Nrog rau kev loj hlob sai ntawm lub photovoltaic (PV) kev lag luam hauv Asmeskas, xaiv cov kab ke zoo rau cov haujlwm tau dhau los ua cov tub ua lag luam, EPC cov neeg cog lus, thiab pab pawg EPC, thiab pab pawg EPC. Raws li cov leeg "leeg" ntawm PV system, cov xaim tsis tsuas yog nqa hluav taws xob tab sis kuj cuam tshuam ncaj qha rau lub kaw lusKev Nyab Xeeb, Lub Neej, thiab Kev nqis peev rov los.
Hauv Asmeskas kev ua lag luam, PV co yuav tsum ua raws liUL QauvCov. Ntawm lawv,Ul44 series cablestau siv dav vim lawv cov kub kub tau ua tau zoo, huab cua tsis kam, thiab kev ua haujlwm rwb thaiv tsev. Ntxiv rau qhov zoo -} paubXHHW-2 thiab RHW-2, cables xws liPV hlau, siv-2, Thwn, Thwn-2, MV-90, thiab MV-105Ntxiv ua si qhov tseem ceeb ntawm cov theem ntawm PV cov phiaj xwm.
Cov kab lus no tau txheeb xyuas qhov yuav tsum muaj Cable yuav tsum muaj ntawm txhua qhov chaw nres tsheb PV - los ntawmModules → Combiner Box → Inverter → Display → Daim Phiaj Sib Nraus{{0- Thiab qhia cov feem ntau siv Ul44 koob clesles hauv kev nthuav dav.
Vim li cas Cable xaiv yog qhov tseem ceeb hauv PV cov phiaj xwm?
Cables yog tus yuam sij rau ntev -}}}}}} tsav ua haujlwm ruaj khov ntawm PV tshuab:
- Kev xyuas xim: Cable rwb thaiv tsev laus, overheating, lossis luv luv kev voj voog tuaj yeem ua rau hluav taws.
- Ua tau zoo: Kev tiv thaiv ntau dhau los yog cov lis dej tsis sib xws tuaj yeem ua rau lub zog poob zog.
- Lub neej: High {- Cov khoom zoo tuaj yeem kawg25-30 xyoos, txuam PV module lifenpan.
Kev ceev kev cai: Hauv Asmeskas, yuav luag txhua tus loj - Scale PVs yuav tsum tau muab cov Cables lees paub nyob rau hauvUl44, ul4703, thiab Ul1072Cov Qauv.
Yog li, txhua theem ntawm PV system yuav tsum muaj txoj cai cable kom ntseeg tau kev ua tau zoo thiab kev ntseeg tau.
