Kub Dip Galvanized Steel rau Hnub Ci Mounting: Algeria Project Case Study for Harsh climates

Raws li Algeria cov khoom siv hluav taws xob thiab kev faib khoom PV nthuav dav sai, sib piv cov ntsiab lus ntawm galvanized steel rau cov chaw hauv cheeb tsam tau dhau los ua qhov tseem ceeb rau kev xa tawm 25+ xyoo kev pabcuam lub neej. Rov qab los ntawm 10 xyoo ntawm kev paub tshwj xeeb hauv kub -dip galvanized steel ntau lawm, Shandong Pinjie Cov Khoom Siv Tshiab tau taug qab kev xa tawm hnub ci hauv cheeb tsam ze. Cov ntaub ntawv kawm no rhuav tshem cov kev xaiv cov khoom siv rau sab saum toj Algerian tauj dua tshiab zog EPC's dual- qhov chaw siv hluav taws xob PV portfolio, muab cov ntaub ntawv siv tau rau cov phiaj xwm hnub ci thoob plaws North Africa thaj chaw huab cua hnyav.

EPC tau tsim ob hom phiaj xwm ib txhij, txhua tus muaj qhov tshwj xeeb ib puag ncig kev ntxhov siab uas cuam tshuam ncaj qha rau cov qauv hlau ua haujlwm.

Inland desert sites host av-mounted solar system deployments, whereas structural components fim txhua hnub kub viav vias ntawm 30-40 degree, nquag sandstorms, thiab sustained cua speeds mus txog 120km / h. Raws li ntug dej hiav txwv nroog, lub hnub ci vaj huam sib luag mounting system cuam tshuam nrog cov tshuaj ntsev tas li thiab ua kom cov av noo nyob ib puag ncig, ob qho tib si uas ua rau electrochemical corrosion ntawm cov hlau raug. Cov lus qhia dav dav hnub ci racking system tsis ua raws li cov xwm txheej sib txawv, ua rau cov txheej txheem ntxov ntxov thiab cov nqi hluav taws xob ntau dua.

Kev ua tau zoo ntawm qhov kub thiab txias yog ib qho ntawm thawj qhov kev tshuaj ntsuam xyuas rau txoj haujlwm xaiv cov khoom siv. Hnub nruab hnub kub hauv Algeria cov suab puam hauv av tsis tu ncua nce siab dua 55 degree, tom qab ntawd poob qis tom qab hnub poob. Qhov no rov ua kom thermal expansion thiab contraction ua rau ntau cov organic coatings tawg los yog delaminate nyob rau lub sij hawm, txiav txim tawm ntau lwm txheej txheej kev xaiv thaum ntxov ua hauj lwm.

Kub kub resistant solar racking designs ua rau kub-dip galvanized steel zam no hom tsis ua hauj lwm nkaus. Lub metallurgical daim ntawv cog lus ntawm zinc thiab hlau tseem nyob ruaj khov nyob rau hauv ib tug dav heev kub ntau yam, thiab txheej txheej nyob twj ywm raws li nyob rau hauv lub thickness thiab muaj pes tsawg leeg yuav tsum tau teev tseg nyob rau hauv ASTM A123 thiab ISO 1461 nyob rau hauv raug suab puam kev khiav hauj lwm tej yam kev mob. Qhov kev ruaj ntseg thermal no tshem tawm txoj kev pheej hmoo ntawm txheej txheej delamination los ntawm kev kub ntxhov ntawm cyclic.

Tshaj li thermal stability, zinc-hlau alloy txheej tsim thaum lub sij hawm galvanizing txheej txheem sau npe nyuaj dua li lub hauv paus steel nws tus kheej, uas txhim kho kev tiv thaiv rau abrasion los ntawm cua-blown xuab zeb - ib qho tseem ceeb kev ua tau zoo ntawm cov chaw suab puam. Rau faus hauv paus seem, luam tawm cov ntaub ntawv teb los ntawm cov dej khov zoo sib xws- cov haujlwm hauv cheeb tsam qhia tau hais tias cov hlau galvanized muaj 3-6 npaug qis dua qhov nruab nrab corrosion ntau dua li cov hlau tsis muaj coated, txo qhov ntev - lub sij hawm tu thiab hloov cov nqi nyob rau tag nrho cov phiaj xwm lifecycle. Rau cov chaw ntug dej hiav txwv, kub-dip galvanized steel muab qhov kev tiv thaiv kev tiv thaiv los ntawm ntsev{10}}induced corrosion; thaum ua ke nrog kev tswj cov txheej txheem sib xws thiab ua kom zoo zinc txheej tuab, nws muab kev ua haujlwm txhim khu kev qha nyob rau hauv siab - av noo, ntsev - tshuaj tsuag ib puag ncig.

