Hauv cov tshuab hluav taws xob niaj hnub, cov xaim yog cov muaj hluav taws xob tseem ceeb, ua kom muaj zog thiab txhim khu kev qha cov chaw sib kis. Thaum lub tsev xaim hluav taws xob yog qhov ncaj, txoj kev muaj kev lag luam muaj ntau ntxiv nyuaj. Lawv feem ntau koom nrogLub zog hnyav tam sim no, nce qhov chaw kub, raug rau noo noo, tshuaj lom neeg corrosion, kev ntxhov siab txhua yam, thiab kev mob sab nraum zoov.
Hauv cov ntsiab lus no, kev xaiv xaim xaim tsis yog tsuas yog muaj nuj nqis - nws yog qhov teeb meem ntawmKev Nyab Xeeb, Ua Raws Cai, thiab Ua Haujlwm Zoo.
Ib lo lus nug uas nquag los ntawm cov neeg yuav khoom thoob ntiaj teb:
"Nm {- b hlau phim rau kev lag luam siv?"
ThaumNm {- b hlau(Tsis - nws yog xim hlau sheathed cable, hom - b)Puas yog ib qho ntawm cov kev xaiv dav dav hauv North American cov chaw nyob thiab cov hluav taws xob coj mus muag, nws cov haum rau kev lag luam yuav tsum muaj kev soj ntsuam tob. Kab lus no yuav tshawb txog cov txheej txheem cov txheej txheem ntawm nm - b hlau, piv nws nrog lwm yam kev xaiv xws liThhn, UF - b, thiab xhhw, thiab muab cov lus qhia tseeb ntawm xaiv cov hlau zoo rau cov ntawv thov sib txawv.

Muaj Kev haum haum ntawm NM - b hlau
1. NEC CODE YUAV TSUM TAU
Raws liNational Electrical Code (NEC), Tshooj 334, Nm {- b raug txwv rau:
- Qhuav, sab hauv chaw.
- Zais xov hluav taws xob sab hauv phab ntsa thiab qab nthab.
- Thaj chaw tsis raug rau lub cev puas.
No tam sim ntawd cov cai tawm feem ntauCov Chaw Muaj Cov Vaj Tse, uas feem ntau koom nrog kev raug rau ya raws, roj, lossis kev ntxhov siab lub cev.
2. Kev lag luam ib puag ncig
Muaj kev muaj thaj chaw muaj cai yuav tsum tau tshaj plaws nm - b lub peev xwm:
- Cov Kub Kub Kuj: Cov ntaub ntawv, cov khoom ua haujlwm, lossis cov khw muag khoom siv ntau tshaj 90 degree.
- Ya raws tsis kam: Tshuaj nroj tsuag, cov chaw ua khoom noj, lossis cov tsev ua haujlwm feem ntau yuav tsum ntub dej {{0} {rated cables.
- NEEG KHO TSHUAB DURISHAB: Muaj cov plag tsev thiab cov kab ntau lawm thov kom cov kab uas tiv thaiv kev puas tsuaj thiab cuam tshuam.
- Yooj yooj: Cov khoom siv hluav taws xob feem ntau yuav tsum tau yoog raws tus cwj pwm, tsis yog cov neeg coj.
3. Tsawg txoj kev siv muaj kev siv
Uas tau hais tias, nm {- b kuj tseem siv tau nyob hauv cov xwm txheej tsawg:
- Hoobkas chaw ua haujlwm qhov chaw uas mob zoo ib yam li nyob thaj.
- Cia cov chaw ntim khoom nrog qhuav, qis - txoj kev pheej hmoo ib puag ncig.
- Tsawg -} power peruxiliary Tswj kev voj voog hauv qhuav cov ntaub ntawv.
👉 Lub ntsiab: Nm {- b tsuas tuaj yeem ua tau atheem nrab lub luag haujlwmHauv cov chaw muaj kev lag luam. Rau cov kev faib tawm tseem ceeb lossis cov xwm txheej hnyav, ntau hom hlau hlau yog qhov tseem ceeb.
Nm {- b vs lwm hom hlau
Txhawm rau kom nkag siab zoo dua uas nm {- b fits hauv cov toj roob hauv pes ntawm kev sib cav, ntawm no yog qhov sib piv nrog thhn, UF - b, thiab xhhw xov hlau:
