Hauv lub zej zog niaj hnub, cables khaws peb cov khoom sib txuas, thiab cov cables yog qhov tseem ceeb hauv peb lub neej niaj hnub. Cov lus qhia no yuav coj koj los ntawm cov kauj ruam tseem ceeb los xyuas kom koj txiav txim siab zoo thaum xaiv tau thiab yuav siv cable thawj zaug? Cables muaj ntau txoj kev siv, los ntawm kev hloov cov ntaub ntawv thiab audio / video teeb tsa kom xa hluav taws xob. Tom ntej no, xav txog txoj kev teeb tsa ib puag ncig ntawm cable. Nws puas yuav siv sab hauv tsev lossis sab nraum zoov? Sab nraum zoov cables yuav tsum muaj peev xwm tiv taus huab cua hnyav. Lawv yuav tsum muaj lub ntsej muag ruaj khov, xws li polyethylene (PE) lossis polyvinyl chloride (PVC) nrog UV kev tiv thaiv. Nyob sab hauv tsev, txawm hais tias tsis tas yuav muaj huab cua tsis kam, tej zaum yuav xav ua raws li cov qauv kev nyab xeeb, tshwj xeeb hauv cov tsev lag luam.
Qhov ntev ntawm lub cable yog lwm qhov tseem ceeb. Ntsuas qhov kev ncua deb ntawm ob lub ntsiab lus uas lub cable txuas, thiab tom qab ntawd ntxiv me ntsis ntev ntev rau tus nqi, sib ntswg, lossis kev hloov kho yav tom ntej, lossis kev hloov kho yav tom ntej.
Nkag siab txog cov kev qhia tseem ceeb rau koj ib zaug koj tau qhia meej txog koj cov kev xav tau tom ntej yog kom paub koj tus kheej cov kev paub tseem ceeb uas txiav txim siab ntawm kev ua haujlwm ntawm cable.
Kev ua kom tsis pom zoo tseem yog qhov tseem ceeb los xav txog. Attenuation hais txog qhov poob ntawm lub teeb liab lub zog thaum nws mus ncig dhau ntawm cable. Ntev lub cable thiab ntau dua lub teeb liab zaus, qhov hnyav dua rau kev ua kom loj. Txhawm rau txo cov kab mob, xaiv cables nrog high- zoo saib, xws li tooj liab {} claw aluminium (CCA) lossis tooj liab. Ntshiab tooj liab tooj liab uas tau zoo dua thiab qis dua kev xaiv, ua rau lawv xaiv tau zoo dua rau qhov ntev} deb} {{7} {{7} {{7} {{7} {{7} {{7} {{7} {{}} kev thov ua tiav.
Kev thaiv npog tseem yog tus yam ntxwv tseem ceeb ntawm cov ceg siv hauv cov chaw nrov nrov. Electromagict cuam tshuam (EMI) thiab xov tooj cua tsis sib cuam tshuam Shielded cables, xws li stp (shielded twisted khub) lossis SF / UTP (ntawv ci (ntawv ci (ntawv ci (ntawv ci (ntawv ci (ntawv ci)
Xaiv cov khoom siv cable tsim nyog yog qhov tseem ceeb rau cov neeg ua yeeb yam cable thiab txheej txheem rwb thaiv tsev. Cov ntaub ntawv siv rau tus neeg saib xyuas thiab cov txheej txheem rwb thaiv tsev ua si lub luag haujlwm tseem ceeb hauv lawv qhov kev ua tau zoo, ruaj khov, thiab tus nqi. Tooj liab yog cov khoom siv uas siv tau ntau rau cov neeg sib txuas lus vim tias nws ua tau zoo heev. Ntshiab tooj liab cov neeg saib xyuas yog tsim nyog rau siab- kev siv cov ntawv thov, tab sis lawv kuj kim dua. CCA CLENSORS (CEAKE CORE NROG COPPER Txheej) yog kev xaiv luam tawm ntau dua, tab sis lawv muaj ntau dua resistivity.