Peb tag nrho ntawmkub dip galvanized hnub ci mountingcov khoom txhawb nqa cov txheej txheem txheej txheem raws li cov ntug dej hiav txwv, suab puam, thiab kev sib xyaw huab cua hnub ci ua haujlwm thoob plaws North Africa.

Pab pawg ua haujlwm tau kho cov khoom tshwj xeeb nyias nyias rau txhua qhov chaw, tsis yog siv ib qho -loj- haum- txhua tus qauv thoob plaws ob qhov chaw. Txoj hauv kev sib tw no muab cov phiaj xwm ua kom ruaj khov yam tsis tau ntxiv cov nqi them ua ntej.

Table 1. Txheem vs. Algeria-Optimized Galvanized Steel Solar Mounting Specifications

Rau cov PV mounting qauv ntawm inland suab puam qhov chaw, cov specification siv Q355B siab-lub zog qis- alloy steel puag cov ntaub ntawv nrog ib tug nruab nrab zinc txheej ntawm 75-85μm, ua ke nrog reinforced profile qhov ntev los txhawb 120km / h hauv zos cua loads. Rau cov chaw ntug dej hiav txwv, txheej txheej txheej thiab kev tswj kom tsis sib xws yog nruj kom xa cov 85-100μm zinc txheej, txhim kho ntsev corrosion kom ua tau raws li 25+ xyoo tsim kev pabcuam lub neej. Lub optimized profile geometry kuj txhawb kev tsim qauv, uas txo qis kev ua haujlwm thiab ntawm - lub sijhawm teeb tsa ntawm qhov chaw kwv yees li 20%.

Txoj hauv kev zoo li no rau kev xaiv cov khoom siv tau dhau los ua ntau dua thoob plaws hauv cheeb tsam, vim tias cov txheej txheem hnub ci racking qhov tshwj xeeb tsis tuaj yeem xa cov kev ua tau zoo nyob thoob plaws ntau yam ntawm North African qhov chaw.

Kev sib txuam txheej tuab thiab cov khoom siv hauv paus qib rau cov huab cua hauv cheeb tsam thiab cov av hauv cheeb tsam muab cov txiaj ntsig zoo dua - lub sij hawm tus nqi, yam tsis tau ntxiv cov nqi them ua ntej. Rau cov pab pawg EPC, txheeb xyuas cov txheej txheej tuab, ruaj khov cov khoom siv kho tshuab, thiab kev tswj xyuas cov khoom tsim tau zoo yog txhua kauj ruam tseem ceeb thaum ntsuas cov khoom siv.

Nrog 10 xyoo ntawm kev tsom mus rau galvanized steel rau hnub ci kev siv cov qauv, Shandong Pinjie Cov Khoom Tshiab tsim cov txheej txheem txheej txheem kom haum rau ib puag ncig sib txawv. Peb ua haujlwm ncaj qha nrog pab pawg ua haujlwm txhawm rau ua kom cov khoom tsis sib xws nrog cov ntaub ntawv tshwj xeeb ntawm qhov chaw, thiab peb cov kev tswj hwm kev tsim khoom tau ua tiav raws li cov kev ntsuas cuam tshuam thiab kev ua tau zoo ntawm cov qauv kev lag luam thoob ntiaj teb.

Rau cov pab pawg EPC thiab cov neeg tsim khoom ua haujlwm ntawm Algerian lossis North African hnub ci cov phiaj xwm, peb pab pawg kws tshaj lij tuaj yeem muab qhov chaw -cov ntaub ntawv tshwj xeeb muab cov kev daws teeb meem thiab thib peb-cov ntaub ntawv txheej txheem txheej txheem. Thov ibcustomized khoom specification daim ntawvlos yogtiv tauj peb pab neeg txhawb nqa qhov projecttxhawm rau txhim kho koj cov khoom xaiv nrog cov huab cua hauv zos.

Raws li kev xa tawm hnub ci txuas ntxiv mus nrawm thoob plaws North Africa, peb yuav ua kom zoo dua peb cov khoom tsim los pab cov neeg siv khoom tsim kom ruaj khov, tus nqi - siv lub hnub ci zoo.
