Amasethingi Okugqwala noma Asogwini: Ngenxa yokuthi amakhondatha e-AAAC amelana nokugqwala, angasetshenziselwa izintambo zokudlulisela ezindaweni eziswakeme, ezisogwini noma kwezinye izilungiselelo lapho izinto ezibolayo zikhona.Amakhondaktha e-AAAC anokumelana nokugqwala okukhulu kunamakhondaktha avamile we-aluminium ngenxa yengxubevange ye-aluminium esetshenziswa kuzo.
4. Ukuthuthukisa Olayini Bamanje Bakagesi: Amakhondaktha e-AAAC angase asetshenziswe ngezikhathi ezithile ukuze kuthuthukiswe izintambo zamanje zokuthumela.Izinsiza zingathuthukisa umthamo, zinciphise ukulahleka kwamandla, futhi zithuthukise ukusebenza kolayini ngokushintshanisa amakhondaktha amadala amakhondaktha e-AAAC.
Kubalulekile ukukhumbula ukuthi uhlobo lwekhondatha olunembile olukhethiwe luzoncika enanini lezinto eziguquguqukayo, okuhlanganisa njengezidingo zesistimu yamandla, indawo ezungezile, isabelomali, kanye nomklamo wolayini wokudlulisela.Lokhu okuguquguqukayo kuhlolwa yizinsiza kanye nonjiniyela ukuze kuhlonzwe umqhubi ongcono kakhulu wephrojekthi yolayini wokudlulisa.
Izinhlobo ezimbili ezihlukene zamakhondatha zisetshenziswa ezinhlelweni zokudlulisela nokusabalalisa amandla aphezulu: I-AAAC (Yonke I-Aluminium Alloy Conductor) ne-ACSR (I-Aluminium Conductor Steel Reinforced).Umehluko oyinhloko phakathi kwe-ACSR ne-AAAC imi kanje:
1. Ukwakhiwa: Amakhondaktha e-ACSR ahlanganisa ingqikithi emaphakathi yezintambo zensimbi ezizungezwe isendlalelo esisodwa noma eziningi zezintambo ze-aluminium.I-conductor iqiniswa futhi isekelwe ngomshini umgogodla wensimbi.Ngakolunye uhlangothi, abaqhubi be-AAAC bahlanganisa kuphela i-aluminium alloy.Azikho izintambo zensimbi kuzo.
2. Amandla Emishini: Ama-conductor e-ACSR anamandla aqinile okuqina namandla emishini uma kuqhathaniswa namakhondaktha e-AAAC ngenxa yomgogodla wensimbi.Ngenxa yokwesekwa okwengeziwe okunikezwa izintambo zensimbi, abaqhubi be-ACSR bangakwazi ukuthwala imithwalo emikhulu njengeqhwa nomoya.
3. I-Electrical Conductivity: Ngokuvamile, abaqhubi be-AAAC basebenza ngogesi kakhulu kunabaqondisi be-ACSR.Ngosayizi onikeziwe, amakhondaktha e-AAAC angathwala amanje kakhulu ngoba i-aluminium inokuqhutshwa okungcono kunensimbi.
4. Isisindo: Ngenxa yokuthi amakhondaktha e-AAAC awaqukethe insimbi, anesisindo esingaphansi kwamakhondatha e-ACSR.Ngenxa yokuthi amakhondaktha e-AAAC anesisindo esingaphansi, ukufakwa kungase kube lula futhi izindleko zokuhamba zingase zibe phansi.
5. Isicelo: Lapho amandla emishini ephezulu edingeka khona, njengakumalayini okudlulisela amabanga amade noma izifunda ezineqhwa elibalulekile nomoya, amakhondatha e-ACSR asetshenziswa kaningi emigqeni yokudluliswa kwamandla aphezulu.Ngokuphambene, imigqa yokusabalalisa nezinye izindawo ezidinga i-conductor engasindi enamandla okusebenza kagesi ngokuvamile zisebenzisa amakhondaktha e-AAAC.
Kubalulekile ukukhumbula ukuthi ukukhetha uhlobo lwekhondatha olulungile kuncike enanini lezinto eziguquguqukayo, okuhlanganisa izici zomthwalo, ibanga lokudlulisela, ukucatshangelwa kwemvelo, kanye nezidingo ezikhethekile zesistimu yamandla.Lokhu okuguquguqukayo kucatshangelwa onjiniyela nezinsiza lapho benquma phakathi kwamakhondakta we-ACSR kanye ne-AAAC ngohlelo olunikeziwe.
Uhlobo lwekhondatha kagesi olusetshenziswa kumasistimu okudlulisa amandla aphezulu kanye nokusabalalisa lubizwa ngokuthi "i-AAAC conductor".Igama elithi AAAC limele "All Aluminium Alloy Conductor."
Izintambo ze-aluminium alloy zakha umnyombo wamakhondatha we-AAAC, azungezwe ungqimba olulodwa noma eziningi zezintambo ezakhiwe nge-alloy efanayo.Uma kuqhathaniswa namakhondaktha avamile we-aluminium, isilinganiso esiphezulu samandla nesisindo sengxubevange ye-aluminium esetshenziswa kumakhondaktha e-AAAC senza amandla emishini aphezulu kanye nokumelana nokucwila.
Ezimweni lapho isisindo esiphansi namandla aqine kakhulu abalulekile, njengemigqa yokudlulisa yesikhathi eside noma izifunda ezinomoya obalulekile olayishwayo neqhwa, amakhondakta we-AAAC asetshenziswa njalo.Banikeza izinzuzo ezifana nokukhuphuka kwe-conductivity, ukunciphisa ukulahlekelwa kwamandla, nezindleko eziphansi zokufaka ngenxa yesisindo sabo esincane.
Nakuba umkhiqizi kanye nokusetshenziswa okuhlosiwe kungase kube nomthelela efomini elinembile nezici zamakhondatha we-AAAC, ngokuvamile enziwa ukuthi ahambisane namazinga embonini kanye nezimfuneko zokudluliswa kukagesi namasistimu okusabalalisa.
