I-Resistance wire intambo ehloselwe ukwenza izinto eziphikisa ugesi (ezisetshenziselwa ukulawula inani lamanje kusekethe).Kungcono uma i-alloy esetshenzisiwe inokumelana okuphezulu, ngoba ucingo olufushane lungasetshenziswa.Ezimweni eziningi, ukuzinza kwe-resistor kubaluleke kakhulu, ngakho-ke izinga lokushisa le-alloy le-resistivity kanye nokumelana nokugqwala kudlala ingxenye enkulu ekukhetheni impahla.

Lapho ucingo lokumelana lusetshenziselwa ukushisa izinto (kuma-heaters kagesi, ama-toaster, nokunye okunjalo), ukumelana okuphezulu nokumelana ne-oxidation kubalulekile.

Kwesinye isikhathi i-resistance wire ivalwa nge-ceramic powder futhi ifakwe eshubhuni lenye ingxubevange.Izakhi ezinjalo zokushisa zisetshenziswa kuhhavini kagesi nasezishiseni zamanzi, nasemafomini akhethekile okupheka.
Intambointambo imicu eminingana yocingo lwensimbi olusontekile lwaba yi-helix eyakha "intambo" eyinhlanganisela, ephethini eyaziwa ngokuthi "intambo ebekiwe".Intambo yocingo enobubanzi obukhulu iqukethe imicu eminingi yaleyo ntambo ebekiwe ephethini eyaziwa ngokuthi “ikhebulawabekwa”.

Izintambo zensimbi zezintambo zocingo ngokuvamile zenziwe nge-non-alloy carbon steel enokuqukethwe kwekhabhoni engu-0.4 kuya ku-0.95%.Amandla aphezulu kakhulu ezintambo zezintambo enza izintambo zikwazi ukusekela amandla amakhulu aqinile futhi zigijime phezu kwezithungu ezinobubanzi obuncane kakhulu.

Kulokho okubizwa ngokuthi i-cross lay strands, izintambo zezingqimba ezihlukene ziwelana.Emicu yokulala esetshenziswa kakhulu ehambisanayo, ubude bazo zonke izendlalelo zocingo buyalingana futhi izintambo zanoma yiziphi izendlalelo ezimbili ezibekwe phezulu ziyahambisana, okuholela ekuthintaneni komugqa.Ucingo lwesendlalelo sangaphandle lusekelwa izintambo ezimbili zesendlalelo sangaphakathi.Lezi zintambo zingomakhelwane kubo bonke ubude bomucu.Izintambo ezihambisanayo zenziwa ekusebenzeni okukodwa.Ukukhuthazela kwezintambo zocingo ngalolu hlobo lwentambo kuhlala kukhulu kakhulu kunalezo (ezingavamile ukusetshenziswa) ezinezintambo eziphambanayo.Izintambo zokulala ezihambisanayo ezinezingqimba ezimbili zocingo zine-Filler yokwakha, i-Seale noma i-Warrington.

Empeleni, izintambo ezithandelayo ziyizintambo eziyindilinga njengoba zineqoqo lezingqimba zezintambo ezibekwe ngokushayisana phezu kwesikhungo okungenani ungqimba olulodwa lwezintambo olubekwe ngokuphambene nolwelwesi olungaphandle.Izintambo ezivunguzayo zingalinganiswa ngendlela yokuthi azijikelezi okusho ukuthi ngaphansi kokushuba itorque yezintambo icishe ibe nguziro.Intambo evunguzayo evulekile iqukethe izintambo eziyindilinga kuphela.Intambo yekhoyili ekhiywe uhhafu kanye nentambo yekhoyili ekhiywe ngokugcwele zihlala zinesikhungo esenziwe ngezintambo eziyindilinga.Izintambo zekhoyili ezikhiyiwe zinesendlalelo esingaphandle esisodwa noma ngaphezulu sezintambo zephrofayili.Banenzuzo yokuthi ukwakhiwa kwabo kuvimbela ukungena kokungcola namanzi ngezinga elikhulu futhi kubavikela ekulahlekelweni kwe-lubricant.Ngaphezu kwalokho, banenzuzo eyodwa ebaluleke kakhulu njengoba iziphetho zocingo lwangaphandle oluphukile lungakwazi ukushiya intambo uma inobukhulu obufanele.

