Muaj ob hom cables, ib leeg-core cables thiab multi-core cables.
Vim hais tias cable yog nrov tshaj plaws (thiab feem ntau tsuas yog) txoj hauv kev kom muaj zog rau qhov chaw.
Yog li, lawv nyob txhua qhov chaw. Koj tuaj yeem pom lawv hauv tsev, lub pov haum, pej xeem vaj tse, txoj kev thiab khw khw.
Ib qho tseem ceeb hauv av cable yuav tsis pom vim nws tau faus rau hauv ib lub trench, thaum daim ntawv thov ntau-core cable tuaj yeem pom rau txhua tus, khiav ntawm phab ntsa lossis qab nthab.
Qhov no tsa cov lus nug: dab tsi yog ib tug tub ntxhais cable los yog ib tug multi-core cable?
Vim li cas koj thiaj xaiv siv ntau cov tub ntxhais cables es tsis txhob siv cov tub ntxhais ib leeg?
Hauv tsab xov xwm tom ntej no, peb yuav tham txog cov lus nug no thiab muab cov lus teb rau koj.
Tom qab nyeem cov ntaub ntawv muab, koj yuav muaj peev xwm sib txuas lus nrog cov tub ceev xwm, ib tus tub ntxhais lossis cov tub ntxhais sib txuas ntau cov khoom siv thaum sib tham txog kev yuav khoom cable rau txoj haujlwm txuas ntxiv tom ntej.
Dab tsi yog Ib Tug Tub Ntxhais Cable?
Lo lus teb rau lo lus nug no yog nyob rau hauv nqe lus nug nws tus kheej. Lub sij hawm “ib core” yog siv los piav cable nrog ib tug neeg xyuas pib.
Cov no txawv ntawm lwm hom cables, uas yog tsim los ua multi-core cable hom.
Cov neeg ua haujlwm nyob rau hauv ib qho tseem ceeb cables tuaj yeem ua los ntawm tooj liab lossis aluminium insulating cov ntaub ntawv.
Contrary to li cas ib txhia yuav xav, ib leeg tub ntxhais cable tsis tas yuav hloov tau yooj yim dua los yog tsis yooj yim dua li cov tub ntxhais cable ntau, los yog thicker los yog nyias.
Cov yam ntxwv no (tuab, nyias, yooj, los yog tawv) feem ntau yog nyob ntawm qhov loj ntawm ib leeg tub ntxhais cable siv rau ib daim ntawv thov tshwj xeeb.
Qhov loj thiab tuab nyob ntawm qhov loj ntawm cov kab. Cov kab kab loj loj tsis hloov pauv ntau dua li cov kab me me.
Dab tsi yog Tib Core Cable Siv rau?
Ib leeg tub ntxhais cable yog tej zaum ib qho ntawm cov xov hlau uas siv ntau tshaj plaws hauv peb lub tsev, khw, kev lag luam thiab chaw ua lag luam.
Feem ntau nquag siv ntawm ib leeg stranded cables yog xa hluav taws xob los ntawm ib qho chaw mus rau lwm qhov.
Txawm yog, nyob ntawm qhov xav tau ib qho tseem ceeb cable loj, nws daim ntawv thov kuj tseem yuav txuas ntxiv mus rau lwm qhov chaw, xws li xaim hauv cov khoom siv hluav taws xob thiab khoom siv.
Koj tuaj yeem pom ib qho tseem ceeb, tsis muaj sheathed cables rau kev siv hluav taws xob, suav nrog cov khoom siv hluav taws xob rau computers, fais fab tswj vaj huam sib luag, thiab cov khoom siv hluav taws xob.
Rau cov ntawv thov uas muaj kev pheej hmoo ntawm electromagnetic cuam tshuam (EMI), koj tseem tuaj yeem tau txais ib qho tseem ceeb ntawm cov xaim nrog cov ntaub thaiv tshwj xeeb uas tsim los rau hauv lub cable.
Ib qho kev teeb tsa zoo sib xws kuj tseem tuaj yeem siv rau kev hloov pauv ntau lub cables. Qhov no shielded cable tseem hu ua braided cable.
Kev puas tsuaj rau nws cov haujlwm, xws li cov teeb liab los ntawm cov khoom siv sib txuas lus lossis cov khoom siv hluav taws xob hluav taws xob los ntawm cov khoom siv hluav taws xob siab lossis cov khoom siv hluav taws xob.
Piv txwv, yog tias lub cable hla ze lub qhov cub microwave lossis khoom siv hauv tsev, tus kws tshaj lij hluav taws xob tuaj yeem siv ib qho tseem ceeb braided cable los tiv thaiv cable.
Zoo sib xws, yog tias daim ntawv thov kev txuas hla ze ntawm lub tshuab hluav taws xob, yeej ib txwm muaj kev pheej hmoo tias EMI los ntawm lub tshuab hluav taws xob tuaj yeem cuam tshuam rau kev ncaj ncees ntawm cable.
Hauv qhov no, multi-core lossis ib leeg tub ntxhais braided cables tuaj yeem siv tau.
Weaving los yog shielding muaj lwm yam siv.
Qee zaum, engineers yuav siv braided los yog shielded ib core saj zawg zog cables nyob rau hauv daim ntawv thov uas yuav tsum tau me ntsis zog cables.
Interwoven hlau braids muaj ob txoj kev siv.
