Ukuze kuvikelwe ubuqotho besakhiwo kanye nokusebenza kukagesi kwezintambo nokwandisa isikhathi sazo sokusebenza, ungqimba lwezivikelo lungangezwa engxenyeni engaphandle yekhebula. Ngokuvamile kunezinhlobo ezimbili zezivikelo zekhebula:iteyipu yensimbiizikhali kanyeucingo lwensimbiisivikelo.
Ukuze izintambo zikwazi ukumelana nokucindezela kwe-radial, kusetshenziswa i-tape yensimbi ephindwe kabili enenqubo yokugoqa izikhala—lokhu kwaziwa ngokuthi ikhebula elivikelwe nge-steel tape. Ngemva kokufaka izintambo, ama-tape ensimbi azungezwa ngaphakathi kwe-cable, kulandelwe ukukhishwa kwe-sheath yepulasitiki. Amamodeli ekhebula asebenzisa lesi sakhiwo afaka izintambo zokulawula ezifana ne-KVV22, izintambo zikagesi ezifana ne-VV22, kanye nezintambo zokuxhumana ezifana ne-SYV22, njll. Izinombolo ezimbili zesi-Arabhu ohlotsheni lwekhebula zibonisa okulandelayo: u-“2” wokuqala umele i-tape yensimbi ephindwe kabili; u-“2” wesibili umele i-PVC (Polyvinyl Chloride) sheath. Uma kusetshenziswa i-PE (Polyethylene) sheath, inombolo yesibili ishintshwa ibe ngu-“3”. Izintambo zalolu hlobo zivame ukusetshenziswa ezindaweni ezinomfutho ophezulu, njengokuwela imigwaqo, ama-plaza, izindawo ezivame ukudlidliza eceleni komgwaqo noma ezindaweni eziseceleni kwesitimela, futhi zifanelekela ukungcwaba ngqo, imigudu, noma ukufakwa kwe-conduit.
Ukuze kusizwe izintambo zikwazi ukumelana nokucindezeleka okuphezulu kwe-axial, izintambo eziningi zensimbi ezinekhabhoni ephansi zigoqwa ngokujikeleza ingaphakathi lekhebula—lokhu kwaziwa ngokuthi ikhebula elivikelwe ngentambo yensimbi. Ngemva kokufakwa kwezintambo, izintambo zensimbi zigoqwa ngephimbo elithile bese kufakwa igobolondo phezu kwazo. Izinhlobo zekhebula ezisebenzisa lokhu kwakhiwa zifaka izintambo zokulawula ezifana ne-KVV32, izintambo zikagesi ezifana ne-VV32, kanye nezintambo ze-coaxial ezifana ne-HOL33. Izinombolo ezimbili zesi-Arabhu kumodeli zimelela: u-“3” wokuqala ubonisa izikhali zensimbi; u-“2” wesibili ubonisa igobolondo le-PVC, kanye no-“3” ubonisa igobolondo le-PE. Lolu hlobo lwekhebula lusetshenziswa kakhulu ekufakweni kwesikhathi eside noma lapho kukhona ukwehla okukhulu okuqondile.
Umsebenzi Wezintambo Ezihlomile
Izintambo ezivikelwe zibhekisela ezintanjeni ezivikelwe ungqimba lwensimbi. Inhloso yokwengeza izintambo akusikho nje ukukhulisa amandla okubamba nokucindezela kanye nokwandisa ukuqina kwemishini, kodwa futhi nokuthuthukisa ukumelana nokuphazamiseka kwe-electromagnetic (EMI) ngokuvikela.
Izinto zokuzivikela ezivamile zifaka phakathi i-steel tape, i-steel wire, i-aluminium tape, kanye ne-aluminium tube. Phakathi kwazo, i-steel tape kanye ne-steel wire zine-magnetic permeability ephezulu, zinikeza imiphumela emihle yokuvikela i-magnetic, ikakhulukazi esebenza kahle ekuphazamisekeni kwemvamisa ephansi. Lezi zinto zivumela ikhebula ukuthi limbozwe ngqo ngaphandle kwemigudu, okwenza libe yisisombululo esingabizi kakhulu nesisetshenziswa kabanzi.
Ingqimba yezivikelo ingasetshenziswa kunoma yisiphi isakhiwo sekhebula ukuthuthukisa amandla omshini kanye nokumelana nokugqwala, okwenza kube kuhle ezindaweni ezivame ukulimala ngomshini noma ezindaweni ezinzima. Ingabekwa nganoma iyiphi indlela futhi ifaneleka kakhulu ekungcwatshweni okuqondile ezindaweni ezinamadwala. Kalula nje, izintambo ezivikelwe ziyizintambo zikagesi ezenzelwe ukusetshenziswa ezingcwatshwe noma ezingaphansi komhlaba. Ngezintambo zokudlulisa amandla, isivikelo sengeza amandla okubamba nokucindezelwa, sivikela ikhebula emandleni angaphandle, futhi sisize ngisho nokumelana nomonakalo wegundane, sivimbele ukuhlafuna isivikelo esingaphazamisa ukudluliselwa kwamandla. Izintambo ezivikelwe zidinga irediyasi enkulu yokugoba, futhi ungqimba lwezivikelo lungabekwa phansi ukuze kuphephe.
I-ONE WORLD Ikhethekile Ngezinto Zokusetshenziswa Kwekhebula Ezisezingeni Eliphezulu
Sinikeza uhla oluphelele lwezinto zokuphepha—kufaka phakathi i-steel tape, i-steel wire, kanye ne-aluminium tape—ezisetshenziswa kabanzi kokubili kuma-fiber optic kanye nama-power cables ukuze kuvikelwe isakhiwo kanye nokusebenza okuthuthukisiwe. Isekelwa ulwazi olubanzi kanye nesistimu yokulawula ikhwalithi eqinile, i-ONE WORLD izibophezele ekuhlinzekeni ngezixazululo zezinto ezithembekile nezihambisanayo ezisiza ekuthuthukiseni ukuqina nokusebenza okuphelele kwemikhiqizo yakho yekhebula.
Zizwe ukhululekile ukuxhumana nathi ukuthola ulwazi olwengeziwe ngomkhiqizo kanye nokusekelwa kobuchwepheshe.
