Raws li lub zog hluav taws xob hloov pauv, lub photovoltaic (PV) kev lag luam yog kev loj hlob sai heev. Tshwj xeeb, Asmeskas kev lag luam tau pom qhov kev tawm hauv lub voj solar, faib cov PV, thiab hluav taws xob- nplai hnub ci hluav taws xob nroj tsuag. Lub inverter, feem ntau hu ua "lub siab" ntawm PV system, plays lub luag haujlwm PV system, dc) rau lwm qhov tam sim no (AC) thiab ua kom muaj kev ruaj khov thiab ua haujlwm ntawm lub system. Hauv cov txheej txheem no, kev xaiv ntawm wiring cable ua ib qho kev txiav txim siab hauv qhov kev nyab xeeb thiab kev ua tau zoo.
Rau inverter xaim, cables yuav tsum tau txais cov kev pab, suav nrog cov khoom siv kub, muaj zog ultraviolet (ruaj nras tam sim no kev ua haujlwm. Ntawm cov kev xaiv muaj,Xhhw-2 CableTau dhau los ua ib qho kev xaiv tshwj xeeb tshaj plaws vim nws cov hluav taws xob zoo nkauj, huab cua zoo dua, thiab lub neej ntev.
Kab lus no muab cov lus qhia thoob plaws rauXHHW-2 Cable wiring specifications rau photovoltaic invererers, npog nws cov txuj ci ua, inverter wiring yuav tsum tau, cov qauv kev qhia tshwj xeeb, sib piv nrog siv cov kev txiav txim siab, thiab cov khoom lag luam zoo. Nws yog npaj los txhawb cov engineers, cov phiaj xwm ua haujlwm, thiab cov kws tshaj lij kev xaiv tsa hauv kev xaiv rau hnub ci hluav taws xob.
Txheej txheem cej luam ntawmXhhw-2 Cable
XHHW-2 Cable?
Xhhw -} 2 yog ul- Tau lees paub cov cable sib txuas nrog polyethylene (xlpe). Nws yog dav siv nyob rau hauv hnub ci, fais fab faib, lag luam vaj tse, thiab kev sib sau ua ke. Lub npe tau hais txog nws cov yam ntxwv):
