1.Thiab Xhhw hlau: muaj pes tsawg leeg thiab cov yam ntxwv tseem ceeb
Xhhw sawv rauHla-Txuas Polyethylene (XLPE) Kev Kub Ntau - thiab Dej Resistant HlauCov. Qhov kev tsim qauv no qhia txog ob qho cwj pwm tseem ceeb:
Hla-Txuas Polyethylene Rwb Thaiv Tsev: Txhim kho kev ruaj khov hluav taws xob, cia cov hlau kom khiav hauj lwm ntau dua kub (mus txog 90 degree hauv cov kev mob qhuav thiab 75 degree nyob rau hauv cov chaw ntub dej).
Dej tiv: Ua rau lub cable haum rau ob qho chaw qhuav thiab qhuav.
Cov khoom siv XHhw hlau zoo tagnrho rau kev ua kom muaj kev cuam tshuam ib puag ncig yog qhov tseem ceeb. Cia peb kuaj seb nws qhov kev ua tau zoo li cas nrog kev yuav tsum tau ua.
2.xhhw xaim hauv kev cog lus: ua raws cai thiab kev siv
Cov xov xwm hluav taws xob hauv tebchaws (NEC) tso cai rau kev siv XHHW hlau hauv Conduit system, muab cov cai teeb tsa teeb tsa. Conduit Hauv qab no, peb tshuaj xyuas cov khoom xyhw tshwj xeeb thiab lawv cov conduit compatibility.
2.1. 3 / {0 xhhw tooj liab 600V: Tiv Thaiv Hnyav-Lub Luag Haujlwm Hnyav
Tus3 / 0 xhhw tooj liab 600vCable yog kev xaiv ruaj khov rau cov ntawv thov siab tam sim no. Cov yam ntxwv tseem ceeb suav nrog:
Roj hmab: Rated rau 225a ntawm 75 degree (NEC rooj 310.16).
Kev Ntsuas Hluav Taws Xob: 600V, haum rau kev lag luam thiab kev faib khoom hluav taws xob.
Kev Siv Conduit: Tau tshaj nrog cov hlau nruj (RMC), hlau nruab nrab (IMC), thiab PVC Conduits.
Cov cable tooj liab tuab tuab thiab XLPE rwb thaiv tsev kom ntseeg tau tias muaj cua sov hauv cov ntaub ntawv, thiab cov khoom lag luam hVAC.
2. {{{{{}} / 0 xhhw xaim: xa cov peev txheej siab dua
Tus4 / 0 xhhw hlau(4 / {0 AWG) muaj ntau dua amepacity-txog 260a ntawm 75 degree. Nws cov ntawv thov suav nrog:
Kev Pabcuam Kev Ua Haujlwm Saib Xyuas.
Feeder Cov Kab Rau Cov Cav Ntau Lawm
Thaub qab lub tshuab hluav taws xob.
Thaum ntsia hauv conduit, 4 / 0 XHHW cov kev tiv thaiv los ntawm cov chaw muaj tsheb ntau uas cov cable kev pheej hmoo tau crushed lossis abraded. Nws cov txhuas sib txawv (4 / {{4 4}} xhhw-al) yog txoj kev xaiv tau zoo rau cov phiaj xwm kev siv nyiaj txiag.
2.3. 500mcm xhhw txhuas: lub teeb ci thiab tus nqi-ua tau zoo
Rau cov hluav taws xob loj sib kis, lub500mcc xhhw txhuasCable muab kev sib npaug zoo ntawm kev ua tau zoo thiab pheej yig. Cov ntsiab lus muaj xws li:
Qho hnyav: Aluminium yog 50% sib dua dua li tooj liab, yooj yim dua kev teeb tsa.
Roj hmab: 310a ntawm 75 degree (nec rooj 310.16).
Corrosion Kuj: XLPE rwb thaiv tsev tiv thaiv kev ya raws thiab tshuaj lom neeg raug.
Thaum txhuas yuav tsum muaj condger loj dua piv rau tus tooj liab, nws tus nqi qis thiab tsim nyog xaiv rau cov nqi hluav taws xob thiab cov nqi hluav taws xob txuas ntxiv.
2.4. Xhhw -2 Txoj kev faus ncaj qha: Dual-Lub Tswv Yim Yooj Yim
TusXhhw -2} Txoj Kev Raug DabVariant yog nyob rau hauv av siv yam tsis muaj conduit. Txawm li cas los xij, nws kuj tseem tuaj yeem raug ntsia hauv Conduit rau kev tiv thaiv ntxiv rau ib puag ncig hnyav. Cov txiaj ntsig tseem ceeb:
Qhov Ntsuas Kub: 90 degree nyob rau hauv ob qho tib si ntub thiab qhuav cov xwm txheej.
Yam ruaj khov: Resistays tshav, roj, thiab roj av kis tau.
Versatility: Tsim nyog rau sab nraum zoov teeb pom kev zoo, xiav kev ua liaj ua teb, thiab cov hnub ci hnub ci.
Siv xhhw -2 hauv conduit yog qhov zoo thaum hloov pauv ntawm cov ntu faus thiab sab saud ntawm cov hluav taws xob.
3.Yog li cas conduit thiab XHHW yog ib qho kev yeej yog kev sib xyaw ua ke
Pairing XHhW Hlau nrog Conduit Amplifies nws qhov kev ua tau zoo hauv peb qhov tseem ceeb:
3.1. Txhim kho kev nyab xeeb
Conduit cov ntaub thaiv npog cabes los ntawm lub cev kev puas tsuaj, txo kev pheej hmoo ntawm luv luv hluav taws xob lossis phom sij txaus ntshai. Rau3 / 0 xhhw tooj liab 600vThiab cov kab ke zoo sib xws, qhov no tseem ceeb hauv kev tiv thaiv kev tiv thaiv dhau los vim rwb thaiv tsev ua txhaum cai.
3.2. Kev ntseeg tau ntev
XLPE rwb thaiv tsev twb tau tiv thaiv kev laus, tab sis conduit ntxiv ib txheej ntawm kev tiv thaiv tawm tsam UV duab, tshuaj, thiab nas. Qhov kev sib xyaw ua ke no ntau caum xyoo ntawm kev pabcuam txhim khu kev qha rau4 / 0 xhhw hlauteeb tsa.
3.3 Ua raws li NEC cov qauv
Tus NEC ua kom haum rau kev siv qee qhov chaw ib puag ncig (piv txwv li, nthuav tawm cov chaw sab nraum zoov sab nraum zoov sab nraum zoov. XHHW ua raws li NEC Tshooj 310 thiab 338 simplaws kev soj ntsuam thiab kev pom zoo.
4.Installation kev coj ua zoo tshaj plaws rau XHHW hauv Conduit
Mus rau kev ua tau zoo:
Loj conduit kom raug: Siv NEC Tshooj 9 lub rooj kom tsis txhob muaj ntau dhau. Piv txwv li, a500mcc xhhw txhuasCable yuav tsum tau 2. {5- nti conduit rau ib tus kws xyuas npe.
Tab tom ua radii: Khov qhov tsawg kawg nkaus khoov rwb radius ntawm 5 x lub conduit txoj kab uas ua kom tiv thaiv kev puas tsuaj rwb thaiv tsev puas tsuaj.
Kev cog lus: Ua kom muaj kev tsim nyog hauv av ntawm cov hlau hlau kom txo cov hluav taws xob hauv hluav taws xob.
