1.Ub Xhhw thiab Xhhw -2} cables
Ua ntej dhia mus rau kev txiav cov txuj ci, nws tseem ceeb kom nkag siab txog cov khoom ntawmHom XHHW Hlauthiab nws cov kev hloov kho tshiab,Hom xhhw -2 cable.
Hom XHHW Hlau:
Nyob rau 90 degree nyob rau hauv cov chaw qhuav thiab 75 degree nyob rau hauv cov chaw ntub dej.
Nta hla-txuas Polyethylene (XLPE) rwb thaiv tsev rau tshuaj thiab kub ua hauj.
Feem ntau siv nyob rau hauv Conduit Systems, cov ntawv thov nkag nkag, thiab xaim hluav taws xob.
Hom xhhw -2 cable:
Ib qho kev hloov pauv hloov pauv rau 90 degree hauv ob qho tib si qhuavthiabntub huab cua.
Haum rau kev ncaj thiab cov chaw muaj nrog cov dej noo ntau dua.
Feem ntau nyiam rau kev teeb tsa sab nraum zoov thiab hauv cov khoom noj hauv qab.
Xhhw 1AWG (1 goosge):
Lub thicker sib txawv tsim rau kev siv cov ntawv thov high.
Yuav tsum tau cov cuab yeej tshwj xeeb rau kev hle thiab txiav vim nws tus neeg kos loj loj.
Cov cables sib ntsib ntawm nec (teb chaws hluav taws xob) cov qauv) cov qauv), tab sis kev txiav tsis ncaj ncees yuav ua rau lawv ua tau zoo thiab muaj kev nyab xeeb.
2.tools thiab cov khoom siv xav tau
Los txiav tawmHom Xhhw -2 xaim xaublossisHom XHHW HlauHauv lub thawv hlws ris, sib sau ua ke hauv qab no:
Lub thawv hlws ris(Ul-npe, qhov loj me rau ib nec 314.16)
Hlau Sawb Hlau(ntsuas rau xhhw rwb thaiv tsev)
Hlab Txuas(anti-luv bushings rau cov thawv hlau)
Lub davhlau ya nyob twg los yog hlau ceev(sib haum nrog xaim gauge)
Torque Ntsia Hlau(rau meej zawm)
Thaum Tshav Kub Kub-Ntsug Tubing(Yeem, rau ntxiv kev tiv thaiv noo noo)
Grounding npua this(rau kev sib raug zoo)
3.Tep-los-Kauj Ruam Txiav Cov Txheej Txheem
Kauj ruam 1: Npaj lub thawv hlws ris
Xaiv lub thawv loj txaus kom haum rau covHom xhhw -2 cablelossisXhhw 1AWGsaib xyuas cov neeg. NEC yuav tsum muaj tsawg kawg 6 ntiv ntawm tus neeg xyuas tshiab ntev hauv lub thawv.
Rau cov thawv hlau, nruab los tiv thaiv bushings luv los tiv thaiv rwb thaiv tsev kev puas tsuaj los ntawm cov npoo ntse.
Kauj ruam 2: Sawb lub cable rwb thaiv tsev
Siv cov hlau hlau ntse kom tshem cov tsho sab nraud ntawm covHom XHHW HlauCov. Zam kev tsis pub dhau tus neeg sab hauv.
RauXhhw 1AWG, xav txog cov kab txaij qeeb dua los lis cov rwb thaiv tsev tuab.
Kauj ruam 3: Kev ruaj ntseg rau cable
Fasten lub cable rau lub thawv hlws rau uas siv cov ntawv pom zoo lossis txuas. Qhov no tiv thaiv kev sib zog ntawm cov ntsiab lus txiav.
Kauj Ruam 4: Kev Txiav Txim Siab
Rau cov txu:
Ntswj tawm ntawm cov neeg xyuas kev coj mus kaw kom nruj thiab ruaj ntseg nrog cov hlau ceev ntsuas rau cov xaim loj.
RauXhhw -2 cableHauv qhov chaw ntub, thov cov dej ntws tawm ntawm cov nyom.
Rau lub davhlau ya nyob twg:
Crimp Lugs mus rau stripped kawg siv lub pob hluav taws xob hauv qab. Lub davhlau ya dav hlau rau cov chaw tsim khoom tshwj xeeb.
Kauj Ruam 5: Grounding
Txuas ib qho groundtail rau lub thawv hlws ris (yog tias hlau) thiab khi nws mus rau Circuit Coal hlau.
Kauj Ruam 6: Kev kuaj kawg zaum kawg
Xyuas kom muaj cov neeg coj mus muag, kom nruj kev nyem, thiab ua raws li lub thawv sau cov kev txwv (NEC 314.16 (b)).
4.Common yuam kev kom tsis txhob
Tsis quav ntsej lub thawv ntim cov kev txwv: Overfilling ib lub thawv hlws ris nrogXhhw 1AWGCov xov hlau tuaj yeem ua rau overheating.
Tsis raug stripping: Puas rwb thaiv tsev nyob rauHom Xhhw -2 xaim xaubnce cov kev pheej hmoo luv luv.
Xoob lub hom phiaj: Lub zog tswj hwm lossis cov txiv ntoo ua rau arcing thiab cov phom tua hluav taws.
5.Yog li cas xaiv Xhhw -2 dua tus qauv xhhw?
Hom xhhw -2 cablemuaj kev hloov pauv zoo tshaj plaws thiab noo noo tsis kam, ua rau nws zoo tagnrho rau ib puag ncig sab nraum zoov lossis kev tsim kho kom huv. Nws 90 degree ntub ntsuas kev ua raws li cov cim hluav taws xob ua raws li cov khoom siv hluav taws xob niaj hnub no thiab HVAC.