Los ntawm cov khoom siv txhim khu kev qha
Muaj ntau tus neeg muag khoom hauv kev ua lag luam, thiab nws tuaj yeem nyuaj rau kev txheeb xyuas uas yog trustworthy. Thawj kauj ruam tuaj yeem tshawb nrhiav cov chaw muag khoom online thiab nyeem cov neeg siv khoom tshuaj xyuas kom pib kev tshawb fawb. Nrhiav rau cov neeg xa khoom uas paub txog kev muab siab- cov khoom lag luam zoo thiab cov kev pabcuam zoo rau cov neeg siv khoom. Ib qho ntxiv, cov lus nug thiab lub sijhawm khoom xa tuaj ntawm cov neeg xa khoom yuav tsum tau txiav txim siab. Yog tias koj muaj cov phiaj xwm npaj nruj, koj xav tau ib tus neeg xa khoom uas tuaj yeem xa cov roj hmab sai sai. Nug txog lawv cov lus nug cov lus nug thiab kev thauj mus los kom ntseeg tau tias lawv tuaj yeem ua tau raws li koj cov kev xav tau.
Tau kawg, tus nqi yog ib qho kev xav tau, tab sis nws yuav tsum tsis yog tib qho kev sib. Qhov pheej yig dua cov kab ke yuav muaj qis dua, uas tuaj yeem ua rau cov teeb meem kev ua tau zoo thiab cov nqi kho kim kim.
Nram qab no kev lag luam thiab kev tsim kho tshiab
Kev lag luam cable yog hloov zuj zus, nrog cov thev naus laus zis tshiab thiab kev tsim kho tshiab tshwm sim tas li. Nkag siab cov qauv no tuaj yeem pab koj txiav txim siab tau zoo dua thaum kev xaiv thiab kev yuav khoom rau koj cov haujlwm.
Txawm hais tias muaj kev xav zoo tshaj plaws, nws yog qhov yooj yim kom ua yuam kev thaum xaiv thiab kev yuav khoom cables. Ib qho kev ua txhaum no xaiv hom tsis raug ntawm cable rau daim ntawv thov.
Underestimating ntev ntawm cov cables kuj yog ib qho yuam kev. Raws li tau hais ua ntej, nws yog ib qho tseem ceeb kom muaj kev ntsuas kom raug qhov deb thiab tshwj tseg ntev ntev rau khoov thiab hloov kho. Siv cov kab ke luv luv yuav xav tau cov hlua txuas ntxiv, uas yuav txo cov teeb liab zoo. Ntawm qhov tod tes, overestimating ntev yuav nkim nyiaj thiab ua rau tsis tsim nyog.
Tsis kuaj qhov zoo ntawm cov cables kuj yog qhov yuam kev. Tsawg {- Cov qoob loo zoo, cov hluav taws xob tsis txaus, uas tsis muaj kev phom sij, uas tuaj yeem ua rau cov teeb meem kev nyab xeeb thiab kev nyab xeeb. Ua ntej kev yuav khoom, nco ntsoov xyuas cov cables thiab saib rau cov cim ntawm kev ua tau zoo, thiab lub qhov txhab nruj me ntsis sib dhos, thiab cov xwm txheej ruaj khov.
Thaum kawg, sib koom tes nrog cov chaw tsis muaj peev xwm ua rau cov teeb meem xws li kev xa khoom, xaj yuam kev, lossis qis {{{}} Cov khoom zoo. Kev siv sijhawm tshawb nrhiav cov neeg xa khoom thiab xaiv cov uas muaj lub koob npe zoo thiab leej twg tuaj yeem muab kev txhawb nqa uas koj xav tau. Hauv cov ntsiab lus xaus, kom tau cov kab ke uas tsim nyog, koj yuav tsum xav txog koj cov kev xav tau, xaiv cov khoom siv tau, yuav los ntawm kev txhim kho cov neeg muag khoom, thiab txuas ntxiv ntsuas kev lag luam. Los ntawm ua raws cov kauj ruam no thiab zam kev tsis ua yuam kev, koj tuaj yeem xyuas kom meej tias koj xaiv cov qoob loo uas ua tau raws li koj cov kev xav tau.
