UL 83 yog ib qho qauv tseem ceeb muab los ntawm Underwriters Chaw soj ntsuam (UL), Asmeskas cov xov xwm kev nyab xeeb hauv nroog, rau cov xov hlau hluav taws xob hauv hluav taws xob thiab cable. Raws li cov kws sau ntawv rau kev tsim khoom thiab kev kuaj cov xov hlau thiab cov xaim npe rau hauv North America, thermoplastic high kub resistant nylon coated hlau). Thhn cov xov hlau yog dav siv nyob rau hauv cov chaw nyob, kev lag luam vim tias lawv cov kev ua tau zoo, thiab ntau lub hom phiaj cov yam ntxwv.
Cov yam ntxwv yooj yim ntawmThaub Hlau
Thhn xaim yog ib hom hlau coated nrog thermoplastic nylon, uas muaj cov kub zoo siab tiv thaiv thiab noo noo tsis kam. Raws li UL 83 tus qauv kuaj thiab ntawv pov thawj, Thhap hlau muaj cov yam ntxwv hauv qab no:
1.Conductor Hom
Thch Tooj liab hlau: Tooj liab tau siv dav hauv ntau thhn hos thirtity, xws li cov khoom siv tooj liab zoo tshaj plaws ntawm kev siv hluav taws xob ntau.
Th-1hn Allector: txhuas tus cwj pwm yog lub teeb ci thiab tus nqi tshwj xeeb uas yuav tsum txo qhov hnyav, siv cov tshuaj txhuas yog qhov kev daws teeb meem zoo thiab muaj txiaj ntsig.
2. Rwb thaiv tsev txheej txheej
PVC sab hauv rwb thaiv tsev txheej: polyvinyl chloride (PVC) yog siv cov khoom siv hluav taws xob hauv tsev sab hauv, thiab 75 degree c (chaw nres tsheb).
Nylon sab nraud mos: sab txheej txheej ntawm nylon txheej muab tshuaj lom neeg thiab hnav kom haum rau cov khoom siv hnyav xws li conduse lossis xaim hauv cov chaw muaj kev lag luam.
3. Cov lus qhia tshwj xeeb
Thhn Khwv tau muaj ntau yam ntawm cov specifications, los ntawm me me rau cov cab loj loj, kom tau raws li cov zog xav tau. , kom ntseeg tau tias ua tau zoo thiab kev ntseeg tau nyob rau hauv ntau ib puag ncig ib puag ncig. Ntau cov khoom lag luam hlau hlau yog ua tib zoo tsim los ua kom tiav nrog L83 tus qauv, ua rau lawv xaiv zoo tshaj plaws rau ntau yam kev siv. Koj tseem tuaj yeem xauj cov ncauj lus kom ntxaws ntxaws uas tau raws li koj cov kev xav tau nkag siab zoo dua txhua hom qauv khoom. Cov hauv qab no yog qee qhov kev siv tus sawv cev tshwj xeeb.
14 AWG Thhn: Cov xaim xaim no yog qhov zoo tagnrho rau cov ntawv thov tsawg tam sim no xws li lub teeb pom kev zoo thiab cov ntaub so hluav taws xob. Nws tau yooj yim heev hloov tau thiab yooj yim installation thaum ua kom muaj kev nyab xeeb thiab muaj zog faib tawm hauv lub tsev hluav taws xob hauv tsev.
12 Awg Thom Hlau thiab10 AWG Stranded Thhak Hlau: 12 Awg thiab 10 Awg Stranded Thom Hlau Siv Tawm Kho Tooj Liab thiab yooj yim ntawm kev teeb tsa ntawm lub cable, ua rau nws yooj yim siv nyob rau hauv nqaim lossis cov xaim xaim hluav taws xob. 12 AWG Thhn Khij haum rau cov khoom siv hluav taws xob dav dav, thiab 10 WEB tswj cov khoom siv hluav taws xob ntau li ntau dua rau cov khoom siv hluav taws xob ntau dua li cov khoom siv
8 AWG thhn Cable: Siv rau hauv cov tshuab hluav taws xob uas yuav tsum tau muaj peev xwm nqa tau ntau dua thiab muaj peev xwm ua tau zoo dua rau kev ua haujlwm nruab nrab thiab cov khoom siv muaj zog rau cov tshuab hluav taws xob thiab lub teeb hluav taws xob niaj hnub no.
