Huwandu hukuru hwetambo dzeDC mumagetsi ezuva dzinoda kuiswa panze, uye mamiriro ekunze akaomarara.Iyo tambo zvinhu zvinofanirwa kuve zvichibva pakupokana kune ultraviolet mwaranzi, ozone, yakanyanya tembiricha shanduko uye kukukurwa kwemakemikari.Kushandiswa kwenguva refu kwezvinhu zvakajairwa munzvimbo ino kuchaita kuti tambo sheath ive isina kusimba uye kunyange kuora tambo yekuvharisa.Aya mamiriro achakuvadza zvakananga iyo tambo system, uye panguva imwechete ichawedzera njodzi yetambo pfupi.Munguva yepakati uye kwenguva refu, mukana wemoto kana kukuvara kwemunhu wakakwira zvakare, izvo zvinokanganisa zvakanyanya hupenyu hwebasa rehurongwa.
Naizvozvo,zvakakosha zvikuru kushandisasolar dc cablesuye zvinoriumba muzviteshi zvemagetsi ezuva.Special photovoltaic cables uye zvikamu hazvisi chete zvinonyanya kupikisa mhepo nemvura, UV uye ozone erosion, asiwo inogona kumira nehupamhi hwekuchinja kwekushisa (somuenzaniso: kubva -40 kusvika 125 ° C).MuEurope, vanamazvikokota vakapasa bvunzo uye tembiricha yakayerwa padenga yakakwira kusvika 100-110 ° C.
Muzviitiko zvakawanda, tambo dzeDC dzinoshandiswa mumagetsi ezuva dzinoshandiswa kuita basa rekunze kwenguva refu.Nekuda kwekudzikisira kwemamiriro ekuvaka, zvibatanidza zvinonyanya kushandiswa kubatanidza tambo.Cable conductor zvinhu zvinogona kukamurwa kuita copper core uye aluminium musimboti.Copper core cable inenani oxidation kuramba pane aluminium, hupenyu hurefu, kugadzikana kwakanaka, low voltage dropuyekuderera kwesimba kurasikirwa;mukuvaka, nekuti mhangura yemhangura inoshanduka uye inotenderwa bend radius idiki, zviri nyore kutendeuka uye kupfuura nepapombi;uye mhangura yemhangura inopesana nekuneta uye kudzokorora kukotama hakusi nyore kuputsa, saka wiring iri nyore;panguva imwecheteyo, iyo copper core ine yakakwira mechanical simba uye inokwanisa kumirisana nehukuru hwemakinika, izvo zvinounza kurerukirwa kukuru pakuvaka nekuisa, uye inogadzira mamiriro ekuvaka mechan.Pane zvinopesana, aluminium core cables ndeyeinowanzoitika kune oxidation(electrochemical reaction) mumajoini ekuisa nekuda kwemakemikari emhando yealuminium zvinhu, kunyanya zvinokambaira, izvo zvinogona kutungamira nyorekukundikana.
Naizvozvo, tambo dzemhangura dzine zvakatanhamara zvakanakira mukushandiswa kwemagetsi ezuva, kunyanya mumunda wekuvigwa zvakananga tambo magetsi.Inogona kuderedza chiyero chetsaona, kuvandudza kuvimbika kwemagetsi, uye yakanakira kuvaka, kushanda nekugadzirisa.Ichi ndicho chikonzero nei tambo dzemhangura dzinonyanya kushandiswa mumagetsi epasi pevhu muChina.
Kudzivirira kwekushisa kwepamusoro, kutonhora kutonhora, kuramba kwemafuta, asidhi uye alkali munyu kuramba, UV kuramba, kupisa kwemoto, kuchengetedza kwezvakatipoteredza., tambo dzemagetsi ezuva dzinonyanya kushandiswa munzvimbo dzakaomarara dzine hupenyu hwesevhisi hunopfuura25 makore.
