Thaum tsim lub hnub ci photovoltaic (PV) system, kev xaiv ntawm cable loj yog qhov tseem ceeb. A1.5 mm² hnub ci cableFeem ntau siv rau hauv cov ntawv thov me me, tab sis nws lub peev xwm nyob ntawm ntau yam xws li tam sim no, qhov hluav taws xob, kev teeb tsa, thiab hom kab hluav taws xob uas nws ua raws, xws li H1Z2Z2-K lossis PV{{4} }F.
Kab lus no tshawb txog ntau npaum li cas lub zog ntawm 1.5 mm² hnub ci cable tuaj yeem ua raws li kilowatts (kW) thiab muab kev taw qhia txog thaum twg yuav siv nws hauv PV systems.
Cov yam ntxwv tseem ceeb ntawm 1.5 mm² Solar Cable
Ib tug 1.5 mm² cable muaj ib tug cross-sectional cheeb tsam ntawm 1.5 square millimeters. Qhov loj me me no ua rau nws lub teeb yuag, yoog raws, thiab tsim nyog rau kev siv hnub ci hluav taws xob tsawg.
Tam sim no-Carrying Peev Xwm
Lub peev xwm ntawm 1.5 mm² cable sib txawv nyob ntawm qhov kev teeb tsa:
Hauv Huab Cua Dawb:Lub cable muaj peev xwm nqa tau tam sim no txog li 15A txog 20A raws li qhov zoo tagnrho.
Hauv Conduits lossis Underground:Thaum tshav kub kub dissipation yog txo, txo lub peev xwm tam sim no rau ib ncig ntawm 12A txog 15A.
Kev ntsuas hluav taws xob
H1Z2Z2-K:Rated txog li 1.5 kV DC, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo hauv cov tshuab PV niaj hnub.
PV1-F:Rated txog li 1.0 kV DC, haum rau cov laus thiab cov ntawv siv hluav taws xob tsawg.
Environmental Resistance
UV thiab Ozone Resistance:Ua kom siv sab nraum zoov yam tsis muaj degradation.
Kev kub siab dav:Feem ntau ua haujlwm nruab nrab ntawm -40 degree mus rau +120 degree, ua kom muaj kev ua tau zoo hauv huab cua huab cua.
Xam Lub Zog Muaj Peev Xwm ntawm 1.5 mm² Solar Cable
Txhawm rau txiav txim siab ntau npaum li cas lub zog (hauv kW) 1.5 mm² cable tuaj yeem siv tau, siv cov qauv:
P=V×I
Qhov twg:
P=Lub zog (W)
V=Voltage (V)
Kuv=Tam sim no (A)
Piv txwv xam
Rau lub hnub ci kev ua haujlwm ntawm 12V thiab cable muaj peev xwm nqa 15A:
P=12 V×15 A=180 W
Yog tias qhov system ua haujlwm ntawm 48V:
P=48 V×15 A=720 W
Rau siab dua voltages xws li 600V, muaj nyob rau hauv coj mus muag PV systems:
P=600 V × 15 A=9, 000 W=9 kWP
Nco tseg:Lub peev xwm tiag tiag nyob ntawm qhov tshwj xeeb kev teeb tsa, cable ntev, thiab qhov tso cai qhov hluav taws xob poob.
Thaum twg koj tuaj yeem siv 1.5 mm² Solar Cable?
1. Low-Power Systems
Ib qho 1.5 mm² hnub ci cable yog tsim rau kev teeb tsa me me, xws li:
Kev teeb tsa hauv tsev nrog lub zog tso tawm qis dua 1 kW.
Off-grid daim ntaub ntawv zoo li lub hnub ci hluav taws xob teeb pom kev zoo lossis cov twj tso dej me me.
2. Luv Cable Runs
Vim nws muaj peev xwm tsawg, 1.5 mm² cable yog qhov zoo tagnrho rau kev ncua deb, feem ntau tsawg dua 10 meters. Kev khiav hauj lwm ntev tuaj yeem ua rau muaj qhov cuam tshuam loj heev, txo kev ua haujlwm.
3. Ua raws li Cov Qauv
Xyuas kom lub cable ua tau raws li H1Z2Z2-K lossis PV1-F cov qauv, uas lav:
Siab tiv taus UV thiab huab cua raug.
Halogen-dawb thiab nplaim-retardant zog rau kev ruaj ntseg.
Yam yuav tsum tau xav txog ua ntej siv 1.5 mm² Solar Cable
1. Voltage poob
Voltage poob nce nrog cable ntev thiab tsis kam. Nws raug nquahu kom khaws qhov voltage poob hauv qab no3%rau kev ua haujlwm zoo tshaj plaws.
Voltage poob tuaj yeem xam raws li:
Vdrop=I × R × L
Qhov twg:
R=Cable tsis kam ib 'meter' (Ω / m).
L=Tag nrho qhov ntev ntawm cable khiav (meters).
2. Qhov System Power Requirements
Tag nrho cov hluav taws xob tso tawm ntawm lub hnub ci vaj huam sib luag yuav tsum tsis pub dhau lub peev xwm ntawm cable. Piv txwv li, 1.5 mm² cable nqa 15A ntawm 48V tuaj yeem ua haujlwm txog 720W. Rau cov tshuab loj, xav txog kev kho dua tshiab rau 2.5 mm² lossis 4 mm² cable.
3. Ib puag ncig tej yam kev mob
Yog hais tias lub cable raug mob hnyav, xws li qhov kub thiab txias los yog ncaj qha tshav ntuj, nws lub peev xwm nqa tam sim no yuav txo qis. Cables ntsib H1Z2Z2-K thiab PV1-F cov qauv yog tsim los tiv thaiv cov teeb meem no.
4. Kev nthuav dav yav tom ntej
Yog tias koj npaj yuav nthuav koj lub hnub ci rau yav tom ntej, xav txog kev siv lub cable loj dua kom haum raws li qhov xav tau ntawm lub zog loj.
