Hauv kev thaiv hluav taws xob hluav taws xob, tw cables, vim lawv txhim kho cov pvc rwb thaiv tsev thiab haum rau 600 volt voltage ntau, tau ua lub neej ntawd kev xaiv rau tsev thiab kev lag luam. Txawm li cas los xij, xaiv txoj cai ntxig cable tsis yooj yim li xaiv cov lus tshwj xeeb ntawm random- paab muaj peev xwm, phim txhua yam phim koj cov kev xav tau tshwj xeeb. Ntawm no yog phau ntawv qhia luv luv los pab koj xaiv qhov yog.
Firstly: Dab tsi yog tw cables? TW (thermoplastic lauj kaub) yog ib qho - tus tseem ceeb cable nrog rau 600 volts rau kev sib sau hluav taws xob. Cov xov hlau tseem ceeb feem ntau ua los ntawm annealed tooj liab- 14 awg specifications yog cov khoom tshwj xeeb yog qhov tseeb, ua kom muaj kev coj ua zoo thiab yooj yim thaum lub sij hawm teeb tsa. Ib tus yam ntxwv tseem ceeb kom nco ntsoov tias yog tus qauv ntxig cable muaj qhov kub tshaj plaws ntawm 60℃hauv cov khoom qhuav thiab ntub dej, uas txiav txim siab lawv cov xwm txheej uas muaj feem xyuam.
Kev siv nyob: ua ntej kev nyab xeeb thiab kev ntseeg
Rau cov hluav taws xob nyob ntawm thaj chaw, kev nyab xeeb, yooj yim ntawm kev teeb tsa, thiab kev sib xyaw nrog cov khoom siv hauv txhua hnub yuav tsum tau txiav txim siab txhua hnub. Nov yog qee cov ntsiab lus tseem ceeb:
Sib txuam thauj nrog AWG Cov Specifications: suav tag nrho cov hwj chim xav tau ntawm lub Circuit Court {}}} awg (20a) lossis 12s) lossis ntau dua cov kab ke. Nyob rau hauv cov chaw nrog txwv chaw zoo li phab ntsa kab noj hniav, nws raug nquahu kom siv multi- strand hlau li lawv tau yooj yim dua ib qho {{} strand xov hlau.
Tsuas yog rau qhov chaw qhuav: Txij li thaum txog tw cable tsis muaj cov khoom siv dej tsis muaj rau sab hauv tsev ntxhua khaub ncaws, cov chav dej, lossis sab nraum zoov uas yuav qhuav. Rau cov chaw ntub dej, siv thw (dej tsis muaj zog ntawm tw) cable.
Paub meej tias qhov pib ua raws: Saib rau UL 83 thiab ASTM B3 / B8, uas qhia tias cov cable cov qauv kev nyab xeeb rau kev siv nyob hauv tsev. Cov khoom lag luam ib txwm muaj tseem muaj cov ntawv sau kom pom tseeb nrog cov ntaub ntawv tsim khoom thiab cov ncauj lus tshwj xeeb.
Kev Siv Lag Luam: tsom rau durability thiab muaj peev xwm
Los ntawm cov chaw ua haujlwm rau cov khw muag khoom muag, cov chaw lag luam muag khoom sib luag tau lub zog hnyav thiab cov chaw muaj ntau dua. Xav txog cov ntsiab lus hauv qab no: suav cov txiaj ntsig hauv qab no: suav nrog cov khoom lag luam siab: cov lag luam feem ntau ua ke (xws li khoos phis tawj, cov tshuab {{1} kev muag khoom). Xa mus rau Ampac Citions: 4 Awg ntxig cable tuaj yeem ua 85 amps tuaj yeem txhawb nqa mus txog li ntawm 230 amps tuaj yeem txhawb nqa cov khoom lag luam thiab lub cim hluav taws xob.
Adapting rau kev teeb tsa txoj hauv kev: cov cable cable yog tsim rau conduits thiab cov tais hlau, uas muaj ntau hauv cov tsev lag luam. Ua kom ntseeg tau tag nrho cov cheeb ntawm cov cable yog haum rau koj conduite loj {}} mm, thaum 250 kcmil muaj ib txoj kab uas hla mus txog 19,5 hli.
Ua ntej zoo thiab durability: Xaiv cov cable nrog cov kab sib txawv (tsis muaj cov kab nrib pleb) thiab ci} Cov paib qhia tau zoo dua qub. Zam kev siv cov pheej yig, cov xaim tsis suav nrog lawv ua rau muaj kev phom sij hluav taws thiab yuav swb rau kev siv tsheb tas mus li.
Daim Ntawv Teev Tseg Zaum Kawg Rau Ib Qho
Daim ntawv pov thawj yog ib qho tseem ceeb: ib txwm txheeb xyuas rau UL 83 thiab UL 1581? Rau kev ua lag luam Suav, kuj ua kom muaj ntawv pov thawj CCC. Kuaj lub cev nqaij daim tawv: siab - Zoo ntxig cable tau muaj kev thaiv thiab cov neeg coj ua, thiab tsis muaj kev cuam tshuam lossis tawg. Tsis txhob xaiv cov cables nrog cov ntawv tsis meej lossis tsis txaus ntseeg cov khaubncaws sab nraud povtseg.
Tham cov tub txawg: Yog tias koj tsis paub meej txog kev thauj xam cov kev ua haujlwm lossis ib puag ncig cov neeg siv hluav taws xob, sab laj cov hluav taws xob uas muaj ntawv pov thawj. Lawv tuaj yeem phim koj nrog cov kev qhia tshwj xeeb cable raws li koj qhov yuav tsum tau ua thiab cov kab hauv tsev hauv cheeb tsam.
Xaiv lub plaub ntug hlua cable yog qhov tseem ceeb nyob rau hauv kom ntseeg tau tias nws cov kev qhia tshwj xeeb phim qhov yuav tsum tau ua. Rau tsev neeg cov tsev neeg, tsom xam yog ntawm kev nyab xeeb thiab haum rau cov kab hluav taws xob hauv sab hauv tsev; Rau kev lag luam, nws yog ntawm muaj peev xwm thiab kav nyob rau hauv cov yeeb nkab nruab. Los ntawm kev them nyiaj rau kev ua raws li, thauj khoom sib txuam, thiab ua tau zoo, koj yuav ua kom muaj kev daws teeb meem siv hluav taws xob ruaj khov thiab txhim khu kev qha kom ntseeg tau.