300 mcm thhn tooj liab hlauthiab500 kcmil thhn cable: Cov no yog cov kab ke hnyav uas muaj kev tiv thaiv kom sov thiab tshuaj lom neeg thiab tsim los txhawb nqa cov hluav taws xob tseem ceeb los ntawm kev nqa cov khoom siv siab tam sim no. Lawv tsim rau kev lag luam lag luam thiab ua lag luam kom ua kom tau kev ua tau zoo txawm tias nyob ib puag ncig.
Thhn cov xov hlau tau siv dav hauv cov chaw nyob, ua lag luam vim lawv cov xeeb ntxwv tsis kam, noo noo tsis kam, noo noo kev xav tau rau fais fab kis thiab hlau.
UL 83 YUAV TSUM RAU THHK KHWV
1. Thhak Hlau Qauv
Raws li UL 83 tus qauv, cov qauv yooj yim ntawm THEY cov xov hlau yuav tsum ua raws li cov lus qhia hauv qab no:
Tus kws tshaj lij: Tus thawj coj yuav tsum tau ua los ntawm mos-kos tooj liab lossis txhuas, uas tuaj yeem ntsib UL cov kev xav tau ntawm kev ua haujlwm, lub zog tensile, thiab yooj. Tooj liab tus neeg saib xyuas yog feem ntau yog thia cov hlau stranded, thaum txhuas cov neeg coj tau cov xov hlau feem ntau.
Rwb thaiv tsev txheej: Rwb thaiv cov txheej txheem sab hauv yuav tsum siv cov ntawv PVC uas tau siv cov kab mob nylon yuav tsum tau hnav tsis kam thiab tshuaj lom neeg tawm tsam.
2. Kev ua hluav taws xob hluav taws xob ntawmThhn Cable
Kev ua haujlwm hluav taws xob ntawm Tswv Hluav Taws Xob yuav tsum dhau cov kev xeem nram qab no ntawm UL 83:
Voltage theem: Rated voltage ntawm thhn xaim yog 600v, haum rau thaj chaw, kev lag luam, thiab kev siv hluav taws xob, thiab kev lag luam.
Kev ua kom kub kub: nws yuav tsum muaj peev xwm tiv thaiv kom sov txog 90 degree C nyob rau hauv qhuav ib puag ncig thiab mus txog 75 degree c hauv noo ib puag ncig.
Kev Ntsuas Hluav Taws Xob Hluav Taws Xob: Lub PVC Inner Txheej Txheem Yuav Tsum Tau Kom Yooj Yim Hluav Taws Xob Rwb Thaiv Tsev Ua Kom Paub Tias Rwb Thaiv Tsev Tsis Txaus Siab.
3. Ib puag ncig adaptability ntawm thhn xaim
UL 83 yuav tsum tau nyeem cov xov xwm los tswj kev ruaj khov nyob rau hauv ntau qhov chaw:
Kev ya raws: cov riam phom sab nraud yuav tsum muaj noo noo tsis kam ua kom muaj kev nyab xeeb ntawm cov xaim hluav taws xob ib puag ncig.
Tshuaj lom neeg corrosion: lub nylon sab nraud sheath tuaj yeem tiv thaiv lub yaig ntawm roj, ua rau ultraviolet rays, ua rau cov khoom siv ultraviolet, ua rau tsim tshwj xeeb rau kev lag luam kev lag luam.
Hnav Kuj: Lub nylon sheath yuav tsum tau dhau kev coj mus kuaj mob ulv kom ntseeg tau tias nws tsis yooj yim rau hauv kev sib tw xaim hluav taws xob lossis kev sib txhuam siab.
4. Cov Khoom Siv Neeg Kho Tshuab
UL 83 kuj tau teeb tsa kom muaj tseeb rau cov khoom siv mechanical ntawm.hn Khij:
Yuav tsum muaj lub zog tensile: tus coj lub zog kom muaj zog los tiv thaiv kev tawg thaum nruab.
