Raws li lub ntiaj teb xav tau lub zog txuas ntxiv mus txuas ntxiv mus ntxiv, lub hnub ci hluav taws xob tau dhau los ua ib qho tseem ceeb tshaj plaws ntawm lub zog. Nyob rau hauv lub hnub ci photovoltaic (PV) cov tshuab, hnub ci clesles yog qhov kev sib kis muaj txiaj ntsig los ntawm kev nyab xeeb thiab kev sib kis hluav taws xob los ntawm cov panels hnub ci. Xaiv lub hnub ci tab sis tsuas yog txhim kho cov kev ua tau zoo ntawm cov kab ke, tab sis kuj ua kom muaj kev nyab xeeb thiab ntev ruaj khov ntawm lub system. Yog li, nkag siab txog cov yam ntxwv, kev thov thiab xaiv cov qauv ntawm ntau hom kev sib txawv ntawm cov hnub ci yog qhov tseem ceeb rau kev tsim thiab txhim kho hnub ci hauv hnub ci.
1. Dab tsi yog aHnub Ci Cable?
Hnub ci clesles yog cables tsim rauphotovoltaic (hnub ci photovoltaic) tshuabTxhawm rau xa hluav taws xob tsim los ntawm cov hnub ci ci los ntawm cov panels hnub qub rau cov khoom siv hluav taws xob, thiab tom qab ntawd mus rau lub zog cia khoom siv lossis cov phiaj xwm. Txij li hnub ci ntsa iab feem ntau tau nruab sab nraum zoov thiab yuav tsum tau nthuav tawm cov huab cua hnyav, UV tiv thaiv zoo, UV tsis kam thiab tshuaj lom neeg tiv taus. Tsis zoo li cov Cables dog dig, lub hnub ci cables yuav tsum tau ua raws cov qauv tshwj xeeb los ua haujlwm ntev ntawm cov kab ke.
2. Composition ntawm Hnub Ci Cables
Hnub ci cables feem ntau muaj cov ntu hauv qab no:
