Stranded Electric Cable yog ntau yam thiab tseem ceeb ntawm cov khoom siv hluav taws xob siv nyob rau hauv ntau yam kev lag luam thiab kev siv. Tsis zoo li cov hlau tsis muaj zog, uas muaj ib tug hlau conductor, stranded cable yog tsim los ntawm bundling ntau me me strands ntawm hlau rau hauv ib qho, tus neeg xyuas pib loj dua. Qhov kev tsim no muab tso tseg cable tshwj xeeb uas ua rau nws hloov tau yooj yim dua, ruaj, thiab tsim nyog rau kev siv tshwj xeeb uas cov hlau tsis yog qhov kev xaiv zoo tshaj plaws.
Hauv tsab xov xwm no, peb yuav dhia tob rau hauv qhov xwm txheej ntawm txoj hlua khi, nws cov txiaj ntsig thiab qhov tsis zoo, ntau hom muaj, thiab tshawb nrhiav cov ntawv thov sib txawv thoob plaws cov haujlwm sib txawv. Thaum kawg, koj yuav nkag siab tias vim li cas cov hlua khi hlua khi yog ib qho kev daws teeb meem hauv kev lag luam xws li kev tsim kho mus rau kev sib txuas lus.
1. Dab tsi yog Stranded Cable?
Stranded kab, qee zaum hu ua stranded hlau, muaj ntau cov xov hlau me me twisted los yog braided ua ke los tsim ib tus neeg xyuas pib loj dua. Txoj kev tsim kho no contrasts nrog Khoom Hlau, uas nta tsuas yog ib qho khoom siv hlau. Stranded cables feem ntau yog ua los ntawm tooj liab los yog aluminium, thiab lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg, ntev, thiab configurations kom tau raws li cov kev xav tau tshwj xeeb.
Cov hlau uas siv ntau tshaj plaws hauv cov hlua khi yog:
- Tooj liab: Paub txog nws high conductivity thiab yooj.
- Aluminium: Lub teeb thiab pheej yig, feem ntau siv hauv cov tshuab hluav taws xob faib hluav taws xob.
- Tinned Copper: Copper strands coated nrog tin los tiv thaiv corrosion, pab tau nyob rau hauv ib puag ncig moist los yog corrosive.
Stranded cables kuj tseem muaj cov rwb thaiv tsev sib txawv, xws li PVC (polyvinyl chloride), roj hmab, los yog silicone, nyob ntawm cov kev cai tshwj xeeb rau hluav taws xob rwb thaiv tsev, yam ruaj khov, thiab kev tiv thaiv ib puag ncig.
2. Yuav Ua Li Cas Stranded Hluav Taws Xob Cables Ua
Kev tsim cov hlua khi hlua khi muaj cov txheej txheem hu ua txoj hlua khi. Qhov no suav nrog kev sib tw ntau cov hlua ntawm cov xaim nyob ib ncig ntawm ib leeg los tsim ib qho ntxiv saj zawg zog thiab robust cable. Cov hlua khi hlua khi tuaj yeem teem caij sib txawv, xws li:
- Concentric stranding: Qhov twg cov khaubncaws sab nraud povtseg yog twisted nyob rau hauv concentric voj voog nyob ib ncig ntawm ib tug central hlau.
- Bunched stranding: Hauv hom no, strands tsuas yog twisted ua ke nrog tsis muaj kev npaj tshwj xeeb.
- Txoj hlua-lay stranding: Txoj kev no muaj cov pab pawg me me ntawm cov xov hlau sib tw sib tw ua ke los tsim cov kab tuab dua.
Txhua hom kev stranding cuam tshuam rau cable kev ua tau zoo nyob rau hauv ntau txoj kev, xws li nws yooj, zog, thiab muaj peev xwm nqa tau tam sim no.
3. Cov txiaj ntsig ntawm Stranded Cable
