Ngokusho kwe-IEC60228, ama-cable conductors ahlukaniswe abe izinhlobo ezine, uhlobo lokuqala, uhlobo lwesibili, uhlobo lwesihlanu, nohlobo lwesithupha.Uhlobo lokuqala luyi-conductor eqinile, uhlobo lwesibili luyi-conductor eboshiwe, uhlobo lokuqala nolwesibili luhloselwe ukusetshenziselwa izintambo zokubeka ezingaguquki, uhlobo lwesihlanu nolwesithupha luhloselwe ukusetshenziselwa izintambo eziguquguqukayo nezintambo, kanti okwesibili. uhlobo lwenzelwe abaqhubi bezintambo eziguquguqukayo nezintambo.Isithupha sithambile kunesihlanu.
1. Umqhubi oqinile:
I-metallized noma i-annealed wire yethusi, i-aluminium engagcotshiwe noma i-aluminium alloy wire yezinto zekhondatha.
Amakhondaktha ethusi aqinile kufanele abe yindilinga ephambanayo, amakhondatha angu-25mm2 nangaphezulu ahloselwe izintambo ezikhethekile kuphela, hhayi izintambo ezivamile;Kumakhondaktha e-aluminium aqinile, isigaba esingu-16mm2 nangaphansi sizoba yindilinga, ku-25mm2 nangaphezulu, sizoba yindilinga endabeni yezintambo eziwumgogodla owodwa, futhi singase sibe isiyingi noma silolonge esimweni sezintambo ezinamanzika amaningi.
2. Umqhubi we-stranded:
Ukuze kwandiswe ukuguquguquka noma ukugoba kwekhebula, umgogodla wekhebula onesiphambano esikhulu sakhiwe ngokusonteka izintambo eziningi ezingabodwa ezinobubanzi obuncane.I-wire core esontelwe izintambo eziningi ezizodwa inokuguquguquka okuhle nokugoba okukhulu.Uma i-wire core igobile, izingxenye zangaphakathi nezingaphandle zomugqa omaphakathi wenkambo yocingo zinganyakaza futhi zikhokhelane.Lapho ukugoba, ngeke kubangele ukuguqulwa kwepulasitiki komqhubi, ngakho-ke umgogodla wocingo uthambile.Ukusebenza nokuzinza kuthuthukiswa kakhulu.
Ifomu le-stranding of the core lingahlukaniswa libe izinhlobo ezimbili, i-stranding evamile kanye ne-stranding engavamile.Incazelo ye-stranding ejwayelekile yilena: ukudonsa kwamakhondatha ngokujwayelekile, ukugxila kanye nezingqimba ezilandelanayo ezindaweni ezihlukene kubizwa ngokuthi i-tranding ejwayelekile.Ingabuye ihlukaniswe ibe i-stranding evamile evamile kanye ne-stranding evamile engavamile.Lokhu kwakamuva kubhekise ku-lay-to-layer I-stranding evamile enobubanzi bezintambo ezihlukene, kanti eyokuqala isho ukuthi ububanzi bezintambo ezihlanganisiwe zonke ziyefana;I-stranding evamile ingabuye ihlukaniswe ibe i-stranding evamile evamile kanye ne-compound evamile.Lokhu kokugcina kusho ukuthi izintambo ezakha i-stranding evamile azizona zodwa, kodwa zisontekile zibe yizintambo ngezintambo ezincane ngokulandela imithetho, bese ziphenduka zibe yizintambo., lolu hlobo lokusonta lusetshenziswa kakhulu ukuhambisa umongo wekhebula le-rubber insulated ukuze kuthuthukiswe ukuguquguquka kwayo.Ziboshwe ngendlela engafanele (zihlanganiswe), zonke izintambo ezihlanganisiwe zisontekile ziqonde ohlangothini olufanayo.
2.1 Amakhondaktha ayindilinga angahlangene:
Ingxenye ephambanayo yomqhubi we-aluminium oyindilinga oyindilinga ngokuvamile ayikho ngaphansi kuka-10mm2.Izintambo ezilodwa ku-conductor kufanele zibe nobubanzi obufanayo, futhi inani lezintambo ezilodwa kanye nokumelana kwe-DC komqhubi kufanele kuhlangabezane nezindinganiso.
2.2 Amakhondaktha ayindilinga acindezelwe kanye namakhondaktha anomumo:
Ingxenye enqamulayo yamakhondaktha ayindilinga ayindilinga aqinile ayi-aluminium akumele ibe ngaphansi kuka-16mm2, ingxenye ephambanayo yamakhondaktha wethusi aboshwe noma i-aluminium akufanele ibe ngaphansi kuka-25mm2, isilinganiso sobubanzi bezintambo ezimbili ezihlukene ezihlukene ku-conductor efanayo akumele sidlule u-2. , kanye nenani lezintambo ezilodwa kanye nokumelana kwe-DC komqhubi kufanele kuhambisane nemithethonqubo evamile.
3. Ikhondatha ethambile:
Amakhondatha kufanele abe nocingo lwethusi olupuletiwe nolungafakwanga.Izintambo ezilodwa ku-conductor kufanele zibe nobubanzi obufanayo be-conductor, ububanzi bezintambo zocingo olulodwa ku-conductor akufanele budlule inani eliphakeme elishiwo, ububanzi bomqhubi wesithupha buncane kunalelo locingo olulodwa lwe-conductor wesihlanu, kanye ne-conductor. ukumelana akufanele kudlule inani eliphakeme elishiwo ezingeni.
