1. Dab tsi yog hom Xhhw thiab Xhhw -2 lules?
Hom XHHW(Hla Linked Polyethylene muaj kev kub siab-resistant dej-resistant) thiabHom xhhw -2Cables tau siv dav hauv cov tshuab hluav taws xob vim lawv cov khoom tsim kho kom zoo thiab versatility. Ob qho tib si yog tsim nrog cov polyethylene sib txuas (XLPE) rwb thaiv tsev, uas muab cov xov hlau ua kom zoo nkauj rau cov xov hlau. Lub ntsiab tseem ceeb lus dag nyob rau hauv lawv cov kev ntsuas kub:
Hom XHHW: Rated txog li 90 degree hauv cov chaw qhuav thiab 75 degree nyob rau hauv cov chaw ntub.
Hom xhhw -2: Ib qho kev hloov kho tshiab rau 90 degree hauv ob qho chaw ntub thiab qhuav, ua rau nws haum rau kev mob heev.
Cov ntaub ntawv no feem ntau siv hauv kev faib khoom siv hluav taws xob, cov tshuab HVAC, kev siv hluav taws xob uas raug cua noo, cua sov, lossis tshuaj lom neeg yog qhov kev txhawj xeeb.
2. Ua xhhw thiab xhhw -2} cables yuav tsum tau conduit?
Qhov kev xav tau rau kev ua haujlwm yog nyob ntawm qhov chaw teeb hluav taws xob thiab cov hluav taws xob hluav taws xob (piv txwv li, lub teb chaws hluav taws xob, lossis nec, hauv Asmeskas). Ntawm no yog qhov tawg:
2.1 Hom XHHW Cable
Cov chaw qhuav: Hauv qhuav, sab hauv tsev ib puag ncig,Hom XHHW Hlautuaj yeem ntsia tau yam tsis muaj kev sib haum yog tias nws yog sau npe tias yog "cov hlau tsim tsev" thiab ua tau raws li cov NEC yuav tsum tau ua. Txawm li cas los xij, kev conduit tseem yuav raug pom zoo rau kev tiv thaiv kev siv tshuab ntxiv.
Cov chaw ntub dej: Thaum siv sab nraum zoov lossis hauv thaj chaw ntub dej, conduit yog feem ntau yuav tsum tau tiv thaiv lub cable los ntawm kev puas tsuaj thiab lub cev puas.
2.2 Hom xhhw -2 cable
Versatility: Ua tsaug rau nws txoj kev ntsuam xyuas kom ntub rau cov chaw ntub dej,Hom xhhw -2 cableYuav siv tau rau hauv ob qho chaw ntub thiab qhuav tsis muaj conduit rau qee qhov xwm txheej. Piv txwv li, kev teeb tsa ncaj lossis teeb tsa hauv cov tais txheej cab yuav raug tso cai nyob rau hauv NEC cov lus qhia, muab cov cable tshwj xeeb rau kev siv.
Yam muaj: Conduit tseem yuav tsum tau nyob rau hauv thaj chaw muaj tsheb ntau, kev txhim kho ib puag ncig, lossis qhov twg lub cable tuaj yeem raug tshem tawm lossis cuam tshuam.
2.3.hth vs. Xhhw
Thhn Xhhw piv: Tsis zoo liHom Xhhw -2 xaim xaub, Thhais (thermopicstic high kub-resistant nylon-coction) xaim hluav taws xob (90 Thhn yuav luag txhua tus yuav tsum tau conduit vim nws txwv tsis kam rau noo noo thiab kev ntxhov siab tshuab. Hauv kev sib piv,Xhhw -2S cov xlpe rwb thaiv tsev thiab cov tsho tuab tuab ntau txo lossis tshem tawm kev sib koom ua ke.
3. Kev ua tau zoo ntawm xhhw thiab Xhhw -2 lules
Cov koob meej ntawmHom XHHWthiabHom xhhw -2stems los ntawm lawv cov kev ua tau zoo hauv cov chaw nyuaj. Hauv qab no yog lawv cov ntsiab lus zoo:
3.1og cov thermal tsis kam
XLPE rwb thaiv tsev tso cai rau cov kab no ua haujlwm los ua haujlwm ntau dua (txog li 90 degree) yam tsis muaj kev txwv. Qhov no ua rau lawv zoo tshaj plaws rau overload-zoo siab lossis kub muaj nqis.
3.2 Txhim kho ya raws thiab tshuaj lom neeg tsis kam
Dej-resistant lub tsho ntawmHom Xhhw -2 xaim xaubTiv thaiv kev haus dej noo, txo txoj kev pheej hmoo ntawm cov kab luv luv hauv cov chaw ntub dej. Ib qho ntxiv, XLPE tiv cov roj, acids, thiab cov kuab tshuaj, ua kom muaj kev ua kom ntev hauv cov tshuaj-hnyav ib puag ncig.
3.3 Durability thiab hloov tau
Tus ntoo khaub lig-txuas Polyethylene rwb thaiv tsev muab cov tshuab puas zoo heev, tiv taus kev txiav, puas tsuaj, thiab cuam tshuam. Qhov no feem ntau tsawg tsawg qhov xav tau rau conduit rau thaj chaw tiv thaiv.
3.4 Tus Nqi Nyiaj Txiag
Los ntawm kev txo lossis tshem tawm cov kev xav tau,Hom xhhw -2 cableKev muab cov peev xwm txo qis thiab cov nqi zog. Nws lub neej ntev kev pabcuam tseem poob qis dua zaus zaus.
3.5 Ua raws li cov qauv kev nyab xeeb
Ob yamHom XHHWthiabXhhw -2Ntsib UL, CSA, thiab NEC cov qauv, kom muaj kev nyab xeeb rau kev nyab xeeb hauv thaj chaw, kev lag luam, thiab kev lag luam.
4. Daim ntawv thov uas conduit yuav xaiv tau
Txhawm rau ua piv txwv txog qhov hloov tau ntawm cov cables, ntawm no yog cov xwm txheej uas conduit yuav tsum ua:
4.1 Kev Sib Tw Sab Nraud
Hom xhhw -2 cableFeem ntau pom zoo rau kev ncaj qha faus hauv av tsis muaj kev pom zoo, muab nws muaj kev tiv thaiv txaus tiv thaiv nas thiab cov phom sij hauv av.
4.2 Cov tais diav ntawd thiab kev sib tw
Hauv cov chaw muaj kev nyab xeeb, cov ntaub pua no tuaj yeem yog taug kev los ntawm cov tais diav cab lossis kev sib tw, kev sib tw, siv zog ua haujlwm tsis tau siv rau kev condent.
4.3 Sab hauv tsev raug khiav
Thaum ntsia tau rau hauv qhuav, cov chaw pheej hmoo qis (piv txwv li, qab nthab kab noj hniav lossis qab phab ntsa),Hom XHHW Hlautej zaum yuav tsis xav tau kev conduit yog cov lej hauv zos.
5. Thaum twg yog qhov tseem ceeb tseem tsim nyog?
Txawm hais tias lawv cov qauv siv hluav taws xob, kev cog lus tseem ceeb nyob rau qee qhov xwm txheej:
Cov Zones High-cuam tshuam: Thaj chaw nrog cov tshuab hnyav, tsheb khiav tawm, lossis kev co.
Corrosive Atmospheres: Cov nroj tsuag tshuaj lom neeg lossis cov ntug dej hiav txwv nrog cov dej qab ntsev.
Kev Xav Kom Zoo Nkauj: Zais cov xov hlau nyob rau hauv cov tsev lag luam.
