Siyazi ukuba iintambo ezahlukeneyo zisebenza ngendlela eyahlukileyo kwaye ngenxa yoko zahlukile kwizakhiwo. Ngokubanzi, intambo yenziwa yi-conductor, i-shielding layer, i-insulation layer, i-sheath layer, kunye ne-armor layer. Ngokuxhomekeke kwiimpawu, ulwakhiwo luyahluka. Nangona kunjalo, abantu abaninzi abacaci ngomahluko phakathi kwe-insulation, i-shielding, kunye ne-sheath layers kwiintambo. Masizihlalutye ukuze siqonde ngcono.
(1) Umaleko wokuvala ubushushu
Umaleko wokwambathisa kwintambo ngokuyintloko ubonelela ngokwambathisa phakathi komqhubi kunye nendawo engqongileyo okanye ii-conductors ezikufutshane. Uqinisekisa ukuba umbane wombane, amaza e-electromagnetic, okanye imiqondiso ye-optical ethwalwa yi-conductor idluliselwa kuphela ecaleni komqhubi ngaphandle kokuvuza ngaphandle, ngelixa ikhusela izinto zangaphandle kunye nabasebenzi. Ukusebenza kokwambathisa kumisela ngokuthe ngqo i-voltage elinganisiweyo intambo enokumelana nayo kunye nobomi bayo benkonzo, nto leyo eyenza ibe yenye yezona zinto ziphambili zentambo.
Izinto zokukhusela iintambo ngokubanzi zinokwahlulwa zibe zizinto zokukhusela iintambo zeplastiki kunye nezinto zokukhusela irabha. Iintambo zamandla ezifakwe iplastiki, njengoko igama lisitsho, zineeleya zokukhusela ezenziwe ngeplastiki ekhutshiweyo. Iiplastiki eziqhelekileyo ziquka iPolyvinyl Chloride (PVC), iPolyethylene (PE),I-Polyethylene eDibeneyo (XLPE), kunye neLow Smoke Zero Halogen (LSZH). Phakathi kwazo, i-XLPE isetyenziswa kakhulu kwiintambo ze-voltage eziphakathi neziphezulu ngenxa yeempawu zayo zombane nezoomatshini ezibalaseleyo, kunye nokumelana okuphezulu kokuguga kobushushu kunye nokusebenza kwe-dielectric.
Iintambo zamandla ezifakwe irabha, kwelinye icala, zenziwe ngerabha exutywe nezinye izongezo ezahlukeneyo kwaye zicutshungulwe zibe yi-insulation. Izinto zokufakelwa irabha eziqhelekileyo ziquka imixube yendalo yerabha-styrene, i-EPDM (i-Ethylene Propylene Diene Monomer rubber), kunye nerabha ye-butyl. Ezi zinto ziguquguquka kwaye ziyanwebeka, zilungele ukuhamba rhoqo kunye ne-radius encinci egobileyo. Kwizicelo ezifana nokwemba, iinqanawa, kunye namazibuko, apho ukumelana nokukrala, ukumelana neoyile, kunye nokuguquguquka kubaluleke kakhulu, iintambo ezifakwe irabha zidlala indima engenakutshintshwa.
(2) Umaleko weSheath
Umaleko weshelufu uvumela iintambo ukuba zilungelelanise neendawo ezahlukeneyo zokusetyenziswa. Isetyenziswa phezu komaleko we-insulation, indima yayo ephambili kukukhusela iileya zangaphakathi zentambo kumonakalo woomatshini kunye nokubola kweekhemikhali, ngelixa ikwaphucula amandla oomatshini entambo, inika ukumelana nokuxinana. Ishelufu iqinisekisa ukuba intambo ikhuselekile kuxinzelelo loomatshini kunye nezinto ezingqongileyo ezifana namanzi, ukukhanya kwelanga, ukubola kwezinto eziphilayo, kunye nomlilo, ngaloo ndlela igcina ukusebenza kombane okuzinzileyo ixesha elide. Umgangatho weshelufu uchaphazela ngokuthe ngqo ubomi benkonzo yentambo.
