Raws li GB / T3956-1997, cov conductors tau muab faib ua plaub hom, thawj, thib ob, 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 hom thiab hom thib ob yog tsim los siv rau cov hlua khi ruaj ruaj, hom thib tsib thiab thib rau yog tsim rau cov cables hloov tau yooj yim thiab cov hlua, thiab thawj thiab thib ob hom yog npaj rau siv nyob rau hauv saj zawg zog cables thiab cords Rau yog softer tshaj lub thib tsib.
1. Khoom conductor:
Tus neeg xyuas pib cov ntaub ntawv yog metallized los yog unplated annealed tooj liab hlau, unplated aluminium los yog aluminium alloy hlau.
Cov khoom siv tooj liab yuav tsum yog ntawm cov voj voog, 25 thiab siab dua cov khoom siv tooj liab tsuas yog npaj rau cov cables tshwj xeeb, tsis yog rau cov cables dav dav; Cov khoom siv txhuas txhuas, ntu 16 thiab hauv qab no yuav tsum yog ntu ntu, 25 thiab siab dua, yog tias ib qho -core Lub cable yuav tsum yog hla hla- ntu, thiab nyob rau hauv rooj plaub ntawm ntau- core cables, tej zaum yuav yog ib ncig los yog zoo li tus ntoo khaub lig-section.
2. Stranded conductor:
Txhawm rau kom nce qhov yooj lossis kev ntaus nqi ntawm cov cable, tus loj dua {0}} ntu cable yog tsim los ntawm sib ntswg ntawm ntau cov xov hlau ntawm cov taub me me. Cov tub ntxhais hlau tso tseg 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 cov kab hauv nruab nrab ntawm cov tub ntxhais hlau tuaj yeem txav mus los sib npaug, thiab cov yas deformation ntawm tus neeg xyuas pib yuav tsis tshwm sim thaum khoov, yog li qhov softness ntawm cov tub ntxhais hlau qhov kev ua tau zoo. thiab stability tau zoo heev.
Daim ntawv twisting ntawm cov tub ntxhais hlau tuaj yeem muab faib ua ob pawg, tsis tu ncua twisting thiab tsis xwm yeem twisting. Lub ntsiab lus ntawm kev sib tw tsis tu ncua yog: qhov tsis tu ncua, concentric thiab cov khaubncaws sab nraud povtseg yog twisted nyob rau hauv cov lus qhia sib txawv, uas yog hu ua tsis tu ncua twisting. Nws kuj tseem tuaj yeem muab faib ua ib txwm twisting thiab txawv txav tsis tu ncua. Cov yav tas yog hais txog cov khaubncaws sab nraud povtseg thiab cov khaubncaws sab nraud povtseg Tsis tu ncua nrog cov diameters sib txawv ntawm cov xov hlau, thiab cov qub txhais tau tias cov diameters ntawm cov xov hlau yog tib yam; kev sib tw tsis tu ncua kuj tuaj yeem muab faib ua qhov yooj yim tsis tu ncua twisting thiab sib xyaw tsis tu ncua twisting, tom kawg txhais tau hais tias cov xov hlau uas ua kom tsis tu ncua twisting tsis yog. Nws yog ib tug hlau, tab sis ib tug nyias nyias yog twisted rau hauv strands raws li txoj cai, thiab ces twisted mus rau hauv ib tug core. Qhov 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 twisted (bundled twisted), tag nrho cov constituent xov hlau yog twisted nyob rau hauv tib txoj kev.
2.1 Tsis yog- compressed stranded round conductors:
Tus ntoo khaub lig ntawm cov stranded round aluminium conductor 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 tau raws li tus qauv yuav tsum tau ua.
2.2 Compression stranded round conductors thiab zoo li tus conductors:
Tus ntoo khaub lig ntawm lub compressed stranded round aluminium conductor yuav tsum tsis txhob tsawg tshaj li 16mm2, tus ntoo khaub lig seem ntawm stranded tooj liab los yog txhuas conductor yuav tsum tsis txhob tsawg tshaj li 25mm2, txoj kab uas hla ntawm ob txawv ib tug nyob ntawm tej nyob rau hauv tib neeg xyuas yuav tsum tsis txhob ntau tshaj 2. , tus naj npawb ntawm cov xov hlau ib leeg thiab DC tsis kam ntawm tus neeg xyuas pib yuav tsum tau ua raws li tus qauv yuav tsum tau ua.
3. Mos neeg xyuas pib (thib tsib thiab thib rau)
Tus neeg xyuas pib yuav tsum muaj cov xaim tooj liab annealed, ob qho tib si metallized thiab unmetallized. Ib cov xov hlau nyob rau hauv tus neeg xyuas pib yuav tsum muaj tib lub nominal txoj kab uas hla; tus tib txoj kab uas hla ntawm tus neeg xyuas pib yuav tsum tsis txhob tshaj tus nqi siab tshaj plaws, tus thib rau tus neeg xyuas pib yog nyias dua li tus neeg xyuas pib thib tsib ib txoj kab uas hla; tus neeg xyuas pib kuj yuav tsum tsis txhob tshaj tus nqi siab tshaj uas teev nyob rau hauv tus qauv.
