6.Cov xwm txheej nrog RHW-2 Cable:Rhw - 2 feem ntau siv rau kev tsim lossis kev faib khoom siv hluav taws xob thiab muaj tsawg uv thiab cua sov ua kom tsis taus. Ntev -} sij hawm} ntu sab nraum zoov kis tuaj yeem ua rau lub tsho laus laus, nce tus nqi kho thiab txaus ntshai. UL 4703 tau tsim tshwj xeeb rau PV-sab app, muab cov huab cua zoo tsis kam, nyiaj txiag, thiab kev nyab xeeb.
Cov ntawv thov raug cai ntawm ul 4703 hauv PV nroj tsuag
1.DC {{- sab txuas los ntawm cov modules rau inverters
DC Cables yuav tsum tau tiv nrog kev dav dav siab. UL 4703 muab cov haujlwm ruaj khov nyob rau hauv lub dc voltage, tsawg zog poob thiab kev nyab xeeb kev txaus ntshai.
2. Koj txhais tes hluav taws xob ntawm cov thawv sib txuas
Kev hloov pauv siab ua rau kev teeb tsa yooj yim hauv qhov chaw kaw, txo cov tshuab kev ntxhov siab ntawm pob qij txha thiab cov nqi tsis zoo.
3.Outdoor overhead cabling
Zoo heev UV thiab cua sov kuj tso cai ul 4703 kom walland ntev -}} tsis muaj kev ua haujlwm sab nraum zoov.
4.Direct faus faus (cov qauv tshwj xeeb)
Qee qib 4703 yog qhov tsim nyog rau kev sib nraus ncaj qha, tab sis nruj nreem ua kom cov txheej txheem tsim khoom lag luam.
Cov Tswv Yim Ua Haujlwm:Rau cov dc cable ntev khiav, kev saib xyuas tsawg dua khoov hluav taws xob, tam sim no, thiab voltage tso kom tsis txhob rwb thaiv los ntawm kev siv rwb.
