Xhhw xaim siv rau hauv cov hluav taws xob hluav taws xob?

1. Dab tsi yog xhhw hlau?

XHhw sawv rau "Hla Polyethylene siab kub-resistant thiab dej-resistant." Nws yog hom xaim hluav taws xob tsim los siv rau hauv cov chaw qhuav thiab qhuav, nrog qhov ntsuas kub tshaj plaws ntawm 90 degree rau 150 qib (302 degree f) nyob rau hauv qhuav ib puag ncig. Tus ntoo khaub lig-txuas polyethylene (xlpe) rwb thaiv tsev muab cov tshuaj tiv thaiv zoo dua, thiab cov hluav taws xob ruaj khov piv rau cov xov hlau pvc-insulated. Qhov no ua rau xhhw zoo tshaj plaws rau cov ntawv thov xav tau, suav nrog cov khoom siv hluav taws xob, kev pabcuam nkag, thiab kev lag luam tshuab.

Cov Nta Tseem Ceeb Ntawm Xhhw Hlau:

XLPE rwb thaiv tsev: Txhim kho kom tiv thaiv kom sov, puas yog, thiab noo noo.

Kev Ntsuas Hluav Taws Xob: Feem ntau ntsuas rau 600V, haum rau feem ntau cov ntaub ntawv tsawg-nruab nrab voltage.

Yooj yooj: Yooj yim dua rau nruab dua li cov hlau sib tw-clad cables.

Kev ceev kev cai: Raws li NEC (National Electrical Code), UL (Underwriters Chaw soj ntsuam), thiab CSA (CANAADIAN Cov Qauv Txheej Txheem).

2. Kev ua tau zoo ntawm XHHW hlau hauv cov ntoo hluav taws xob

Hluav taws xob hluav taws xob yuav tsum tau xaim hluav taws xob uas tuaj yeem kho siab tam sim no, tiv thaiv kev nyab xeeb ib puag ncig ib puag ncig, thiab ua kom muaj kev nyab xeeb ntev. Ntawm no yog li cas xhhw hlau txawj nyob rau hauv cov chaw no:

A. SUPORIES THOIG

Lub XLPE rwb thaiv tsev hauv XHhW hlau tso cai rau nws ua kom muaj txiaj ntsig ntawm cov kub. Piv txwv li,2/9 {1}}} xhhw txhuas hlauthiab2 AWG XHHW Cableyog engineered kom tiv taus cov cua kub tsim los ntawm cov ntawv thov siab tam sim no yam tsis muaj kev ntsuas. Qhov no txo ​​txoj kev pheej hmoo ntawm rwb thaiv tsev rwb thaiv tsev meltdown, ib qho tseem ceeb hauv cov khoom siv hluav taws xob ntim hluav taws xob.

B. Ya noo thiab Tshuaj Lom Zem

Xhhw -2-} Cov nqi sib tw, xws li2 AWG Xhhw -2}} txhuas hlau, tshwj xeeb ua kom cov dej ntws tawm, ua rau lawv haum rau dej noo chaw lossis chaw nyob sab nraum zoov uas hws yuav tshwm sim. Lub rwb thaiv tsev tseem tiv taus roj, acids, thiab alkalis, kom muaj kev ntseeg tau yooj yim hauv kev muaj chaw muaj kev nyab xeeb.

C. Durability thiab Ntev

Aluminium Xhhw xov hlau, suav nrog250 mcm xhhw txhuas, Muab ib lub teeb yuag tseem tab tom hloov kho kom khov kho rau tooj liab. Aluminium lub ntuj Oxide txheej muab corrosion tsis kam, thaum lub XLPE rwb thaiv tsev tiv thaiv lub cev hnav. Qhov kev sib xyaw ua ke no txuas ntxiv lub neej ntawm hluav taws xob sib txuas.

D. Tus nqi-ua hauj lwm zoo

Aluminium Xhhw xov hlau nyiam2/9 {1}} xhhw txhuas hlau 600Vtau cuam tshuam ntau dua thiab pheej yig dua li tooj liab sib npaug. Rau cov haujlwm loj-, qhov no txhais ua cov khoom qis dua thiab cov nqi zog uas tsis muaj kev cuam tshuam.

