Thaum nws los txog rau hnub ci vaj huam sib luag, hom cable koj siv yog ib qho tseem ceeb xws li cov panels lawv tus kheej. Txoj cai cable ua kom zoo tshaj plaws, kev nyab xeeb thiab kav ntev ntawm koj lub hnub ci.

Taw qhia rau cov khoom siv photovoltaic cables

Photovoltaic cable yog ib lub cable tshwj xeeb uas tsim los rau lub hnub ci vaj huam sib luag, nrog rau qhov kub thiab txias, tiv thaiv UV, kev hloov pauv huab cua thiab lwm yam ntxwv. Cov hauv qab no yog ob peb hom photovoltaic cables:
Ib leeg-ntxhais photovoltaic cable feem ntau yog siv los txuas cov hnub ci vaj huam sib luag thiab cov thawv sib txuas, nrog cov huab cua tsis zoo thiab kev puas tsuaj. Dual-core photovoltaic cable yog siv rau kev sib txuas lossis kev sib txuas ntawm cov hnub ci vaj huam sib luag, muab kev ntseeg siab dua thiab kev nyab xeeb.

Yam tseem ceeb uas yuav tsum tau xav txog thaum siv cables rau hnub ci vaj huam sib luag

Yuav pib nrog, koj yuav tsum tau ua ntej siv cov cables uas tsim tshwj xeeb rau kev siv hnub ci. Cov cables no feem ntau sau tias "PV cables" thiab muaj cov khoom uas zoo tagnrho rau kev nqa hluav taws xob los ntawm lub hnub ci vaj huam sib luag. Lawv tau tsim kom ntev dua thiab tiv taus ib puag ncig hnyav xws li hnub ci, cua, nag thiab huab cua kub.

Lwm qhov kev txiav txim siab tseem ceeb thaum xaiv cov cables rau hnub ci vaj huam sib luag yog qhov loj ntawm tus neeg xyuas pib. Tus neeg xyuas pib yog dab tsi nqa lub zog hluav taws xob los ntawm lub hnub ci vaj huam sib luag mus rau inverter. Cov kab hluav taws xob loj loj yuav muaj qhov ua haujlwm qis dua thiab kev ua haujlwm siab dua, uas yog qhov tseem ceeb rau kev ua kom lub zog tso zis ntawm koj lub hnub ci siab tshaj plaws.

Koj yuav tsum tau them sai sai rau lub rwb thaiv tsev cable. Nws yuav tsum tau ua los ntawm cov ntaub ntawv uas tuaj yeem tiv taus UV hluav taws xob thiab kub kub yam tsis muaj degrading lossis melting. Cov khoom siv rwb thaiv tsev zoo tshaj plaws yog cross-linked polyethylene, uas muaj kev tiv thaiv ib puag ncig thiab tuaj yeem tiv thaiv cable los ntawm kev puas tsuaj rau lub cev.

Thaum kawg, thaum xaiv lub hnub ci vaj huam sib luag cable, xyuas kom meej tias nws raug ntsuas rau tib qhov hluav taws xob raws li lub hnub ci vaj huam sib luag lawv tus kheej. Qhov no yog ib qho tseem ceeb los tiv thaiv tej yam xwm txheej hluav taws xob.

Los ntawm kev noj cov khoom no rau hauv tus account, koj tuaj yeem xyuas kom meej tias koj xaiv qhov zoo tshaj plaws cable rau koj lub hnub ci vaj huam sib luag. Txoj cai cable yuav tsis tsuas yog xyuas kom meej tias koj tau txais txiaj ntsig zoo tshaj plaws ntawm koj lub hnub ci tab sis kuj xyuas kom meej tias nws kav ntau xyoo.

Cable installation thiab tu

PV cables yuav tsum tau muab ntsia raws li cov lus qhia tshwj xeeb, zam kev khoov ntau dhau, tuav lub vojvoog khoov kom tsim nyog, thiab xyuas kom meej tias tus neeg xyuas pib thiab txheej txheej rwb thaiv tsev tsis puas. Cov tsos ntawm lub cable yuav tsum tau kuaj xyuas tsis tu ncua kom ntseeg tau tias tsis muaj kev laus, kev puas tsuaj lossis overheating. Txheeb xyuas cov ntsiab lus sib txuas thiab ua haujlwm tsis tu ncua kom ntseeg tau tias kev sib txuas ruaj khov thiab tsis xoob lossis corroded.

Specification xaiv thiab cov yam ntxwv ntawm cable

Qhov tsim nyog cable cross-sectional cheeb tsam tuaj yeem xaiv raws li qhov loj ntawm qhov system tam sim no. Feem ntau photovoltaic cable cross-sectional thaj chaw muaj xws li 4mm², 6mm², 10mm², thiab lwm yam. Qhov loj dua ntawm lub cable cross-sectional cheeb tsam, qhov ntau dua tam sim no nws nqa tau, thiab qhov qis dua, txo qis zog. Photovoltaic cables feem ntau yog tsim los rau DC high voltage ib puag ncig, thiab cov rated voltages feem ntau yog 600V, 1000V, 1500V, thiab lwm yam. Xaiv cable specifications haum rau qhov system voltage kom muaj kev ruaj ntseg thiab efficiency.

Cov kab hluav taws xob photovoltaic yuav tsum muaj peev xwm tiv taus qhov kub thiab txias, feem ntau ntawm -40 degree thiab +90 degree , thiab qee qhov kev ua tau zoo cables tuaj yeem tiv taus qhov kub siab dua. Txij li cov hnub ci vaj huam sib luag feem ntau raug rau sab nraum zoov ib puag ncig, cables yuav tsum muaj huab cua tiv thaiv zoo heev thiab UV tiv thaiv kom ntseeg tau tias lawv yuav tsis muaj hnub nyoog lossis kev ua haujlwm tsis zoo tom qab raug tshav ntuj ntev.

Cable ntawv pov thawj thiab cov qauv

1. Cov ntawv pov thawj thoob ntiaj teb suav nrog TÜV daim ntawv pov thawj, ib daim ntawv pov thawj muaj nyob hauv European lag luam, kom ntseeg tau tias cov cable ua tau raws li cov qauv kev nyab xeeb thoob ntiaj teb. UL daim ntawv pov thawj, ib daim ntawv pov thawj muaj nyob rau hauv North American lag luam, xyuas kom meej tias cov cable ua tau raws li North American cov qauv kev nyab xeeb.
2. Kev ua raws li cov qauv xws li IEC 62930, International Electrotechnical Commission (IEC) tus qauv rau cov kab hluav taws xob photovoltaic, qhia txog kev ua haujlwm ntawm cov cables. TS EN 50618 Cov txheej txheem European rau photovoltaic cables ntsuas ntawm 1.5kV DC
