Kev txiav txim siab txog UV tiv thaiv ntawm lub xov tooj hluav taws xob photovoltaic tuaj yeem ua tiav los ntawm kev ntsuam xyuas dav dav ntawm plaub yam: cov khoom siv, cov qauv ntawv pov thawj, cov ntaub ntawv kuaj kev laus, thiab cov yam ntxwv zoo li.
1. Txheeb xyuas cov khoom siv thiab cov qauv tsim
Cov ntaub ntawv rwb thaiv tsev thiab cov ntaub thaiv npog: Ua ntej cov cables siv irradiated cross -linked polyolefin (XLPO) lossis cross-linked polyethylene (XLPE). Cov ntaub ntawv no tsim ib qho peb - qhov sib txuas network qauv los ntawm electron beam cross- txuas, txhim kho UV tiv thaiv.
Additive Formulation: High -zoo photovoltaic cables muaj carbon dub (2%-3%), UV absorbers (xws li benzotriazoles), thiab lub teeb stabilizers (xws li hindered amines zoo li HALS), zoo absorbing los yog reflecting UV rays thiab tiv thaiv polymer chain breakage.
Ob chav Sheath Design: Qee cov khoom siab- kawg siv cov txheej txheej sab nraud ntawm siab- huab cua- tiv taus polyolefin thiab cov nplaim hluav taws sab hauv- cov khoom siv retardant, ntxiv dag zog rau UV tiv thaiv.
2. Txheeb xyuas cov ntawv pov thawj thoob ntiaj teb thiab cov qauv
Cables ua raws li cov ntaub ntawv pov thawj hauv qab no tau dhau los kuaj UV tsis kam:
TÜV 2Pfg 1169: Yuav tsum tau 1008 teev ntawm UV irradiation ntawm 340nm wavelength thiab 0.71W / m² siv (simulating kwv yees li 10 xyoo ntawm sab nraum zoov raug) ntawm 70 degree, tsis muaj sheath tawg thiab ib tug neeg kho tshuab tuav tus nqi siab tshaj 8%.
TS EN 50618 / UL 4703: Cov qauv tseem ceeb hauv North American thiab European kev lag luam, suav nrog kev kuaj xyuas kev laus kom nrawm dua UV.
IEC 62930: Tus qauv thoob ntiaj teb tshwj xeeb rau cov kab hluav taws xob photovoltaic, qhia meej meej cov ntsuas huab cua tiv thaiv.
3. Xa mus rau Accelerated Aging Test Results
Los ntawm cov cuab yeej tshaj lij uas simulating ntev - lub sij hawm raug, cov ntaub ntawv tseem ceeb suav nrog:
Xenon Arc Lamp Aging Test: 2000 teev ntawm kev siv hluav taws xob tas li ntawm 550W / m² siv, tensile lub zog tuav tus nqi siab dua lossis sib npaug li 85%, elongation ntawm tawg Ntau dua lossis sib npaug li 70%. Qhov tseeb sab nraum zoov pov thawj: Tom qab 10 xyoo ntawm kev siv nyob rau hauv siab -UV ib puag ncig xws li cov suab puam Sahara, lub sheath tsis muaj cov kab nrib pleb los yog hmoov, thiab cov rwb thaiv tsev kuj tseem nyob saum 95%.
Thermo-oxidative aging + UV synergistic test: Tom qab 135℃× 168h ntawm thermo-aging, UV irradiation tau siv los ntsuas cov khoom siv huab cua tag nrho.
