻi alumini ma luna (AAC, AAAC, ACAR) a me ACSR ma USA me ka papa alakaʻi waho me kahi kau ʻākau. Ke hele nei i ke kikowaena, loaʻa i kēlā me kēia papa nā kau ʻē aʻe. He ʻokoʻa kekahi mau ʻano alakaʻi (e like me ke alakaʻi keleawe ma luna, OPGW, kila EHS) a he kau hema ma ke alakaʻi waho. Kuhikuhi kekahi mau ʻāina ʻAmelika Hema i ka kau hema no ka papa alakaʻi waho ma kā lākou ACSR, no laila ua ʻoki ʻokoʻa ʻia kēlā mau mea ma mua o nā mea i hoʻohana ʻia ma USA.
Hiki i ka ACSR i hana ʻia e mākou ke hālāwai me ASTM, AS, BS, CSA, DIN, IEC, NFC a pēlā aku.
