Ingcaciso yeMveliso

Njengomvelisi oyingcali, singathanda ukukubonelela ngePaidu UL 4703 Photovoltaic PV Cable. I-UL 4703 isemgangathweni ye-Photovoltaic (PV) yocingo. Ichaza iimfuno zocingo lwe-PV ye-conductor enye enikwe i-2000 V okanye ngaphantsi, kunye ne-90 ° C emanzi okanye eyomileyo. Ucingo luqhele ukusetyenziselwa ukudityaniswa kwee-wiring zeenkqubo zamandla e-photovoltaic ezisekelwe phantsi kunye nezingafakwanga. Intambo iqulathe i-conductor exineneyo yobhedu, ukugqunywa kwe-PVC, kunye nebhatyi ye-PVC ekwaziyo ukumelana nokukhanya kwelanga. Olu hlobo lwentambo lukhusela ekufuma, ekukhanyeni kwelanga, nakwimikrwelo enokwenzeka. Iimpawu eziphambili kunye neengqwalasela ezinxulumene ne-UL 4703 Photovoltaic PV Cable ziquka:

Uyilo lweNkokeli eNye-engundoqo enye:Iintambo ze-UL 4703 zePV zikholisa ukuba ziintambo ezingundoqo zomdibaniso omnye ezineconductor yobhedu egqunyiweyo kunye nesheathed.

Izinto zokugquma:I-insulation ye-cable, ehlala yenziwe nge-polyethylene edibeneyo (i-XLPE), ibonelela ngombane kwaye ikhusela kwizinto ezisingqongileyo.

Isixhobo seSheath:Ibhatyi yangaphandle yentambo idlala indima ebalulekileyo ekuyikhuseleni ekukhanyeni kwelanga, ukuhluka kobushushu, ukufuma kunye nezinye iimeko zokusingqongileyo. Izinto ezihlala ixesha elide kunye ne-UV-resistant zisetyenziswa ngokuqhelekileyo kwijacket, ziqinisekisa ubude bentambo kunye nokuthembeka.

Uqondo lobushushu:Iintambo ze-UL 4703 ze-PV kufuneka zihlangabezane neereyithingi ezithile zobushushu kuzo zombini ubushushu obuphezulu bokusebenza komqhubi kunye nentambo iyonke. Ezi zilinganiso ziqinisekisa ukusebenza okukhuselekileyo phantsi kweemeko eziqhelekileyo ezidibana nofakelo lwelanga.

Ukumelana nokukhanya kwelanga:Ijacket yekhebula yenzelwe ukuxhathisa imiphumo ephazamisayo yokukhanya kwelanga ixesha elide, iqinisekisa ukuqina kwayo kunye nokusebenza kwayo ngexesha.

Ukuba bhetyebhetye:Nangona iintambo ze-PV zihlala zifakwe kwindawo esisigxina ngaphakathi kweepaneli zelanga, kufuneka zibe nokuguquguquka okwaneleyo ukulungiselela ukufakwa kunye nokuhamba okunokwenzeka ngaphakathi kwenkqubo.

Ukuthobela:Isatifikethi se-UL 4703 siqinisekisa ukuba intambo ye-PV ihlangabezana nemigangatho ethile yokhuseleko kunye nokusebenza. Ukuthotyelwa kwemigangatho ye-UL kudla ngokuba yimfuneko yokusetyenziswa kwentambo yePV kwiiprojekthi ezahlukeneyo zelanga.