Thawj, nws pab txo EMI, uas yuav ua rau muaj kev phom sij rau kev siv cable.
Txawm yog, kev siv ib leeg tub ntxhais braided cables txhim khu lub zog tag nrho cable piv rau hom unshielded.
Nws tiv thaiv cov cable los ntawm cov neeg kho tshuab kev nyuaj siab thiab ncua nws lub neej kev pab cuam.
Kawg no, ib tug tub ntxhais xov hlau nrog braids kuj siv nyob rau hauv daim ntaub ntawv uas engineers xav tau cables los qhia ntxiv saj zawg zog.
Vim hais tias lub braid yog tsim raws li ib tug interlaced lattice raj, ib tug tub ntxhais braided cable los yog zoo li multi-core cable, nws txhim khu cov insulating neeg xyuas pib hauv qab no thiab ntxiv yooj thiab versatility rau tag nrho cov cable.
Piv txwv, Txoj kev no yog siv rau hauv cov ntawv thov txuas qhov twg ib qho xaim cable yuav ntsib qhov nro thiab distortion thaum lub sijhawm teeb tsa.
Tib lub tswv yim siv tau thaum xav tau ntau cov tub ntxhais cables hloov tau.
Qhov zoo thiab qhov tsis zoo ntawm ib leeg tub ntxhais Cable?
Raws li ib txwm, qhov xwm thiab hom ntawm daim ntawv thov txiav txim seb hom kev xaiv routing.
Piv txwv, nyob ntawm koj lub hom phiaj project, Koj tuaj yeem txiav txim siab seb puas yuav siv 6mm ib leeg tub ntxhais cable.
Tab sis rau lwm daim ntawv thov, qhov no yuav tsis yog qhov tsim nyog tshaj plaws.
Txhua hom cable muaj nws qhov zoo, enabling engineers thiab electricians xaiv tej cables rau lawv tej yaam num.
Yog tias 0.75mm ib leeg tub ntxhais cable yog qhov kev xaiv zoo rau kev siv sab hauv tsev, nws yuav tsis yog qhov kev xaiv zoo tshaj plaws rau kev siv sab nraum zoov.
Txawm yog, siv ib hom cable hla lwm hom cable muaj qhov zoo thiab qhov tsis zoo.
Qhov zoo ntawm Single Core Cable:
- Yooj yim rau nruab ntawm theem
- Qhov ua tau ntawm luv luv Circuit Court ntawm ntau theem yog me me
- Yooj yim rau kev thauj mus los ntev (Piv txwv, ib yob ntawm 10mm ib leeg tub ntxhais cable yog yooj yim dua (thiab siv qhov chaw tsawg dua) tshaj qhov sib npaug multi-core cable hom)
- Yooj yim los npaj thiab nruab
- Cov kab hluav taws xob ntev tuaj yeem siv nrog tib lub peev xwm sib txuas raws li cov tub ntxhais cables
Disadvantages ntawm Single Core Cable:
Cov cables no tsis tuaj yeem ua armored thiab yog li tsis haum rau cov ntawv thov uas muaj kev pheej hmoo ntawm kev ntxhov siab.
Vim tsis muaj armor, ib leeg tub ntxhais cables muaj kev cuam tshuam rau sab nraud quab yuam.
Armored cables yog qhov nyiam rau cov ntawv thov uas xav tau kev teeb tsa ntawm cov cables nyob rau hauv cov xwm txheej hnyav.
Piv txwv, txij li 2.5mm ib leeg tub ntxhais cables tsis tuaj yeem ua armored nrog hlau nplaum hlau los yog hlau nplaum.
Nws yog qhov nyuaj dua rau nruab ntau cov tub ntxhais cables ntawm tib qhov loj me hauv qhov chaw muaj kev ntxhov siab thiab muaj kev ntxhov siab..
Ib leeg tub ntxhais cables tsuas yog muaj kev tiv thaiv los ntawm ib txheej txheej, uas ua rau lawv yooj yim dua rau kev puas tsuaj.
Kev puas tsuaj me ntsis rau lub tsev yuav ua rau luv luv.
Hauv kev siv siab siv, ib leeg tub ntxhais cables yuav tsum tau grounded ntawm ntau lub ntsiab lus, uas yuav ua rau muaj kev pheej hmoo ntawm kev ncig.
Qhov twg yuav ib leeg tub ntxhais Cables?
Raws li qhov tshwm sim, cables feem ntau yuav overheat thiab nws thiaj li hlawv tawm, qhov twg kuv tuaj yeem yuav high-quality ib leeg tub ntxhais cables?
Tam sim no koj paub txog qhov sib txawv ntawm ib leeg tub ntxhais cable thiab multi-core cable
Kuj, koj twb paub qhov zoo thiab qhov tsis zoo ntawm kev xaiv ib lub cable.
Koj tuaj yeem ua qhov kev txiav txim siab zoo dua ntawm kev yuav khoom cable.
Kawm paub ntxiv txog leej twg yog tus tsim khoom.
Ntawm ZMS cable, peb muab ntau yam ib leeg tub ntxhais cables rau ntau yam kev siv.
Peb kuj yog cov chaw tsim khoom lag luam thiab cov khoom siv hluav taws xob multi-core.
Peb cov khoom dhau los ntawm cov txheej txheem tswj xyuas kom zoo thiab raug kuaj raws li cov qauv thoob ntiaj teb siab tshaj plaws.
