Thaum nws los txog rau cov chaw nyob thiab cov lag luam kev lag luam hluav taws xob hauv Tebchaws Meskas thiab Canada, ib lub npe sawv saum tus so -Nm {- b cableCov. Paub txog nws cov versatility, ua raws li cov qauv UL, thiab yooj yim} b cable tau ua cov hluav taws xob thiab cov lag luam. Txawm li cas los xij, ntau tus neeg yuav khoom tseem nug:Dab tsi tiag yog nm {{- b cable, dab tsi ua rau nws txawv ntawm lwm cov cable, thiab nws yuav tsum raug xaiv rau cov ntawv thov tshwj xeeb li cas?
Hauv tsab xov xwm no, peb yuav muab ibKev qhia dav dav rau nm - b cable, suav nrog nws lub hom phiaj, cov ntaub ntawv, qauv, tshwj xeeb, thiab kev siv. Peb tseem yuav piv nm {- b Cable nrog lwm cov hluav taws xob cov hluav taws xob, pab koj txiav txim siab txoj cai.
Lub hom phiaj ntawm nm - b cable
Nm {- b cable, tseem hu uaTsis - nws yog xim hlau sheathed cable (hom - b), yog feem ntau siv rau:
- Nyob sab hauv tsev xaim hluav taws xob ntawm cov tsev nyob thiab ua lag luam
- Ceg Npe Ceg Rau Teeb Pom Kev Teeb Pom Kev Pom Kev Teeb, Cov Khoom Siv, thiab Cov Khoom Siv
- Tsawg -} rau - nruab nrab fais fab faib sab hauv phab ntsa, plag tsev, thiab qab nthab
Nws qhov tseem ceeb tau txais txiaj ntsig nyob hauv nwsYooj taus thiab kev nyab xeeb ua raws liCov. Tsis zoo li kev ua rog lossis nws yog xim hlau cable, nm {{1} b cable yog kev yooj yim thiab yooj yim rau nruab rau hauv cov chaw zais me me los yog ntoo. Qhov no ua rau nws siv dav tshaj plaws siv cable hauv niaj hnub no Asmeskas kev tsim kho.
Cov ntaub ntawv thiab kev tsim kho NM - b cable
Ib qho nm - b Cable yog ua los ntawm cov khoom siv tseem ceeb hauv qab no:
1.Copper Callcus
- Tus tub ntxhais sab hauv yog ua los ntawm annealed liab qab tooj liab.
- Tooj liab muab kev ua haujlwm siab, durability, thiab corrosion tsis kam.
- Cov qauv qhov ntau thiab tsawg ntawm 14 AWG rau 2 AWG, nyob ntawm kev thauj khoom yuav tsum tau ua.
2.thermoplastic rwb thaiv tsev (PVC)
- Txhua tus neeg xyuas pib yog insulated nrog cov xim - coded polyvinyl chloride (PVC).
- Cov xim xim pab txhawb nqa cov hluav taws xob kub (dub / liab), nruab nrab (dawb), thiab av (ntsuab) xas.
3.Vuav tsis yog - nws yog xim hlau ntaub qhwv (PVC lub tsho)
- Lub ntsej muag sab nraud yog nplaim - tiv taus thiab tiv thaiv tawm tsam kev puas tsuaj.
- Muaj cov xim zoo li daj zoo li daj, dawb, txiv kab ntxwv, lossis grey kom paub qhov sib txawv ntawm cov cuab yeej ntsuas.
4.QLO DABLAY Hlau
- Liab qab lossis ntsuab insulated tooj liab hlau rau kev nyab xeeb hauv av.
Qhov no tsis - nws yog xim hlau ua yog dab tsi ua rau nm- b txawv los ntawm kev teeb tsa lub cev sib txawv thaum tseem ua kom muaj kev nyab xeeb raws liUL Txuj Ci 719thiabNEC (National Electrical Code)yuav tsum tau.
Qhov sib txawv ntawm cov ntaub ntawv siv nyob rau hauv nm - b cable
Kev ua tau zoo ntawm nm {- b Cable yog nyob ntawm covCov Khoom Xaiv:
1.Copper vs. aluminium tus cwj pwm
- Nm {- b yuav luag txhua ib txwm siv tooj liab rau superientity thiab kav ntev.
- Aluminium yog pheej yig dua tab sis tsawg dua, nquag siv oxidation, thiab tsis tshua siv nyob rau hauv nm - b.
2.pvc rwb thaiv tsev zoo
- Siab -}} resistမ်း fes thiab txwv tsis pub muaj hluav taws xob.
- Perman tuaj yeem dhau los ua neeg muaj peev xwm hla lub sijhawm, ua rau kev phom sij kev nyab xeeb.
3.Touter Durability
- Tus qauv nm {{{- b sheathing tsuas yog ntsuas rau cov chaw qhuav.
- Rau sab nraum zoov lossis cov chaw ntub dej, UF {{- b lossis thwn xov hlau yuav tsum tau.
Los ntawm kev nkag siab cov ntaub ntawv sib txawv, cov neeg yuav khoom tuaj yeem xaiv cov khoom kom raug rau lawv qhov project thaum ua kom muaj txiaj ntsigNtev thiab Kev Nyab Xeeb.