3. Kev siv XHHW hlau hauv cov hluav taws xob

XHhw hlau yog ib qho staple hauv cov khoom siv hluav taws xob vim nws cov versatility. Hauv qab no yog siv cov xwm txheej feem ntau rau cov kev sib txawv:

Aws 2 / 0 xhhw txhuas hlau 600V

Kev Pabcuam Kev Ua Haujlwm Saib Xyuas: Nqa qib siab tam sim no thauj khoom los ntawm cov nqi hluav taws xob ntawm cov khoom noj rau cov vaj huam sib luag loj.

Feeder Cij: Hais tawm lub zog kom subpanels lossis cov tshuab hnyav.

Muaj Panels: Qhov zoo tagnrho rau ib puag ncig uas yuav tsum muaj corrosion-resistant wireing.

B. 2 AWG XHHW Cable

Ceg Npe: Powers teeb pom kev zoo, HVAC tshuab, thiab sab nraud.

Rov nrhiav: Hloov pauv cov laus dua nrog cov khoom siv hluav taws xob niaj hnub, kub resistant.

C. 250 mcm xhhw txhuas

Cov Khoom Muaj Peev Xwm Panels: Txhawb nqa cov lag luam loj lossis kev lag luam lag luam.

Khoom Noj Qab Haus Huv: Tsis kam tua ntawm cov ntawv thov faus.

D. Xhhw -2} Txhuas Hlau

Sab nraum zoov Panels: Withstands UV kis thiab av noo.

Hars ib puag ncig: Siv rau hauv cov nroj tsuag tshuaj lom neeg lossis chaw siv dej kom huv.

4. Muab cov xhhw hlau rau lwm tus

Txhawm rau hais txog qhov zoo tshaj plaws ntawm XHhw xaim, cia muab piv rau cov kev xaiv ib yam li thhn / thwn thiab xaim hluav taws xob.

Rau cov panels hluav taws xob, XHHW txhuas hlau ntaus ntawv qhov sib npaug ntawm kev ua tau zoo, raug nqi, thiab yooj yim ntawm kev teeb tsa.

5. CODE ua raws cai thiab kev txiav txim siab nyab xeeb

XHhw hlau tau pom dav nyob rau hauv Nec tsab xov xwm 310 thiab UL tus qauv 44. Cov ntsiab lus ua raws cai suav nrog:

Ampacity Ntsuas: 2 / 0 xhhw hlau 600VMuaj cov ampacity ntawm 135A (75 Degree txiav tawm tsam), haum rau feem ntau lub vaj huam sib luag applications.

Conduit compatibility: Tuaj yeem ntsia hauv EMT, PVC, lossis cov tawv nqaij hlau ua kom zoo nkauj.

Kev cog lus: Txhuas XHHW yuav tsum muaj cov tshuaj tiv thaiv oxidant kom tiv thaiv kom tsis txhob muaj Galvanic corrosion.

6. Xaiv cov xhhw hlau rau koj lub vaj huam sib luag

Xaiv cov xhhw variant nyob ntawm cov kev yuav tsum tau ua, ib puag ncig cov xwm txheej, thiab pob nyiaj:

Rau cov nra hnyav: 250 mcm xhhw txhuastxhawb nqa txog 290a.

Rau cov phiaj xwm raug nqi: 2 AWG Xhhw -2}} txhuas hlauMuab cov peev nyiaj siv nyiaj txiag rau ceg txheem.

Rau cov chaw kub-: 2 / 0 xhhw hlau 600VXyaum ua tau kev ua tau zoo hauv cov chaw sov.

7. Txhim kho cov kev coj ua zoo tshaj plaws

Siv cov ntaub pua av compression rau txhuas txiav.

Zam kev ntse los tiv thaiv kev puas tsuaj rwb thaiv tsev puas tsuaj.

Daim ntawv lo xov hlau kom meej meej rau kev saib xyuas yooj yim.
