1. Dab tsi yog thhn xaim? CSA ntawv pov thawj yog dab tsi?
1.1 Thaub Hlau
Them sawv ntsug rau "Thermoplastic high kub kub {}}}}}}}}}}}} Cov cua sov {}} kub} Nws cov yam ntxwv tseem ceeb muaj:
Siv rau hauv qhuav lossis me me noo noo
Kev Ntsuas Kub Txog 90℃(qhuav) thiab 75℃(noo)
PVC Rwb Thaiv Tsev thiab Nylon Jacking Tiv Thaiv Txhuam, Roj, Thiab Roj.
Qhov ntsuas hluav taws xob txheem yog 600V, ua rau nws dav siv hauv kev tsim cov hlau.
1.2 CSA Daim Ntawv Pov Thawj
CSA, cov tsiaj ntawv luv rau cov koom haum Canadian cov qauv, yog lub luag haujlwm rau kev tsim cov qauv hluav taws xob thiab cov qauv CSA (xws li CSA C22.2).
CSA daim ntawv pov thawj siv cov txheej txheem ntsuas nruj kom ntseeg tau tias cov khoom lag luam ua raws cov kev cai nyab xeeb thiab kev ua tau zoo.
CSA Mark yog dav lees paub los ntawm Canadian cov tshuaj tiv thaiv hluav taws xob thiab cov koom haum ntsig txog thiab muaj kev hwm siab.
2. Thhais thiab CSA: Cov Qauv thiab Sib Xws
1. CSA C22.2 Tsis muaj . 75 tus qauv
Txhawm rau kom tau txais ntawv pov thawj CSA, Yhaws yuav tsum ua raws li CSA C22.2 tsis muaj . 75}, lub canadian sib npaug ntawm peb ul 83.
Cov tuam txhab tsim khoom tuaj yeem txais CSA -}} Zoo} Pom zoo thhn Cable ntawv pov thawj nyob rau hauv tus qauv no.
Cov:
Tej thhn / thwn {{4 4}} cov khoom lag luam yog sau npe kom sib ntsib ob leeg ntawm UL 83 thiab CSA} Cov Qauv, Lub ntsiab lus lawv yog "Dual-Rated."
Daim ntawv pov thawj no them ntau yam kev ua tau zoo, suav nrog qhov kub thiab txias, noo noo tsis kam, thiab lub zog kho tshuab.
2. Yauj Cable (T90 Cable) Kev tsim qauv hauv Canada
Nyob rau hauv Canadian lag luam, thhn feem ntau hu ua T90 nylon cable. Nws yog qhov siab - kub-} illive thermoplastic kab nrog lub tsho nylon.
Ob lub zog canadian tau hais tawm, "Peb tsis hu nws thhn, peb hu nws t90" (tus qauv Canadian rau Thhn).
Qhov kev sib txawv no qhia txog kev siv cov kev pab ntawm cov lag luam sib txawv, tab sis cov khoom lag luam hauv qab yog tib yam.
3. Qhov tseem ceeb thiab qhov sib txawv ntawm Cable Thhn / Thwn-2 Daim Ntawv Pov Thawj Ob Tes
1. Thws JWN-2 sib txawv
Thhn Cable:UL83 tus qauv, CSA C22.2 tsis muaj . 75 kev xaiv pov thawj.
Kub: 90℃qhuav, 75℃ntub.
Rau kev siv hauv qhuav lossis noo noo ib puag ncig.
Thwn-2 cable:Ib qho kev hloov kho tshiab rau cov puag ncig huab cua, nrog cov qauv raws sib txawv nrog CSA.
Kub: txog li 90℃qhuav thiab ntub dej.
Haum rau noo noo ib puag ncig, xws li cov raj hluav taws xob av, tshuaj ntsuab, thiab thaj chaw ntug hiav txwv.
Feem ntau niaj hnub Thoj cable yog qhov tseeb thwn-2 muaj peev xwm thiab yog li ntawd txiav txim siab dual {{1} - csa).
2. Vim li cas thiaj xaiv cov ntawv pov thawj dual lossis thwn-2 cable?
1.CSA ntawv pov thawj ua kom ua raws li cov khoom ua raws cai thiab kev raug cai nyob rau hauv Canada, thaum tseem tab tom siv nyob rau hauv Cross- Bycdit Promers thoob plaws North America.
2.Qhov-2 muaj qhov zoo hauv cov chaw noo noo, ntsuas kub siv hluav taws xob ntau yam, thiab txhim kho kev nyab xeeb.
Ntau yam, nws txo cov lus nug cov lus nug thiab pab txhawb kev xaiv sib koom tes.
4. Cov txheej txheem ntawm cov ntawv pov thawj nrog cov qauv txheej txheem
1. CSA Cov txheej txheem ntawv pov thawj (noj cov khoom siv hluav taws xob hluav taws xob ua piv txwv)
Kev kuaj thov: Cov khoom xa tuaj rau CSA chaw soj ntsuam rau cov khoom siv, hluav taws xob, cov tshuab ntsuas kub, thiab hluav taws kev sim tshuaj.
Cov Qauv Qhia Ntawv Pov Thawj: Ua raws cai yog ua tawm tsam Canadian hluav taws xob code (CEC) thiab CSA C22.2 cov qauv ntawm cov qauv.
Tom qab tau txais ntawv pov thawj, cov khoom tuaj yeem cim nrog CSA Mark thiab tej zaum yuav suav nrog cov cuab yeej lees paub raws li cov cai hauv zos.
2. Canadian hluav taws xob code (CEC)
CEC yog txoj hlua khi hluav taws xob muab luam tawm cov ntaub ntawv tshaj tawm los ntawm CSA. Tus 26th tsab ntawv tau raug tso tawm thaum Lub Peb Hlis 2024.
CEC yog txheej txheem raws li nram no: Ntu I (Ntu Kev Nyab Xeeb), thiab Tshooj IV (Lub Hom Phiaj {{{{{}} {{}}} {}} {}} {{}} {}} {}} {}} {}} {}} {}} {}} {}} {}} {}} {}}} {}}}} {}} {}} {}} {}} {}}} {}} {}} {}}} {}} {}}} {}} {}} Kev siv cov neeg siv tshwj xeeb).
CEC yuav tsum muaj cov khoom lag luam uas ruaj khov los ua raws li Ntu II Cov Qauv (xws li CSA C22.2 Tsis . 75).
5. Cov lus pom zoo xaiv thiab txiav txim siab
1.When using THHN wire in Canadian projects, please confirm that the product is certified to CSA C22.2 No. 75 or marked as CSA-approved.
2.Cov chaw ntub dej, thwn {- 2 (dual-ntawv pov thawj los ntawm CSA thiab UL rau cov chaw ntub dej) yog qhov zoo dua.
3.Yog koj tau ntsib cov qauv "Thhais" uas tsis muaj CSA kos thaum yuav khoom, nug cov khw rau cov ntaub ntawv pov thawj lossis xaiv cov khoom pov thawj hloov.
4.Nimno tau hu xov tooj sib txawv: Canada tau hu nws T-90, thiab thaum lub sijhawm no tseem siv sab nraud ntawm cov cai, nws cov lus sau nrog thhn yuav tsum to taub.
5.Txhua txoj kev hla kev hla dhau- ciam teb lossis cov phiaj xwm thoob ntiaj teb, nws raug pom zoo rau yooj yim rau cov khoom thiab kev tswj hwm ua raws.
