1. Taw qhia txog XHhw Cable: LAWV THIAB COV NYIAJ
XHHW sawv rau "Hla Linked Polyethylene muaj kub kub-resistant dej tsim rau ob qho qauv hluav taws xob thiab kev siv sab nraud thiab sab nraum zoov. Nws rwb thaiv tsev muaj cov ntoo khaub lig-txuas nrog Polyethylene (XLPE), uas muaj cov xov hlau tshiab rau ib txwm muaj PVC-insulated xaim. Xhhw cables muaj nyob rau hauv ob tug thawj coj los saib xyuas:Xhhw Tooj LiabthiabXHHW Txhuas Hlau, txhua tus muaj qhov zoo sib xws.
Cov Nta Tseem Ceeb Ntawm Xhhw Cable
Kub tiv thaiv: Rated txog 90 degree hauv cov xwm txheej qhuav thiab 75 degree nyob rau hauv ib puag ncig ntub dej.
Kev Ntsuas Hluav Taws Xob: Cov khoom lag luam sib txawv muaj xws liXhhw -2 tooj liab 600vthiab2 AWG XHHW Txhuas Hlau 1000V, Catering rau qis- thiab nruab nrab-cov ntawv thov.
Yam ruaj khov: Tiv thaiv kom ya raws, tshav ntuj (UV hluav taws xob), thiab puas, ua rau haum rau cov chaw hnyav.
Cov khoom siv no ua rau XHhw Cable yog ntau yam kev xaiv rau kev ua lag luam, kev lag luam, thiab xaim ntawm lub nroog. Tab sis nws ua li cas hauv lub nruab hnub ci zog?
2. Hnub ci vaj huam sib luag tshuab: cov kev yuav tsum tau thiab cov nyom
Hnub ci muab kev xav thov cov xaim uas tuaj yeem tiv taus huab thaum tswj kev ua tau zoo. Qhov tseem ceeb yuav tsum muaj xws li:
High Voltage Tuav: Hnub ci tsaj feem ntau ua haujlwm ntawm 600V-1000V DC, xav tau cov kav hlau uas xav tau nrog cov tshuaj voltion txaus.
Kev hloov pauv kub: Cov xov hlau tau raug rau lub hnub ncaj qha, kub los ntawm panels, thiab sub-ncia qhov kub.
Ib puag ncig tsis kam: Noo noo, UV kis, thiab tshuaj lom neeg corrosion (piv txwv li, los ntawm cov khoom siv vov tsev) yog cov kev sib tw ntau.
Yooj taus thiab yooj yim ntawm kev teeb tsa: Xaim yuav tsum khoov ib ncig ntawm cov vaj huam sib luag thiab cov khoom ua kom tsis muaj rhiav thaiv kev puas tsuaj.
Ua tsis tiav kom ua tiav cov kev xav tau no tuaj yeem ua rau tsis muaj zog, kev nyab xeeb, lossis lub sijhawm poob haujlwm.
3. XHhw Hlau hauv Hnub Ci Kev Siv: Qhov zoo thiab txwv
3.1 Xhhw -2 tooj liab 600V: qhov kev xaiv txhim khu kev qha
Tooj liab tus neeg saib xyuas yog tus qauv kub rau hluav taws xob vim lawv lub siab ua haujlwm thiab corrosion tsis kam. TusXhhw -2 tooj liab 600vKev sib txawv yog qhov zoo tagnrho rau cov ntawv thov cov kev siv hnub ci tsawg, xws li cov chaw nyob hauv tsev lob. Cov txiaj ntsig muaj xws li:
Muaj Zog Tiv Thaiv: Minimizes lub zog poob dhau qhov kev ncua deb.
Ua raws NEC cov qauv: Pom zoo rau kev siv nyob rau hauv qhov chaw ntub thiab conduit systems.
Ntev Nqa Pob: Tooj liab tus oxidation tsis kam ntseeg ruaj khov nyob rau sab nraum zoov chaw.
Txawm li cas los xij, tooj liab tus nqi siab dua yuav cuam tshuam cov phiaj xwm-paub meej pem.
3.2 XHHW txhuas hlau: ib qho kev xaiv tau zoo nqi
Aluminium Cijtsam, xws li2 AWG XHHW Txhuas Hlau 1000V, muab ib lub teeb yuag, pheej yig cov teeb meem rau cov kev sib tw loj hnub ci. Cov ntsiab lus muaj xws li:
Cov nqi qis dua cov nqi: Aluminium yog ho pheej yig dua tooj liab.
High Voltage Peev: Tus1000V Kev NtsuasCov khoom siv hluav taws xob-teev hnub ci nruab hnub ci.
Lub Hnav Txom Nyem: Txo cov qauv txheej txheem ntawm cov tshuab mounting.
Txawm li cas los xij, txhuas yuav tsum muaj kev txiav tawm kom tiv thaiv oxidation thiab ua kom pom tseeb. Siv antioxidant gel thiab ul-teev cov txuas yog qhov tseem ceeb.
