Lub luag haujlwm tseem ceeb ntawm photovoltaic DC cables yog xa cov hluav taws xob DC tsim los ntawm hnub ci modules thiab xyuas kom ntev - lub sij hawm ruaj khov thiab muaj kev nyab xeeb nyob rau hauv qhov hnyav sab nraum zoov.
Lawv feem ntau yog siv los txuas DC - cov khoom siv sab hauv photovoltaic systems, tshwj xeeb suav nrog:
Series kev sib txuas ntawm modules
Kev sib txuas ntawm cov hlua thiab inverter
Kev sib txuas ntawm cov hlua thiab DC faib lub thawv (combiner thawv)
Kev sib txuas los ntawm DC faib lub thawv rau inverter. Cov kab hluav taws xob no yuav tsum raug cuam tshuam rau qhov chaw hnyav xws li kub kub, hluav taws xob ultraviolet, av noo, cua daj cua dub, thiab kub hloov pauv rau lub sijhawm ntev.
Yog li ntawd, lawv siv cov tin-plated oxygen-cov tooj liab dawb thiab irradiated cross- txuas polyolefin rwb thaiv tsev cov ntaub ntawv, muaj cov huab cua zoo heev, UV tsis kam, siab thiab kub tsis kam (-40℃txog 90℃lossis siab dua), thiab qis dua - pa taws halogen{7} tsis muaj flax.
Muab piv rau cov kab hluav taws xob zoo tib yam, photovoltaic DC cables muaj zog tiv thaiv qhov muaj peev xwm -induced degradation (PID) thiab cov rwb thaiv tsev siab dua tiv thaiv qhov ntsuas hluav taws xob (xws li DC 1100V lossis DC 1500V), txo qis cov kab poob, txhim kho lub zog tsim hluav taws xob, thiab ua kom muaj kev ua haujlwm ruaj khov rau ntau dua 25 xyoos.
Tsis tas li ntawd, lawv ob npaug - txheej txheej rwb thaiv tsev thiab xim coding (liab rau qhov zoo, dub rau qhov tsis zoo) txhim kho kev ruaj ntseg thiab kev saib xyuas yooj yim.
