Thaum tsim thiab txhim kho lub hnub ci hluav taws xob, xaiv txoj cai cable loj yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig, kev nyab xeeb, thiab kev ua haujlwm ntev. Ntawm cov feem ntau siv hnub ci cable ntau thiab tsawg, 4mm² thiab 6mm² hnub ci cables yog cov kev xaiv nrov. Kev nkag siab txog qhov sib txawv ntawm qhov loj me ntawm cov kab no tuaj yeem pab txiav txim siab raws li qhov yuav tsum tau ua hauv lub cev.
Kab lus no qhia txog qhov sib txawv tseem ceeb ntawm 4mm thiab 6mm hnub ci cables, tsom mus rau lawv cov kev qhia tshwj xeeb, kev ua haujlwm, thiab kev siv.
Dab tsi yog Solar Cable?
Lub hnub ci cable (los yog hnub ci xaim) yog ib qho hluav taws xob tsim tshwj xeeb rau cov tshuab photovoltaic (PV). Nws txuas cov hnub ci vaj huam sib luag, inverters, thiab roj teeb, xa cov hluav taws xob tsim tau zoo thiab nyab xeeb. Hnub ci cables yog tsim los tiv thaiv ib puag ncig hnyav thiab nqa high voltages hauv DC systems.
Cov yam ntxwv tseem ceeb ntawm solar cables muaj xws li:
UV thiab huab cua tsis kam:Haum rau kev teeb tsa sab nraum zoov.
Durability:Resistant mus rau kub, av noo, thiab mechanical stress.
Kev ntsuas hluav taws xob:Txog li 1500V DC.
Flexibility:Tsim kom yooj yim rau nruab thiab taug kev.
Cov qauv zoo li H1Z2Z2-K thiab PV1-F xyuas kom cov hnub ci cables ua tau raws li kev ua tau zoo thiab kev nyab xeeb.
Nkag siab txog 4mm² thiab 6mm² Solar Cables
1. Hla-Sectional Area
Thawj qhov sib txawv ntawm 4mm² thiab 6mm² hnub ci cables nyob hauv lawv qhov chaw hla.
4mm :wb.Tus neeg xyuas pib thaj tsam yog 4 square millimeters.
6mm :wb.Tus neeg xyuas pib thaj tsam yog 6 square millimeters.
Qhov loj dua tus neeg xyuas pib ntawm 6mm² cable tso cai rau nws nqa tam sim no ntau dua li 4mm² cable, ua rau nws tsim nyog rau kev siv hluav taws xob ntau dua.
2. Tam sim no-Carrying Peev Xwm
Lub ampacity (qhov siab tshaj plaws tam sim no ib lub cable tuaj yeem nqa tau zoo) nyob ntawm cov khoom xws li cov khoom siv, kev teeb tsa, thiab qhov kub thiab txias.
| Cable Loj | Tam sim no muaj peev xwm (H1Z2Z2-K) | Tam sim no muaj peev xwm(PV1-F) |
|---|---|---|
| 4mm qw | Txog li 55A | Txog li 44A |
| 6mm 2 kwg | Txog li 70A | Mus txog 57A |
Qhov muaj peev xwm tam sim no ntawm 6mm² cables ua rau lawv zoo dua rau cov tshuab loj lossis cov xwm txheej uas tam sim no ntws siab.
3. Voltage poob
Voltage poob yog qhov tseem ceeb hauv kev teeb tsa hnub ci. Nws hais txog qhov poob ntawm qhov hluav taws xob thaum hluav taws xob taug kev los ntawm cable.
4mm² Hnub ci Cable:Muaj kev cuam tshuam ntau dua qhov kev poob qis dua qhov kev ncua ntev vim qhov me me ntawm tus neeg xyuas pib.
6mm² Hnub ci Cable:Kev paub txog kev poob qis qis, ua rau nws tsim nyog rau kev siv cable ntev dua.
Piv txwv li, ib lub kaw lus nrog 20-meter cable khiav yuav muaj qhov tsis zoo ntawm qhov hluav taws xob siv 4mm² cables tab sis tsawg kawg poob nrog 6mm² cables.
4. Hwj chim tuav peev xwm
Lub hwj chim (kW) lub hnub ci cable tuaj yeem ua haujlwm ntawm nws qhov ampacity thiab qhov system voltage:
Lub zog (kW) =V (V) × Tam sim no (A) ÷ 1000
| Cable Loj | Hauv 1000V DC | Hauv 500V DC |
|---|---|---|
| 4mm qw | 55 kW ib | 27.5 kWm |
| 6mm 2 kwg | 70 kW ib | 35 kW |
Rau cov tshuab uas xav tau kev hloov hluav taws xob ntau dua, 6mm² cables muaj txiaj ntsig zoo dua thiab muaj kev nyab xeeb dua.
5. Nyhav thiab Flexibility
4mm² Solar Cables:Lub teeb thiab hloov tau yooj yim, ua rau lawv yooj yim rau nruab thiab ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv cov kab ke.
6mm² Solar Cables:Hnyav thiab tsis yoog raws tab sis tsim nyog rau kev teeb tsa loj dua.
Daim ntawv thov ntawm 4mm² thiab 6mm² Solar Cables
4mm² Solar Cables
Residential Solar Systems:Haum rau me me mus rau nruab nrab-qhov loj me installation nrog luv cable khiav.
Cov ntawv thov tam sim no qis:Qhov zoo tshaj plaws rau cov tshuab uas tam sim no qis dua 55A thiab qhov hluav taws xob poob tsis yog qhov kev txhawj xeeb loj.
