Iingcingo kunye neentambo ziyinxalenye yenkqubo yamandla kwaye zisetyenziselwa ukuhambisa amandla ombane kunye nemiqondiso. Ngokuxhomekeke kwimeko yokusetyenziswa kunye nemeko yesicelo, kukho iindidi ezininzi zocingo kunye nekhebula. Kukho iingcingo zobhedu ezingenanto, iintambo zombane, iintambo ezigqunywe phezulu, iintambo zokulawula, iingcingo zelaphu kunye neentambo ezikhethekileyo njalo njalo.
Ukongeza kwezi ntlobo zocingo ziqhelekileyo kunye neentambo, kukho ucingo olukhethekileyo kunye nekhebula, njengocingo olunobushushu obuphezulu kunye nekhebula, i-corrosion resistant wire kunye nekhebula, i-wear-resistant wire kunye nekhebula. Ezi ngcingo kunye neentambo zineepropati ezikhethekileyo kunye nokusetyenziswa, ezifanelekileyo kwiimeko ezithile zesicelo kunye namashishini.
Ngamafutshane, ngokweendawo ezahlukeneyo zokusetyenziswa kunye neemeko zesicelo, ukukhetha uhlobo oluchanekileyo lwentambo kunye nekhebula kunokuqinisekisa ukusebenza okukhuselekileyo kunye nokuzinza kwenkqubo yamandla. Ngelo xesha, umgangatho kunye nokusebenza kokhuseleko lwentambo kunye nekhebula likwanxulumene ngokuthe ngqo nokhuseleko lwepropati yomntu, ngoko nikela ingqalelo ekukhethweni kweempawu eziqhelekileyo kunye nomgangatho othembekileyo wocingo kunye nekhebula kwinkqubo yokusetyenziswa. Oku kulandelayo kuchaza iintlobo ezininzi zocingo eziqhelekileyo kunye neentambo kunye neempawu zazo. Ndiyathemba ukukunceda uqonde ngcono intsingiselo yemodeli yenkcazo.
Uhlobo lokuqala lwentambo kunye nekhebula: ucingo olungenanto lobhedu
Ucingo olungenanto kunye neemveliso zomqhubi ongenanto zibhekisa kucingo oluqhutywayo ngaphandle kokugquma kunye nesingxobo, ikakhulu kubandakanywa ucingo olungenanto olulodwa, ucingo olungenanto kunye neprofayile ezintathu zeemveliso.
I-aluminiyam yobhedu yocingo olunye: kubandakanywa ucingo olulodwa lobhedu oluthambileyo, ucingo olulodwa lobhedu oluqinileyo, ucingo oluthambileyo lwe-aluminiyam, i-aluminiyam enzima yocingo olunye. Ikakhulu isetyenziswa njengoluhlu lweengcingo kunye neemveliso zentambo, inani elincinci lonxibelelwano kunye nokuveliswa kwezixhobo zemoto.
Ucingo olubhangileyo olungenanto: kubandakanywa ucingo oluluqilima olulubhedu (TJ), aluminiyam oluqinileyo ucingo (LJ), ialluminiyam ingxubevange yocingo olubhijelwe (LHAJ), intsimbi engundoqo yealuminiyam ucingo olubhangileyo (LGJ) lusetyenziswa ikakhulu kuqhagamshelo lwezixhobo zombane kunye nezixhobo zombane okanye amacandelo, iinkcukacha zoluhlu olusuka kwi-300mm yocingo olungaphezulu kwe-300 mm.
Uhlobo lwesibini lwentambo kunye nekhebula: intambo yamandla
Intambo yamandla kumqolo wenkqubo yamandla yokuhambisa kunye nokuhanjiswa kweemveliso zentambo yamandla aphezulu, kubandakanya i-1 ~ 330KV nangaphezulu kwamanqanaba ombane ohlukeneyo, iintambo zombane ezahlukeneyo zokufakelwa.
Icandelo ngu-1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm inombolo, 2, 5, 1, 800 mm², kunye ne-5 3+1, 3+2.
Iintambo zombane zahlulwe zaba ziintambo zombane ophantsi, iintambo zombane ophakathi, iintambo zombane ophezulu njalo njalo. Ngokweemeko zokugquma zahlulwe zibe ziintambo zeplastiki ezigqunyiweyo, iintambo ezigqunyiweyo zerabha, iintambo ezigqunywe ngamaminerali njalo njalo.
Uhlobo lwesithathu lwentambo kunye nekhebula: intambo ye-insulated overhead
Intambo ye-Overhead nayo ixhaphake kakhulu, ibonakaliswe ngokungekho ibhatyi. Abantu abaninzi banemibono emithathu ephosakeleyo ngezi ntambo. Okokuqala, abaqhubi bayo abayi-aluminium kuphela, kodwa kunye nabaqhubi bethusi (JKYJ, JKV) kunye ne-aluminium alloys (JKLHYJ). Ngoku kukwakho neentambo zentsimbi ze-aluminiyam ezixineneyo (JKLGY). Okwesibini, ayingondoqo omnye kuphela, oqhelekileyo ngokuqhelekileyo ngundoqo omnye, kodwa unokuqulunqwa ngabaqhubi abaninzi. Okwesithathu, inqanaba le-voltage yentambo ephezulu yi-35KV nangaphantsi, kungekhona kuphela i-1KV kunye ne-10KV.
