Tus tsim lifespan ntawm photovoltaic DC cables yog feem ntau tshaj 25 xyoo, txuam lub voj voog khiav hauj lwm ntawm lub chaw nres tsheb photovoltaic. Raws li cov txheej txheem kev khiav hauj lwm thiab nrog siab - cov ntaub ntawv zoo thiab cov txheej txheem tsim khoom, qee cov khoom ua tau zoo - tuaj yeem ncav cuag lub neej ntawm 50 xyoo.
1. Kev lag luam Standard Lifespan: 25 Xyoo
Photovoltaic DC cables tshwj xeeb yog tsim los rau lub hnub ci zog thiab yuav tsum raug rau qhov chaw sab nraum zoov hnyav rau lub sijhawm ntev. Lawv lub hom phiaj lifespan yog raws li cov photovoltaic modules, feem ntau tsim rau 25 xyoo.
Cov qauv tseem ceeb, xws li PV1-F cables, tau dhau daim ntawv pov thawj thoob ntiaj teb xws li TÜV 2PfG 1169/08.2007, uas qhia meej meej yuav tsum tau ua haujlwm ruaj khov rau 25 xyoo nyob rau hauv ib puag ncig uas muaj hluav taws xob ultraviolet, qhov kub thiab txias (-40℃rau +90 degree), thiab cov cua sov.
Cov cables siv irradiated cross-txuas polyolefin cov ntaub ntawv raws li rwb thaiv tsev thiab sheathing. Tom qab electron beam irradiation, ib qho peb - qhov sib txuas network qauv tsim, ua kom muaj zog tiv thaiv tshav kub, tiv thaiv kev laus, thiab lub zog txhua yam.
2. Cov khoom siv thiab cov txheej txheem ua kom lub neej ua haujlwm ntev
Tus neeg xyuas pib: High-purity tin-plated tooj liab lossis aluminium alloy yog siv los txhim kho oxidation kuj thiab conductivity stability.
Rwb thaiv tsev thiab Sheath: Hla-txuas polyethylene (XLPE) los yog qis- pa taws halogen-dawb nplaim hluav taws- polyolefin retardant yog siv, muaj huab cua tiv thaiv zoo, nplaim taws retardancy, thiab kev ua haujlwm ib puag ncig.
Tshwj xeeb Additives: UV absorbers thiab lub teeb stabilizers yog ntxiv rau cov mis kom zoo tiv thaiv kev laus thiab tawg los ntawm lub sij hawm ntev - raug tshav ntuj.
