Ntau tus DC cables nyob rau hauv lub hnub ci fais fab chaw nres tsheb yuav tsum tau muab tso rau sab nraum zoov, thiab tej yam ntuj tso tej yam kev mob yog hnyav.Cov ntaub ntawv cable yuav tsum tau ua raws li kev tiv thaiv rau ultraviolet rays, ozone, kub hloov pauv thiab tshuaj yaig.Kev siv cov ntaub ntawv zoo tib yam nyob rau hauv ib puag ncig no yuav ua rau lub cable sheath tsis yooj yim sua thiab txawm decompose lub rwb thaiv tsev cable.Cov xwm txheej no yuav cuam tshuam ncaj qha rau cable system, thiab tib lub sijhawm yuav ua rau muaj kev pheej hmoo ntawm cable luv Circuit Court.Nyob rau hauv nruab nrab thiab ntev, qhov muaj peev xwm ntawm hluav taws kub lossis kev raug mob ntawm tus kheej kuj yog siab dua, uas cuam tshuam rau lub neej kev pab cuam ntawm lub cev.
Yog li ntawd,nws yog ib qho tsim nyog yuav tau sivhnub ci dc cablesthiab cov khoom siv hauv cov chaw siv hluav taws xob hnub ci.Tshwj xeeb photovoltaic cables thiab cov khoom siv tsis yog tsuas yog muaj qhov zoo tshaj plaws tiv thaiv cua thiab nag, UV thiab ozone yaig, tab sis kuj tuaj yeem tiv taus ntau yam kev hloov pauv kub (piv txwv li: ntawm -40 txog 125 ° C).Hauv Tebchaws Europe, cov kws tshaj lij tau dhau qhov kev sim thiab ntsuas qhov ntsuas kub ntawm lub ru tsev yog siab li 100-110 ° C.
Feem ntau, DC cables siv nyob rau hauv lub hnub ci fais fab chaw nres tsheb yog siv rau sab nraum zoov ua hauj lwm mus sij hawm ntev.Vim muaj kev txwv ntawm kev tsim kho, cov khoom sib txuas feem ntau yog siv rau kev sib txuas cable.Cable conductor cov ntaub ntawv tuaj yeem muab faib ua tooj liab thiab txhuas core.Copper core cable muajoxidation kuj zoo dua li txhuas, lub neej ntev, zoo stability, low voltage poobthiabtsis muaj zog poob;nyob rau hauv kev tsim kho, vim hais tias cov tub ntxhais tooj liab yog hloov tau thiab qhov tso cai khoov vojvoog me me, nws yooj yim rau tig thiab hla cov yeeb nkab;thiab cov tub ntxhais tooj liab yog resistant rau qaug zog thiab rov khoov yog tsis yooj yim rau tawg, yog li cov xov hlau yog yooj yim;Nyob rau tib lub sijhawm, cov tub ntxhais tooj liab muaj lub zog ua haujlwm siab thiab tuaj yeem tiv taus kev sib tsoo ntau dua, uas ua rau muaj kev yooj yim rau kev tsim kho thiab tso, thiab tsim cov xwm txheej rau kev tsim kho tshuab.Ntawm qhov tsis sib xws, aluminium core cables yogyooj yim rau oxidation(electrochemical cov tshuaj tiv thaiv) nyob rau hauv lub installation pob qij txha vim cov tshuaj lom neeg cov khoom ntawm txhuas cov ntaub ntawv, tshwj xeeb tshaj yog creep phenomena, uas yuav ua tau yooj yim ua rau komua tsis tiav.
Yog li ntawd, tooj liab cables muaj qhov zoo tshaj plaws nyob rau hauv kev siv lub hnub ci fais fab chaw nres tsheb, tshwj xeeb tshaj yog nyob rau hauv lub tshav pob ncaj qha faus cable fais fab mov.Nws tuaj yeem txo qhov kev huam yuaj, txhim kho kev ntseeg tau ntawm cov khoom siv hluav taws xob, thiab yooj yim rau kev tsim kho, kev ua haujlwm thiab kev saib xyuas.Qhov no yog vim li cas tooj liab cables feem ntau yog siv hauv cov khoom siv hluav taws xob hauv av hauv Suav teb.
Kub kub tsis kam, txias tsis kam, roj kuj, acid thiab alkali ntsev kuj, UV kuj, nplaim retardant, ib puag ncig tiv thaiv, hnub ci fais fab cables yog tsuas yog siv nyob rau hauv hnyav ib puag ncig nrog ib tug kev pab cuam lub neej ntawm ntau tshaj25 xyoo.