Uhlobo lwesine lwentambo kunye nentambo: intambo yokulawula
Olu hlobo lwesakhiwo sekhebula kunye nekhebula lamandla lifana, libonakaliswa ngumbindi wobhedu kuphela, akukho ntambo ye-aluminium engundoqo, i-conductor cross-section encinci, inani leentsimbi lingaphezulu, njenge-24 * 1.5, 30 * 2.5 njl.
Ifanelekile kwi-AC ye-voltage ye-AC 450 / 750V nangaphantsi, izikhululo zamandla, izitishi, imigodi, amashishini e-petrochemical kunye nolunye ulawulo oluzimeleyo okanye ulawulo lwezixhobo zeyunithi. Ukuze kuphuculwe amandla okulawula ikhebula lophawu lokuthintela ukuphazamiseka kwangaphakathi nangaphandle, ukhuselo lokhuselo luyamkelwa ikakhulu.
Iimodeli eziqhelekileyo zi-KVV, KYJV, KYJV22, KVV22, KVVP. Intsingiselo yemodeli: "K" iklasi yentambo yokulawula, "V"I-PVCukugquma, “YJ”i-polyethylene edibeneyoukugquma, “V” PVC sheath, “P” ikhaka locingo lobhedu.
Kumaleko okukhusela, i-KVVP eqhelekileyo iyisikhuselo socingo lobhedu, ukuba i-copper strip shield, ibonakaliswe njenge-KVVP2, ukuba iyisikhuselo se-aluminium-plastiki ehlanganisiweyo, yi-KVVP3.
Uhlobo lwesihlanu lwengcingo kunye nentambo: Intambo ye-House Wiring Cable
Isetyenziswa kakhulu kwiikhabhathi zasekhaya kunye nokuhanjiswa, kwaye ucingo lwe-BV olusoloko lusithiwa luzezocingo lwelaphu. Iimodeli ziyi-BV, BLV, BVR, RVV, RVVP, BVVB njalo njalo.
Kwimodeli yokumelwa kocingo kunye nekhebula, i-B idla ngokubonakala, kwaye iindawo ezahlukeneyo zimela iintsingiselo ezahlukeneyo.
Ngokomzekelo, i-BVVB, isiqalo se-B yintsingiselo yocingo, kukubonisa ukuhlelwa kwesicelo sekhebula, njengokuba i-JK ithetha intambo ephezulu, i-K ithetha intambo yokulawula. I-B ekupheleni imele uhlobo olusicaba, oluyimfuno eyongezelelweyo ekhethekileyo yekhebula. Intsingiselo ye-BVVB yile: i-copper core polyvinyl chloride insulated polyvinyl chloride sheathed flat cable.
Uhlobo lwesithandathu lwentambo kunye nentambo: Ikhebula elikhethekileyo
Iintambo ezikhethekileyo ziintambo ezinemisebenzi ekhethekileyo, ingakumbi ezibandakanya iintambo ezikwaziyo ukumelana nomlilo (iZR), iintambo ezingenamsi zehalogen ezingenamsi (WDZ), iintambo ezikwaziyo ukumelana nomlilo (NH), iintambo zokuthintela uqhushumbo (FB), iintambo zokumelana neempuku kunye neentambo zokuthintela iintubi (FS), iintambo ezingangeni emanzini (ZS), njl. njl. ezifanelekileyo kumandla abalulekileyo kunye neenkqubo zolawulo.
Xa umgca udibana nomlilo, intambo inokutshisa kuphela phantsi kwesenzo somlilo wangaphandle, ubuninzi bomsi buncinci, kwaye igesi eyingozi (halogen) emsini nayo incinci kakhulu.
Xa ilangatye langaphandle linyamalala, ikhebula liyakwazi ukucima ngokwayo, ukwenzela ukuba umlilo kumzimba womntu kunye nomonakalo wepropati uncitshiswe ubuncinci. Ke ngoko, olu hlobo lwentambo lusetyenziswa kakhulu kwi-petrochemical, amandla ombane, isinyithi, izakhiwo eziphakamileyo kunye nabemi abaninzi kunye nezinye iindawo ezibalulekileyo.
Intambo ye-Refractory (NH) : ilungele ngokukodwa umbane obalulekileyo kunye neenkqubo zokulawula. Xa umgca ukwimeko yomlilo, ikhebula elikwazi ukumelana nomlilo lingamelana nobushushu obuphezulu be-750 ~ 800 ° C ngaphezu kwemizuzu engama-90 ukuqinisekisa ukuhanjiswa kwamandla okukhuselekileyo ukuphumelela ukulwa nomlilo okwaneleyo kunye nexesha lokunciphisa intlekele.
Ebusweni beziganeko ezikhethekileyo, iimveliso ezintsha zihlala zithathwa, njengeentambo ezikwazi ukumelana nomlilo, iintambo ezingatshiyo umlilo, iintambo ze-halogen ezingenalo umsi ophantsi / ophantsi-umsi ophantsi, i-termite-proof / rat-proof cables, i-oyile / ibandayo / iqondo lokushisa / intambo yokunxiba, i-radiation cross-linked cables, njl.
