Kubalulekile ukukhumbula ukuba uhlobo lomqhubi oluchanekileyo olukhethiweyo luya kuxhomekeka kwinani lezinto eziguquguqukayo, ezibandakanya njengeemfuno zenkqubo yamandla, indawo engqongileyo, uhlahlo lwabiwo-mali, kunye noyilo lwentambo yothumelo.Ezi ziguquguqukayo zivavanywa ngezinto eziluncedo kunye neenjineli ukuchonga oyena umqhubi weprojekthi enikiweyo yomzila wothumelo.
Iintlobo ezimbini ze-conductor ezihlukeneyo zisetyenziselwa ukuhanjiswa kwamandla kunye nokuhanjiswa kwamandla aphezulu: i-AAAC (Yonke i-Aluminium Alloy Conductor) kunye ne-ACSR (i-Aluminium Conductor Steel Reinforced).Ulwahlulo oluphambili phakathi kwe-ACSR kunye ne-AAAC lulandelayo:
1. Ukwakhiwa: Abaqhubi be-ACSR baquka i-core central of ingcingo zetsimbi ezijikeleze enye okanye ngaphezulu kweengcingo ze-aluminium.I-conductor iqiniswa kwaye ixhaswa ngomatshini yintsimbi yentsimbi.Ngokwahlukileyo, abaqhubi be-AAAC baquka kuphela i-aluminium alloy.Akukho ingcingo zentsimbi kuzo.
2. Amandla omatshini: Abaqhubi be-ACSR banamandla aqinile kunye namandla omatshini xa kuthelekiswa nabaqhubi be-AAAC ngenxa yentsimbi yentsimbi.Ngenxa yenkxaso eyongezelelweyo enikwa iintambo zentsimbi, abaqhubi be-ACSR banokunyamezela imithwalo emikhulu yomatshini efana nomkhenkce nomoya.
3. Ukuhanjiswa koMbane: Ngokuqhelekileyo, abaqhubi be-AAAC baqhuba umbane ngaphezu kwabaqhubi be-ACSR.Ngobungakanani obunikeziweyo, abaqhubi be-AAAC banokuthwala ngoku ngakumbi kuba i-aluminium ine-conductivity engcono kunentsimbi.
4. Ubunzima: Ngenxa yokuba abaqhubi be-AAAC abanalo isinyithi, balinganisa ngaphantsi kwabaqhubi be-ACSR.Ngenxa yokuba iikondakta ze-AAAC zinobunzima obuncinci, ukufakela kunokuba lula kwaye iindleko zothutho zinokuba sezantsi.
5. Isicelo: Apho amandla omatshini aphezulu afuneka, njengakwiintambo zothumelo lomgama omde okanye iingingqi ezinomkhenkce obalulekileyo kunye nomthwalo womoya, ii-conductor ze-ACSR zisetyenziswa rhoqo kwiintambo zothumelo lwamandla aphezulu.Ngokwahlukileyo, imigca yokuhambisa kunye nezinye iindawo ezifuna i-conductor ekhaphukhaphu ene-conductivity enamandla yombane ihlala iqesha abaqhubi be-AAAC.
Kubalulekile ukukhumbula ukuba ukukhetha uhlobo lomqhubi oluchanekileyo kuxhomekeke kwinani lezinto eziguquguqukayo, kubandakanywa iimpawu zomthwalo, umgama wothumelo, uqwalaselo lokusingqongileyo, kunye neemfuno ezizodwa zenkqubo yamandla.Ezi ziguquko zithathelwa ingqalelo yinjineli kunye nezixhobo xa zithatha isigqibo phakathi kwe-ACSR kunye nabaqhubi be-AAAC kwisicelo esinikezelweyo.
Uhlobo lwe-conductor yombane olusetyenziswa kwi-overhead power transmission and distribution systems lubizwa ngokuba yi-"AAAC conductor".Isishunqulelo se-AAAC simele "Yonke i-Aluminium Alloy Conductor."
Imicu ye-aluminium ye-alloy yenza i-core ye-AAAC conductors, ejikelezwe ngocingo olunye okanye ngaphezulu kweengcingo ezenziwe nge-alloy efanayo.Xa kuthelekiswa nabaqhubi be-aluminium abaqhelekileyo, umlinganiselo ophezulu wamandla-kubunzima be-alloy ye-alloy esetyenziswa kwii-AAAC conductors yenza amandla omatshini aphezulu kunye nokumelana ne-sag.
Kwiimeko apho ubunzima obuphantsi kunye nokuqina okuphezulu kokuqina kubaluleke kakhulu, njengemigca yokuhambisa ixesha elide okanye imimandla enomoya obalulekileyo kunye nokulayisha umkhenkce, iikhondaktha ze-AAAC zihlala zisetyenziswa.Banika izibonelelo ezifana nokunyuka kwe-conductivity, ukunciphisa ilahleko yamandla, kunye neendleko eziphantsi zokufakela ngenxa yobunzima babo obuncinci.
Nangona umenzi kunye nokusetyenziswa okucetywayo kunokuba neempembelelo kwifomu echanekileyo kunye neempawu ze-AAAC conductors, ngokuqhelekileyo zenziwa ukuba zihambelane nemigangatho yoshishino kunye neemfuno zokuhambisa umbane kunye neenkqubo zokuhambisa.
