Nrog rau lub ntiaj teb tseem ceeb ntawm lub zog huv si, photovoltaic hnub ci tshuab tau nce ntxiv rau ntawm lub ru tsev ntawm tsev neeg thiab cov lag luam. Txawm li cas los xij, cov txheej txheem ntawm lub hnub ci vaj huam sib luag muaj txiaj ntsig thiab kev nyab xeeb tsis yog nyob ntawm lub hnub ci lub hnub ci thiab lub zog hluav taws xob, tab sis kuj tseem muaj cov hlua hluav taws xob uas txuas rau lawv yog qhov tseem ceeb heev. Niaj hnub no, cia peb coj cov ntaub ntawv no los ua qhov chaw pib los tham txog lub luag haujlwm thiab kev xaiv cov ntsiab lus ntawm txhua qhov khoom hauv photovoltaic wiring harnesses.
Cov neeg siv khoom xav tau: Cov kev cai nruj tom qab 25-xyoo kev tiv thaiv huab cua sab nraum zoov
Cov neeg siv khoom German no tsuas yog tsim cov khoom siv hluav taws xob photovoltaic hnub ci thiab yuav tsum tau kho cov khoom siv hluav taws xob rau cov thawv sib txuas (qauv LHPV LH998A-X). Lawv muab peb qhov kev xav tau meej meej:
- IP67 waterproof ntsuam xyuas:Cov hlua hluav taws xob yuav tsum muaj peev xwm ua tau ntev - lub sij hawm txhim khu kev lag luam nyob rau hauv ib puag ncig sab nraum zoov xws li los nag hnyav thiab cov av noo siab, tiv thaiv cov dej infiltration uas tuaj yeem ua rau cov rwb thaiv tsev degradation los yog luv luv Circuit Court.
- Huab cua tsis kam:Nws tuaj yeem ua tau raws li 25 xyoo kev pabcuam sab nraum zoov thiab tiv thaiv kev laus hauv ib puag ncig xws li ultraviolet rays, kub sib txawv, thiab ntsev tsuag.
- TUV Certification:Tag nrho cov cables thiab cov khoom txuas yuav tsum dhau TUV daim ntawv pov thawj, uas yog qhov tseem ceeb ntawm kev nyab xeeb rau cov khoom lag luam photovoltaic nkag mus rau European lag luam.
Tsis tas li ntawd, cov neeg siv khoom tau hais tias cov khoom sib txuas tau sib haum nrog tus qauvMC4 txiv neej / poj niam connectors. Vim li cas MC4 tseem ceeb heev? Hauv PV systems, MC4 tau dhau los ua tus qauv kev lag luam de facto. Nws muaj kev tiv thaiv qis, tus kheej -locking mechanism, thiab kev ua tau zoo ntawm cov dej tsis zoo / plua plav. Siv MC4 xyuas kom meej tias cov hlua tuaj yeem sib txuas nrog feem ntau PV modules, inverters, thiab cov thawv sib txuas hauv thaj chaw. Tsis yog -tus qauv interfaces yuav ua rau lub sijhawm loj thiab raug nqi thaum lub sijhawm teeb tsa. Yog li, MC4 compatibility yog lub hauv paus rau "plug-thiab-play" ua haujlwm thiab ntev{13}}lub sij hawm tuav tswj ntawm ib qho PV system.
Peb qhov kev daws teeb meem: Txhua yam khoom sib raug rau kev sib tw sab nraum zoov
Hauv kev teb rau cov neeg siv khoom xav tau, peb tau muab cov kev daws teeb meem photovoltaic wiring harness, uas nws muaj pes tsawg leeg thiab kev ua haujlwm yog raws li hauv qab no:
-
LHPV LH998A-X Junction Box (Vaj Huam Sib Luag)
Lub thawv txuas txuas txuas cov hlua sab hauv ntawm lub hnub ci vaj huam sib luag thiab cov hlua sab nraud. Lub LH998A-X muaj qhov tsis zoo sab hauv, thiab nws cov diodes bypass tiv thaiv cov hlwb los ntawm kub- cov teebmeem tshwm sim thaum qee qhov ntxoov ntxoo. Qhov taw qhia kev sib txuas ntawm lub thawv thiab lub cable yog tshwj xeeb kaw, nteg lub hauv paus rau tag nrho IP67 waterproof ntsuam xyuas.
