Qhov kom zoo dua ntawm cov pa luam yeeb tsawg xoom halogen (LSZH) cov khoom siv cable
Low Smoke Zero Halogen (LSZH) cov khoom siv cable yog cov khoom siv insulating thiab sheathing siv hauv kev tsim cov cables rau ntau yam kev siv. LSZH cables yog tsim los tso pa tawm tsawg kawg yog thaum muaj hluav taws kub thiab tsis tsim cov pa phem, ua rau lawv zoo tagnrho rau siv hauv qhov chaw kaw lossis qhov cua tsis zoo.
Kev thov rau LSZH cov ntaub ntawv cable tau nce zuj zus nyob rau xyoo tas los no vim muaj kev paub txog kev noj qab haus huv uas muaj feem cuam tshuam nrog kev siv cov kab hluav taws xob PVC. Txhawm rau ua kom tau raws li qhov xav tau loj hlob no, cov tuam ntxhab tau nqis peev hauv kev tsim cov khoom siv hluav taws xob tsawg tsawg, halogen-free cable uas tsis tsuas yog ua tau raws li cov qauv kev nyab xeeb nruj tab sis kuj muab kev ua tau zoo thiab ua haujlwm ntev.
Ib qho ntawm qhov zoo ntawm LSZH cable cov ntaub ntawv yog txo kev cuam tshuam ib puag ncig. Tsis zoo li cov kab hluav taws xob PVC ib txwm muaj, uas tso cov tshuaj tsis zoo rau hauv ib puag ncig thaum tsim khoom thiab pov tseg, cov kab hluav taws xob tsis muaj halogen tsawg yog tsim los ntawm cov thermoplastic tebchaw uas tsis muaj halogens thiab lwm yam tshuaj lom. Qhov no ua rau cov kab hluav taws xob tsis tshua muaj pa halogen tsis muaj kev xaiv zoo dua thiab ib puag ncig zoo rau kev tsim kho niaj hnub thiab kev tsim kho vaj tse.
Ntxiv rau cov txiaj ntsig ib puag ncig, cov pa hluav taws xob tsis muaj halogen tsis muaj hluav taws xob kuj tseem paub txog lawv cov khoom siv hluav taws xob zoo heev. Thaum raug kub hnyiab, tsoos PVC cables tuaj yeem tso cov pa phem thiab cov pa luam yeeb, ua rau muaj kev hem thawj rau tib neeg thiab khoom. Tsis tshua muaj pa halogen-dawb cables, ntawm qhov tod tes, yog tsim los tiv thaiv kev sib kis ntawm hluav taws thiab txo qis kev tso tawm cov khoom tsis zoo, muab kev nyab xeeb ua haujlwm thiab nyob ib puag ncig rau txhua tus.
Tsis tas li ntawd, LSZH cables muaj kev tiv thaiv ntau dua rau kev puas tsuaj, ya raws thiab qhov kub thiab txias, ua rau lawv haum rau ntau yam kev siv sab hauv tsev thiab sab nraum zoov. Los ntawm ib puag ncig kev lag luam mus rau cov tsev nyob, cov kab hluav taws xob tsis muaj pa halogen tsis tshua muaj kev ntseeg siab thiab muaj txiaj ntsig zoo rau kev siv hluav taws xob thiab kev sib txuas lus.
Raws li qhov kev thov rau cov khoom siv hluav taws xob tsis tshua muaj pa taws thiab halogen-dawb txuas ntxiv mus ntxiv, ntau yam khoom siv hluav taws xob tsis muaj pa taws thiab halogen-free cable ntawm kev ua lag luam xav kom nthuav dav ntxiv. Cov neeg tsim khoom txuas ntxiv mus tshawb fawb thiab tsim cov qauv tshiab thiab cov txheej txheem tsim khoom los txhim kho kev ua tau zoo thiab kev ua tau zoo ntawm LSZH cables, kom ntseeg tau tias lawv tseem muaj lwm txoj hauv kev rau cov tsoos PVC cables.
Hauv cov ntsiab lus, qhov nce ntxiv ntawm cov pa luam yeeb tsawg, halogen-dawb cable cov ntaub ntawv sawv cev rau kev hloov pauv tseem ceeb rau kev nyab xeeb thiab kev daws teeb meem ntau dua. Tsis tshua muaj pa halogen-free cables yuav ua lub luag haujlwm tseem ceeb hauv lub neej yav tom ntej ntawm kev lag luam cable nrog lawv cov hluav taws kub zoo, cov txiaj ntsig ib puag ncig thiab kev siv ntau yam. Raws li kev ua lag luam rau cov khoom siv hluav taws xob tsawg thiab tsis muaj halogen txuas ntxiv nthuav dav, nws yog qhov tseeb tias cov khoom siv hluav taws xob tsawg thiab halogen-free cables nyob ntawm no.
