Isicelo

Izintambo zensimbi ezenziwe ngensimbi okuhlanganisa i-Aluminium Clad Steel Conductor SC/AC zisetshenziswa kakhulu emkhakheni kagesi ukuze zisekele imithwalo yemishini.
Ukwengeza, isetshenziswa ku-Guy Wire, Overhead Ground noma Static Wire, kanye ne-Messenger Wire.

Izici

Ubuncane be-radial ukujiya obungu-5% bedayamitha yentambo iyonke busetshenziselwa ukuvala i-aluminium ensimbi enalokhu kunamathela.I-conductivity yayo ingu-20.3% IACS futhi i-UTS yayo isukela ku-1.27 kuya ku-1.34GPa.Uma kuqhathaniswa namakhondaktha enziwe ngensimbi yama-galvanized, labo abasebenzisa insimbi ye-aluminium-clad njengokuqinisa banokumelana nogesi okuphansi futhi banikeza ukumelana nokugqwala okuphezulu.

Ukupakisha

Ubude bokulethwa bunqunywa ngokucatshangelwa kwezinto ezifana nobukhulu bemigqomo ebonakalayo, izisindo zesigubhu, ubude be-span kanye nezinto zokuphatha.

Ukwakha

Izintambo zensimbi ezikhangayo ziboshelwe ngokujulile, ungqimba olungaphandle lubekwe kwesokudla bese kuthi izendlalelo ezilandelayo zibe nohlangothi oluphambene nendawo.
Ikhondaktha ingase ifake ucingo olumaphakathi olukhudlwana (i-king wire) uma kunesidingo.Ububanzi bale ntambo ngokuvamile bubukhulu ngo-5% kunezintambo eziseduze futhi busekelwe ekukhathazekeni kwedizayini yekhondatha.
