Inombolo enkulu yezintambo ze-DC eziteshini zikagesi welanga zidinga ukubekwa ngaphandle, futhi izimo zemvelo zinzima.Izinto zekhebula kufanele zisekelwe ekuphikiseni imisebe ye-ultraviolet, i-ozone, izinguquko ezinzima zokushisa kanye nokuguguleka kwamakhemikhali.Ukusetshenziswa isikhathi eside kwezinto ezijwayelekile kule ndawo kuzodala ukuthi i-cable sheath ibe ntekenteke futhi ibole nokufaka ikhebula.Lezi zimo zizolimaza ngokuqondile uhlelo lwekhebula, futhi ngesikhathi esifanayo zizokwandisa ingozi ye-cable short circuit.Esikhathini esimaphakathi nesikhathi eside, amathuba omlilo noma ukulimala komuntu siqu nawo aphezulu, okuthinta kakhulu impilo yesevisi yesistimu.
Ngakho-ke,kudingekile kakhulu ukusebenzisaizintambo ze-solar dckanye nezingxenye eziteshini zikagesi welanga.Izintambo ezikhethekile ze-photovoltaic nezingxenye azigcini nje ngokukwazi ukumelana nomoya nemvula, ukuguguleka kwe-UV ne-ozone, kodwa futhi zingakwazi ukumelana noshintsho olubanzi lokushisa (isibonelo: kusuka ku--40 kuya ku-125 ° C).EYurophu, ochwepheshe baphumelele izivivinyo futhi izinga lokushisa elilinganiselwe ophahleni liphezulu njenge-100-110 ° C.
Ezimweni eziningi, izintambo ze-DC ezisetshenziswa eziteshini zamandla elanga zisetshenziselwa umsebenzi wangaphandle wesikhathi eside.Ngenxa yomkhawulo wemibandela yokwakha, izixhumi zisetshenziswa kakhulu ekuxhumekeni kwekhebula.Izinto ze-cable conductor zingahlukaniswa zibe yi-copper core kanye ne-aluminium core.Ikhebula eliwumgogodla wethusi linayoukumelana okungcono kwe-oxidation kune-aluminium, impilo ende, ukuzinza okuhle, ukwehla kwamandla kagesi aphansifuthiukulahlekelwa amandla aphansi;ekwakhiweni, ngenxa yokuthi umgogodla wethusi uyaguquguquka futhi i-radius yokugoba evumelekile incane, kulula ukujika nokudlula ipayipi;futhi umgogodla wethusi umelana nokukhathala futhi ukugoba okuphindaphindiwe akulula ukuphuka, ngakho-ke i-wiring ilula;ngesikhathi esifanayo, umgogodla wethusi unamandla amakhulu emishini futhi ungamelana nokucindezeleka okukhulu kwemishini, okuletha ukunethezeka okukhulu ekwakhiweni nasekubekweni, futhi kudala izimo zokwakha imishini.Ngokuphambene nalokho, izintambo eziwumgogodla we-aluminiumethambekele ku-oxidation(i-electrochemical reaction) emalungeni okufaka ngenxa yezakhiwo zamakhemikhali zezinto ze-aluminium, ikakhulukazi izenzakalo ezinwabuzelayo, ezingaholela kalulaukwehluleka.
Ngakho-ke, izintambo zethusi zinezinzuzo ezivelele ekusetshenzisweni kweziteshi zamandla elanga, ikakhulukazi emkhakheni wokunikezwa kwamandla kagesi okungcwatshwe ngokuqondile.Inganciphisa izinga lezingozi, ithuthukise ukwethembeka kokuphakelwa kukagesi, futhi ilungele ukwakhiwa, ukusebenza kanye nokunakekelwa.Lesi isizathu esenza izintambo zethusi zisetshenziswe ngokuyinhloko ekunikezeni amandla angaphansi komhlaba e-China.
Ukumelana nokushisa okuphezulu, ukumelana nokubanda, ukumelana nowoyela, i-asidi ne-alkali ukumelana nosawoti, ukumelana ne-UV, i-flame retardant, ukuvikelwa kwemvelo, izintambo zamandla elanga zisetshenziswa ikakhulukazi ezindaweni ezinokhahlo nempilo yesevisi engaphezuIminyaka engu-25.