Cov kab hluav taws xob hnub ci feem ntau raug rau lub hnub, thiab cov tshuab hnub ci feem ntau siv nyob rau hauv qhov chaw hnyav, xws likub kubthiabultraviolet hluav taws xob.Hauv tsev lossis txawv teb chaws, thaum huab cua zoo, qhov kub siab tshaj ntawm lub hnub ci yuav siab li 100 ℃.Cov khoom siv sib txawv uas tuaj yeem siv rau cov cables zoo tib yam yog cov khoom siv sib txuas zoo xws li polyvinyl chloride (PVC), roj hmab, TPE thiab XLPE, tab sis nws yog ib qho kev khuv xim uas qhov ntsuas kub siab tshaj plaws rau cov cables zoo tib yam ntxiv, txawm tias PVC insulated. cables nrog ntsuas kub ntawm 70 ° C feem ntau siv sab nraum zoov, tab sis lawv tsis tuaj yeem ua tau raws li qhov xav tau ntawm qhov kub thiab txias, tiv thaiv UV, thiab tiv thaiv txias.Nws tuaj yeem pom tias cov chaw nres tsheb hnub ci yuav tsum xaiv cov hnub ci dc cables uas ntseeg tau.
Qhov zoo of yooj yim hnub ci dc cables
| Ib txwm DC cables | Hnub ci DC cables | |
| rwb thaiv tsev | Irradiation cross-linked polyolefin rwb thaiv tsev | PVC lossis XLPE rwb thaiv tsev |
| lub tsho | Irradiation cross-linked polyolefin rwb thaiv tsev | PVC hnab |
Thaum lub sij hawm kev teeb tsa thiab kev ua haujlwm thiab kev saib xyuas cov chaw nres tsheb hnub ci, cov kab hluav taws xob yuav raug xa mus rau hauv cov av hauv qab av, overgrown nrog cov nroj tsuag thiab pob zeb, ntawm cov npoo ntse ntawm lub ru tsev, thiab raug huab cua.Cov kab hluav taws xob tuaj yeem dais ntau lub zog sab nraud.Yog hais tias lub cable sheath tsis muaj zog txaus,txheej rwb thaiv tsev cable yuav raug puas tsuaj, uas yuav cuam tshuam rau kev pab cuam lub neej ntawm tag nrho cov cable, los yog ua rauluv-circuit, hluav taws, thiabkev raug mob ntawm tus kheej.Cable scientific kev tshawb fawb thiab cov neeg ua haujlwm tau pom tias cov khoom sib txuas los ntawm hluav taws xob muaj zog dua txhua yam ua ntej kev kho hluav taws xob.Cov txheej txheem kev sib txuas sib txuas hloov pauv cov qauv tshuaj ntawm cov polymer ntawm cov khoom siv hluav taws xob rwb thaiv tsev, cov khoom siv thermoplastic fusible hloov mus rau cov khoom siv elastomeric uas tsis yog fusible, thiab kev sib txuas hluav taws xob cuam tshuam tau zoo txhim kho cov thermal, mechanical thiab hluav taws xob ntawm lub cable. cov khoom siv rwb thaiv tsev.Cov khoom siv tshuaj.
Lub voj DC feem ntau cuam tshuam los ntawm ntau yam tsis zoo thaum lub sijhawm ua haujlwm, ua rau hauv av, ua rau lub cev tsis tuaj yeem ua haujlwm li qub.Xws li extrusion, tsis zoo cable manufacturing, tsis tsim nyog cov ntaub ntawv rwb thaiv tsev, tsis tshua muaj rwb thaiv tsev kev ua tau zoo, kev laus ntawm lub DC system rwb thaiv tsev, los yog tej yam kev puas tsuaj uas yuav ua rau grounding los yog ua ib tug grounding txaus ntshai.
Rau cov hnub ci dc cables, thaum lub sij hawm installation thiab daim ntawv thov, cov cables yuav raug routed ntawm lub ntse npoo ntawm lub ru tsev layout.Nyob rau tib lub sijhawm, cov cables yuav tsum tiv taussiab, khoov, tension, interlaced tensile loadsthiabmuaj zog cuam tshuam tsis kam, uas yog superior rau ib txwm dc cables.Yog tias koj siv cov dc cables ib txwm muaj, lub plhaub muajtsis zoo UV tiv thaiv kev ua haujlwm, uas yuav ua rau lub tsho sab nrauv ntawm lub cable mus rau lub hnub nyoog, uas yuav cuam tshuam rau lub neej kev pab cuam ntawm lub cable, uas tuaj yeem ua rau cov tsos ntawm luv luv, ceeb toom hluav taws, thiab kev raug mob txaus ntshai rau cov neeg ua haujlwm.
Tom qab tau irradiated, lub hnub ci dc cable rwb thaiv tsev sheath muaj cov khoom ntawm kub tsis kam, ultraviolet hluav taws xob tsis kam, roj tsis kam, thiab txias tsis kam.Lub neej kev pab cuam yog ntau tshaj 25 xyoo, uas yog incomparable nrog ib txwm dc cables.
