Insimbi eqinisiwe yomqhubi we-ACSR noma i-aluminium conductor isetshenziswa njengokudlulisa okungenalutho phezulu kanye nekhebula lokusabalalisa eliyinhloko nelesibili. Imicu yangaphandle iyi-aluminium ehlanzekile kakhulu, ekhethwe ngenxa yokuqhuba kwayo okuhle, isisindo esiphansi, izindleko eziphansi, ukumelana nokugqwala kanye nokumelana okuhle kokucindezeleka komshini. Umucu ophakathi uyinsimbi yamandla engeziwe ukusiza ukusekela isisindo somqhubi. Insimbi inamandla aphezulu kune-aluminium okuvumela ukucindezelwa okukhulu komshini ukuthi kusetshenziswe kumqhubi. Insimbi iphinde ibe nokuguquguquka okuphansi kokunwebeka nokunganwebeki (ukuphakama okuhlala njalo) ngenxa yokulayisha komshini (isb. umoya neqhwa) kanye ne-coefficient ephansi yokwanda kokushisa ngaphansi kokulayisha kwamanje. Lezi zakhiwo zivumela i-ACSR ukuthi ihlehle kancane kakhulu kunabaqhubi be-all-aluminium. Ngokwe-International Electrotechnical Commission (IEC) kanye ne-CSA Group (eyayikade iyi-Canadian Standards Association noma i-CSA) yokuqamba amagama, i-ACSR ibizwa ngokuthi i-A1/S1A.
Ingxubevange ye-aluminium kanye nesimo sezulu esisetshenziswa emicu yangaphandle e-United States naseCanada ngokuvamile kuba ngu-1350-H19 kanti kwezinye izindawo kuba ngu-1370-H19, ngayinye inokuqukethwe kwe-aluminium okungu-99.5+%. Isimo sezulu se-aluminium sichazwa yisijobelelo senguqulo ye-aluminium, esinzima kakhulu uma kubhekwa i-H19. Ukuze kwandiswe impilo yenkonzo yemicu yensimbi esetshenziselwa umongo womqhubi, ngokuvamile igqunywa nge-zinc ukuze kuvinjelwe ukugqwala. Ububanzi bemicu esetshenziswa kokubili imicu ye-aluminium kanye nensimbi buyahlukahluka kubaqhubi be-ACSR abahlukene.
Ikhebula le-ACSR lisancike emandleni okudonsa e-aluminium; liqiniswa yinsimbi kuphela. Ngenxa yalokhu, izinga lokushisa layo lokusebenza eliqhubekayo lilinganiselwe ku-75 °C (167 °F), izinga lokushisa lapho i-aluminium iqala khona ukuthamba nokuthamba ngokuhamba kwesikhathi. Ezimweni lapho kudingeka khona amazinga okushisa aphezulu okusebenza, i-aluminium-conductor steel-supported (ACSS) ingasetshenziswa
Ukubekwa komqhubi kunqunywa ngeminwe emine enwetshiwe; isiqondiso "sokudla" noma "sesobunxele" sokubekwa kunqunywa kuye ngokuthi sihambisana yini nesiqondiso somunwe kusuka esandleni sokudla noma sesobunxele ngokulandelana. Ama-aluminium angaphezulu (AAC, AAAAC, ACAR) kanye nama-ACSR conductor e-USA ahlala ekhiqizwa ngesendlalelo somqhubi wangaphandle esinokubekwa kwesandla sokudla. Uma sibheke phakathi, isendlalelo ngasinye sinezingqimba ezishintshanayo. Ezinye izinhlobo zama-conductor (isb. i-copper overhead conductor, i-OPGW, i-steel EHS) zihlukile futhi zinesendlalelo sokhohlo kumqhubi wangaphandle. Amanye amazwe aseNingizimu Melika achaza ukubekwa kwesandla sobunxele kwesendlalelo somqhubi wangaphandle ku-ACSR yawo, ngakho-ke lawo ahlukaniswe ngendlela ehlukile kunalawo asetshenziswa e-USA.
I-ACSR eyenziwe yithi ingahlangabezana nezindinganiso ze-ASTM, AS, BS, CSA, DIN, IEC, NFC njll.
