Iingcingo kunye neentambo ziyinxalenye ebalulekileyo yenkqubo yamandla kwaye zisetyenziselwa ukudlulisa amandla ombane kunye nemiqondiso. Ngokuxhomekeke kwindawo yokusetyenziswa kunye nemeko yesicelo, kukho iintlobo ezininzi zengcingo kunye neentambo. Kukho iingcingo zobhedu ezingenanto, iintambo zombane, iintambo ezigqunyiweyo ngaphezulu, iintambo zolawulo, iingcingo zelaphu kunye neentambo ezikhethekileyo njalo njalo.
Ukongeza kwiintlobo zentambo neentambo eziqhelekileyo ezingentla, kukho ezinye iingcingo kunye neentambo ezikhethekileyo, ezifana nengcingo kunye neentambo ezinobushushu obuphezulu, ingcingo kunye neentambo ezimelana nokugqwala, ingcingo kunye neentambo ezimelana nokuguguleka. Ezi ngcingo kunye neentambo zineempawu ezikhethekileyo kunye nokusetyenziswa, ezifanelekileyo kwiimeko ezithile zokusetyenziswa kunye namashishini.
Ngamafutshane, ngokweendawo ezahlukeneyo zokusetyenziswa kunye neemeko zokusetyenziswa, ukukhetha uhlobo olufanelekileyo lwentambo kunye nentambo kunokuqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kwenkqubo yamandla. Kwangaxeshanye, umgangatho kunye nokusebenza kokhuseleko lwentambo kunye nentambo kukwanxulumene ngokuthe ngqo nokhuseleko lwepropathi yomntu, ngoko ke nikela ingqalelo ekukhetheni iimpawu eziqhelekileyo kunye nentambo kunye nentambo ethembekileyo yomgangatho kwinkqubo yokusetyenziswa. Oku kulandelayo kuchaza iintlobo ezininzi zentambo kunye nentambo eziqhelekileyo kunye neempawu zazo. Ndiyathemba ukukunceda uqonde ngcono intsingiselo yemodeli yenkcazo.
Uhlobo lokuqala lwentambo kunye nentambo: ucingo lwethusi olungenanto
Iimveliso zentambo engenanto kunye neemveliso ze-conductor ezingenanto zibhekisa kwintambo eqhubayo engena-insulation kunye ne-sheath, ikakhulu kubandakanya intambo enye engenanto, intambo engenanto engenanto kunye nothotho lweemveliso ezintathu zeprofayili.
Ucingo olunye lwe-aluminium yobhedu: kubandakanya ucingo olunye lwe-copper oluthambileyo, ucingo olunye lwe-copper oluqinileyo, ucingo olunye lwe-aluminium oluthambileyo, ucingo olunye lwe-aluminium oluqinileyo. Isetyenziswa kakhulu njengeemveliso ezahlukeneyo ze-semi-products ze-wire kunye nee-cable, inani elincinci lee-wire zonxibelelwano kunye nezixhobo ze-motor.
Ucingo olungenanto olufakwe kwi-strand: kuquka ucingo oluqinileyo lwe-copper strand (TJ), ucingo oluqinileyo lwe-aluminium strand (LJ), ucingo oluqinileyo lwe-aluminium alloy strand (LHAJ), ucingo oluqinileyo lwe-aluminium strand (LGJ) lusetyenziswa kakhulu ekuqhagamshelweni kwezixhobo zombane kunye nezixhobo ze-elektroniki okanye izinto, iinkcukacha zeentambo ezahlukeneyo ezifakwe kwi-strand zingaqala kwi-1.0-300mm².
Uhlobo lwesibini lwentambo kunye nentambo: intambo yamandla
Intambo yamandla esembindini wenkqubo yamandla yokuhambisa nokusasaza iimveliso zentambo yamandla enamandla aphezulu, kuquka i-1 ~ 330KV nangaphezulu kwamanqanaba e-voltage ahlukeneyo, iintambo zamandla ezahlukeneyo zokukhusela ubushushu.
Eli candelo liyi-1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm², kwaye inani eliphambili yi-1, 2, 3, 4, 5, 3+1, 3+2.
Iintambo zombane zahlulwe zaba ziintambo ze-voltage ephantsi, iintambo ze-voltage ephakathi, iintambo ze-voltage ephezulu njalo njalo. Ngokweemeko zokwambathisa zahlulwe zaba ziintambo zeplastiki ezigqunyiweyo, iintambo zerabha ezigqunyiweyo, iintambo zeminerali ezigqunyiweyo njalo njalo.
Uhlobo lwesithathu lwentambo kunye nentambo: intambo egqunyiweyo ephezu kwentloko
Intambo engaphezulu nayo ixhaphake kakhulu, ayibonakali ngathi inejakethi. Abantu abaninzi baneengcamango ezintathu eziphosakeleyo ngezi ntambo. Okokuqala, ii-conductor zayo aziyo-aluminium kuphela, kodwa zikwayi-copper conductors (JKYJ, JKV) kunye ne-aluminium alloys (JKLHYJ). Ngoku kukwakho neentambo ze-steel core aluminum stranded overhead (JKLGY). Okwesibini, ayiyo-single core kuphela, i-common ngokubanzi yi-single core, kodwa inokwenziwa zii-conductors ezininzi. Okwesithathu, inqanaba le-voltage yentambo engaphezulu yi-35KV kwaye ngaphantsi, kungekuphela nje yi-1KV kunye ne-10KV.
