Nkag siab txog cov hauv paus: Yuav ua li cas cov ntawv txhais tau?
Ua ntej, cia peb txiav txim siab lub nomenclatature. Cov ntawv sau no tau txhais los ntawm National Electrical Code (NEC) thiab qhia cov khoom tshwj xeeb:
T:Thermoplastic rwb thaiv tsev
H:Thaum tshav kub kub - tsis kam (tuaj yeem tiv thaiv kub txog li 75 degree)
HH:Siab kub - tsis kam (muaj peev xwm tiv thaiv kub txog 90 degree)
W:Huab cua thiab dej {- tiv taus (haum rau cov chaw ntub)
N:Nylon sab nraud tsho, ntxiv rau kev tiv thaiv kev siv tshuab ua thiab txiav - los ntawm kev tsis kam
Qhov sib txawv tseem ceeb: ib qho kev sib piv
Thaum cov xov no feem ntau saib zoo ib yam, lawv cov kev ntaus nqi yog qhov sib txawv. Qhov tseeb, koj yuav nquag pom ib lub CABLE STYNED nrog ntau yam kev ntsuas, xws li"Thoj / Thwn"lossis"Thoj / Thwn-2"Cov. Qhov no qhia tau cov xaim hlau ua tau raws cov qauv rau txhua hom teev.
| Yam zoo | Hwj chim | Thwn | Thwn-2 |
|---|---|---|---|
| Max kub (qhuav) | 90 degree | 75 degree | 90 degree |
| Max kub (ntub) | Tsis nyob | 75 degree | 90 degree |
| Huab cua | Cov chaw qhuav nkaus xwb | Qhuav & Damp Thaj Chaw | Qhuav & Damp Thaj Chaw |
| Tseem ceeb lub zog | Kev tiv thaiv kub nyob hauv cov xwm txheej qhuav | Lub chaw ntub dej qhuav haum | Kev ua haujlwm zoo dua: kub tshaj cua sov thiab noo noo tsis kam |
Thwn-2: cov txheej txheem niaj hnub rau kev ua tau zoo dua qub
Raws li lub rooj qhia,Thwn - 2 yog qhov kev xaiv siab tshaj plawsCov. Nws muab cov yeeb yaj kiab zoo tshaj plaws ntawm nws cov neeg ua ntej ntawm nws cov neeg ua ntej: 90℃qhuav ntaus nqi ntawm thhn thiab qhov chaw ntub qhov chaw ntsuam xyuas ntawm thwn, tab sis nrog qhov kev ntaus nqi ntawd ntawm 90 degree. Qhov no ua rau nws yog qhov ntau tshaj plaws thiab yav tom ntej -} Cov ntaub ntawv pov thawj rau yuav luag txhua cov ntawv thov, suav nrog:
Conduit thiab raceways nyob rau hauv ob qho chaw sab hauv thiab sab nraud
Thaj, kev lag luam, thiab kev lag luam ceg circuits thiab tshuab siv tshuab
Thaj chaw muaj qhov kub siab dua lossis noo noo muaj kev txhawj xeeb
Yuav ua li cas xaiv cov hlau zoo rau koj qhov project
Kuaj Hluav Taws Xob Cov Hluav Taws Xob:NEC thiab cov kev hloov pauv hauv zos yog tus thawj coj kawg. Yeej ib txwm ua raws li lawv cov kev xav tau.
Txheeb xyuas ib puag ncig:Yog lub teeb tsa hauv chav ua si qhuav, ib qho chaw nres tsheb damp, lossis sab nraum zoov? Rau tej peev xwm ya raws, thhn tsis yog kev xaiv.
Xav txog lub nra thiab ntsuas kub:Cov cuab yeej siv nrog cov khoom yuav tsum tau muaj txiaj ntsig los ntawm cov qib siab tau tso cai los ntawm Thwn-2's 90 Degree ntsuas feem ntau yuav tsum tau siv qis dua 75℃ampacity kem).
Vim li cas los ntawm qhov chaw ntawm Zhejiang Zhongising Hlau & CABLE Co., Ltd.?
Nkag siab qhov kev xav yog qhov tseem ceeb, tab sis kev ua tau zoo ua tau zoo nyob ntawm kev tsim khoom zoo. NtawmZhejiang Zhongjing, peb tsis cia li xaim hlau; Peb xa cov kev daws teeb meem. Peb liThhn / thwn -} 2 dual-rated cablesyog tsim kom muaj rau cov qauv siab tshaj plaws thoob ntiaj teb (suav nrog UL, CSA, CE, thiab IEC), kom ntseeg tau:
Kev ua tau zoo ib yam:Kho cov ntsiab lus tooj liab thiab rwb thaiv tsev tuab rau lav amporised ampacity thiab kev nyab xeeb.
Qhov ruaj khov:Lub tsho nylon nyuaj tiv thaiv kev tiv thaiv kev tawm tsam thaum lub sijhawm teeb tsa.
Ua raws li:Cov khoom koj muaj peev xwm ntseeg tau kom tau ua kom tau raws li cov kev cai tswj hwm thoob ntiaj teb.
Rau koj qhov project tom ntej, xaiv cov lus qhia meej thiab kev ntseeg siab.Hu rau Zhejiang Zhongjing Hlau & Cable Co., Ltd.Rau cov lus tsocai, thiab cia peb cov kws tshaj lij koj txoj kev vam meej.
