1. Xhhw Cov Hlau Specifications thiab Cov Ntsuas Kub
XHhw xo txhais tau hais tias nws cov ntaub ntawv rwb thaiv tsev-hla polyethylene (xlpe) -thiab nws tsis kam, noo noo, thiab puas. Raws li kev lag luam qauv,XHhw Hlau yog ntaus nqi rau kev ua haujlwm siab tshaj plaws ntawm 90 degree (194 degree F) nyob rau hauv cov chaw ntub dej lossis qhuavCov. Txawm li cas los xij, lub XHHW -2 variant, uas muaj qhov ua kom muaj qhov kub me, kuj muaj kev sib cuam tshuam ntau dua, tsis muaj kev cuam tshuam dab tsi.
Cov ntsiab lus tseem ceeb muaj xws li:
Kev Ntsuas Hluav Taws Xob: Feem ntau 600V, txawm hais tias qee qhov kev teeb tsa, xws li 2 Awg Tooj Liab XHHW, muaj ntsuas txog li 1000v hauv kev sib sau tshwj xeeb.
Cov Ntawv Qhia Cov Ntawv: Muaj nyob rau hauv tooj liab lossis txhuas. Aluminium cov kev sib txawv, xws li 2 / 0 xhhw, raug nqi rau kev siv cov ntawv thov siab tam sim no.
Kev rwb thaiv tsev: XLPE tau muab cov cua sov zoo heev, tshuaj lom neeg kuj, thiab ntev.
2. Qhov xwm txheej cuam tshuam kub tsis kam
Qhov siab tshaj plaws kev ua siab ntev ntawm XHHW Hlau nyob ntawm:
A. Cov Khoom Siv Rwb thaiv tsev
XLPE tus ntoo khaub lig hla txuas ntxiv txhim kho nws cov thermal endurance piv rau cov tsoos PVC. Nws khaws cia yooj yim ntawm cov kub thiab tiv taus kev tawg, ua rau nws zoo tagnrho rau conduits, kev lag luam tshuab, thiab sab nraum zoov.
B. Tus neeg xyuas loj thiab cov khoom siv
Tooj liab tus neeg xyuas khoom: Piv txwv li, 2 Awg Xhhw Tooj Hlau Rated Rau 1000V tuaj yeem ua tau zoo ampacity (txog 130A ntawm 90 degree) thaum tswj cov cua sov.
Aluminium Cij: 2 / {0 xhhw txhuas hlau, yog feem ntau siv cov khoom siv nkag mus thiab kev pabcuam thiab kev tiv thaiv corrosion.
C. Kev mob ib puag ncig
XHhw cov dej-resistant cov khoom pub nws ua kom ntseeg tau nyob rau hauv cov chaw ntub dej, tab sis ntev ntev raug rau kub siab tshaj 90 degree yuav defade rwb thaiv tsev raws sijhawm.
3. Kev siv XHHW hlau hauv cov hluav taws xob siab-voltage
A. 600V tshuab
Xhhw {{0} Khis Hlau yog dav siv nyob rau hauv 600v kev lag luam thiab kev sib sau ua ke, xws li:
Lub cev muaj zog ncig.
HVAC tshuab.
Cov khoom noj nyob hauv av (vim yog ya raws kev tiv thaiv).
B. 1000V-ntsuas tooj liab hlau
Lub 2 awg xhhw tooj liab variant, ntsuas rau 1000V, yog ua haujlwm hauv:
Hnub ci Farms.
Cov chaw zov me nyuam.
High-voltage fais fab faib khoom.
C. Aluminium Xhhw hauv cov nqi hluav taws xob
2 / {0} Alehw Hlau yog qhov haum rau:
Kev pabcuam nkag mus.
Kev siv hluav taws xob txuas ntxiv (piv txwv li, cua tshuab).
Nqi-rhiab loj-teev cia.
4. Cov Qauv thiab Ua Raws
XHhw hlau adheres rau cov qauv tawv kom ntseeg tau kev nyab xeeb thiab kev ua tau zoo:
UL 44 thiab UL UL 903: Ua pov thawj thermal thiab kev ua hluav taws xob.
NEC (National Electrical Code): Govours cov kev teeb tsa kev teeb tsa, suav nrog qhov kub thiab txias muab tso rau hauv bundled kev teeb tsa.
Cov Qauv Xwm Txheej: Cov tswv yim tsis ntev los no, xws li Tuam Tshoj GB / T 25085 rau cov xov tooj hluav taws xob qib thoob ntiaj teb, cov xov hlau insulated, uas tuaj yeem cuam tshuam rau yav dhau los XHHW cov lus qhia.
5. Muab cov xov tooj liab thiab txhuas xhhw xaim
| Chaw ua uas tsis tau haus | 2 Awg Tooj Liab XHHW (1000V) | 2 / {0}} Alehw (600v) |
|---|---|---|
| Ampacity (90 degree) | ~130A | ~115A |
| Tus nqi | Siab dua | Qi dua |
| Qho hnyav | Hnyav dua | Lub ntais txhuam |
| Corrosion Kuj | Zoo tshaj | Yuav tsum tau tiv thaiv oxidation txheej |
| Cov Ntawv Thov | High-Thov Muaj | Cov nqi hluav taws xob, kev pabcuam kev pabcuam |
6. Yav Tom Ntej Cov Qauv thiab Kev Lag Luam Kev Lag Luam
Lub laub rau hluav taws xob thiab lub zog txuas ntxiv yog kev tsav tsheb xav tau rau cov hluav taws kub uas tsis taus. Cov qauv zoo li iso 19642-5: 2019, uas sib raug zoo ntawm cov ntaub ntawv hauv ntiaj teb thiab kev lag luam zoo li XLPE hauv kev ua tiav ntau dua voltage thiab ntsuas kub. Kev nrhav hauv kev txhim kho thev naus laus zis tuaj yeem txuas ntxiv XHHW cov kev txwv XHHW.
