1. To taub XHHW Hlau: Muaj pes tsawg leeg thiab cov yam ntxwv tseem ceeb
XHHW (Cross-txuas Polyethylene siab kub thiab dej-resistant) hlau muaj rwb thaiv tsev rwb thaiv tsev thiab kev yoog tau. Nws cov thawj cheebtsam muaj xws li:
Tus saib xyuas: Feem ntau ua los ntawm tooj liab lossis txhuas, xhhw tus cwj pwm tau tso tseg rau kev hloov pauv tau.
Kev rwb thaiv tsev: Tus xhhw rwb thaiv tsev muaj cov ntoo khaublig sib txuas nrog polyethylene (xlpe), uas muaj cov hluav taws xob zoo dua thiab noo noo tsis kam.
Cov xov xwm hluav taws xob hauv tebchaws (nec) Categores xhhw hlau siv rau hauv ob qho chaw qhuav thiab ntub, nrog qhov ntsuas kub thiab muaj 75 degree hauv qhov chaw ntub dej. Cov khoom no ua rau nws xaiv qhov tseem ceeb rau kev ua lag luam, kev lag luam, thiab cov xov hluav taws xob.
2. XHHW Rwb thaiv tsev: Lub hauv paus ntawm kev ntseeg tau
TusXhhw rwb thaiv tsevyog tus qaum qaum ntawm xaim kev ua tau zoo. Hla-Txuas Polyethylene Undergoes Ib Tug Txheej Txheem Tshuaj uas txhim kho nws cov qauv molecular, uas ua rau:
Kev tiv thaiv kub: Withstands kub txog 90 degree, txo txoj kev pheej hmoo ntawm rwb thaiv tsev kev cawm dim hauv cov tsheb thauj khoom siab.
Ya raws tsis kam: Qhov zoo tagnrho rau cov chaw ntub dej, suav nrog sab nraum zoov thiab sab nraum zoov thiab nyob hauv av.
Kev Siv Khoom Siv thiab Ua Txhuam Tuag Ua: Tiv thaiv cov neeg xyuas khoom los ntawm cov roj, cov kuab tshuaj, thiab hnav lub cev.
Cov yeeb yam no tau kom muaj kev ntseeg tau ntev, txawm nyob hauv ib puag ncig hnyav. Txawm li cas los xij, cov ntawv thov hauv av yuav tsum muaj kev txiav txim siab ntxiv, xws li kev ua tau zoo thiab corrosion tsis kam.
3. XHHW MC Cable: Cov Khoom Siv Ua Ntej
XHHW MC (HLAU-CLAD) CABLEUa ke ua ke xhhw tus cwj pwm nrog cov hlau tiv thaiv hlau, feem ntau aluminium lossis hlau. Qhov kev teeb tsa no muab:
Txhua yam kev tiv thaiv tiv thaiv punctures thiab crushing.
Ua-nyob rau hauv kev ua vaj loog hauv av los ntawm cov hlau armor.
NEC muab tso rau cov hlau riam ntawm MC cable los ua cov khoom siv grounding (egc) yog tias nws ua tau raws li qhov yuav tsum tau ua (NEC tsab cai (NEC tsab xov xwm Nyob rau hauv cov xwm txheej zoo li no, XHHW MC Cable yuav ua tau zoo txhawb av lub sijhawm thaum siv zog lub rwb thaiv tsev.
4. Xhhw hauv av thiab ncaj qha faus cov ntawv thov
Xhhw nyob hauv avKev txhim kho yog ib qho vim yog cov rwb thaiv tsev tsis kam rau noo noo thiab av paug. RauXhhw Hlau Ncaj Ncees, NEC ua raws li kev ua raws nrog kab lus 300.5, uas qhov kev xav tau ntawm qhov teeb meem tob thiab kev tiv thaiv lub cev puas.
Cov ntsiab lus tseem ceeb muaj xws li:
Tsis tas yuav conduit rau hauv ntau cov xwm txheej, txo lub sijhawm thiab cov nuj nqis.
Kev ua tau ntev ntev hauv noo lossis corrosive xau.
Thaum XHHW tsis muaj nyob hauv cov xaim xaim hauv av, nws cov rwb thaiv tsev muaj zog kom ua kom cov txheej txheem hauv qab hauv tib lub kaw lus nyob twj ywm. Piv txwv li, ib qho kev saib xyuas hauv av cais (piv txwv li, tooj liab) tuaj yeem ua ke nrog XHHW cov xov hlau hauv kev thov faus neeg.
5. Khab Xhhw tus cwj pwm siv rau hauv av?
Cov txheej txheem av yuav tsum ua kom tiav cov qauv nruj rau kev ua haujlwm, corrosion tsis kam, thiab txheeb xyuas. Raws li NEC tsab xov xwm 250, cov hauv paus hauv tsev yog feem ntau:
Liab qab lossis insulated.
Pom los ntawm ntsuab lossis ntsuab-nrog-daj-rwb thaiv tsev rwb thaiv tsev.
Xhhw tus cwj pwmFeem ntau yog insulated hauv cov xim dub, liab, lossis lwm yam xim, uas tsis tau raws li NEC cov xim uas yuav tsum tau ua rau av. Txawm li cas los xij, XHHW tuaj yeem siv los ua ib feem ntawm cov hauv paus hauv av hauv cov ntsiab lus:
Khoom Siv Hluav Taws Xob (EGC): Thaum ntsia tsis pub dhau ib lub MC cable, cov hlau sheath tuaj yeem ua haujlwm li EGC, thaum XHHW hlau nqa khoom nqa tam sim no.
Kev Ntxiv Av: XHHW yuav siv tau txuas nrog cov hlau hluav taws rau kev tiv thaiv ntxiv rau kev tiv thaiv.
Txwv tsis pub muaj xws li:
XHHW Rwb thaiv tsev tsis muaj kev ntsuas rau kev siv ncaj qha raws li cov av hluav taws xob hluav taws xob (gec).
Cov xim muaj xim muaj xim rau nws txwv tsis pub nws siv lub hom phiaj hauv av.
6. Qhov zoo ntawm XHHW hlau hauv cov tshuab hluav taws xob
Tshaj li hauv av, Xhhw txawj ntse nyob rau hauv ntau daim ntawv thov:
Lub tsev lag luam: Powers teeb pom kev zoo, HVAC, thiab tshuab.
Cov Chaw Muaj Cov Vaj Tse: Tiv thaiv kom sov thiab tshuaj nyob ze cov cuab yeej hnyav.
Hnub No Tseem Ceeb Systems: Haum rau hnub ci ua liaj ua teb thiab cua tshuab cua.
Nwsncaj qha fausmuaj peev xwm tshem tawm qhov xav tau kev conduit hauv av khiav, thaum lubXhhw rwb thaiv tsevUa kom muaj kev nyab xeeb nyob hauv qhov chaw ntub dej xws li hauv paus thiab cov khoom hloov.
7. Txhim kho cov kev coj ua zoo tshaj plaws rau XHHW hlau
Mus rau kev ua tau zoo:
Ua raws li cov lus qhia nec rau qhov tob ntawm qhov tob thiab kev siv kev sib haum.
Siv cov txuas txuas ntxiv rau kev txiav kom tiv thaiv kev puas tsuaj rwb thaiv tsev puas tsuaj.
Khub xhhw nrog ib tus neeg ua yeeb yaj kiab ua ke hauv cov tshuab tseem ceeb.
RauXhhw mc cable, xyuas kom cov hlau sheath tau raug sib raug zoo rau grounding terminals.