Uhlobo lwesine lwentambo kunye nentambo: intambo yokulawula
Olu hlobo lwesakhiwo sentambo kunye nentambo yamandla ziyafana, ziphawulwa yi-core yobhedu kuphela, akukho ntambo ye-aluminium core, i-conductor cross-section incinci, inani lee-cores lingaphezulu, njenge-24 * 1.5, 30 * 2.5 njl.
Ifanelekile kwi-AC rated voltage 450/750V nangaphantsi, kwizikhululo zamandla, kwizikhululo ezingaphantsi, kwimigodi, kwi-petrochemical amashishini kunye nolawulo oluzimeleyo okanye lweyunithi yezixhobo. Ukuze kuphuculwe amandla entambo yesignali yokulawula ukuthintela ukuphazamiseka kwangaphakathi nangaphandle, umaleko wokukhusela usetyenziswa kakhulu.
Iimodeli eziqhelekileyo yi-KVV, KYJV, KYJV22, KVV22, KVVP. Intsingiselo yemodeli: udidi lwentambo yokulawula "K", "V"I-PVCubushushu, “YJ”i-polyethylene edibeneyoubushushu, isikhongozeli se-“V” se-PVC, isikhuselo se-“P” socingo lobhedu.
Kwi-layer yokukhusela, i-KVVP eqhelekileyo sisikhuselo sentambo yobhedu, ukuba sisikhuselo sentambo yobhedu, sichazwa njenge-KVVP2, ukuba sisikhuselo seteyiphu esidityanisiweyo esenziwe nge-aluminium-plastic, yi-KVVP3.
Uhlobo lwesihlanu lwentambo kunye nentambo: Intambo yoNxibelelwano lweNdlu
Isetyenziswa kakhulu kwiikhabhathi zasekhaya nakwiikhabhathi zokusasaza, kwaye olu cingo lwe-BV ludla ngokusetyenziswa kwiintambo zelaphu. Iimodeli zezi: i-BV, i-BLV, i-BVR, i-RVV, i-RVVP, i-BVVB njalo njalo.
Kwimodeli yokubonisa ucingo kunye nentambo, u-B udla ngokubonakala, kwaye iindawo ezahlukeneyo zimele iintsingiselo ezahlukeneyo.
Umzekelo, i-BVVB, isiqalo se-B sintsingiselo yocingo, kukubonisa udidi lwesicelo sentambo, njengokuba i-JK ithetha intambo ephezu kwentloko, i-K ithetha intambo yokulawula. I-B ekupheleni imele uhlobo oluthe tyaba, oluyimfuneko ekhethekileyo eyongezelelweyo yentambo. Intsingiselo ye-BVVB yile: intambo ethe tyaba ye-copper core polyvinyl chloride egqunywe yi-polyvinyl chloride.
Uhlobo lwesithandathu lwentambo kunye nentambo: Intambo ekhethekileyo
Iintambo ezikhethekileyo ziintambo ezinemisebenzi ekhethekileyo, ikakhulu eziquka iintambo ezithintela ilangatye (ZR), iintambo ezingenamsi ophantsi (WDZ), iintambo ezingatshiyo (NH), iintambo ezingatshiyo (FB), iintambo ezingatshiyo (FS), iintambo ezingatshiyo (ZS), njl. Intambo engatshiyo (ZR), intambo engenamsi ophantsi (WDZ): zilungele kakhulu amandla abalulekileyo neenkqubo zolawulo.
Xa umgca udibana nomlilo, intambo ingatsha kuphela xa ilangatye langaphandle lisebenza, ubungakanani bomsi buncinci, kwaye igesi enobungozi (i-halogen) emsini nayo incinci kakhulu.
Xa ilangatye langaphandle linyamalala, intambo ingazicima, ukuze umlilo emzimbeni womntu nakwimpahla uncitshiswe ube mncinci. Ke ngoko, olu hlobo lwentambo lusetyenziswa kakhulu kwi-petrochemical, kumbane, kwi-metallurgy, kwizakhiwo eziphakamileyo nakwiindawo ezinabantu abaninzi nakwezinye iindawo ezibalulekileyo.
Intambo erhabaxa (NH): ifaneleke kakhulu kwiinkqubo zamandla nolawulo ezibalulekileyo. Xa umbane utsha, intambo enganyangekiyo emlilweni inokumelana nobushushu obuphezulu obuyi-750 ~ 800 ° C ngaphezulu kwemizuzu engama-90 ukuqinisekisa ukudluliselwa kombane okukhuselekileyo ukuze kuphumelele ixesha elaneleyo lokulwa nomlilo kunye nexesha lokunciphisa iintlekele.
Xa kukho amaxesha akhethekileyo, iimveliso ezintsha zihlala zifumaneka, ezinje ngeentambo ezingatshiyo, iintambo ezingatshiyo, iintambo ezingatshiyo/ezingenamsi uphantsi, iintambo ezingatshiyo/ezingenampuku, iintambo ezingatshiyo/ezingenawo amaxolo, iintambo ezingatshiyo/ezingenawo amaxolo, iintambo ezingatshiyo/ezingenawo amaxolo, iintambo ezingatshiyo/ezingenawo amaxolo, iintambo ezidityaniswe nemitha, njl.njl.
