AS 1222.2 Aluminium Clad Steel Conductor SC / AC Messenger Cable
Khuphela IINKCUKACHA ZOLUDLO
Isicelo
Imisonto yocingo lwentsimbi ekhanyisweyo kuquka i-Aluminiyam Clad Steel Conductor SC/AC isetyenziswa kakhulu kwicandelo lombane ukuxhasa imithwalo yoomatshini.
Ukongeza, isetyenziswa kwiGuy Wire, kwi-Overhead Ground okanye kwiStatic Wire, kunye nocingo lweMessenger.
Iimpawu
Ubuncinci be-radial ubukhulu be-5% yediameter yocingo iyonke isetyenziselwa ukugquma kwe-aluminiyam kwintsimbi enale ngubo.I-conductivity yayo yi-20.3% ye-IACS kunye ne-UTS yayo ukusuka kwi-1.27 ukuya kwi-1.34GPa.Xa kuthelekiswa nabaqhubi abenziwe ngetsimbi yensimbi, abo basebenzisa i-aluminium-clad steel as reinforcement banokumelana nombane ophantsi kwaye banikeze ukuxhathisa okuphezulu kwe-corrosion.
Ukupakisha
Ubude bokuhanjiswa bumiselwa ngokuqwalaselwa kwezinto ezifana nemilinganiselo yegubu, ubunzima begubu, ubude bexesha kunye nesixhobo sokuphatha.
Ukwakhiwa
Iingcingo zentsimbi ezenziwe ngegalvanized zibotshelelwe ngokuthe ngqo, kwaye umaleko ongaphandle ubekwe ngesandla sasekunene kwaye iileyiti ezilandelayo zinecala elichaseneyo.
Ikhondaktha inokufaka ucingo olusembindini omkhulu (ucingo lwenkosi) ukuba kuyimfuneko.Olu cingo lwedayamitha luqhele ukuba likhulu nge-5% kuneengcingo ezikufutshane kwaye lusekwe kwiinkxalabo zoyilo lwe-conductor.
