Izintambo nezintambo ziyingxenye ebalulekile yesistimu yamandla futhi zisetshenziselwa ukudlulisa amandla kagesi kanye nezibonakaliso. Kuye ngendawo yokusetshenziswa kanye nesimo sesicelo, kunezinhlobo eziningi zezintambo nezintambo. Kunezintambo zethusi ezingenalutho, izintambo zikagesi, izintambo ezifakwe ugesi ezifakwe ngaphezulu, izintambo zokulawula, izintambo zendwangu nezintambo ezikhethekile njalo njalo.
Ngaphezu kwezinhlobo ezivamile zocingo nekhebula, kunezintambo ezikhethekile nekhebula, njengocingo nekhebula lokushisa eliphezulu, ucingo nekhebula elingagqwali, ucingo nekhebula elingagugi. Lezi zintambo nezintambo zinezakhiwo ezikhethekile kanye nokusetshenziswa, ezifanele izimo ezithile zohlelo lokusebenza kanye nezimboni.
Ngamafuphi, ngokwezindawo ezahlukene zokusetshenziswa kanye nezimo zohlelo lokusebenza, ukukhetha uhlobo olufanele lwentambo nentambo kungaqinisekisa ukusebenza okuphephile nokuzinzile kohlelo lwamandla. Ngesikhathi esifanayo, ikhwalithi nokusebenza kokuphepha kwentambo nentambo nakho kuhlobene ngqo nokuphepha kwempahla yomuntu siqu, ngakho-ke naka ukukhethwa kwemikhiqizo ejwayelekile kanye nentambo nentambo yekhwalithi ethembekile enkambisweni yokusebenzisa. Okulandelayo kuchaza izinhlobo eziningana zentambo nentambo ezivamile kanye nezici zazo. Ngiyethemba ukukusiza uqonde kangcono incazelo yemodeli yokucaciswa.
Uhlobo lokuqala lwentambo nentambo: intambo yethusi engenalutho
Imikhiqizo yezintambo ezingenalutho kanye nemikhiqizo yezintambo ezingenalutho ibhekisela kuzintambo eziqhubayo ezingenayo i-insulation kanye ne-sheath, ikakhulukazi okuhlanganisa izintambo ezingenalutho, izintambo ezingenalutho kanye nemikhiqizo emithathu yochungechunge lwemikhiqizo.
Intambo eyodwa ye-aluminium yethusi: kufaka phakathi intambo eyodwa yethusi ethambile, intambo eyodwa yethusi eqinile, intambo eyodwa ye-aluminium ethambile, intambo eyodwa ye-aluminium eqinile. Isetshenziswa kakhulu njengezinhlobo ezahlukene zemikhiqizo ye-semi-products yezintambo nekhebula, inani elincane lezintambo zokuxhumana kanye nemishini yokukhiqiza.
Ucingo olungenalutho oluvaleleke ngaphakathi: okuhlanganisa ucingo oluqinile oluvaleleke ngaphakathi lwethusi (TJ), ucingo oluqinile oluvaleleke ngaphakathi lwe-aluminium (LJ), ucingo oluvaleleke ngaphakathi lwe-aluminium (LHAJ), ucingo oluvaleleke ngaphakathi lwe-aluminium (LGJ) lusetshenziswa kakhulu ekuxhumeni imishini kagesi nezinto zikagesi noma izingxenye, imininingwane yezintambo ezahlukahlukene ezivaleleke ngaphakathi isukela ku-1.0-300mm².
Uhlobo lwesibili lwentambo nentambo: intambo kagesi
Ikhebula likagesi elisemgogodla wesistimu yamandla yokudlulisa nokusatshalaliswa kwemikhiqizo yekhebula likagesi elinamandla aphezulu, okuhlanganisa amazinga e-voltage angu-1 ~ 330KV nangaphezulu, izintambo zikagesi ezahlukahlukene zokushisa.
Isigaba singu-1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm², kanti inombolo eyinhloko ingu-1, 2, 3, 4, 5, 3+1, 3+2.
Izintambo zikagesi zihlukaniswe ngamakhebula aphansi kagesi, izintambo zikagesi ophakathi, izintambo zikagesi ophakeme njalo njalo. Ngokwezimo zokushisa zihlukaniswe ngamakhebula apulasitiki afudumele, izintambo ezifakwe irabha, izintambo ezifakwe insimbi emaminerali njalo njalo.
Uhlobo lwesithathu lwentambo nentambo: intambo efakwe uthayela ngaphezulu
Ikhebula elingaphezulu nalo livame kakhulu, libonakala ngokungabi nejazi. Abantu abaningi banemibono emithathu eyiphutha ngalezi zintambo. Okokuqala, ama-conductor ayo akuzona nje i-aluminium, kodwa futhi nama-conductor ethusi (i-JKYJ, i-JKV) kanye nama-aluminium alloys (i-JKLHYJ). Manje kukhona nezintambo eziphezu kwe-aluminium core stranded (i-JKLGY). Okwesibili, akulona nje i-single core, i-common ngokuvamile i-single core, kodwa futhi ingakhiwa ama-conductor amaningana. Okwesithathu, izinga le-voltage yekhebula elingaphezulu lingu-35KV futhi ngaphansi, hhayi i-1KV kanye ne-10KV kuphela.
