Qhov tseeb, cov kab ke hnub ci feem ntau siv nyob rau hauv ib puag ncig ib puag ncig hnyav, lub hnub ci cable xws li siab kub thiab ultraviolet hluav taws xob. Hauv Tebchaws Europe, cov hnub tshav ntuj yuav ua rau thaj teb ntawm lub hnub ci mus txog 100 ° C. Txog tam sim no, hnub ci cable peb tuaj yeem siv ntau yam ntaub ntawv suav nrog PVC, roj hmab, hnub ci cable TPE thiab cov khoom siv sib txuas zoo sib txuas, tab sis hmoov tsis, roj hmab cov kab hluav taws xob nrog qhov ntsuas kub ntawm 90 ° C, hnub ci cable thiab txawm tias PVC cable nrog qhov ntsuas qhov kub thiab txias ntawm 70 ° C Nws tseem feem ntau siv sab nraum zoov, hnub ci cable pom tseeb, qhov no yuav cuam tshuam loj heev rau kev pab cuam lub neej ntawm lub system.
Kev tsim cov kab hluav taws xob hnub ci no muaj keeb kwm ntau dua 20 xyoo. Cov khoom siv hnub ci European siv cov hlua hluav taws xob no tau siv ntau dua 20 xyoo thiab tseem ua haujlwm zoo. Ib puag ncig kev ntxhov siab Raws li cov ntawv thov photovoltaic muaj kev txhawj xeeb, hnub ci cable cov ntaub ntawv siv sab nraum zoov yuav tsum txiav txim siab raws li lub teeb ci ultraviolet, ozone, hnub ci cable hloov pauv kub thiab tshuaj lom neeg yaig. Siv cov khoom ntim qis raws li qhov kev cuam tshuam zoo ntawm ib puag ncig no yuav ua rau lub sheath cable tsis muaj qhov tsis zoo thiab txawm tias rhuav tshem ntawm txheej rwb thaiv tsev cable. Tag nrho cov xwm txheej no yuav ncaj qha ua rau poob ntawm qhov cable hluav taws xob, hnub ci cable thiab tib lub sijhawm txoj kev pheej hmoo ntawm cable luv Circuit Court yuav nce ntxiv. Hauv nruab nrab thiab lub sijhawm ntev, hnub ci cable cov hluav taws lossis kev raug mob ntawm tus kheej tseem ntau dua.
