Izintambo nezintambo ziyingxenye ebalulekile yesistimu yamandla futhi zisetshenziselwa ukudlulisa amandla kagesi namasignali. Ngokuya ngendawo yokusetshenziswa kanye nesimo sohlelo, kunezinhlobo eziningi zocingo nekhebula. Kukhona izintambo zethusi ezingenalutho, izintambo zikagesi, izintambo ezivaleleke phezulu, izintambo zokulawula, izintambo zendwangu kanye nezintambo ezikhethekile nokunye.
Ngokungeziwe ezinhlotsheni zezintambo ezijwayelekile ezingenhla nezintambo, kukhona izintambo ezikhethekile nekhebuli, njengentambo yezinga lokushisa eliphezulu nekhebuli, intambo nekhebuli ekwazi ukumelana nokugqwala, intambo engagugi nekhebuli. Lezi zintambo nezintambo zinezakhiwo ezikhethekile kanye nokusetshenziswa, ezifanele izimo ezithile zokufaka isicelo kanye nezimboni.
Ngamafuphi, ngokwezindawo ezihlukene zokusetshenziswa kanye nezimo zohlelo lokusebenza, ukukhetha uhlobo olulungile lwentambo nekhebula kungaqinisekisa ukusebenza okuphephile nokuzinzile kwesistimu yamandla. Ngesikhathi esifanayo, ukusebenza kwekhwalithi nokuphepha kocingo nekhebula kuhlobene ngokuqondile nokuphepha kwempahla yomuntu siqu, ngakho-ke qaphela ukukhethwa kwemikhiqizo evamile kanye nocingo oluthembekile lwekhwalithi kanye nekhebula ngesikhathi sokusebenzisa. Okulandelayo kuchaza izinhlobo ezimbalwa ezivamile zocingo nekhebula kanye nezici zazo. Ngethemba ukukusiza ukuthi uqonde kangcono incazelo yemodeli yokucaciswa.
Uhlobo lokuqala lwentambo nekhebula: intambo yethusi engenalutho
Intambo engenalutho kanye nemikhiqizo ye-conductor engenalutho ibhekisela ocingweni lwe-conductive ngaphandle kwe-insulation kanye ne-sheath, ikakhulukazi okufaka ucingo olulodwa olungenalutho, ucingo olungenalutho kanye nochungechunge lwemikhiqizo emithathu.
Ucingo olulodwa lwe-aluminium yethusi: kufaka phakathi ucingo olulodwa lwethusi oluthambile, ucingo olulodwa lwekhopha oluqinile, ucingo olulodwa oluthambile lwe-aluminium, ucingo olulodwa oluqinile lwe-aluminium. Isetshenziswa kakhulu njengemikhiqizo ehlukahlukene yocingo nekhebula, inani elincane lezintambo zokuxhumana kanye nokukhiqizwa kwemishini yemoto.
Intambo ene-stranded engenalutho: okuhlanganisa i-copper stranded wire eqinile (TJ), i-aluminium eqinile (LJ), i-aluminium alloy stranded wire (LHAJ), i-steel core aluminium stranded wire (LGJ) isetshenziselwa kakhulu ukuxhuma izinto zikagesi nezinto zikagesi noma izingxenye, imininingwane esuka kububanzi obungu-30mm obuhlukahlukene obusuka kububanzi obuyi-²000 ububanzi.
Uhlobo lwesibili lwentambo nekhebula: ikhebula lamandla
Ikhebula lamandla elisemgogodleni wesistimu yamandla yokudlulisa nokusabalalisa imikhiqizo yekhebula lamandla aphezulu, okufaka phakathi i-1 ~ 330KV nangaphezulu kwamazinga kagesi ahlukahlukene, izintambo zamandla ahlukahlukene.
Isigaba sithi 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm² inombolo, 5, 1, core inombolo 3, 3+1, 3+2.
Izintambo zikagesi zihlukaniswe zaba izintambo zamandla kagesi aphansi, izintambo zikagesi ezimaphakathi, izintambo zamandla kagesi aphezulu nokunye. Ngokwezimo zokufakwa kwe-insulation zihlukaniswe izintambo zepulasitiki ezivalekile, izintambo zenjoloba ezifakwe ngaphakathi, izintambo ezifakwe amaminerali nokunye.
Uhlobo lwesithathu lwentambo nekhebula: ikhebula elivalekile elingaphezulu
Ikhebula elingaphezulu libuye livame kakhulu, libonakala ngokungabi nejazi. Abantu abaningi banemibono emithathu eyiphutha ngalezi zintambo. Okokuqala, abaqhubi bayo abayona i-aluminium kuphela, kodwa futhi abaqhubi bethusi (JKYJ, JKV) nama-aluminium alloys (JKLHYJ). Manje sekukhona nezintambo ze-aluminium core core stranded overhead (JKLGY). Okwesibili, akuwona umgogodla owodwa kuphela, okuvamile ngokuvamile kuwumgogodla owodwa, kodwa kungabuye kwakhiwe abaqhubi abaningana. Okwesithathu, izinga le-voltage yentambo engaphezulu ngu-35KV nangaphansi, hhayi kuphela i-1KV ne-10KV.
