Qhov kev pheej hmoo tiag tiag tsis yog "tus nqi qis." Qhov kev pheej hmoo loj dua yog tau txais cov kab hluav taws xob uas tsis ua raws li tus qauv tsim, daim ntawv pov thawj yuav tsum tau, tus neeg xyuas pib qhov tshwj xeeb, lossis ntev - qhov kev cia siab rau kev ua haujlwm sab nraum zoov.
Hauv qab no yog cov ntsiab lus tseem ceeb uas cov neeg yuav khoom yuav tsum tau kuaj ua ntej tso qhov kev txiav txim.
1. Txheeb xyuas daim ntawv pov thawj, Tsis yog daim ntawv pov thawj xwb
Rau cov hnub ci cables, ntawv pov thawj yog ib qho ntawm thawj yam uas cov neeg yuav khoom yuav tsum tau kuaj xyuas. Cov qauv thoob ntiaj teb feem ntau suav nrog EN 50618, IEC 62930, TÜV ntawv pov thawj, thiab UL 4703, nyob ntawm lub hom phiaj kev lag luam thiab qhov project yuav tsum tau ua.
Ib tus neeg muag khoom ntseeg siab yuav tsum muaj peev xwm muab cov ntawv pov thawj siv tau, cov ntaub ntawv xeem, thiab cov khoom cim meej. Cov neeg yuav khoom yuav tsum tau txheeb xyuas daim ntawv pov thawj los ntawm cov ntaub ntawv pov thawj thaum ua tau, xws li TÜV Rheinland Certipedia lossis UL Product iQ.
Tsis txhob cia siab rau daim ntawv pov thawj PDF lossis cov duab khoom. Tus qauv naj npawb, cable loj, qhov ntsuas hluav taws xob, thiab lub npe chaw tsim khoom yuav tsum phim cov khoom siv tiag tiag.
2. Txheeb xyuas qhov tseeb Cable Standard rau koj lub khw
Kev lag luam sib txawv yuav xav tau cov qauv sib txawv. Rau ntau lub thoob ntiaj teb thiab European -style PV tej yaam num, H1Z2Z2-K cables raws li EN 50618 los yog IEC 62930 feem ntau yog siv. Rau Asmeskas kev lag luam, UL 4703 PV xaim feem ntau xav tau.
Ua ntej lees paub qhov kev txiav txim, cov neeg yuav khoom yuav tsum qhia meej:
- Yuav tsum muaj tus qauv: EN 50618, IEC 62930, TÜV, UL 4703, lossis lwm yam
- Rated voltage: 1000V, 1500V, lossis 2000V nyob ntawm qhov system
- Cable loj: xws li 4mm², 6mm², 10mm², los yog AWG qhov ntau thiab tsawg
- Cov khoom siv hluav taws xob: tinned tooj liab, tooj liab, lossis aluminium alloy
- Daim ntawv thov: rooftop, av-mounted, floating PV, los yog hnyav sab nraum zoov ib puag ncig
Cov kauj ruam no yuav pab kom tsis txhob muaj teeb meem kev ua raws cai thaum lub sijhawm kuaj xyuas lossis teeb tsa.
3. Tshawb xyuas tus neeg xyuas pib thiab cov ntaub ntawv ntxaws
Tus neeg xyuas pib yog ib qho tseem ceeb tshaj plaws cuam tshuam rau ob qho tib si cable kev ua haujlwm thiab tus nqi. Cov neeg yuav khoom yuav tsum paub meej tias lub cable siv tinned tooj liab, liab qab tooj liab, lossis aluminium alloy conductor.
Rau tooj liab hnub ci cables, yuav tsum tau them nyiaj mloog mus rau conductor purity, tiag tiag cross-sectional cheeb tsam, stranding qauv, thiab seb tus neeg xyuas pib ua tau raws li qhov pom zoo tus qauv. Rau aluminium alloy PV cables, cov neeg yuav khoom yuav tsum paub meej tias cov khoom sib txuas thiab kev teeb tsa yuav tsum tau ua.
Cov ntaub ntawv rwb thaiv tsev thiab sheath yog qhov tseem ceeb sib npaug. Hnub ci cables raug tshav ntuj, tshav kub, los nag, av noo, thiab txhua yam kev ntxhov siab rau ntau xyoo. Lub cable yuav tsum muaj qhov tsim nyog UV tiv thaiv, huab cua tsis kam, kev ua haujlwm rwb thaiv tsev, thiab ntsuas kub rau kev siv sab nraum zoov PV.
4. Ua tib zoo mloog rau cable ntev thiab ntim
Kev sib piv tus nqi tuaj yeem ua yuam kev yog tias cable ntev thiab ntim tsis tau lees paub meej. Piv txwv li, ib tus neeg xa khoom tuaj yeem hais raws li 100-meter yob, thaum lwm tus tuaj yeem hais raws li 500-meter lossis 1,000-meter nruas.