Izintambo ze-solar zivame ukuchayeka elangeni, futhi izinhlelo zelanga zivame ukusetshenziswa ezindaweni ezinokhahlo, njengeizinga lokushisa eliphansifuthiimisebe ye-ultraviolet.Ekhaya noma phesheya, lapho isimo sezulu sisihle, izinga lokushisa eliphakeme kakhulu lesimiso sonozungezilanga lizoba phezulu njenge-100℃.Izinto ezihlukahlukene ezingasetshenziselwa izintambo ezijwayelekile ziyizinto eziphezulu zokuxhumanisa ezihlanganisiwe ezifana ne-polyvinyl chloride (PVC), irabha, i-TPE ne-XLPE, kodwa kuyadabukisa ukuthi izinga lokushisa eliphakeme kakhulu likalwe izintambo ezivamile Ngaphezu kwalokho, ngisho PVC insulated. izintambo ezinezinga lokushisa elilinganiselwe elingu-70°C zivame ukusetshenziswa ngaphandle, kodwa azikwazi ukuhlangabezana nezimfuneko zokushisa okuphezulu, ukuvikelwa kwe-UV, nokumelana nokubanda.Kungabonakala ukuthi iziteshi zamandla elanga kufanele zikhethe izintambo ezithembekile ze-solar dc.

Phakathi nokufakwa nokusebenza nokugcinwa kweziteshi zikagesi welanga, izintambo zingase zihanjiswe enhlabathini engaphansi komhlaba, zigqitshwe ukhula namadwala, emaphethelweni acijile esakhiwo sophahla, futhi zichayeke emoyeni.Izintambo zingase zithwale amandla ahlukahlukene angaphandle.Uma umgodla wekhebula ungaqinile ngokwanele,ungqimba lwe-cable insulation luzolimala, oluzothinta impilo yesevisi yekhebula lonke, noma imbangelai-short-circuit, umlilo, futhiizingozi zokulimala komuntu siqu.Ucwaningo lwesayensi yekhebula kanye nabasebenzi bezobuchwepheshe bathole ukuthi into exhunywe ngokuphambana ngemisebe inamandla amakhulu emishini kunangaphambili kokwelashwa ngemisebe.Inqubo yokuxhumanisa ishintsha ukwakheka kwamakhemikhali e-polymer ye-cable insulation sheath material, i-fusible thermoplastic material iguqulwa ibe yi-non-fusible elastomeric material, kanti imisebe exhumanisa i-cross-linking ithuthukisa kakhulu izakhiwo ezishisayo, zemishini kanye nezikagesi zekhebula. Insulation impahla.Izakhiwo zamakhemikhali.
I-loop ye-DC ivame ukuthinteka yizici ezihlukahlukene ezingathandeki ngesikhathi sokusebenza, okuholela ekusekelweni, okwenza uhlelo lungakwazi ukusebenza ngokujwayelekile.Okufana nokukhishwa kwe-extrusion, ukukhiqizwa kwekhebula okungekuhle, okokufaka okungafanelekile, ukusebenza kancane kokufakelwa, ukuguga kwe-insulation yesistimu ye-DC, noma ukonakala okuthile okungabangela ukumisa phansi noma kube yingozi ephansi.
Ngezintambo ze-solar dc, ngesikhathi sokufakwa nokufaka isicelo, izintambo zingahanjiswa emikhawulweni ebukhali yesakhiwo sophahla.Ngesikhathi esifanayo, izintambo kufanele zimelaneingcindezi, ukugoba, ukungezwani, imithwalo eqinile ehlangenefuthiukumelana nomthelela onamandla, ephakeme kunezintambo ezijwayelekile ze-dc.Uma usebenzisa izintambo ezijwayelekile ze-dc, i-sheath ineukusebenza kabi kokuvikela kwe-UV, okuzokwenza ukuthi i-sheath yangaphandle yekhebula iguge, okuzothinta impilo yesevisi yekhebula, okungaholela ekubukeni kwama-short-circuits, ama-alamu omlilo, nokulimala okuyingozi kubasebenzi.
Ngemuva kokufakwa imisebe, i-solar dc cable insulation sheath inezindawo zokumelana nokushisa okuphezulu, ukumelana nemisebe ye-ultraviolet, ukumelana nowoyela, nokumelana nokubanda.Impilo yesevisi ingaphezu kweminyaka engama-25, engenakuqhathaniswa nezintambo ezijwayelekile ze-dc.