Uhlobo lwesine lwentambo nekhebula: ikhebula lokulawula
Lolu hlobo lwesakhiwo sekhebula kanye nekhebula lamandla lufana, lubonakala ngomgogodla wethusi kuphela, akukho ntambo ye-aluminium core, i-conductor cross-section incane, inani lama-cores lingaphezulu, njenge-24 * 1.5, 30 * 2.5 njll.
Ifanele i-AC ene-voltage elinganiselwe engu-450/750V nangaphansi, iziteshi zikagesi, iziteshi ezincane, izimayini, amabhizinisi e-petrochemical kanye nezinye izilawuli ezizimele zodwa noma isilawuli semishini yamayunithi. Ukuze kuthuthukiswe ikhono lekhebula lesignali yokulawula ukuvimbela ukuphazamiseka kwangaphakathi nangaphandle, isendlalelo sokuvikela samukelwa ikakhulukazi.
Amamodeli ajwayelekile yi-KVV, KYJV, KYJV22, KVV22, KVVP. Incazelo yemodeli: “K” ikilasi lekhebula lokulawula, “V”I-PVCukwahlukanisa, “YJ”i-polyethylene ehlanganisiweukwahlukanisa, “V” PVC sheath, “P” copper wire shield.
Okwesendlalelo esivikelayo, i-KVVP evamile iyisihlangu socingo lwethusi, uma kuyisihlangu se-copper strip, sivezwa njenge-KVVP2, uma kuyi-aluminium-plastic composite tape shield, yi-KVVP3.
Uhlobo lwesihlanu lwentambo nekhebula: Ikhebula le-House Wiring
Isetshenziswa kakhulu emakhabetheni asendlini nasatshalaliswayo, kanti intambo ye-BV evame ukushiwo ingeyezintambo zendwangu. Amamodeli yi-BV, BLV, BVR, RVV, RVVP, BVVB nokunye.
Emfanekisweni wokumelwa kwentambo nekhebula, u-B uvame ukubonakala, futhi izindawo ezahlukene zimelela izincazelo ezahlukene.
Isibonelo, i-BVVB, ukuqala kwe-B incazelo yocingo, iwukukhombisa ukuhlukaniswa kwesicelo sekhebula, njengoba nje i-JK isho ikhebula elingaphezulu, i-K isho ikhebula lokulawula. U-B ekugcineni umele uhlobo oluyisicaba, okuyisidingo esikhethekile esingeziwe sekhebula. Incazelo ye-BVVB ithi: intambo eyisicaba ye-copper core polyvinyl chloride insulated polyvinyl chloride sheathed flat cable.
Uhlobo lwesithupha lwentambo nekhebula: Ikhebula elikhethekile
Izintambo ezikhethekile amakhebuli anemisebenzi ekhethekile, ikakhulukazi ahlanganisa izintambo ezivimbela amalangabi (ZR), izintambo ezingenantuthu ephansi (WDZ), izintambo ezingashi (NH), izintambo ezingaqhumisi ukuqhuma (FB), izintambo ezivikela amagundane nezintambo ezivikela umuhlwa (FS), izintambo ezingangeni emanzini (ZS), njll. kufanelekile amandla abalulekile kanye nezinhlelo zokulawula.
Lapho umugqa uhlangana nomlilo, ikhebula lingashisa kuphela ngaphansi kwesenzo somlilo wangaphandle, inani lentuthu lincane, futhi igesi eyingozi (halogen) emsini nayo incane kakhulu.
Lapho ilangabi langaphandle linyamalala, ikhebula lingakwazi nokuzicisha, ukuze umlilo emzimbeni womuntu kanye nomonakalo wempahla uncishiswe ube ubuncane. Ngakho-ke, lolu hlobo lwekhebula lusetshenziswa kabanzi ku-petrochemical, amandla kagesi, i-metallurgy, izakhiwo eziphakeme kanye nezindawo ezinabantu abaningi nezinye izindawo ezibalulekile.
Ikhebula le-Refractory (NH) : lilungele kakhulu amandla abalulekile kanye nezinhlelo zokulawula. Uma ulayini uma kusha, ikhebula elikwazi ukumelana nomlilo lingamelana nezinga lokushisa eliphakeme elingu-750~800 ° C ngaphezu kwemizuzu engama-90 ukuze kuqinisekiswe ukudluliswa kwamandla aphephile ukuze kuwine ukulwa nomlilo okwanele kanye nesikhathi sokunciphisa izinhlekelele.
Uma kubhekwa izikhathi ezikhethekile, imikhiqizo emisha itholakala njalo, njengezintambo ezingashi, izintambo ezingashi, izintambo ezingenantuthu ephansi ze-halogen ezingenantuthu ephansi, izintambo ezivikela umuhlwa/ezivikela amagundane, izintambo zikawoyela/ukubanda/ izinga lokushisa/izingagugi, izintambo ezixhunywe ngokuphambana ngemisebe, njll.