Ua ntej xaj, paub meej tias:
- Ntev ib yob los yog nruas
- Ntev ntev
- Nruas los yog thawv ntim txoj kev
- Cov ntaub ntawv sau npe
- Export ntim yuav tsum
- Seb ntoo nruas yuav tsum fumigation
Nrawm ntim thiab ntev yuav tsum tau pab txo cov kev tsis sib haum xeeb tom qab xa khoom.
5. Nug rau ua ntej-Cov ntaub ntawv xa khoom xa tuaj
Rau qhov project yuav khoom, cov ntaub ntawv yog ib feem ntawm cov khoom. Tus kws tshaj lij yuav tsum muaj peev xwm muab cov ntaub ntawv zoo tshaj plaws ua ntej xa khoom.
Cov ntaub ntawv pom zoo muaj xws li:
Cov ntaub ntawv cov khoom
Daim ntawv pov thawj siv tau
Factory test report
Daim duab kos duab
Ntim duab
Batch soj ntsuam cov ntaub ntawv
Cov ntawv ntim khoom
Commercial invoice
Rau kev txiav txim loj, thib peb- kev tshuaj xyuas tus neeg tuaj yeem tuaj yeem npaj ua ntej xa khoom los xyuas cov kab loj, qhov pom, cim, ntim, thiab kom muaj nuj nqis.
6. Txheeb xyuas lub sijhawm xa khoom ntxov
Rau cov neeg ua haujlwm EPC, kev xa khoom qeeb tuaj yeem cuam tshuam ncaj qha rau kev txhim kho kev txhim kho, kev npaj ua haujlwm, thiab daim phiaj - lub sijhawm sib txuas. Cov kab hluav taws xob hnub ci feem ntau tau teeb tsa hauv ntau qhov ntau thaum lub sijhawm tsim kho, yog li kev xa khoom qeeb qeeb tuaj yeem tuav rov qab module thaiv, txuas lub thawv sib txuas, kev sim, thiab kev ua haujlwm.
Ua ntej muab qhov kev txiav txim, cov neeg yuav khoom yuav tsum lees paub qhov kev npaj xa khoom tiag tiag es tsis yog thov rau tus nqi qis tshaj.
Cov ntsiab lus tseem ceeb uas yuav tsum tau kuaj xyuas muaj xws li:
- Tam sim no cov khoom muaj nyob rau cov qauv loj
- Lub sij hawm ua cov khoom siv rau customized specifications
- Kwv yees ntim thiab tshuaj xyuas lub sijhawm
- Shipping txoj kev thiab kwv yees lub sij hawm thauj mus los
- Seb cov khoom xa tuaj ib nrab yog muaj rau cov haujlwm ceev
- Cov ntaub ntawv xav tau ua ntej kev lis kev cai clearance
- Tsis ntev los no rau lub caij ncov, hnub so, lossis chaw nres nkoj congestion
Rau qhov project- raws li kev txiav txim, nws yog qhov zoo dua los qhia cov sijhawm tsim kho nrog tus neeg muag khoom ua ntej. Qhov no tso cai rau tus neeg muag khoom los npaj cov khoom tsim, khaws cov ntaub ntawv, npaj ntim khoom, thiab sib koom ua ke xa khoom raws li lub sijhawm ua haujlwm.
Xaus
Txo kev pheej hmoo ntawm kev yuav khoom tsis yog hais txog kev nrhiav qhov pheej yig tshaj hnub ci cable. Nws yog hais txog kev ua kom lub cable haum, ntawv pov thawj, raug teev, raug ntim, xa raws sijhawm, thiab txhawb nqa nrog cov ntaub ntawv tiav.
Thaum muas lub hnub ci hluav taws xob los ntawm Tuam Tshoj, cov neeg yuav khoom yuav tsum txheeb xyuas daim ntawv pov thawj, lees paub cov qauv, xyuas tus neeg xyuas pib thiab cov ntaub ntawv cov ntsiab lus, qhia meej ntim, thiab npaj cov sijhawm xa khoom sai. Ua haujlwm nrog tus neeg muag khoom uas nkag siab txog cov sijhawm teem sijhawm tuaj yeem pab txo qis kev teeb tsa thiab tiv thaiv tag nrho cov sijhawm ua haujlwm.
Ntawm SINELINK, peb txhawb cov haujlwm hnub ci nrog PV cables, hnub ci txuas, cov khoom siv hluav taws xob, thiab qhov project-raws li kev txhawb nqa khoom. Peb kuj pab cov neeg siv khoom sib koom ua ke xaiv cov khoom lag luam, ntim khoom, cov ntaub ntawv, thiab kev npaj xa khoom, yog li EPC cov neeg cog lus, cov neeg xa khoom, thiab cov neeg teeb tsa hnub ci tuaj yeem txo qhov kev pheej hmoo ntawm kev yuav khoom thiab tsim kom muaj kev nyab xeeb, txhim khu kev qha PV systems.
