Lub hnub ci zog tau dhau los ua qhov tseem ceeb ntawm lub zog tauj dua tshiab hauv xyoo tas los no vim nws txoj kev ruaj khov thiab txo cov nqi installation. Ib qho tseem ceeb ntawm txhua lub hnub ci zog yog qhovphotovoltaic (PV) cable,uas ua kom muaj kev sib kis tau zoo ntawm cov hluav taws xob uas tsim los ntawm cov hnub ci vaj huam sib luag rau inverters thiab lwm yam khoom siv. Txawm li cas los xij, cov cables no yuav tsum tau tsim los tiv thaiv ntau yam kev mob ib puag ncig, suav nrog cov av noo ib puag ncig, qhov twg yam xws li ya raws thiab condensation tuaj yeem cuam tshuam tsis zoo rau lawv cov kev ua tau zoo thiab kav ntev. Tsab ntawv xov xwm no yuav tshawb txog qhov tsim nyog ntawm cov hnub ci cables rau qhov chaw muaj av noo, nthuav dav cov ntaub ntawv, kev tsim kho, thiab kev txiav txim siab uas ua rau cov kab hluav taws xob photovoltaic zoo tagnrho rau cov xwm txheej zoo li no.
Dab tsi yog Solar Cable?
Lub hnub ci cable, tseem hu ua photovoltaic cable, yog ib hom hluav taws xob xaim tshwj xeeb tsim los siv rau hauv lub hnub ci zog. Hnub ci cables yog siv los txuas cov hnub ci vaj huam sib luag rau cov inverters, roj teeb, thiab lwm yam khoom ntawm lub hnub ci zog. Cov cables no yuav tsum ua kom tau raws li cov kev xav tau tshwj xeeb, vim lawv raug rau qhov chaw sab nraum zoov, huab cua hnyav, thiab hluav taws xob UV. Cov kab hluav taws xob hnub ci yog tsim los tswj cov hluav taws xob xav tau ntawm lub hnub ci thiab cov xwm txheej ib puag ncig lawv ntsib.
Cov yam ntxwv tseem ceeb uas teeb lub hnub ci cables sib nrug los ntawm cov kab hluav taws xob ib txwm muaj xws li:
UV tsis kam: Hnub ci cables yog tsim los tiv thaiv UV degradation los ntawm kev raug tshav ntuj ntev.
Huab cua tsis zoo: Lawv tuaj yeem tiv taus nag, daus, thiab kub heev.
Hluav taws kub: Cov kab hluav taws xob hnub ci yog tsim los txo qhov kev pheej hmoo ntawm hluav taws kub.
Durability: Hnub ci cables yog tsim los kav ntev ntau xyoo yam tsis muaj degradation.
Ntsiab nta ntawmHnub ci Cables
1. Khoom siv
Cov ntaub ntawv siv ntau tshaj plaws siv rau kev tsim hluav taws xob hnub ci muaj xws li tooj liab conductors thiab cov ntaub ntawv rwb thaiv tsev xws li thermoplastic elastomers (TPE) lossis cross-linked polyethylene (XLPE). Tooj liab yog cov khoom siv hluav taws xob zoo heev thiab muaj zog heev, thaum TPE thiab XLPE cov ntaub ntawv muaj kev tiv thaiv kub kub, UV hluav taws xob, thiab cov khoom ib puag ncig.
Cov txheej txheej rwb thaiv tsev yog qhov tseem ceeb tshwj xeeb hauv qhov chaw muaj av noo, vim nws yuav tsum tiv thaiv kom tsis txhob ya raws los ntawm kev nkag mus rau hauv lub hauv paus ntawm lub cable. Qhov no pab tiv thaiv kev pheej hmoo ntawm luv luv Circuit Court, corrosion, thiab txo kev ua haujlwm.
2. UV thiab huab cua Resistance
Cov kab hluav taws xob hnub ci yog tsim los tiv thaiv lub hnub qhov teeb meem ultraviolet (UV) hluav taws xob, uas tuaj yeem ua rau cov ntaub ntawv degrade thiab tawg thaum lub sijhawm. High-zoo photovoltaic cables yog insulated nrog UV-resistant cov ntaub ntawv, kom ntseeg tau ntev kev kawm nyob rau hauv sab nraum zoov ib puag ncig. Tsis tas li ntawd, cov cables no tau tsim los tswj ntau yam huab cua, xws li nag, daus, thiab huab cua txias, ua rau lawv tsim nyog rau kev teeb tsa hauv thaj chaw uas muaj av noo siab.
3. Waterproofing
Nyob rau hauv ib puag ncig high-humidity, nws yog ib qho tseem ceeb uas lub hnub ci cables yog waterproof los yog tsawg kawg yog heev tiv taus dej nkag. Cov dej noo tuaj yeem ua rau cov khoom siv rwb thaiv tsev tawg, ua rau luv luv, hluav taws xob poob, thiab txawm tias hluav taws kub hnyiab. Txhawm rau tiv thaiv qhov no, cov khoom siv hluav taws xob zoo hnub ci tau tsim los nrog kev sib khi ntxiv thiab cov dej noo-tiv taus kom ntseeg tau tias cov cables tuaj yeem tiv taus dej ntev.