Intambo eboshiwe yakhiwe inombolo yezintambo ezincane ezihlanganiswe noma ezisongwe ndawonye ukuze zenze ikhondukta enkulu.Intambo ene-stranded ivumelana nezimo kunocingo oluqinile lwengqikithi yendawo ephambanayo.I-stranded wire isetshenziswa umaukumelana okuphezuluukukhathala kwensimbi kuyadingeka.Izimo ezinjalo zihlanganisa ukuxhumana phakathi kwamabhodi wesifunda kumadivayisi webhodi le-multi-printed-circuit-board, lapho ukuqina kocingo oluqinile kuzoveza ukucindezeleka okukhulu ngenxa yokunyakaza ngesikhathi sokuhlangana noma ukusevisa;Izintambo zikagesi ze-AC zemishini;izintambo zezinsimbi zomculo;izintambo zegundane lekhompyutha;izintambo ze-electrode zokushisela;izintambo zokulawula ezixhuma izingxenye zomshini ezihambayo;izintambo zomshini wokumba;izintambo zomshini wokulandela umkhondo;nabanye abaningi.

Kumafrikhwensi aphezulu, ukuhamba kwamanje eduze nendawo yocingo ngenxa yomphumela wesikhumba, okuholela ekwenyukeni kokulahlekelwa kwamandla ocingweni.Intambo exhunywe intambo ingase ibonakale inciphisa lo mphumela, njengoba ingqikithi yendawo yonke yezintambo inkulu kunendawo yocingo oluqinile olufanayo, kodwa intambo evamile enemicu ayiwunciphisi umphumela wesikhumba ngoba zonke izintambo zifinyezwa ndawonye futhi ziziphatha kahle. njengomqhubi oyedwa.Kuzodingeka ucingo oluyintamboukumelana okuphezulukunocingo oluqinile lobubanzi obufanayo ngenxa yokuthi ingxenye enqamulayo yocingo oluboshwe akulona ithusi lonke;kukhona izikhala ezingenakugwemeka phakathi kwezintambo (lena inkinga yokupakisha imibuthano ngaphakathi kwendilinga).Intambo enezintambo ezinengxenye efanayo yekhondatha njengocingo oluqinile kuthiwa inegeji efanayo efanayo futhi ihlale ingububanzi obukhudlwana.

Kodwa-ke, ezinhlelweni eziningi zefrikhwensi ephezulu, umphumela wokusondele unzima kakhulu kunomphumela wesikhumba, futhi kwezinye izimo ezinomkhawulo, intambo elula enezintambo inganciphisa umphumela wokusondelana.Ukuze usebenze kangcono kumafrikhwensi aphezulu, intambo ye-litz, enemicu engayodwana evalekile futhi esontekile ngamaphethini akhethekile, ingasetshenziswa.
Uma izintambo zocingo ziningi kunqwaba yocingo, intambo iyagobeka kakhulu, imelana ne-kink, inganqamuki, futhi iqina kakhulu ucingo.Kodwa-ke, izintambo eziningi zandisa ubunzima bokukhiqiza kanye nezindleko.

Ngezizathu zejiyomethri, inombolo ephansi kakhulu yezintambo ngokuvamile ezibonwa ngu-7: eyodwa phakathi, kanye ne-6 eyizungezile ngokuxhumana okuseduze.Izinga elilandelayo phezulu liyi-19, okungenye ingqimba yezintambo ezingu-12 phezulu kwe-7. Ngemva kwalokho inombolo iyahlukahluka, kodwa i-37 ne-49 ijwayelekile, bese kuba yi-70 kuya ku-100 ububanzi (inombolo ayisaqondile).Ngisho nezinombolo ezinkulu kunalezo ngokuvamile zitholakala kumakhebuli amakhulu kakhulu.

Ngohlelo lokusebenza lapho ucingo luhamba khona, u-19 uphansi kakhulu okufanele usetshenziswe (u-7 kufanele usetshenziswe kuphela ezinhlelweni lapho ucingo lubekwe khona bese lunganyakazi), futhi u-49 ungcono kakhulu.Kuzinhlelo zokusebenza ezinokunyakaza okuphindaphindiwe njalo, njengamarobhothi omhlangano nezintambo ze-headphone, i-70 kuya ku-100 iyadingeka.

Kuzinhlelo zokusebenza ezidinga ukuguquguquka okwengeziwe, kusetshenziswa izintambo ezengeziwe (izintambo zokushisela ziyisibonelo esivamile, kodwa futhi nanoma yisiphi isicelo esidinga ukuhambisa ucingo ezindaweni eziqinile).Isibonelo esisodwa intambo engu-2/0 eyenziwe ngemicu engu-5,292 ye- #36 gauge wire.Izintambo zihlelwa ngokuqala ukudala inqwaba yezintambo ezingu-7.Bese eziyisi-7 zalezi zinqwaba zihlanganiswa zibe izinyanda ezinkulu.Ekugcineni kusetshenziswa izinyanda eziyi-108 ezinkulu ukwenza ikhebula lokugcina.Iqembu ngalinye lezintambo lilinyazwa ku-helix ukuze kuthi lapho ucingo lugobeka, ingxenye yenqwaba eyeluliwe izungeza i-helix iye engxenyeni ecindezelwe ukuvumela ucingo lube nokucindezeleka okuncane.