Tambo dzezuva dzinowanzoiswa kuzuva, uye masisitimu ezuva anowanzoshandiswa munzvimbo dzakaoma, sengetembiricha yakadererauyeultraviolet mwaranzi.Kumba kana kunze kwenyika, kana mamiriro ekunze akanaka, tembiricha yepamusoro yesolar system ichakwira se100 ℃.Zvinhu zvakasiyana-siyana zvinogona kushandiswa kune akajairwa tambo ndezvepamusoro-mhando yakarukwa yekubatanidza zvinhu zvakaita se polyvinyl chloride (PVC), rabha, TPE uye XLPE, asi zvinonzwisa tsitsi kuti tembiricha yepamusoro-soro yetambo dzakajairwa Mukuwedzera, kunyange PVC insulated. tambo dzine tembiricha yakayerwa ye70°C dzinowanzo shandiswa panze, asi hadzikwanise kuzadzisa zvinodikanwa zvekupisa kwepamusoro, kudzivirira kweUV, uye kushorwa kwechando.Zvinogona kuoneka kuti solar magetsi zviteshi zvinofanirwa kusarudza akavimbika solar dc tambo.

Panguva yekugadzwa nekushanda nekuchengetedza zviteshi zvemagetsi ezuva, tambo dzinogona kufambiswa muvhu pasi pevhu, dzakakura nesora nematombo, pamicheto yakapinza yedenga remba, uye kuratidzwa nemhepo.Tambo idzi dzinogona kutakura masimba akasiyana ekunze.Kana iyo tambo sheath isina kusimba zvakakwana,iyo cable insulation layer ichakuvadzwa, izvo zvinokanganisa hupenyu hwesevhisi yetambo yese, kana chikonzeropfupi-circuit, moto,uyenjodzi dzekukuvara.Cable sainzi tsvakiridzo uye vashandi vehunyanzvi vakawana kuti zvinhu zvakachinjika-yakabatana nemwaranzi zvine simba repamusoro remuchina kupfuura kare kurapwa kwemwaranzi.Iyo muchinjika-yekubatanidza maitiro inoshandura chimiro chemakemikari yepolymer yetambo yekuisa sheath zvinhu, iyo fusible thermoplastic zvinhu inoshandurwa kuita isiri-fusible elastomeric zvinhu, uye muchinjika-unobatanidza radiation inovandudza zvakanyanya kupisa, mechanic uye magetsi zvimiro zvetambo. insulation zvinhu.Chemical properties.
Iyo DC loop inowanzobatwa nemhando dzakasiyana-siyana dzisina kunaka panguva yekushanda, zvichiita kuti ivhu, ichiita kuti sisitimu isakwanise kushanda zvakanaka.Zvakadai seextrusion, kutadza kugadzira tambo, zvigadziriso zvisina kukodzera, kuita kushoma kwesimbi, kuchembera kweiyo DC system insulation, kana kumwe kukanganisa kunokanganisa kunogona kukonzera pasi kana kuve njodzi yekumisa.
Kune solar dc tambo, panguva yekuisa uye kushandisa, tambo dzinogona kufambiswa pamipendero yakapinza yedenga remba.Panguva imwecheteyo, tambo dzinofanira kumirapressure, kukotama, tension, interlaced tensile mitorouyesimba rinokanganisa kuramba, iyo yakakwirira kune yakajairwa dc tambo.Kana iwe ukashandisa zvakajairika dc tambo, sheath ineyakashata UV kudzivirira kuita, iyo ichaita kuti sheath yekunze yetambo isvike, iyo inokanganisa hupenyu hwebasa retambo, izvo zvinogona kutungamirira pakuonekwa kwemafupi-circuits, maaramu emoto, uye kukuvara kune ngozi kune vashandi.
Mushure mekudziridzwa, solar dc cable insulation sheath ine zvimiro zvekupisa tembiricha kuramba, ultraviolet nemwaranzi kuramba, mafuta kuramba, uye kutonhora kuramba.Hupenyu hwesevhisi hunopfuura makore makumi maviri nemashanu, izvo zvisingaenzaniswi neakajairwa dc tambo.
