Inani elikhulu leentambo ze-DC kwizikhululo zamandla elanga kufuneka zibekwe ngaphandle, kwaye iimeko zokusingqongileyo zinzima.Izinto zekhebula kufuneka zisekelwe ekuchaseni imisebe ye-ultraviolet, i-ozone, utshintsho olubi lokushisa kunye nokukhukuliseka kweekhemikhali.Ukusetyenziswa kwexesha elide lezinto eziqhelekileyo kule ndawo kuya kubangela ukuba i-cable sheath ibe buthathaka kwaye idibanise i-cable insulation.Ezi meko ziya kulimaza ngokuthe ngqo inkqubo yekhebula, kwaye ngexesha elifanayo liya kwandisa umngcipheko we-cable short circuit.Ngexesha eliphakathi kunye nexesha elide, ukubakho komlilo okanye ukulimala komntu kuphezulu, okuchaphazela kakhulu ubomi benkonzo yenkqubo.
Ngoko ke,kubaluleke kakhulu ukusebenzisaiintambo zesola DCkunye namacandelo kwizikhululo zamandla elanga.Iintambo ezikhethekileyo ze-photovoltaic kunye namacandelo azinakho kuphela ukuchasana nomoya kunye nemvula, i-UV kunye ne-ozone erosion, kodwa inokumelana noluhlu olubanzi lokutshintsha kweqondo lokushisa (umzekelo: ukusuka -40 ukuya kwi-125 ° C).EYurophu, amagcisa aphumelele iimvavanyo kwaye iqondo lokushisa elilinganisiweyo phezu kophahla liphezulu njenge-100-110 ° C.
Kwiimeko ezininzi, iintambo ze-DC ezisetyenziswa kwizikhululo zamandla elanga zisetyenziselwa umsebenzi wangaphandle wexesha elide.Ngenxa yokukhawulelana neemeko zokwakha, iziqhagamshelo zisetyenziselwa ukudibanisa intambo.Izinto zomqhubi wekhebula zinokwahlulwa zibe yintsimbi yobhedu kunye ne-aluminium core.I-Copper core cable inengcono ukumelana ne-oxidation kune-aluminiyam, ubomi obude, uzinzo oluhle, ukuhla kwamandla ombane aphantsikwayeilahleko yamandla aphantsi;ekwakhiweni, kuba i-copper core iguquguqukayo kwaye i-radius ye-bend evumelekileyo incinci, ikulungele ukujika nokudlula kumbhobho;kwaye isiseko sobhedu sichasene nokudinwa kunye nokugoba ngokuphindaphindiweyo akulula ukuphula, ngoko ke i-wiring ikulungele;kwangaxeshanye, undoqo wobhedu unamandla omatshini aphezulu kwaye unokumelana noxinzelelo olukhulu lomatshini, nto leyo izisa uncedo olukhulu kulwakhiwo kunye nokubeka, kwaye idala iimeko zokwakhiwa komatshini.Ngokuchasene noko, iintambo ze-aluminiyam ezingundoqoiqhelekile kwi-oxidation(i-electrochemical reaction) kumalungu ofakelo ngenxa yeempawu zeekhemikhali ze-aluminiyam, ngakumbi i-creep phenomena, enokukhokelela ngokululaukusilela.
Ke ngoko, iintambo zobhedu zineenzuzo ezibalaseleyo ekusetyenzisweni kwezikhululo zamandla elanga, ngakumbi kwintsimi yonikezelo lwamandla ekhebula ngqo.Inokunciphisa izinga lengozi, iphucule ukuthembeka kokunikezelwa kwamandla, kwaye ilungele ukwakhiwa, ukusebenza kunye nokugcinwa.Esi sizathu sokuba kutheni iintambo zobhedu zisetyenziselwa ukunikezelwa kwamandla angaphantsi komhlaba e-China.
Ukumelana nobushushu obuphezulu, ukumelana nokubanda, ukumelana neoyile, iasidi kunye nokumelana netyuwa yealkali, ukunganyangeki kwe-UV, ukubuyiswa komlilo, ukukhuselwa kwendalo., iintambo zamandla elanga zisetyenziswa ikakhulu kwiindawo ezibuhlungu kunye nobomi benkonzo obungaphezuluIminyaka engama-25.