Dabtsi yog khoov kev ua haujlwm: tshwj xeeb rau 12 thhn thiab 10 thib stranded, zoo hloov tau yog qhov yuav tsum tau los pab txhawb kev sib txuas ua ke complex.
Cov ntawv thov tseem ceeb ntawm Thhn xaim
1. Cov xov xwm dav hlau
Thhn cov xov hlau yog haum rau cov kev xav tau dav dav siv, siv cov hlau uas muaj zog siv sijhawm ntev thiab 12 AWG
2 .Commercial vaj tse
Nyob rau hauv ib puag ncig kev lag luam, 8 AWG Thom Hlau thiab 2 AWG Thom yog cov kev xaiv fais fab cov khoom siv rau nruab nrab cov khoom siv xws li cov cua txias thiab tshuab hluav taws xob thiab hluav taws xob.
3. Kev lag luam chaw
Muaj cov xwm txheej muaj kev daws teeb meem nrog cov xaim hluav taws xob ntau xws li 350 mcm thhn lub tshuab loj loj xws li tau txais cov tshuab hluav taws xob loj kom tau raws li cov kev xav tau.
4. Cov txheej txheem loj dua hluav taws xob
Nyob rau hauv cov dej num loj xws li tshav dav hlau, chaw nres tsheb me, 4 / {} Thnigle Reting thiab ruaj khov fais fab ntawm cov chaw ua haujlwm.
Qhov tseem ceeb ntawm UL 83 daim ntawv pov thawj rauThaub Hlau
UL 83 daim ntawv pov thawj yog qhov tseem ceeb uas yuav tsum tau nkag mus rau hauv kev ua lag luam, tsuas yog cuam tshuam hauv cov hauv qab no:
1. Xyuas kom muaj kev nyab xeeb khoom: UL 83 lees paub wires thhn tau muaj kev nyab xeeb thiab tuaj yeem tiv thaiv cov teeb meem xws li luv luv hluav taws xob thiab overheating.
2. Txhim Kho Kev Ua Lag Luam Kev Sib Tw: COMMIFIFIFE THHK Cov khoom lag luam muaj feem ntau yuav tau txais cov neeg siv khoom ntseeg, tshwj xeeb hauv Asmeskas kev lag luam Asmeskas muaj siab dua.
3. Txhawb txoj kev txhawb siab thev naus laus zis: UP 83 qhov kev ntsuas nruj kom tsim cov tuam txhab uas tau txhim kho lawv cov thev naus laus zis thiab ua lag luam siab dua.
Thahn xaim tau dhau los ua ib qho ntawm cov cable siv dav thoob ntiaj teb vim nws qhov kev ua tau zoo heev, kev ua tau zoo tshaj plaws, thiab ntau lub hom phiaj kev coj ua. UL 83 tus qauv, raws li phau ntawv qhia kev sau ntawv rau nws cov kev tsim khoom thiab siv, ua kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm thhn xaim hauv ntau qhov chaw. Los ntawm 14 Awg Thhais rau 600 kcmil thhn Cable, sib txawv cov xov xwm ntawm cov xov hlau sib txawv raws li peb xav tau ntawm thaj chaw kom muaj kev lag luam. Los ntawm kev sib ntsib cov kev xav tau nruj ntawm UL 83, Thhat tau siv dav siv thoob ntiaj teb, muab kev ntseeg tau rau lub hwj chim kis tau thiab cov hlau.
Thhn cov xov hlau ua los ntawm ntau cov chaw tsim tshuaj hlau ntau dua Seb puas muaj qhov chaw ntub dej los yog qhuav dej. Peb txhawb ntau-qhov tshwj xeeb thiab ntau cov xim customization kom tau raws li qhov xav tau ntawm cov xwm txheej sib txawv. Txais tos tham thiab muab cov ncauj lus qhia ntxaws ntxaws thiab UL daim ntawv pov thawj ntawm Thom Hlau. Peb pab neeg tshaj lij yuav muab cov lus teb rau koj thiab kev txhawb nqa kev tshaj lij!
