Hauv ntiaj teb ntawm kev teeb tsa hluav taws xob, cov lus "NEMA cable ladder" thiab "NEMA cable taisCov ntsiab lus no feem ntau raug hais txog. Cov tswv yim no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev tswj hwm cable zoo hauv ntau qhov chaw, los ntawm kev lag luam mus rau cov tsev lag luam. Tsab xov xwm no yuav tshawb nrhiav seb NEMA cable ladder yog dab tsi thiab qhia meej txog NEMA cable tray specification.
Dab tsi yog ib qhoNEMA Cable Ladder?
Ib lub ntaiv cable NEMA yog ib hom kev tswj cable uas siv los txhawb thiab teeb tsa cov cables. "NEMA" sawv cev rau National Electrical Manufacturers Manufacturers Association (NEMA), uas teeb tsa cov qauv rau cov khoom siv hluav taws xob thiab cov khoom hauv Tebchaws Meskas. Cov ntaiv cable NEMA feem ntau yog ua los ntawm cov ntaub ntawv xws li txhuas lossis hlau thiab tau tsim los muab lub moj khaum ruaj khov rau kev xa thiab kev ruaj ntseg cov cables.
Cov qauv ntaiv cable NEMA muaj cov ntaiv lossis cov kab hla uas tso cai rau cov cables kom tiaj tus, txo qhov kev ntxhov siab thiab kev puas tsuaj. Qhov kev tsim no zoo tshwj xeeb thaum cov cables xav tau khiav hla kev deb lossis hauv cov chaw uas muaj cov xov hlau ntau. Cov qauv qhib ntawm cov ntaiv cable kuj txhawb kev ncig cua, pab tshem tawm cov cua sov uas tsim los ntawm cov cables, yog li txhim kho kev nyab xeeb thiab kev ua tau zoo.
Qhov Tseem Ceeb ntawm NEMA Cov Qauv
Cov qauv NEMA ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom siv hluav taws xob, suav nrog cov ntaiv cable thiab cov tais, ua tau raws li cov qauv kev nyab xeeb thiab kev ua tau zoo tshwj xeeb. Cov qauv no tau tsim los ntawm kev pom zoo ntawm cov chaw tsim khoom, cov neeg siv, thiab lwm tus neeg koom nrog hauv kev lag luam hluav taws xob. Los ntawm kev ua raws li cov qauv NEMA, cov chaw tsim khoom tuaj yeem ua kom lawv cov khoom muaj kev ntseeg siab, muaj kev nyab xeeb, thiab sib xws nrog lwm cov khoom siv hluav taws xob.
Dab tsi yog qhovNEMA code rau cable tais?
Cov lus qhia ntawm NEMA rau cov tais cable tau teev tseg hauv tus qauv NEMA VE 2, uas muab cov lus qhia rau kev tsim qauv, kev tsim kho, thiab kev teeb tsa ntawm cov tais cable. Tus qauv no yog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov tais cable tuaj yeem txhawb nqa qhov hnyav ntawm cov cables thaum muab kev tiv thaiv txaus los ntawm cov yam ntxwv ib puag ncig xws li dej noo, hmoov av, thiab kev puas tsuaj rau lub cev.
Tus qauv NEMA VE 2 faib cov tais cable ua ntau hom, suav nrog cov tais ntaiv, cov tais hauv qab khov kho, thiab cov tais hauv qab. Txhua hom muaj cov ntawv thov thiab cov txiaj ntsig tshwj xeeb, nyob ntawm qhov chaw teeb tsa thiab hom cable siv. Piv txwv li, cov tais ntaiv yog qhov zoo tagnrho rau cov ntawv thov hnyav uas xav tau txhawb nqa ntau cov cables, thaum cov tais hauv qab khov kho zoo dua rau cov chaw uas muaj hmoov av thiab cov khib nyiab.
Thaum xaiv thiab teeb tsa NEMA cable ladders thiab trays, ntau yam yuav tsum tau xav txog:
1. **Qhov Hnyav Peev Xwm**: Xyuas kom tseeb tias lub ntaiv cable lossis lub tais cable tuaj yeem txhawb qhov hnyav ntawm cov cables uas tau teeb tsa. Qhov no suav nrog kev xav txog qhov hnyav ntawm cov cables nws tus kheej nrog rau lwm yam xws li tej yam ib puag ncig.
2. **Kev Xaiv Khoom Siv**: Xaiv cov khoom siv uas tsim nyog rau qhov chaw uas nws yuav raug teeb tsa. Piv txwv li, nyob rau hauv ib puag ncig corrosive, txhuas yuav yog cov khoom siv nyiam; thaum hlau yuav tsim nyog dua rau cov ntawv thov hnyav.
3. **NEMA Ua Raws Li**: Ib txwm siv tus qauv NEMA VE 2 kom ntseeg tau tias lub cable tray system ua tau raws li txhua yam kev nyab xeeb thiab kev ua haujlwm uas tsim nyog.
4. **Kev Xyaum Txhim Kho**: Ua raws li cov kev xyaum txhim kho zoo tshaj plaws kom ntseeg tau tias cov ntaiv cable lossis cov tais cable tau teeb tsa kom ruaj khov thiab cov cables tau raug xa thiab ruaj ntseg zoo.
NEMA cable laddersthiab NEMA cov lus qhia cable tray yog qhov tseem ceeb rau kev tswj hwm cable zoo hauv kev teeb tsa hluav taws xob. Los ntawm kev nkag siab txog cov lus qhia thiab cov qauv uas NEMA teeb tsa, cov kws tshaj lij tuaj yeem ua kom lawv cov kev teeb tsa muaj kev nyab xeeb, ua haujlwm tau zoo, thiab ua raws li cov cai ntawm kev lag luam. Txawm hais tias nyob rau hauv kev lag luam, kev lag luam, lossis chaw nyob, kev siv NEMA cable ladders thiab trays kom raug tuaj yeem ua rau muaj kev ntseeg siab thiab lub neej ntev ntawm cov kab ke hluav taws xob.
