Ilahleko ephantsi yokuncamathelisa okuncamathelayo okudityanisiweyo ngokuthe ngqo kwi-insulated wire ephothiweyo.
Ulwakhiwo lweStrand
Iindidi ezahlukahlukeneyo zocingo oluphothiweyo zineemfano kunye nokwahluka kokusetyenziswa, izinto eziphathekayo, ulwakhiwo, oluthambileyo nolukhuni kwakunye nokubonakala (jonga kwiThebhile 2-1). Iingcingo ezingenanto zinokohlulwa zibe lucingo oluphothiweyo olungaphezulu, oluthambileyo oluphothiweyo kunye nocingo olukhethekileyo oluphothiweyo. I-Stranded core inokuthi ihlelwe kwi-core core kunye neprofayili engundoqo
I-Concentric layer stranding Esi sisakhiwo esisisiseko socingo oluphothiweyo Z. Iingcingo zodwa ezenza ucingo olubharhiweyo zijijelwe ngocwangco zijikeleze umbindi wocingo oluphothiweyo ngokwemaleko, kwaye iileya ezijijekileyo ezikufuphi zijijelwe kumacala achaseneyo. Umbindi wocingo oluphothiweyo unokuqulunqwa ngocingo olunye okanye iingcingo ezininzi. U-Z udla ngokuba lucingo olunye olungqukuva. I-Concentric layer stranding ikwabizwa ngokuba yi-tranding yesiqhelo, enezibonelelo zesakhiwo esizinzileyo, ukubonakaliswa okulula kobukhulu bejometri, kunye ne-coefficient ephantsi yokusetyenziswa kwemathiriyeli.
Nangona iingcingo zodwa ezenza i-strand nazo zijijekile kumbindi we-strand, isalathiso esijijekileyo socingo ngalunye siyafana, ngoko kunzima ukwahlula iileya, kwaye iingcingo zodwa azicwangciswanga ngokulandelelana. Esi sakhiwo sisoloko sisetyenziselwa ukuxinga kweengcingo ezibhityileyo ezinobuninzi beengcingo. Ibizwa ngokuba yi-bundle wire eyenziwa ngokudibanisa i-bundle stranding. I-Stranding ikwabizwa ngokuba yi-bunching okanye i-irregular stranding. Iinzuzo zayo kukuguquguquka okuhle, i-coefficient yokusetyenziswa kwezinto eziphezulu, kunye nokungalunganga kwayo kubume obungaqhelekanga kwaye kunzima ukubonisa imilinganiselo yejometri.
