I-XLPO vs XLPE vs PVC: Izinzuzo Zokusebenza kanye Nezimo Zokusebenza Kuzintambo Ze-Photovoltaic

I-current eqinile nefanayo ayincikile kuphela ezakhiweni ze-conductor ezisezingeni eliphezulu nokusebenza, kodwa futhi nasezingeni lezingxenye ezimbili ezibalulekile kukhebula: i-insulation ne-sheath materials.

Kumaphrojekthi wangempela wamandla, izintambo zivame ukuchayeka ezimeni zemvelo ezinzima isikhathi eside. Kusukela ekuchayekeni okuqondile kwe-UV, imililo yokwakha, ukungcwaba ngaphansi komhlaba, amakhaza amakhulu, kuya emvuleni enamandla, konke kubeka izinselele ekwakhiweni kwe-insulation kanye ne-sheath yezintambo ze-photovoltaic. Izinto ezisetshenziswa kakhulu ezisetshenziswayo zifaka i-polyolefin (XLPO), i-cross-linked polyethylene (XLPE), ne-polyvinyl chloride (PVC). Ngayinye yalezi zinto inezakhiwo ezihlukile ezifanele izimo zemvelo ezahlukene kanye nezidingo zephrojekthi. Zivikela ngempumelelo ukulahleka kwamandla namasekhethi amafushane, futhi zinciphise izingozi ezinjengomlilo noma ukushaqeka kukagesi.

I-PVC (i-Polyvinyl Chloride):
Ngenxa yokuguquguquka kwayo, intengo emaphakathi, kanye nokucutshungulwa kalula, i-PVC isalokhu iyimpahla eluhlaza esetshenziswa kakhulu yokufaka ikhebula nokushelela. Njengempahla ye-thermoplastic, i-PVC ingabunjwa kalula ibe yizimo ezihlukahlukene. Ezinhlelweni ze-photovoltaic, kuvame ukukhethwa njengento ye-sheath, enikeza ukuvikelwa kokuhuzuka kwabaqhubi bangaphakathi ngenkathi kusiza ukunciphisa isabelomali sephrojekthi jikelele.

I-XLPE (I-Polyethylene Exhunywe Ngokuphambene):
Ikhiqizwe kusetshenziswa inqubo yokuxhumanisa i-silane yobungcweti, ama-ejenti okuhlanganisa ama-silane afakwa ku-polyethylene ukuze kuthuthukiswe amandla nokumelana nokuguga. Uma isetshenziswa ezintanjeni, lesi sakhiwo samangqamuzana sithuthukisa kakhulu amandla emishini nokuzinza, siqinisekisa ukuqina ngaphansi kwezimo zezulu ezimbi kakhulu.

I-XLPO (I-Polyolefin Exhunywe Ngokuphambanayo):
Akhiqizwe ngenqubo ekhethekile yokuxhumanisa i-irradiation cross-linking, ama-polymer aqondile aguqulwa abe ama-polymers asebenza kahle anesakhiwo senethiwekhi esinezinhlangothi ezintathu. Inikeza ukumelana okuhle kwe-UV, ukumelana nokushisa, ukumelana nokubanda, kanye nezakhiwo zemishini. Ngokuguquguquka okukhulu nokumelana nesimo sezulu kune-XLPE, kulula ukuyifaka nokuyiqondisa ezakhiweni eziyinkimbinkimbi—okuyenza ifaneleke ngokukhethekile kumaphaneli elanga ophahleni noma amasistimu afanayo abekwe phansi.

Inhlanganisela yethu ye-XLPO yamakhebuli e-photovoltaic ithobela i-RoHS, i-REACH, kanye nezinye izindinganiso zemvelo zamazwe ngamazwe. Ihlangabezana nezidingo zokusebenza ze-EN 50618:2014, TÜV 2PfG 1169, kanye ne-IEC 62930:2017, futhi ifanele ukusetshenziswa ku-insulation kanye nezendlalelo ze-sheath zezintambo ze-photovoltaic. Impahla iqinisekisa ukuphepha kwemvelo ngenkathi ihlinzeka ngokugeleza okuhle kakhulu kokucubungula kanye ne-extrusion surface ebushelelezi, ithuthukisa ukusebenza kahle kokukhiqiza ikhebula nokuvumelana komkhiqizo.

Ukumelana Nomlilo Namanzi
I-XLPO, ngemva kokuxhumanisa i-irradiation, inezinto ezingokwemvelo ezivimbela ilangabi. Igcina ukuzinza ngaphansi kokushisa okuphezulu nokucindezela, inciphisa kakhulu ingozi yomlilo. Iphinde isekele ukumelana namanzi okukalwe nge-AD8, okuyenza ifaneleke endaweni enomswakama noma enemvula. Ngokuphambene, i-XLPE ayinakho ukuvinjelwa komlilo okungokwemvelo futhi ifaneleka kangcono kumasistimu adinga ukumelana kwamanzi okuqinile. Nakuba i-PVC inamandla okuzicisha, ukuvutha kwayo kungase kukhiphe amagesi ayinkimbinkimbi.

Ubuthi kanye Nomphumela Wemvelo
I-XLPO ne-XLPE zombili izinto ezingenayo i-halogen, intuthu ephansi ezingakhiphi igesi ye-chlorine, ama-dioxin, noma inkungu ye-acid elimazayo ngesikhathi sokusha, enikeza ubungane obukhulu bemvelo. I-PVC, ngakolunye uhlangothi, ingakhipha amagesi ayingozi kubantu nasemvelweni emazingeni aphezulu okushisa. Ngaphezu kwalokho, izinga eliphezulu lokuxhumanisa ku-XLPO liyinikeza impilo ende yesevisi, okusiza ukwehlisa izindleko zesikhathi eside zokumiselela nokulungisa.

I-XLPO ne-XLPE
Izimo zohlelo lokusebenza: Izitshalo ezinkulu zamandla elanga ezifundeni ezinokukhanya kwelanga okuqinile noma izimo zezulu ezinzima, uphahla lwelanga lezentengiselwano nezimboni, amaqoqo elanga abekwe phansi, amaphrojekthi angaphansi komhlaba amelana nokugqwala.
Ukuvumelana nezimo zabo kusekela izakhiwo eziyinkimbinkimbi, njengoba izintambo zidinga ukuzulazula izithiyo noma zibhekane nokulungiswa okuvamile ngesikhathi sokufakwa. Ukuqina kwe-XLPO ngaphansi kwezimo zezulu ezimbi kakhulu kuyenza ibe ukukhetha okuthembekile ezifundeni ezinokushintshashintsha kwezinga lokushisa kanye nezimo ezinzima. Ikakhulukazi kumaphrojekthi we-photovoltaic anezidingo eziphezulu zokuhoxiswa komlilo, ukuvikelwa kwemvelo, nokuphila isikhathi eside, i-XLPO igqama njengento ethandwayo.

I-PVC
Izimo zohlelo lokusebenza: Ukufakwa kwe-solar endlini, amasistimu elanga anomthunzi ophahleni, namaphrojekthi ezindaweni ezipholile ezinokuchayeka elangeni okulinganiselwe.
Nakuba i-PVC ine-UV ephansi nokumelana nokushisa, isebenza kahle ezindaweni ezivezwe ngokumaphakathi (njengamasistimu asendlini noma amasistimu angaphandle anomthunzi kancane) futhi inikeza inketho evumelana nesabelomali.