Uhlobo lwesine lwentambo nentambo: intambo yokulawula
Lolu hlobo lwesakhiwo sekhebula kanye nekhebula lamandla lufana, lubonakala ngomgogodla wethusi kuphela, ikhebula eliyinhloko le-aluminium alikho, ingxenye ye-conductor incane, inani lama-cores likhulu, njenge-24 * 1.5, 30 * 2.5 njll.
Ifanelekela i-voltage ekalwe yi-AC engu-450/750V nangaphansi, iziteshi zamandla, iziteshi ezincane, izimayini, amabhizinisi e-petrochemical kanye nokunye ukulawula okuzimele noma okulawulwa kwemishini yeyunithi. Ukuze kuthuthukiswe ikhono lekhebula lesignali yokulawula ukuvimbela ukuphazamiseka kwangaphakathi nangaphandle, ungqimba lokuvikela lusetshenziswa kakhulu.
Amamodeli avamile yi-KVV, KYJV, KYJV22, KVV22, KVVP. Incazelo yemodeli: isigaba sekhebula lokulawula elithi “K”, “V”I-PVCukuvikela ukushisa, “YJ”i-polyethylene exhumeneukuvikela, i-“V” PVC sheath, i-“P” copper wire shield.
Ngesendlalelo sokuvikela, i-KVVP evamile iyisivikelo sensimbi yethusi, uma iyisivikelo sentambo yethusi, ivezwa njenge-KVVP2, uma iyisivikelo setheyiphu esihlanganisiwe esenziwe nge-aluminium-plastic, yi-KVVP3.
Uhlobo lwesihlanu lwentambo nentambo: Intambo Yokuxhuma Izintambo Zendlu
Isetshenziswa kakhulu emakhabetheni asekhaya nakwabasabalalisi, futhi ucingo lwe-BV oluvame ukukhulunywa ngalo lungolwezintambo zendwangu. Amamodeli yi-BV, BLV, BVR, RVV, RVVP, BVVB njalo njalo.
Ekufanekisweni kwentambo nekhebula, u-B uvame ukubonakala, futhi izindawo ezahlukene zimelela izincazelo ezahlukene.
Isibonelo, i-BVVB, ukuqala kwe-B kusho intambo, kusho ukukhombisa ukuhlukaniswa kwesicelo sentambo, njengoba nje i-JK isho intambo engenhla, i-K isho intambo yokulawula. I-B ekugcineni imele uhlobo oluyisicaba, okuyisidingo esengeziwe esikhethekile sentambo. Incazelo ye-BVVB yile: intambo eyisicaba ye-polyvinyl chloride efakwe i-polyvinyl chloride efakwe i-sheathed flat cable.
Uhlobo lwesithupha lwentambo nentambo: Intambo ekhethekile
Izintambo ezikhethekile yizintambo ezinemisebenzi ekhethekile, ikakhulukazi ezifaka phakathi izintambo ezivimbela ilangabi (ZR), izintambo ezingenayo i-halogen enomsi ophansi (WDZ), izintambo ezingashisi umlilo (NH), izintambo ezingaqhumi (FB), izintambo ezingavimbeli amagundane kanye nezintambo ezingavimbeli umuhlwa (FS), izintambo ezingangeni manzi (ZS), njll. Intambo evimbela ilangabi (ZR), intambo engenayo i-halogen enomsi ophansi (WDZ): ifaneleka kakhulu ezinhlelweni ezibalulekile zamandla nokulawula.
Uma umugqa uhlangana nomlilo, ikhebula lingasha kuphela uma ilangabi langaphandle lisebenza, inani lentuthu lincane, kanti negesi eyingozi (i-halogen) entuthwini nayo incane kakhulu.
Uma ilangabi langaphandle linyamalala, ikhebula lingazicisha nalo, ukuze umlilo emzimbeni womuntu kanye nomonakalo wempahla uncishiswe ube mncane. Ngakho-ke, lolu hlobo lwekhebula lusetshenziswa kabanzi kumakhemikhali kagesi, amandla kagesi, i-metallurgy, izakhiwo eziphakeme kanye nezindawo ezinabantu abaningi nakwezinye izindawo ezibalulekile.
Ikhebula eliyi-refractory (NH): lifanelekela kakhulu izinhlelo zamandla nokulawula ezibaluleke kakhulu. Uma ulayini uvutha, ikhebula elingashisi umlilo lingamelana nokushisa okuphezulu okungu-750 ~ 800 ° C isikhathi esingaphezu kwemizuzu engama-90 ukuqinisekisa ukudluliswa kwamandla okuphephile ukuze kunqobe isikhathi esanele sokulwa nomlilo kanye nesikhathi sokunciphisa izinhlekelele.
Uma kubhekene nemicimbi ekhethekile, imikhiqizo emisha itholakala njalo, njengezintambo ezingashisi, izintambo ezingashisi kakhulu, izintambo ezingenayo intuthu/ezingenamusi omningi, izintambo ezingamelani nezintuthwane/ezingamelani namagundane, izintambo zikawoyela/ezibandayo/ezimelana nokushisa/ezingagugi, izintambo ezixhunywe ngemisebe, njll.
