Raws li IEC60228, cable conductors tau muab faib ua plaub hom, thawj hom, thib ob, hom thib tsib, thiab thib rau.Thawj hom yog cov khoom siv hluav taws xob, hom thib ob yog tus neeg xyuas pib tso tseg, thawj thiab thib ob hom yog tsim los siv rau cov hlua khi ruaj ruaj, hom thib tsib thiab thib rau yog tsim los siv rau cov cables hloov tau yooj yim thiab cov hlua, thiab qhov thib ob. hom yog npaj rau conductors ntawm saj zawg zog cables thiab cords.Rau yog softer dua thib tsib.
1. Khoom conductor:
Metallized los yog unplated annealed tooj liab hlau, uncoated aluminium los yog aluminium alloy hlau rau cov ntaub ntawv neeg xyuas pib.
Cov khoom siv tooj liab yuav tsum yog lub voj voog hla ntu, 25mm2 thiab siab dua cov khoom siv tooj liab tsuas yog npaj rau cov cables tshwj xeeb, tsis yog rau cov cables dav dav;Rau cov khoom siv hluav taws xob txhuas, ntu 16mm2 thiab hauv qab no yuav tsum yog ncig, rau 25mm2 thiab siab dua, nws yuav tsum yog nyob rau hauv cov ntaub ntawv ntawm ib leeg-core cables, thiab tej zaum yuav ncig los yog zoo li tus nyob rau hauv cov ntaub ntawv ntawm multi-core cables.
2. Stranded conductor:
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau), nws raug nquahu kom siv txoj hlua khi, cov hlua txuas nrog qhov loj dua qhov sib tshooj yog tsim los ntawm kev sib tw ntau cov xov hlau uas muaj txoj kab uas hla me me.Cov tub ntxhais hlau twisted los ntawm ntau cov xov hlau ib leeg muaj qhov yooj yooj yim thiab loj curvature.Thaum cov tub ntxhais hlau yog khoov, sab hauv thiab sab nraud ntawm txoj kab nruab nrab ntawm cov tub ntxhais hlau tuaj yeem txav mus thiab them nyiaj rau ib leeg.Thaum khoov, nws yuav tsis ua rau cov yas deformation ntawm tus neeg xyuas pib, yog li cov tub ntxhais hlau yog mos.Kev ua tau zoo thiab kev ruaj ntseg zoo heev.
Daim ntawv stranding ntawm cov tub ntxhais yuav muab faib ua ob hom, tsis tu ncua stranding thiab irregular stranding.Lub ntsiab lus ntawm kev stranding tsis tu ncua yog: cov stranding ntawm conductors nrog tsis tu ncua, concentricity thiab successive khaubncaws sab nraud povtseg nyob rau hauv txawv kev qhia yog hu ua tsis tu ncua stranding.Nws tseem tuaj yeem muab faib ua ib txwm stranding thiab txawv txav tsis tu ncua stranding.Lub tom kawg yog hais txog txheej-rau-txheej Cov txheej txheem tsis tu ncua nrog cov kab sib txawv ntawm cov xaim sib txawv, thaum lub qub txhais tau hais tias cov diameters ntawm cov khoom siv hlau yog tib yam;Tsis tu ncua stranding tseem tuaj yeem muab faib ua qhov yooj yim tsis tu ncua stranding thiab compound tsis tu ncua stranding.Cov tom kawg txhais tau hais tias cov xov hlau uas tsim cov stranding tsis tu ncua tsis yog ib leeg, tab sis yog twisted rau hauv strands los ntawm cov xov hlau nyias nyias raws li txoj cai, thiab tom qab ntawd twisted rau hauv cores., hom kev sib tw no feem ntau yog siv los txav cov tub ntxhais ntawm cov roj hmab insulated cable los txhim kho nws qhov yooj.Irregularly stranded (bundled), tag nrho cov constituent xov hlau yog twisted nyob rau hauv tib txoj kev.
2.1 Non-compact stranded round conductors:
Tus ntoo khaub lig ntawm stranded round aluminium conductor yog feem ntau tsis tsawg tshaj li 10mm2.Ib cov xov hlau nyob hauv tus neeg xyuas pib yuav tsum muaj tib lub nominal txoj kab uas hla, thiab cov xov tooj ntawm ib leeg thiab DC tsis kam ntawm tus neeg xyuas pib yuav tsum ua raws li cov qauv.
2.2 Compression stranded round conductors thiab zoo li tus neeg xyuas pib:
Txoj kab uas hla ntawm txoj kab uas hla nruj nreem kaw yuav tsum tsis pub tsawg tshaj 16 hli 2, qhov hla ntu ntawm cov hlua khi tooj liab lossis txhuas tus neeg xyuas yuav tsum tsis pub tsawg dua 25mm2, txoj kab uas hla ntawm ob txoj kab sib txawv ntawm tib tus neeg xyuas pib yuav tsum tsis pub tshaj 2. , thiab tus naj npawb ntawm cov xov hlau ib leeg thiab DC tsis kam ntawm tus neeg xyuas pib yuav tsum ua raws li cov txheej txheem kev cai.
3. Mos conductor:
Tus neeg xyuas pib yuav tsum muaj cov plated thiab unplated annealed tooj liab hlau.Ib cov xov hlau nyob hauv tus neeg xyuas pib yuav tsum muaj tib lub nominal txoj kab uas hla, txoj kab uas hla ntawm ib lub xov hlau nyob hauv tus neeg xyuas pib yuav tsum tsis pub tshaj tus nqi siab tshaj plaws, txoj kab uas hla ntawm tus neeg xyuas pib thib rau yog nyias dua li ntawm tsib tus neeg xyuas pib ib lub xaim, thiab tus neeg xyuas pib. kuj yuav tsum tsis txhob tshaj tus nqi siab tshaj uas teev nyob rau hauv tus qauv.
