Ngokwe-IEC60228, ii-cable conductors zahlulwe zibe ziintlobo ezine, uhlobo lokuqala, uhlobo lwesibini, uhlobo lwesihlanu, kunye nohlobo lwesithandathu.Uhlobo lokuqala luyi-conductor eqinileyo, uhlobo lwesibini luyi-conductor edibeneyo, uhlobo lokuqala kunye nesibini lujoliswe ukuba lusetyenziswe kwiintambo zokubeka ezisisigxina, uhlobo lwesihlanu kunye nesithandathu lujoliswe ukuba lusetyenziswe kwiintambo eziguquguqukayo kunye neentambo, kwaye okwesibini. uhlobo lwenzelwe abaqhubi beentambo eziguquguqukayo kunye neentambo.Isithandathu sithambile kunesihlanu.
1. Umqhubi oqinileyo:
Intsimbi yobhedu enyityilisiweyo okanye engafakwanga, i-aluminiyam engafakwanga okanye i-aluminiyam ialloy wire kwizinto zokuqhuba.
Iikhondaktha zobhedu eziqinileyo kufuneka zibe zesetyhula ezinqamlezileyo, i-25mm2 kwaye ngaphezulu kweekhondatha zobhedu eziqinileyo zenzelwe kuphela iintambo ezikhethekileyo, hayi iintambo eziqhelekileyo;Kubaqhubi abaqinileyo be-aluminium, icandelo le-16mm2 nangaphantsi liya kuba setyhula, kwi-25mm2 nangaphezulu, liya kuba setyhula kwimeko yeentambo ze-single-core, kwaye ingaba setyhula okanye ibunjwe kwimeko yeentambo ezininzi.
2. Umqhubi we-stranded:
Ukuze ukwandise ukuguquguquka okanye ukugoba kwekhebula, intambo yentambo ene-cross-section enkulu yenziwa ngokujija iingcingo ezininzi ezinobubanzi obuncinci.I-wire core ephothiweyo ngeengcingo ezininzi ezingatshatanga zinokuguquguquka okulungileyo kunye ne-curvature enkulu.Xa i-wire core igobile, iindawo zangaphakathi nangaphandle zomgca ophakathi kwentambo yocingo zinokuhamba kwaye zihlawule omnye nomnye.Xa ukugoba, akuyi kubangela ukuguqulwa kweplastiki ye-conductor, ngoko ke i-wire core ithambile.Ukusebenza kunye nokuzinza kuphuculwe kakhulu.
Ifom ye-stranding ye-core inokwahlulwa ibe yintlobo ezimbini, i-stranding rhoqo kunye ne-stranding engaqhelekanga.Inkcazo ye-stranding rhoqo kukuba: ukuxilwa kwee-conductor kunye nesiqhelo, ukugxila kunye neengqimba ezilandelelanayo kwiindlela ezahlukeneyo kubizwa ngokuba yi-stranding rhoqo.Isenokwahlulwa ibe yi-stranding eqhelekileyo kunye ne-abnormal regular stranding.Le yokugqibela ibhekisela kwi-layer-to-layer I-stranding eqhelekileyo ene-diameters yocingo eyahlukeneyo, ngelixa yangaphambili ithetha ukuba i-diameter ye-constituent wires iyafana;Ukuxinga okuthe gqolo kunokwahlulwa kube yintambo eqhelekileyo eqhelekileyo kunye neyokuxinga rhoqo.Okokugqibela kuthetha ukuba iingcingo ezenza i-stranding rhoqo azikho zodwa, kodwa zixutywe zibe yimicu ngamacingo amancinci ngokwemigaqo, kwaye emva koko ziphonswe kwii-cores., olu hlobo lokujija lusetyenziswa kakhulu ukuhambisa i-core ye-rubber insulated cable ukuphucula ukuguquguquka kwayo.I-stranded ngokungaqhelekanga (i-bundled), zonke iingcingo ezidibeneyo zijijelwe kwicala elinye.
2.1 Iikondaktara ezingqukuva ezingadityaniswanga:
Icandelo lomnqamlezo lomqhubi we-aluminium ojikelezayo ojikelezayo ngokuqhelekileyo alikho ngaphantsi kwe-10mm2.Iingcingo ezilodwa kwi-conductor kufuneka zibe ne-diameter ye-nominal efanayo, kunye nenani leengcingo ezilodwa kunye nokuxhatshazwa kwe-DC komqhubi kufuneka ahlangabezane nemigangatho.
2.2 Iikondaktara ezijikekileyo ezingqukuva kunye neekhondatha ezimile:
I-cross-section ye-conductors ye-aluminium ejikelezayo ejikelezileyo ayifanele ibe ngaphantsi kwe-16mm2, i-cross-section ye-copper edibeneyo okanye i-aluminium conductors ayifanele ibe ngaphantsi kwe-25mm2, umlinganiselo we-diameter yeengcingo ezimbini ezahlukeneyo kwi-conductor efanayo akufanele idlule i-2. , kunye nenani leengcingo ezilodwa kunye nokuxhatshazwa kwe-DC komqhubi kufuneka kuhambelane nemimiselo eqhelekileyo.
3. Ikhondaktha ethambileyo:
Iiconductors ziya kuba nepleyiti kunye nocingo lwekopha olungafakwanga.Iingcingo ezilodwa kumqhubi kufuneka zibe nedayamitha yesiqhelo efanayo, ububanzi beengcingo ezilodwa kwi-conductor akufuneki bugqithe elona xabiso liphezulu lichaziweyo, ububanzi bomqhubi wesithandathu buncinci kunolo lwesihlanu lwe-conductor ucingo olunye, kunye ne-conductor. ukuchasana akufanele kudlule ixabiso eliphezulu elichazwe kumgangatho.