Umaleko wesingxobo ukwabonelela ngokumelana nomlilo, ukubambezeleka komlilo, ukumelana neoyile, ukumelana ne-asidi kunye ne-alkali, kunye nokumelana ne-UV. Ngokuxhomekeke kwisicelo, iileya zesingxobo zingahlulwa zibe ziintlobo ezintathu eziphambili: iileya zesinyithi (kubandakanya isingxobo sangaphandle), iileya zerabha/zeplastiki, kunye neeleya ezidityanisiweyo. Iileya zerabha/zeplastiki kunye neeleya ezidityanisiweyo azithinteli nje kuphela umonakalo woomatshini kodwa zikwabonelela ngokuthintela amanzi, ukubambezeleka komlilo, ukumelana nomlilo, kunye nokumelana nokugqwala. Kwiimeko ezinzima ezifana nokufuma okuphezulu, iitonela ezingaphantsi komhlaba, kunye nezityalo zeekhemikhali, ukusebenza komaleko wesingxobo kubaluleke kakhulu. Izixhobo zesingxobo ezisemgangathweni ophezulu azigcini nje ngokwandisa ubomi benkonzo yekhebula kodwa zikwaphucula kakhulu ukhuseleko kunye nokuthembeka ngexesha lokusebenza.
(3) Umaleko wokukhusela
Umaleko wokukhusela kwintambo wahlulwe waba sisikhuselo sangaphakathi nesikhuselo sangaphandle. Ezi layers ziqinisekisa unxibelelwano oluhle phakathi komqhubi kunye nesikhuselo, kunye naphakathi kwesikhuselo kunye nesigqubuthelo sangaphakathi, zisusa ukwanda kobunzima bentsimi yombane yomphezulu okubangelwa yimiphezulu erhabaxa yee-conductors okanye iileya zangaphakathi. Iintambo zamandla eziphakathi kunye neziphezulu zihlala zinesikhuseli sokukhusela kunye nesikhuselo sokukhusela, ngelixa ezinye iintambo ze-low voltage zisenokungaxhotyiswa ngeeleya zokukhusela.
Ukukhusela kungaba kukukhusela okuqhuba kancinci okanye ukukhusela ngesinyithi. Iindidi eziqhelekileyo zokukhusela ngesinyithi ziquka ukusonga iteyiphu yobhedu, ukuluka ngocingo lobhedu, kunye nokusonga iteyiphu ye-aluminium foil-polyester composite tape longitudinal. Iintambo ezikhuselekileyo zihlala zisebenzisa izakhiwo ezifana nokukhusela isibini esijijekileyo, ukukhusela amaqela, okanye ukukhusela ngokubanzi. Uyilo olunjalo lubonelela ngokulahleka okuphantsi kwe-dielectric, amandla okudlulisa amandla, kunye nokusebenza okugqwesileyo kokuchasana nokuphazamiseka, okuvumela ukudluliselwa okuthembekileyo kwemiqondiso ye-analog ebuthathaka kunye nokuchasana nokuphazamiseka okunamandla kwe-electromagnetic kwiindawo zoshishino. Zisetyenziswa kakhulu ekuveliseni umbane, i-metallurgy, i-petroleum, amashishini eekhemikhali, uthutho lwesitimela, kunye neenkqubo zolawulo lwemveliso ezenzekelayo.
Ngokuphathelele izinto zokukhusela, ukhuselo lwangaphakathi ludla ngokusebenzisa iphepha elenziwe ngesinyithi okanye izinto ezihambisa kancinci, ngelixa ukhuselo lwangaphandle lunokuba nokusonga iteyipu yobhedu okanye ukuluka ucingo lobhedu. Izinto zokuluka zihlala zilubhedu olungenanto okanye ubhedu olufakwe ebhotileni, kwaye kwezinye iimeko iingcingo zobhedu ezifakwe isilivere ukuze kuphuculwe ukumelana nokugqwala kunye nokuqhuba. Isakhiwo sokukhusela esiyilwe kakuhle asiphuculi nje kuphela ukusebenza kombane kweentambo kodwa sikwanciphisa ngempumelelo ukuphazamiseka kwemitha ye-electromagnetic kwizixhobo ezikufutshane. Kwiindawo zanamhlanje ezisebenzisa umbane kakhulu nolwazi, ukubaluleka kokukhusela kuya kugqama ngakumbi.
