Photovoltaic DC cables feem ntau yog siv rau kev xa hluav taws xob ntawm DC sab ntawm hnub ci photovoltaic lub zog tsim hluav taws xob. Cov ntawv thov tseem ceeb suav nrog module series kev sib txuas, txoj hlua sib txuas, kev sib txuas lub thawv sib txuas, thiab kev sib txuas inverter.
Nyob ntawm qhov system qauv thiab tso ib puag ncig, tshwj xeeb daim ntawv thov scenarios yog raws li nram no:
Series Kev Sib Txuas Ntawm Modules: Photovoltaic DC cables yog siv los txuas ntau lub hnub ci vaj huam sib luag hauv series los ua ib txoj hlua, yog li ua kom cov zis hluav taws xob. Hauv qhov xwm txheej no, cov kab hluav taws xob yuav tsum raug nthuav tawm sab nraud rau lub sijhawm ntev, lub hnub ci, nag, hluav taws xob ultraviolet, thiab kub hloov pauv.
Parallel Connection nruab nrab ntawm cov hlua thiab nrog DC Distribution Boxes (Combiner Boxes): Ntau cov hlua txuas nrog rau kev sib txuas ntawm DC cables los ua ke tam sim no thiab xa mus rau hauv nruab nrab rau lub thawv sib txuas. Cov kab no feem ntau yog muab tso rau sab nraum zoov kev txhawb nqa lossis hauv av thiab yuav tsum muaj huab cua zoo, tiv thaiv kev laus, thiab kev ya raws.
Kev sib txuas ntawm DC Distribution Boxes (Combiner Boxes) thiab Inverters: Lub zog DC ua ke yog xa los ntawm cov cables mus rau inverter rau AC -DC hloov dua siab tshiab. Tshooj lus no ntawm cable cuam tshuam nrog kev sib kis ntev thiab lub zog siab, xav tau cov kab poob qis thiab siab conductivity stability. Tshwj xeeb photovoltaic cables xws li PV1-F raug pom zoo los xyuas kom meej qhov system efficiency thiab kev nyab xeeb.
Distributed and Commercial/Industrial Photovoltaic Power Stations: Nyob rau hauv lub ru tsev photovoltaic thiab faib cov chaw lag luam / kev lag luam fais fab, DC cables tau dav siv los txuas arrays thiab cov khoom siv inverter. Vim muaj kev txhim kho ib puag ncig (xws li lub ru tsev ntse npoo thiab siab - qhov kub thiab txias), cov cables kuj xav tau cov khoom siv zoo heev thiab siab - qhov kub thiab txias (txog 125℃).
