Ib qho chaw ruaj khov thiab niaj hnub tsis yog tsuas yog nyob ntawm cov khoom siv hluav taws xob zoo thiab kev ua haujlwm zoo xwb, tab sis kuj yog nyob ntawm qhov zoo ntawm ob lub ntsiab lus tseem ceeb hauv cable: cov ntaub ntawv rwb thaiv tsev thiab cov ntaub qhwv.
Nyob rau hauv qhov tseeb zog tej yaam num, cables feem ntau raug rau hnyav ib puag ncig tej yam kev mob rau ncua sij hawm. Los ntawm kev raug UV ncaj qha, hluav taws xob hauv tsev, kev faus av hauv av, huab cua txias, mus rau nag hnyav, txhua yam teeb meem rau cov rwb thaiv tsev thiab cov ntaub ntawv sheath ntawm photovoltaic cables. Cov khoom siv feem ntau siv xws li cross-linked polyolefin (XLPO), cross-linked polyethylene (XLPE), thiab polyvinyl chloride (PVC). Txhua yam ntawm cov ntaub ntawv no muaj cov khoom sib txawv tsim nyog rau qhov sib txawv ib puag ncig thiab cov kev xav tau ntawm qhov project. Lawv tiv thaiv kom tsis txhob muaj zog thiab luv luv Circuit Court, thiab txo cov kev pheej hmoo xws li hluav taws kub lossis hluav taws xob poob siab.
PVC (Polyvinyl Chloride):
Vim nws qhov yooj yim, tus nqi nruab nrab, thiab kev yooj yim ntawm kev ua, PVC tseem yog ib qho khoom siv raw khoom siv rau cable rwb thaiv tsev thiab sheathing. Raws li cov khoom siv thermoplastic, PVC tuaj yeem yooj yim molded rau hauv ntau yam duab. Nyob rau hauv cov tshuab photovoltaic, nws feem ntau xaiv los ua cov khoom siv sheath, muab kev tiv thaiv kev puas tsuaj rau cov neeg ua haujlwm sab hauv thaum pab txo cov peev nyiaj tag nrho.
XLPE (Cross-linked Polyethylene):
Ua los ntawm cov txheej txheem silane hla kev sib txuas, silane coupling cov neeg ua haujlwm tau nkag mus rau hauv polyethylene los txhim kho lub zog thiab kev laus. Thaum siv rau cov cables, cov qauv molecular no ua rau cov neeg kho tshuab muaj zog thiab ruaj khov, ua kom muaj zog nyob rau hauv huab cua huab cua.
XLPO (Cross-linked Polyolefin):
Ua los ntawm cov txheej txheem tshwj xeeb irradiation cross-linking txheej txheem, linear polymers tau hloov mus rau hauv cov khoom siv ua haujlwm siab nrog cov qauv peb sab. Nws muaj kev tiv thaiv UV zoo, tiv thaiv thermal, tiv thaiv txias, thiab cov khoom siv kho tshuab. Nrog kev yooj yim dua thiab huab cua tsis kam tshaj XLPE, nws yooj yim rau nruab thiab ua haujlwm hauv cov txheej txheem nyuaj - ua rau nws tsim tshwj xeeb rau lub hnub ci vaj huam sib luag lossis hauv av-mounted array systems.
Peb cov XLPO compound rau photovoltaic cables ua raws li RoHS, REACH, thiab lwm yam thoob ntiaj teb cov qauv. Nws ua tau raws li qhov yuav tsum tau ua ntawm EN 50618: 2014, TÜV 2PfG 1169, thiab IEC 62930: 2017, thiab tsim nyog siv rau hauv rwb thaiv tsev thiab sheath txheej ntawm photovoltaic cables. Cov khoom siv ua kom muaj kev nyab xeeb ib puag ncig thaum muab kev ua haujlwm zoo heev thiab du extrusion nto, txhim kho cable manufacturing efficiency thiab cov khoom sib xws.
Hluav taws kub & Dej tsis kam
XLPO, tom qab irradiation cross-linking, muaj cov khoom siv hluav taws xob hauv hluav taws xob. Nws tswj kev ruaj ntseg nyob rau hauv qhov kub thiab txias, txo qhov hluav taws kub. Nws kuj tseem txhawb nqa AD8-rated dej tsis kam, ua rau nws haum rau qhov chaw ntub dej lossis los nag. Hauv qhov sib piv, XLPE tsis muaj cov nplaim hluav taws kub nyhiab thiab zoo dua rau cov tshuab uas xav tau cov dej tsis muaj zog. Thaum PVC muaj peev xwm tua tus kheej, nws cov combustion yuav tso tawm ntau cov pa roj.
Toxicity & Environmental Impact
XLPO thiab XLPE yog ob qho tib si halogen-dawb, tsis muaj pa luam yeeb cov ntaub ntawv uas tsis tso cov roj chlorine, dioxins, los yog corrosive acid pos huab thaum combustion, muab ntau dua ib puag ncig tus phooj ywg. PVC, ntawm qhov tod tes, tuaj yeem tso cov pa phem rau tib neeg thiab ib puag ncig ntawm qhov kub thiab txias. Tsis tas li ntawd, qhov siab ntawm kev sib txuas ntawm XLPO muab nws lub neej kev pabcuam ntev dua, pab txo cov nqi hloov mus ntev thiab kev saib xyuas.
XLPO & XLPE
Daim ntawv thov Scenarios: Loj-scale hnub ci fais fab nroj tsuag nyob rau hauv cheeb tsam uas muaj zog tshav ntuj los yog hnyav huab cua, coj mus muag thiab muaj hnub ci rooftops, hauv av-mounted hnub ci arrays, underground corrosion-resistant tej yaam num.
Lawv qhov yooj yim txhawb nqa cov txheej txheem nyuaj, vim tias cov cables yuav tsum tau taug qab cov teeb meem lossis kev hloov kho tsis tu ncua thaum lub sijhawm teeb tsa. XLPO qhov ua tau zoo nyob rau hauv huab cua huab cua ua rau nws muaj kev ntseeg siab rau cov cheeb tsam uas muaj qhov kub thiab txias thiab ib puag ncig hnyav. Tshwj xeeb tshaj yog nyob rau hauv cov haujlwm photovoltaic nrog kev xav tau siab rau cov nplaim hluav taws xob, kev tiv thaiv ib puag ncig, thiab kev ua haujlwm ntev, XLPO sawv tawm raws li cov khoom nyiam.
PVC
Daim ntawv thov Scenarios: Sab hauv tsev hnub ci teeb, ntxoov ntxoo lub hnub ci ntsa iab, thiab tej yaam num nyob rau hauv temperate climates nrog tsawg tshav ntuj raug.
Txawm hais tias PVC muaj qis dua UV thiab kub tsis kam, nws ua tau zoo nyob rau hauv ib puag ncig raug pom (xws li cov tshuab sab hauv tsev lossis ib nrab ntxoov ntxoo sab nraum zoov) thiab muaj kev xaiv nyiaj txiag.
