Lub neej ntev ntawm PV DC cable yog feem ntau tshaj 25 xyoo, sib piv cov qauv tsim thiab kev ua haujlwm ntawm lub chaw nres tsheb PV. Nyob rau hauv cov xwm txheej ntawm siab - cov ntaub ntawv zoo thiab cov qauv kev teeb tsa, qee cov khoom ua tau zoo - tuaj yeem ncav cuag 50 xyoo.
1. Tus qauv tsim Lifespan: 25 Xyoo
PV DC cables tshwj xeeb yog tsim los rau ntev - siv sab nraum zoov thiab yuav tsum tiv taus qhov chaw hnyav xws li hluav taws xob ultraviolet, qhov kub thiab txias sib txawv (-40℃rau +120 degree), av noo, thiab ntsev tsuag.
Cov qauv kev lag luam tseem ceeb xws li TÜV 2PfG 1169/08.07 thiab IEC 62930 kom meej meej xav kom cov cables ua haujlwm ruaj khov rau tsawg kawg 25 xyoo thoob plaws hauv lawv lub neej.
Cov qauv xws li PV1-F thiab H1Z2Z2-K yog tsim los nrog 25- xyoo kev ua neej raws li qhov ntsuas. Lawv cov rwb thaiv tsev thiab sheath siv hluav taws xob-crosslinked halogen-dawb, tsis muaj pa taws, nplaim hluav taws-retardant polyolefin cov ntaub ntawv, thiab lawv cov kev ntseeg tau raug txheeb xyuas los ntawm kev ntsuam xyuas kev laus sai.
2. Cov khoom siv thiab cov txheej txheem tsim khoom txiav txim siab ntev
Conductors: Feem ntau tin-plated tooj liab hlau los yog txhuas alloy, txhim khu oxidation kuj thiab conductivity stability.
Rwb thaiv tsev thiab Sheath: Ib qho peb- qhov sib txuas network qauv yog tsim los ntawm electron beam irradiation cross-kev sib txuas tshuab, ua kom muaj zog tiv thaiv tshav kub, tiv thaiv kev laus, thiab lub zog txhua yam.
Ntxiv cov UV absorbers, antioxidants, nplaim hluav taws, thiab lwm yam additives zoo ncua kev laus thiab tawg los ntawm lub sij hawm ntev - raug tshav ntuj.
4. Tej yam tseem ceeb cuam tshuam rau lub neej tiag tiag
Environmental Stress: Kub kub, muaj zog ultraviolet hluav taws xob, thiab ntug hiav txwv ntsev tsuag ua kom cov khoom laus.
Kev Txhim Kho Zoo: Tsis txaus khoov lub vojvoog, kev sib tw ntau dhau, thiab kev sib koom ua ke tsis zoo yooj yim ua rau ua tsis tiav thaum ntxov.
Kev Ua Haujlwm thiab Kev Pabcuam: Ntev- lub sijhawm dhau thiab tsis muaj kev ntsuas rwb thaiv tsev ua rau lub neej ua haujlwm luv luv.
