1. Cov ntsiab lus tooj liab yog tus nqi tsav tsheb loj tshaj plaws
Tooj liab yog tus nqi tseem ceeb nyob rau hauv tus qauv 6 mm² PV cable. Nws tus nqi lag luam txav mus tas li, thiab cov nqi tooj liab thoob ntiaj teb tsis ntev los no tseem muaj kev hloov pauv loj heev. Qhov ntawd txhais tau hais tias cov neeg muag khoom yuav tooj liab ntawm lub sijhawm sib txawv yuav twb muaj cov nqi tsim khoom sib txawv.
Qhov tseem ceeb tshaj, "6 mm²" ntawm cov lus hais tsis yog ib txwm txhais tau tias tib lub ntsiab lus ntawm tus neeg xyuas pib. Tus neeg xyuas pib ua raws li yuav tsum ua kom tau raws li qhov xav tau ntawm kev tiv thaiv thiab kev tsim kho raws li IEC 60228. Ib lub xov tooj uas tsis muaj tooj liab, cov hlua tsis txaus, lossis cov neeg xyuas pib ntau dhau yuav raug nqi pheej yig dua, tab sis nws yuav tsim kom muaj hluav taws xob ntau dua thiab kub ntau hauv kev ua haujlwm.
Rau cov neeg yuav khoom, cov lus nug tseem ceeb tsis yog:Puas yog nws cim 6 mm²?
Nws yog:Puas yog tus neeg xyuas pib tsis kam kuaj xyuas qhov tseeb 6 mm² cable?
2. Cov tooj liab liab thiab tinned tooj liab tsis zoo ib yam
Ntau PV cables siv tinned tooj liab conductors es tsis txhob liab qab tooj liab. Cov txheej txheej nyias nyias pab tiv thaiv tus neeg xyuas pib los ntawm oxidation thiab corrosion, uas yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov av noo, ntug dej hiav txwv, kev lag luam, lossis ntev - lub neej nyob sab nraum zoov.
Tinned tooj liab feem ntau raug nqi ntau dua vim nws ntxiv cov khoom siv thiab kev ua haujlwm. Qhov sib txawv yuav tsis zoo heev ntawm ib 'meter' ntawm cable, tab sis hla ntau txhiab meters, nws dhau los ua lub ntsiab lus.
Rau luv luv-lub sij hawm, qis- daim ntawv thov kev pheej hmoo, cov neeg yuav khoom yuav tsom rau tus nqi. Rau lub ru tsev, cov phiaj xwm ntug dej hiav txwv, lossis kev teeb tsa yuav tsum ua haujlwm tau ntau xyoo, kev tiv thaiv tus neeg xyuas pib tsim nyog tau txais kev saib xyuas ntxiv.
3. Daim ntawv pov thawj yog ntau tshaj li lub logo luam tawm
Ib lub cable tuaj yeem nqa tau zoo sib xws - saib cov cim thaum muab ntau qib sib txawv ntawm kev ua raws.
Rau cov phiaj xwm PV niaj hnub no, cov neeg yuav khoom yuav tsum xyuas seb lub cable puas muaj ntawv pov thawj tiag tiag rau cov qauv kev lag luam, xws liTS EN 50618 / IEC 62930rau kev siv 1,500 V DC hnub ci cable, los yogTIAB SA 4703rau North American PV hlau. Cov qauv no npog ntau tshaj qhov ntsuas hluav taws xob. Lawv hais txog kev ua tau zoo uas cuam tshuam txog qhov raug tshav ntuj, qhov kub thiab txias, rwb thaiv tsev, cov ntaub ntawv lub tsho, thiab ntev - siv sab nraum zoov.
Cov ntawv pov thawj tiag tiag suav nrog kev sim, kev tswj xyuas lub Hoobkas, cov ntaub ntawv, thiab kev saib xyuas ib ntus. Qhov ntawd ntxiv tus nqi, tab sis nws kuj txo qhov kev pheej hmoo ntawm qhov project.
Nco ntsoov nug tus lej ntawv pov thawj, tus tuav daim ntawv pov thawj, qhov chaw tsim khoom, thiab cov qauv siv cable raws nraim. Daim ntawv pov thawj siv tau rau ib yam khoom tsis tuaj yeem npog txhua lub cable uas tus neeg muag khoom muag.
4. "Tag nrho cov tooj liab" thiab "tag nrho meter" yuav tsum tau kuaj xyuas
Ob lub 100-meter yob yuav tsis muaj tib tus nqi ntawm cov khoom siv cable.
Qee qhov qis- nqe muab yog raws li qhov hnyav ntawm tus neeg xyuas pib, thinner rwb thaiv tsev los yog sheath, los yog luv dua qhov tseeb yob ntev. Cov ntsiab lus no nyuaj rau pom hauv cov duab khoom, tab sis lawv cuam tshuam rau ob qho tib si installation nqi thiab ntev - lub sij hawm hluav taws xob ua haujlwm.
Kev sib piv cov tswv yim yuav tsum muaj xws li:
Net nyhav ib 100 m yob
Qhov tseeb conductor kuj
rwb thaiv tsev thiab sheath thickness
Qhov tseeb ntsuas qhov ntev ib yob
Daim ntawv ntsuam xyuas thiab kab cim kab
Tus nqi qis dua tsis yog kev txuag yog tias qhov project xav tau cable ntxiv, ntsib kev poob siab dua, lossis ntsib kev tsis lees paub thaum kuaj xyuas.
5. Cov nqe lus ntim thiab xa khoom tuaj yeem hloov tus nqi kawg
Kev ntim khoom yog lwm qhov tsis pom zoo. Cov hnab yas yooj yim, xa tawm- cov thawv ntawv qib, ntoo reels, fumigated pallets, thiab cov ntawv customized txhua tus muaj cov nqi sib txawv.
Tib yam siv rau cov nqe lus lag luam. EXW, FOB, CIF, DAP, thiab DDP tsis suav nrog tib lub luag haujlwm. Freight, export tuav, kev tuav pov hwm, qhov chaw tsub nqi, kev lis kev cai clearance, lub luag hauj lwm, thiab kev xa khoom hauv zos yuav zaum nrog tus neeg muag khoom lossis tus neeg yuav khoom nyob ntawm qhov pom zoo Incoterm.
Yog li ua ntej sib piv cov nqi, xyuas kom tseeb tias cov lus hais siv tib lub cable specification, yob ntev, ntim cov qauv, kom muaj nuj nqis, thiab lub sijhawm xa khoom.
Kab hauv qab
Qhov pheej yig tshaj 6 mm² hnub ci cable tsis yog qhov qis tshaj - tus nqi xaiv rau PV project.
Qhov kev txiav txim siab yuav zoo dua los ntawm kev sib piv cov pob tiav: tus neeg xyuas pib zoo, tinning, cov ntaub ntawv pov thawj, qhov tseeb cable ntev, ntim, thiab xa khoom. Hauv cov phiaj xwm hnub ci, tus nqi cable tsuas yog ib feem me me ntawm tag nrho cov peev txheej -tab sis cable tsis ua haujlwm, rov ua dua tshiab, thiab ploj tiam tuaj yeem kim dua li qhov pib tus nqi sib txawv.
