Hauv lub ntiaj teb ntawm lub zog txuas ntxiv dua, PV) ua si ib lub luag haujlwm tseem ceeb hauv kev ua kom muaj hluav taws xob. Pheebsoltaic Cables, tseem yog hnub ci hluav taws xob, yog qhov tseem ceeb ntawm lub zog hluav taws xob tsim hluav taws xob thiab, thaum kawg, rau cov hluav taws xob lossis cov roj teeb cia. Cov cable tshwj xeeb no yog tsim los tiv thaiv cov mob hnyav, kom muaj kev nyab xeeb thiab tshuaj tiv thaiv hluav taws xob muaj kev nyab xeeb rau lub sijhawm ntev.
Hauv tsab xov xwm no, peb yuav dhia mus tob rau hauv lub photovoltaic cables yog, lawv ua haujlwm li cas, lawv qhov tseem ceeb hauv hnub ci zog, thiab cov sib txawv ntawm lub hnub ci cables muaj. Peb tseem yuav tshawb cov qauv thiab cov kev tswj uas kav lub hnub ci hluav taws xob kom ntseeg tau tias lawv txoj kev nyab xeeb thiab kav ntev.
1. Dab tsi yog aPhotovoltaic cable?
Lub photovoltaic cable yog hom xaim hluav taws xob uas tau tsim tshwj xeeb los siv hauv photovoltaic (hnub ci). Cov xaim no yog lub luag haujlwm rau kev sib txuas covHnub ci Panelsrau lwm qhov system Cheebtsam, xws li Inverters, roj teeb, thiab cov hluav taws xob hluav taws xob. Hnub ci cables yuav tsum ua raws li cov txheej txheem tshwj xeeb los xyuas kom lawv tuaj yeem tiv thaiv qhov kev xav tau ntawm cov mob sab nraum zoov, suav nrog qhov kev xav tau ntawm sab nraum zoov qhov kev xav tau ntawm sab nraum zoov qhov kev xav tau ntawm sab nraum zoov qhov kev xav tau ntawm sab nraum zoov chaw, kev kub ntxhov, noo noo, thiab kev ntxhov siab ntau yam, thiab kev ntxhov siab ntau, thiab kev ntxhov siab ntau yam, thiab kev ntxhov siab ntau yam, noo noo.
Cov xov tooj pheeb suab feem ntau yog ua los ntawm tooj liab lossis txhuas cov neeg uas muaj cov ntaub ntawv tiv thaiv ib puag ncig. Cov rwb thaiv tsev thiab cov ntaub ntawv sheathing yog tsim los tiv thaiv tshav kub, noo noo, alliocture, kom txhua yam kev puas tsuaj, kom ua tau zoo nyob rau lub sijhawm ntev.
2. Cov yam ntxwv tseem ceeb ntawm photovoltaic cables
2.1 Hluav Taws Xob Kev Tshaj Tawm
Lub luag haujlwm tseem ceeb ntawm lub hnub ci hlau yog los hloov hluav taws xob. Yog li ntawd, cov cables yuav tsum muaj hluav taws xob zoo kom txo kev poob zog. Feem ntau cov photovoltaic Cables siv tooj liab lub npees vim tias tooj liab muaj cov hluav taws xob zoo dua piv rau lwm cov hlau zoo li txhuas. Qhov no yog qhov tshwj xeeb hauv nruab hnub ci loj uas muaj zog poob yog qhov tseem ceeb rau kev ua kom loj hlob.
2.2 Rwb thaiv tsev thiab cov ntaub ntawv
Txhawm rau tiv thaiv tus neeg saib xyuas thiab xyuas kom muaj kev nyab xeeb ntawm hluav taws xob, hnub ci cables yog nruab nrog rwb thaiv tsev thiab ib rab riam sab nraud. Cov rwb thaiv tsev yog ib txwm ua los ntawm cov ntaub ntawv xws li:
Hla-Txuas Polyethylene (XLPE): Cov khoom siv no muab siab tiv taus cua sov, UV hluav taws xob, thiab tshuaj lom neeg raug. Nws yog feem ntau siv nyob rau hauv photovoltaic cables vim tias nws cov kev ua tau zoo nyob rau hauv cov xwm txheej phem hauv kev ua haujlwm.
Thermoplastic elastomer (TPE): TPE yog lwm cov khoom siv rwb thaiv tsev siv rau cov xov hlau hluav taws xob vim nws txoj kev hloov pauv, noo noo, thiab cov kev hloov pauv thiab kub thiab qhov kub.
Polyvinyl chloride (PVC): PVC feem ntau siv rau sab hauv lub hnub ci nplhaib tab sis tsis tshua muaj tshwm sim hauv kev siv hluav taws xob sab nraum zoov thiab kev ua kom muaj kev cuam tshuam.
Cov kab hluav taws xob sab nraud yog tsim los muab kev tiv thaiv ntxiv los ntawm kev puas tsuaj hluav taws xob, UV hluav taws xob, thiab noo noo. Cov yeeb yaj kiab no feem ntau yog ua los ntawm UV-resistant cov ntaub ntawv uas xyuas kom cov cables nyob ruaj khov txawm tias raug ua lub hnub ncaj qha rau ncua sijhawm.
