Kukhazikika kokhazikika komanso kofananako sikudalira kokha pamapangidwe apamwamba a conductor ndi magwiridwe antchito, komanso pamtundu wa zigawo ziwiri zazikuluzikulu mu chingwe: zotchingira ndi sheath zida.
M'mapulojekiti enieni amagetsi, zingwe nthawi zambiri zimakumana ndi zovuta zachilengedwe kwa nthawi yayitali. Kuchokera pakuwonekera mwachindunji kwa UV, moto womanga, kuyikidwa mmanda mobisa, kuzizira kwambiri, mpaka mvula yamkuntho, zonse zimabweretsa zovuta pakutchingira ndi zida za sheath za zingwe za photovoltaic. Zomwe zimagwiritsidwa ntchito kwambiri ndi polyolefin (XLPO), cross-linked polyethylene (XLPE), ndi polyvinyl chloride (PVC). Chilichonse mwazinthu izi chili ndi katundu wosiyana woyenera kusiyanasiyana kwa chilengedwe komanso zofunikira za polojekiti. Amateteza bwino kutayika kwa mphamvu ndi mabwalo amfupi, ndikuchepetsa zoopsa monga moto kapena kugwedezeka kwamagetsi.
PVC (Polyvinyl Chloride):
Chifukwa cha kusinthasintha kwake, mtengo wocheperako, komanso kumasuka kwa kukonza, PVC imakhalabe chinthu chomwe chimagwiritsidwa ntchito kwambiri pakutchinjiriza chingwe ndi sheathing. Monga zida za thermoplastic, PVC imatha kupangidwa mosavuta mumitundu yosiyanasiyana. Mu machitidwe a photovoltaic, nthawi zambiri amasankhidwa ngati katundu wa sheath, kupereka chitetezo cha abrasion kwa otsogolera amkati pamene akuthandizira kuchepetsa bajeti yonse ya polojekiti.
XLPE (Polyethylene Yophatikizika):
Amapangidwa pogwiritsa ntchito njira yolumikizira silane yolumikizira, ma silane amalowetsedwa mu polyethylene kuti alimbikitse mphamvu komanso kukana kukalamba. Ikagwiritsidwa ntchito pazingwe, mawonekedwe a mamolekyuwa amathandizira kwambiri mphamvu zamakina ndi kukhazikika, kuonetsetsa kulimba pansi pa nyengo yoipa.
XLPO (Polyolefin Yophatikizika):
Opangidwa kudzera mu njira yapadera yolumikizira yolumikizana ndi kuwala, ma polima amzere amasinthidwa kukhala ma polima apamwamba kwambiri okhala ndi maukonde atatu azithunzi. Imapereka kukana kwa UV bwino, kukana kutentha, kukana kuzizira, komanso makina. Ndi kusinthasintha kwakukulu komanso kukana kwa nyengo kuposa XLPE, ndikosavuta kuyika ndikuwongolera m'masanjidwe ovuta - kupangitsa kuti ikhale yoyenera kwambiri pama sola adzuwa padenga kapena makina oyambira pansi.
Gulu lathu la XLPO la zingwe za photovoltaic limagwirizana ndi RoHS, REACH, ndi miyezo ina yapadziko lonse lapansi. Imakwaniritsa zofunikira za EN 50618: 2014, TÜV 2PfG 1169, ndi IEC 62930: 2017, ndipo ndiyoyenera kugwiritsidwa ntchito pomanga ndi zigawo za sheath za zingwe za photovoltaic. Zinthuzi zimatsimikizira chitetezo cha chilengedwe pomwe zikupereka kuyendetsa bwino kwambiri komanso kutulutsa kosalala, kuwongolera magwiridwe antchito a chingwe komanso kusasinthika kwazinthu.
Kulimbana ndi Moto ndi Madzi
XLPO, itatha kulumikizana ndi waya, imakhala ndi zinthu zoletsa moto. Imasunga bata pansi pa kutentha kwakukulu ndi kupanikizika, kuchepetsa kwambiri chiopsezo cha moto. Imathandiziranso kukana kwamadzi kwa AD8, ndikupangitsa kuti ikhale yoyenera malo amvula kapena mvula. Mosiyana ndi izi, XLPE ilibe kuchedwa kwamoto ndipo ndi yoyenera pamakina omwe amafunikira kukana madzi mwamphamvu. Ngakhale kuti PVC ili ndi mphamvu yozimitsa yokha, kuyaka kwake kungathe kutulutsa mpweya wovuta kwambiri.
Toxicity & Environmental Impact
XLPO ndi XLPE onse ndi zinthu zopanda halogen, zosuta pang'ono zomwe sizitulutsa mpweya wa klorini, ma dioxin, kapena nkhungu ya corrosive acid pa kuyaka, zomwe zimapatsa chidwi kwambiri ndi chilengedwe. Komano, PVC imatha kutulutsa mpweya woipa kwa anthu ndi chilengedwe pa kutentha kwakukulu. Kuphatikiza apo, kuchuluka kwa kulumikizana pakati pa XLPO kumapangitsa kuti ikhale ndi moyo wautali wautumiki, zomwe zimathandiza kuchepetsa ndalama zosinthira ndi kukonza kwanthawi yayitali.
XLPO & XLPE
Mmene Mungagwiritsire Ntchito: Zopangira magetsi adzuwa zazikulu m'zigawo zokhala ndi kuwala kwadzuwa kapena nyengo yoyipa, denga ladzuwa lamalonda ndi mafakitale, zida zopangira mphamvu yadzuwa zokhazikika pansi, mapulojekiti osagwirizana ndi dzimbiri.
Kusinthasintha kwawo kumathandizira masanjidwe ovuta, chifukwa zingwe zimafunika kuyendetsa zopinga kapena kusinthidwa pafupipafupi pakuyika. Kukhazikika kwa XLPO nyengo yotentha kumapangitsa kukhala chisankho chodalirika kumadera omwe ali ndi kusinthasintha kwa kutentha komanso malo ovuta. Makamaka m'mapulojekiti a photovoltaic omwe amafunidwa kwambiri chifukwa cha kuwonongeka kwa malawi, kuteteza chilengedwe, ndi moyo wautali, XLPO imadziwika kuti ndi chinthu chomwe chimakonda kwambiri.
Zithunzi za PVC
Mmene Mungagwiritsire Ntchito: Kuyika kwa dzuwa m'nyumba, makina oyendera dzuwa omwe ali padenga, ndi mapulojekiti omwe ali m'malo ofunda komanso osayatsidwa ndi dzuwa.
Ngakhale PVC ili ndi UV yotsika komanso kukana kutentha, imachita bwino m'malo osawoneka bwino (monga makina am'nyumba kapena makina akunja amdima pang'ono) ndipo imapereka njira yabwino bajeti.