4. Hluav taws kub tsis kam
Txij li cov kab hluav taws xob hnub ci tuaj yeem raug cuam tshuam rau ntau yam ib puag ncig xws li cua sov, xob laim, thiab sparks, lawv yuav tsum yog hluav taws-resistant. Feem ntau cov kab hluav taws xob photovoltaic yog tsim los nrog cov hluav taws kub tiv thaiv sab nraud uas tiv thaiv kev sib kis ntawm cov nplaim taws thaum muaj hluav taws xob tsis raug lossis hluav taws xob.
Solar Cables thiab High-Humidity Ib puag ncig
High-humidity ib puag ncig muaj ntau yam teeb meem rau cov tshuab hluav taws xob, tshwj xeeb tshaj yog cov uas raug rau sab nraum zoov. Nyob rau hauv cov xwm txheej no, noo noo thiab condensation tuaj yeem sib sau rau ntawm qhov chaw, ua rau muaj kev pheej hmoo ntawm corrosion, luv Circuit Court, thiab degradation ntawm cov kab hluav taws xob rwb thaiv tsev. Txawm li cas los xij, cov kab hluav taws xob hnub ci tau tsim tshwj xeeb los txo cov kev pheej hmoo no thiab muab kev ua tau zoo hauv cov cheeb tsam zoo li no.
1. Tiv thaiv Corrosion
Cov conductors nyob rau hauv lub hnub ci cables, feem ntau yog ua los ntawm tooj liab los yog tinned tooj liab, yog heev resistant rau corrosion. Txawm li cas los xij, nyob rau hauv cov cheeb tsam uas muaj cov av noo siab, qhov ntev ntev ntawm cov av noo tuaj yeem ua rau oxidation ntawm cov khoom siv hlau, uas tuaj yeem txo cov kev ua haujlwm ntawm cov cable los yog ua rau hluav taws xob tsis zoo. Txhawm rau tiv thaiv qhov no, cov tuam txhab siv cov txheej txheem thiab cov ntaub ntawv insulating uas tiv thaiv corrosion, xws li cross-linked polyethylene (XLPE) los yog thermoplastic elastomers (TPE), uas tiv thaiv cov dej noo los ntawm kev nkag mus rau hauv cable thiab ncav cuag cov hlau conductors.
2. Waterproof thiab Moisture-Resistant rwb thaiv tsev
Cov kab hluav taws xob hnub ci tsim los rau cov av noo ib puag ncig feem ntau muaj cov txheej txheem tshwj xeeb uas tsis muaj dej tsis zoo lossis tsis muaj dej. Cov txheej no tiv thaiv dej los ntawm kev nkag mus rau hauv lub cable, uas tuaj yeem ua rau cov khoom siv hluav taws xob puas. Cov ntaub ntawv rwb thaiv tsev siv hauv cov cables no tau tsim tshwj xeeb los tiv thaiv kev nqus dej, kom ntseeg tau tias cov cables ua tau zoo txawm tias nyob hauv nag lossis ntub dej.
3. Kub stability
Nyob rau hauv ib puag ncig high-humidity, qhov kub thiab txias hloov pauv tau tshwm sim, thiab lawv tuaj yeem ua rau muaj kev cuam tshuam ntawm cov dej noo. Cov kab hluav taws xob hnub ci yuav tsum muaj peev xwm tiv taus cov kev hloov pauv no thiab txuas ntxiv ua haujlwm ruaj khov. Cov kab hluav taws xob photovoltaic zoo yog tsim los ntawm cov khoom siv kub-ruaj khov uas tswj lawv qhov yooj yim thiab lub zog nyob rau hauv ntau qhov kub thiab txias, nrog rau cov cheeb tsam uas muaj cua sov lossis txias. Qhov no ua kom ntseeg tau tias cov cables yuav tsis tawg lossis poob lawv cov txiaj ntsig vim thermal expansion lossis contraction, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm cov dej noo.
4. Pwm thiab Fungal Resistance
Cov av noo siab kuj tuaj yeem txhawb kev loj hlob ntawm cov pwm thiab cov kab mob, uas tuaj yeem ua rau cov kab hluav taws xob sab nraud puas tsuaj. Txhawm rau hais txog qhov no, lub hnub ci cables npaj rau siv nyob rau hauv qhov chaw muaj av noo feem ntau raug kho nrog cov tshuaj tua kab mob los yog tsim los nrog cov ntaub ntawv uas tiv thaiv kev loj hlob ntawm cov pwm lossis cov kab mob. Qhov no pab tswj kev ncaj ncees ntawm cov cables thiab xyuas kom lawv nyob nyab xeeb thiab ua haujlwm tau zoo nyob rau lub sijhawm.
5. Environmental Certification
Cov kab hluav taws xob hnub ci npaj rau qhov chaw muaj av noo feem ntau raug kuaj nruj thiab muaj ntawv pov thawj kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog rau kev nyab xeeb thiab kav ntev. Piv txwv li, ntau lub xov tooj hluav taws xob photovoltaic raug kuaj raws li International Electrotechnical Commission (IEC) 60216 tus qauv, uas ntsuas cov kab hluav taws xob muaj peev xwm tiv taus kub, av noo, thiab UV raug. Cables uas dhau qhov kev ntsuam xyuas no tau ntawv pov thawj rau siv nyob rau hauv ntau yam ib puag ncig tej yam kev mob, nrog rau high humidity chaw.
