Dab tsi yog photovoltaic cables?

Photovoltaic (PV) cablesyog cov khoom siv hluav taws xob tshwj xeeb siv hauv cov tshuab hluav taws xob photovoltaic rau kev xa hluav taws xob hluav taws xob. Cov kab hluav taws xob no yog tsim los txuas cov hnub ci vaj huam sib luag (photovoltaic modules) rau lwm cov khoom ntawm lub hnub ci zog, xws li inverters, chargers, thiab roj teeb cia units. Nov yog qee cov yam ntxwv tseem ceeb thiab cov ntsiab lus ntawm PV cables:

Yam ntxwv ntawmPhotovoltaic Cables

High UV thiab huab cua tsis kam:

PV cables raug rau cov ntsiab lus, yog li lawv yuav tsum tiv taus ultraviolet (UV) hluav taws xob thiab huab cua hnyav. Qhov no ua kom lawv tswj tau lawv txoj kev ncaj ncees thiab kev ua haujlwm tau ntau xyoo ntawm kev siv sab nraum zoov.

Durability:

Cov cables no yog tsim los tiv thaiv kev ntxhov siab ntawm lub cev xws li kev puas tsuaj, khoov, thiab kev cuam tshuam txhua yam. Qhov kev ua haujlwm ntev no yog qhov tseem ceeb rau kev teeb tsa ntawm lub ru tsev, hnub ci ua liaj ua teb, lossis lwm qhov chaw uas cov cables yuav raug txav los yog kev ntxhov siab.

Kub Tolerance:

PV cables yuav tsum ua haujlwm zoo tshaj qhov kub ntawm qhov dav, feem ntau ntawm -40 ° C txog + 90 ° C lossis siab dua. Qhov no ua kom lawv tuaj yeem ua haujlwm tau zoo hauv ntau qhov kev nyab xeeb thiab huab cua huab cua.

Insulation thiab Sheathing:

Cov rwb thaiv tsev thiab txheej txheej ntawm PV cables feem ntau yog tsim los ntawm kev sib txuas ntawm polyethylene (XLPE) lossis ethylene propylene roj hmab (EPR). Cov ntaub ntawv no muab cov hluav taws xob rwb thaiv tsev zoo heev, thermal stability, thiab tshuaj tiv thaiv.

Tsawg Haus luam yeeb, Halogen-Free (LSHF):

NtauPV cablesyog tsim los kom muaj pa taws tsawg thiab tsis muaj halogen, uas txhais tau hais tias lawv tawm cov pa taws tsawg thiab tsis muaj cov pa phem halogen yog tias lawv ntes hluav taws. Qhov no txhim kho kev nyab xeeb, tshwj xeeb tshaj yog nyob rau hauv cov tsev nyob lossis kev lag luam teeb tsa.

High Voltage thiab tam sim no muaj peev xwm:

PV cables yog tsim los tswj cov high voltage thiab tam sim no generated los ntawm solar panels. Lawv feem ntau muaj qhov ntsuas hluav taws xob ntawm 600/1000V AC lossis 1000/1500V DC.