2.MC4 Txiv neej / Poj niam Connectors (Terminal End)
MC4 connector ua ntau tshaj li "txuas". Nws cov txiaj ntsig tseem ceeb suav nrog:
- Tus kheej -locking mechanism- Qhov txawv "nias" lees paub qhov kev sib raug zoo, tiv thaiv kev xoob vim cua lossis kev co.
-
Kev tiv thaiv IP67- Nrog lub nplhaib sealing tsis muaj dej, cov khoom txuas tseem nyob hauv dej txawm tias tom qab immersion hauv 1 meter dej rau 30 feeb.
-
Kev tiv thaiv qis - Nyiaj- lossis tin-plated tooj liab tiv thaiv kom ntev - lub sij hawm siab - tam sim no tsis muaj cua sov.
Peb cov MC4 connectors tau tag nrho nrog cov neeg siv khoom uas twb muaj lawm cov cuab yeej thiab cabling layout, tshem tawm qhov xav tau rau adapters.
3.Huab cua-Resistant PV Dedicated Cable
Cov kab hluav taws xob siv ob npaug - txheej txheej rwb thaiv tsev: qis - pa taws halogen- dawb nplaim - txheej txheej sab hauv thiab txheej txheej ntawm UV- tiv taus, ozone - tiv taus irradiated ntoo khaub lig- txuas polyolefin. Cov ntaub ntawv tseem ceeb ntawm kev ua haujlwm muaj xws li:
-
Rated voltage:DC 1500V (tsim rau niaj hnub PV systems)
-
Ua haujlwm kub:-40℃rau +90 degree, nrog rau lub sij hawm luv luv mus txog 120 degree
-
Kev pab lub neej:Kuaj raws li TUV 2PfG 1169 tus qauv, xav tau ntau dua lossis sib npaug li 25 xyoo nyob rau sab nraum zoov
-
UV tsis kam: Passes 720 hour UV aging test, tensile strength retention >80%
4.Zuag qhia tag nrho IP67 Waterproofing
Txhua qhov kev sib tshuam -los ntawm qhov tawm ntawm lub thawv sib txuas mus rau MC4 cov khoom sib txuas- yog kaw nrog kev tiv thaiv dual (lub nplhaib sib khi ntxiv rau potting lossis cua sov- ntsws tubing). Qhov no ua kom cov hlua khi ua haujlwm tau zoo nyob rau hauv cov nag hnyav, siab - lub dav hlau dej siab, thiab txawm tias luv luv - lub sij hawm immersion.
Vim li cas cov neeg siv khoom xaiv Mingching?
Cov neeg siv khoom German thaum kawg tso lawv daim ntawv xaj nrog peb rau ob lub laj thawj tseem ceeb:
- Muaj pov thawj kev paub hauv PV hlua sib dhos- Peb niaj hnub muab TUV- ntawv pov thawj MC4 harnesses rau module manufacturers. Peb paub zoo txog junction box interfaces, cov txheej txheem crimping, thiab cov qauv xeem, muab ib qho kev daws teeb meem los ntawm kev xaiv cov khoom sib txuas mus rau qhov kawg tshuaj ntsuam xyuas.
- Lub sij hawm xa tuaj sib piv lawv cov khoom siv module- PV module tsim ua raws li lub sijhawm nruj qhov rais. Peb qhov kev npaj tsim khoom yooj yim tso cai me me - batch xa khoom sai yam tsis muaj kev cuam tshuam zoo, ua kom cov neeg siv khoom cov qauv xa khoom xa tuaj nyob ntawm txoj kev.
Tsim kom muaj kev ntseeg siab rau koj qhov project PV
Txawm hais tias koj xav tau PV hnub ci cables, junction box harnesses, MC4 connectors los yog TUV-certified solar wires, Xaiv cov khoom tsim nyog thiab cov neeg muag khoom txhim khu kev qha yog ob qho tseem ceeb heev.
Yog tias koj tab tom nrhiav kev sib txuas cov hlua khi rau lub hnub ci vaj huam sib luag modules lossis xav tau kom tau raws li cov dej tsis zoo, huab cua - tiv taus lossis cov ntawv pov thawj, thov koj xav tiv tauj peb txhua lub sijhawm. Thov muab koj tus qauv junction box qauv, ntsuas tam sim no thiab xav tau ntev. Peb cov engineers yuav nrawm nrawm rau kev daws teeb meem rau koj thiab xyuas kom meej tias lub voj voog xa khoom zoo sib xws nrog koj qhov project tseem ceeb.