Iintambo zelanga zivame ukuvezwa elangeni, kwaye iinkqubo zelanga zihlala zisetyenziselwa kwiindawo ezinzima, ezifanaubushushu obuphantsikwayeimitha ye-ultraviolet.Ekhaya okanye phesheya, xa imozulu ilungile, obona bushushu bobushushu belanga buya kuba buphezulu kangange-100℃.Izinto ezahlukeneyo ezinokuthi zisetyenziswe kwiintambo eziqhelekileyo zikumgangatho ophezulu wezinto zokudibanisa eziphothiweyo ezifana ne-polyvinyl chloride (PVC), irabha, i-TPE kunye ne-XLPE, kodwa ilusizi ukuba ubushushu obuphezulu bomgangatho ophezulu kwiintambo eziqhelekileyo Ukongeza, nkqu i-PVC egqunyiweyo. iintambo ezinobushushu obuyi-70°C zihlala zisetyenziswa ngaphandle, kodwa azikwazi ukuhlangabezana neemfuno zobushushu obuphezulu, ukukhuselwa kwe-UV, kunye nokumelana nokubanda.Kunokubonwa ukuba izikhululo zamandla elanga kufuneka zikhethe iintambo ezithembekileyo ze-solar dc.
Iingenelo of slocable iintambo zesola DC

Ngexesha lofakelo kunye nokusebenza kunye nokugcinwa kwezikhululo zamandla elanga, iintambo zinokuthi zihanjiswe kumhlaba ongaphantsi komhlaba, zikhuliswe lukhula kunye namatye, kwiindawo ezibukhali zesakhiwo sophahla, kwaye zibekwe emoyeni.Iintambo zisenokuthwala amandla ahlukeneyo angaphandle.Ukuba i-cable sheath ayinamandla ngokwaneleyo,i-cable insulation layer iya konakala, eya kuchaphazela ubomi benkonzo yentambo yonke, okanye imbangelaintambo emfutshane, umlilo, kwayeiingozi zokwenzakala zobuqu.Uphando lwenzululwazi ngekhebula kunye nabasebenzi bobuchwephesha bafumanise ukuba imathiriyeli edityaniswe ngokunqamlezileyo yimitha yombane inamandla omatshini aphezulu kunangaphambili kunyango lwemitha.Inkqubo yokudibanisa umnqamlezo itshintsha ubume bemichiza yepolymer ye-cable insulation sheath material, i-fusible thermoplastic material iguqulwa ibe yi-non-fusible elastomeric material, kunye ne-radiation-linking cross-linking iphucula kakhulu i-thermal, i-mechanical kunye nepropathi yombane yentambo. izinto zokugquma.Iimpawu zeMichiza.
I-loop ye-DC isoloko ichaphazeleka ngeendlela ezahlukeneyo ezingathandekiyo ngexesha lokusebenza, okubangelwa ukumisa, okwenza inkqubo ingakwazi ukusebenza ngokuqhelekileyo.Okufana ne-extrusion, ukuveliswa kwentambo engafanelekanga, izinto zokugquma ezingafanelekanga, ukusebenza kwe-insulation ephantsi, ukuguga kwe-DC system insulation, okanye iziphene ezithile zomonakalo ezinokubangela ukumisa okanye zibe yingozi yomhlaba.
Kwiintambo ze-solar dc, ngexesha lofakelo kunye nokufakwa kwesicelo, iintambo ziyakwazi ukuhanjiswa kwiindawo ezibukhali zokwakheka kwephahla.Ngexesha elifanayo, iintambo kufuneka zimelaneuxinzelelo, ukugoba, Ukuxinezeleka, ukuxinana kwemithwalokwayeukuxhathisa impembelelo enamandla, ephezulu kuneentambo eziqhelekileyo ze-dc.Ukuba usebenzisa iintambo ze-dc eziqhelekileyo, i-sheath inayoukusebenza kakubi kwe-UV yokukhusela, okuya kubangela ukuba i-sheath yangaphandle yekhebula iguge, eya kuchaphazela ubomi benkonzo yentambo, engakhokelela ekubonakaleni kwee-short-circuits, i-alamu yomlilo, kunye nokulimala okuyingozi kubasebenzi.
Emva kokuba i-radiated, i-solar dc cable insulation sheath ineempawu zokumelana nobushushu obuphezulu, ukuxhathisa kwimitha ye-ultraviolet, ukumelana ne-oyile, kunye nokumelana nokubanda.Ubomi benkonzo bungaphezulu kweminyaka engama-25, engenakuqhathaniswa neentambo eziqhelekileyo ze-dc.
