Nkag siab Peb Cov Hluav Taws Xob Hluav Taws Xob: CM, CMR, thiab CMP

Thaum nws los txog rau kev tsim cov tshuab hluav taws xob muaj kev nyab xeeb thiab txhim khu kev qha, kev nkag siab txog qhov ntsuas hluav taws xob yog qhov tseem ceeb. National Electrical Code (NEC) muab cov lus qhia rau kev faib cov cables raws li lawv cov khoom tiv thaiv hluav taws. Ntawm cov kab hluav taws xob siv hluav taws xob feem ntau yog CM, CMR, thiab CMP. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov yam ntxwv thiab kev siv ntawm txhua hom los pab koj txiav txim siab paub txog koj qhov kev teeb tsa hluav taws xob.

CM cables, tseem hu ua Communication Multiplepurpose cables, yog tsim los siv nyob rau hauv ntsug daim ntaub ntawv nyob rau hauv ib lub tsev. Cov cables no feem ntau yog siv rau kev sib txuas lus cov ntaub ntawv, xws li Ethernet lossis kev sib txuas lus. Thaum CM cables muab ib theem ntawm kev tiv thaiv hluav taws, lawv tsis haum rau kev teeb tsa uas yuav tsum tau txhim kho cov nplaim hluav taws.CM cables feem ntau yog siv rau hauv cov cheeb tsam uas tsis yog plenum, xws li chaw ua haujlwm, tsev nyob, thiab chaw ua lag luam.

Cov yam ntxwv tseem ceeb thiab kev siv:

• Kev tiv thaiv hluav taws kub nruab nrab: CM cables yog tsim los txwv kev sib kis ntawm hluav taws rau qee qhov, muab qee qhov kev nyab xeeb.

• Tsim nyog rau kev teeb tsa ntsug: CM cables yog tsim los siv rau hauv kev siv ntsug riser, xws li hauv pem teb lossis hauv cov ncej. Cov kev siv ntau: Cov cables no feem ntau siv rau cov ntaub ntawv sib txuas lus, suav nrog kev sib tham, xov tooj, thiab kev soj ntsuam video.

CMR cables, tseem hu ua Kev Sib Txuas Lus Multiplepurpose Riser cables, muab kev tiv thaiv hluav taws zoo dua piv rau CM cables. Lawv tau tsim los rau kev teeb tsa ntsug hauv cov tsev, muab kev nyab xeeb thiab kev ntseeg tau. CMR cables tau siv dav hauv kev lag luam thiab chaw nyob qhov twg yuav tsum muaj kev tiv thaiv hluav taws ntxiv.

Cov yam ntxwv tseem ceeb thiab kev siv:

• Txhim khu kev tiv thaiv hluav taws: CMR cables yog tsim los tiv thaiv hluav taws thiab txwv tsis pub nws kis tau, muab kev nyab xeeb ntxiv thaum muaj hluav taws kub. Vertical installations: Zoo ib yam li CM cables, CMR cables yog tsim rau ntsug riser daim ntaub ntawv.

• Kev siv dav: CMR cables feem ntau siv hauv cov tsev lag luam, tsev kawm ntawv, tsev kho mob, thiab thaj chaw nyob uas yuav tsum muaj kev tiv thaiv hluav taws kom siab.

CMP cables, tseem hu ua Kev Sib Txuas Lus Plenum cables, yog tsim los siv rau hauv plenum qhov chaw. Plenum qhov chaw yog thaj chaw nyob hauv ib lub tsev cov qauv uas huab cua circulates, xws li qhov chaw saum toj no suspended ceilings los yog nyob rau hauv pem teb tsa. Cov chaw no xav tau cov kab hluav taws xob uas muaj qib siab tshaj plaws ntawm kev tiv thaiv hluav taws kom txo tau qhov kev pheej hmoo ntawm hluav taws.

Cov yam ntxwv tseem ceeb thiab kev siv:

• Kev tiv thaiv hluav taws kub siab tshaj plaws: CMP cables muab qib siab tshaj plaws ntawm hluav taws kub ntawm peb hom. Lawv tau tsim los ntawm cov khoom siv los tiv thaiv kev sib kis ntawm cov nplaim taws thiab tso pa tawm ntawm cov pa taws thiab cov pa phem.

• Plenum qhov chaw teeb tsa: CMP cables tshwj xeeb yog tsim los rau kev teeb tsa hauv plenum thaj chaw uas muaj kev nyab xeeb hluav taws tseem ceeb heev. Cov kev siv ntau: Cov cables no feem ntau siv hauv cov tsev lag luam, cov tsev kawm ntawv, cov chaw kho mob, thiab lwm qhov chaw uas muaj qhov chaw plenum.

Kev nkag siab txog qhov sib txawv ntawm cov hluav taws xob hluav taws xob uas tau teev tseg los ntawm NEC yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob. CM, CMR, thiab CMP cables txhua tus ua haujlwm tshwj xeeb raws li lawv cov yam ntxwv tiv thaiv hluav taws. Txawm hais tias koj xav tau kev tiv thaiv hluav taws kub nruab nrab rau kev xav tau kev sib txuas lus dav dav (CM), kev tiv thaiv hluav taws ntau ntxiv rau kev teeb tsa ntsug (CMR), lossis qib siab tshaj plaws ntawm kev nyab xeeb hluav taws rau plenum qhov chaw (CMP), xaiv hom cable tsim nyog yog qhov tseem ceeb. Los ntawm kev ua raws li NEC cov lus qhia thiab xaiv txoj cai hluav taws xob ntsuas hluav taws xob, koj tuaj yeem tsim cov tshuab hluav taws xob uas tseem ceeb rau kev nyab xeeb thiab ua raws.