3.3 Muab piv cov tooj liab vs. aluminium nyob rau hauv lub hnub ci
Tus nqi: Aluminium yeej rau kev teeb tsa loj; Tooj liab zoo dua rau me dua, cov teeb tsa siab ua haujlwm siab.
Yam ruaj khov: Tooj outperforms txhuas hauv corrosion tsis kam.
Kev teeb tsa nyuaj: Aluminium xav tau ntau meticulous kov kom tsis txhob kub me ntsis.
4. Kev Kawm Kev Cai: 2 AWG XHHW Txhuas Hlau 1000V Hauv Kev Ua Haujlwm-teev Hnub Ci Farms
50mw hnub ci liaj teb hauv Arizona xaiv rau2 AWG XHHW Txhuas Hlau 1000VTxhawm rau txuas nws cov photovoltaic arrays. Qhov kev txiav txim siab tau tsav los ntawm:
Voltage yuav tsum: Tus 1000V ntaus nqi sib phim lub kaw lus DC cov lus sib txuas.
Nqi txuag: Aluminium txo cov nqi hluav taws xob los ntawm 40% piv rau tooj liab.
Ib puag ncig resilience: XLPE rwb thaiv tsev withstood suab puam cua sov (txog 50 degree) thiab xuas tes ua.
Kev soj ntsuam kev teeb tsa tshaj tawm tsis muaj qhov tseeb voltage poob lossis rwb thaiv tsev dim kev tom qab ob xyoos, kev xaiv qhov kev xaiv.
5. Txhim kho cov kev coj ua zoo tshaj plaws rau xhhw cable hauv lub hnub ci
Txhawm rau kom ua tau zoo thiab kev nyab xeeb:
Siv cov conduit kom zoo: Tiv thaiv kom muaj kev puas tsuaj rau lub cev thiab UV kis.
Tsis txhob muaj kev sib tw: Xyuas kom muaj kev sib raug zoo los tiv thaiv kev kub heev.
Ua raws li cov lus qhia nec: Vim li ntawm Tshooj 690 (hnub ci photoovoltaic tshuab) rau cov xaim sizing thiab derating.
Soj ntsuam kev txiav: Nquag xyuas txhuas kev sib txuas rau oxidation.
6. Xhhw vs. Lwm lub hnub ci ntsa iab: thhn, pv hlau, thiab siv -2
Thaum XHHW Cable yog ntau yam, hloov zoo li PV hlau thiab siv {-2 yog cov qauv siv hnub ci tshwj xeeb. Qhov sib txawv tseem ceeb:
PV hlau: Muaj ntau dua yooj yim thiab tshav ntuj tiv taus tab sis ntawm tus nqi hwm.
Siv -2: Rated rau Kev Pabcuam Av Hauv Av Nkag Tab sis tsis muaj XHHW lub qhov chaw ntub dej.
Hwj chim: Txwv kom qhuav, sab hauv tsev ib puag ncig, ua kom nws tsis zoo rau feem ntau hnub ci teeb tsa.
Xhhw strikes qhov sib npaug ntawm cov nqi, durability, thiab kev yoog tau, tshwj xeeb yog thaumXhhw -2 tooj liab 600vlossis2 AWG Aluminium 1000vCov hom sib txawv tau xaiv.
7. Yav Tom Ntej Tiam: XHHW Cable Hauv Tom ntej-Gen Ntxiv Zog Hluav Taws Xob
Raws li hnub ci thev naus laus zis hloov pauv, yog li ua kev xav tau. Cov qauv hluav taws xob muaj xws li:
Kev Ntsuas Ntau Cov Tshuab: 1500v hnub ci arrays yuav tsav tsheb thovXHHW Txhuas Hlaunrog kev txhim kho rwb thaiv tsev.
Ntse Daim Ntawv Sib Tw: Xhhw lub durability txhawb iot-enabled soj ntsuam cov tshuab.
Rov qab tau: Aluminium's eco-friendly profile dlhos nrog cov hom phiaj kev lag luam kev lag luam.
Hauv kev sib tw khiav hluav taws xob Asmeskas cable ua lag luam,Dongguan Ntau Ntau Hlau & Cable Co., Ltd.sawv tawm. Peb cov kev sib txuas ntau lawm tau huv thiab ua rau peb cov neeg ua haujlwm muaj kev tawm tsam ntawm 1.3 lab meters ntawm cov zaub mov zoo hauv ib hlis. Peb cov khoom tau dhau los ua ntau daim ntawv pov thawj xws li UL83 thiab PC4. Piv txwv li, NM-B CABLE ntsib tus qib siab Asmeskas cov qauv hauv hluav taws thiab noo noo tsis kam. Nyob rau tib lub sijhawm, peb ua haujlwm ncaj qha nrog cov khoom siv raw khoom kom txo cov khoom lag luam hauv nruab nrab thiab txo cov khoom lag luam Asmeskas kom txaus siab rau cov khoom siv zoo ntawm cov nqi qis.
