Nrog kev nrawm nrawm ntawm ntiaj teb hluav taws xob hloov, Hnub ci photovoltaic (PV) lub zog hluav taws xob tau dhau los ua ib qho tseem ceeb tshaj plaws ntawm kev huv thiab txuas ntxiv dua. Hauv North America, South America, Tebchaws Middle East, thiab Southeast Asia, PV fais fab nroj tsuag tau tsim ntawm qhov tsis muaj kev tiv thaiv. Nyob rau tib lub sijhawm, cov cai rau cov tshuab hluav taws xob-} Tshwj xeeb}}} yog ua ntau txoj hlua khi.
PV nroj tsuag muaj kev ua haujlwm nyob rau hauv cov xwm txheej hnyav: huab cua sov nyob rau hauv cov ntug hiav txwv huab, lossis ntev raug rau muaj zog ultraviolet hluav taws xob. Nyob rau hauv xws li ib puag ncig yuav tsum witand siab, UV hluav taws xob, noo noo, thiab tshuaj lom neeg kev nyab xeeb, thaum ntev} lub sij hawm ruaj khov.
Ntawm ntau cov PV cable,RHW-2 CableTau dhau los ua kev xaiv dav dav, tshwj xeeb tshaj yog nyob rau hauv loj- nplai hauv paus pv fais fab nroj tsuag, ua tsaug rau nws cov qauv kev ntseeg tau thiab kev ua haujlwm zoo dua. This article provides a detailed analysis of the advantages of RHW-2 cables in PV applications, along with a comparison to XHHW-2 cables, offering valuable technical insight for system designers, contractors, and procurement professionals.
Cov yam ntxwv thiab cov txiaj ntsig ntawmRHW-2 Cable
Cov qauv thiab cov qauv
RHW-2 Cable yog insulated nrogHla - Txuas Polyethylene (XLPE), cov khoom siv hu ua cov rwb thaiv tsev hluav taws xob thiab lub zog kho tshuab. Cov tsiaj ntawv "Rhw" sawv rauTiv taus cua sov thiab dej, thaum lub "2" qhia tias nws tuaj yeem ua haujlwm tsis tu ncua ntawm90℃nyob rau hauv ob qho chaw ntub thiab qhuav.
Cov Kev Tshaj Tawm Tseem Ceeb:
- Cov Ntsuas Hluav Taws Xob: 600V
- Qhov Ntsuas Kub: 90℃(haum rau ob qho chaw ntub thiab qhuav)
- Rwb thaiv tsev ntaub: XLPE, muab lub zog ua kom zoo thiab muaj zog thiab zoo heev thermal ruaj khov
- Txoj kev teeb tsa: Haum rau kev faus neeg ncaj qha, conduit teeb meem, thiab kis sab nraum zoov
- Daim ntawv muaj cai: Tag nrho ua raws nrogUL Qauv, kom muaj kev nyab xeeb thiab kev ntseeg tau rau North American lag luam
RhW-2 Cable yog tsim los tiv thaiv kev nyuaj rau ib puag ncig ib puag ncig lub zog thaum ua rau lub zog muaj kev nyab xeeb thiab muaj txiaj ntsig zoo rau PV tshuab.
Cov lus qhia tshwj xeeb ntawm RHW-2 Cable
Txhawm rau kom tau raws li cov kev xav tau ntawm PV cov phiaj xwm, RHW-2 cov cable yog tsim nyob rau ntau qhov ntau thiab tsawg. Cov hauv qab no nthuav ntau seem thiab lawv cov yam ntxwv yooj yim.
