Hluav taws kub-Resistant Cables thiab Fire-Resistance Duration
Raws li lub npe txhais tau hais tias, hluav taws kub- cov kab hluav taws xob tiv taus yog tsim los tiv thaiv cov nplaim taws thiab tswj cov hluav taws xob txuas mus ntxiv rau ib lub sijhawm tshwj xeeb. Cov kab hluav taws xob no feem ntau yog siv rau hauv qhov chaw uas xav tau kev nyab xeeb hluav taws kub siab, xws li siab - cov tsev nce siab, subways, thiab fais fab nroj tsuag. "Fire-lub sijhawm tiv thaiv" yog hais txog lub sijhawm siab tshaj plaws uas lub cable tuaj yeem txuas ntxiv ua haujlwm ib txwm thaum raug nplaim taws. Qhov no yog ib qho kev ntsuas kev ua haujlwm tseem ceeb, feem ntau txhais los ntawm lub teb chaws lossis cov qauv kev lag luam.
Hluav taws kub-Resistance Capabilities ntawm Standard Cables
Raws li cov qauv hauv Suav teb, qhov hluav taws kub -kev tiv thaiv ntev rau cov qauv hluav taws kub- cov kab hluav taws xob tiv thaiv yuav tsum yog tsawg kawg 90 feeb. Qhov no txhais tau hais tias nyob rau hauv cov txheej txheem kev ntsuas nplaim hluav taws xob, lub cable yuav tsum tswj cov hluav taws xob ib txwm txuas ntxiv rau yam tsawg kawg ntawm 90 feeb yam tsis muaj kev cuam tshuam xws li luv luv lossis qhib circuits. Txawm li cas los xij, siab -kev ua tau zoo hluav taws xob- cov kab hluav taws xob tiv taus kuj muaj nyob hauv khw, muaj peev xwm tiv taus hluav taws rau 120 feeb lossis ntev dua. Cov kab hluav taws xob no feem ntau siv cov khoom tshwj xeeb thiab cov qauv tsim los txhim kho lawv cov hluav taws kub{10}} ua haujlwm tiv thaiv.
Puas yog Hluav Taws-Resistance Duration ntawm 180 Minutes Li qub?
Cov lus teb yog yog. Txawm hais tias lub sij hawm tus qauv rau hluav taws kub zoo tib yam- cov kab hluav taws xob tiv taus yog 90 feeb, qhov no tsis txwv qhov muaj nyob ntawm cov khoom siv hluav taws kub ntev dua - kev ntsuas ntsuas. Qhov tseeb, ua tsaug rau kev txhim kho thev naus laus zis thiab cov khoom siv tshiab, qee qhov siab -kev ua haujlwm cables tuaj yeem ua tiav- lossis txawm ntau dua - hluav taws kub - ua haujlwm ntev li 180 feeb. Cov kab hluav taws xob zoo li no feem ntau yog siv rau hauv ib puag ncig uas muaj kev ruaj ntseg hluav taws kub heev, xws li nuclear fais fab nroj tsuag thiab petrochemical chaw. Yog li, yog tias hluav taws kub- tiv thaiv cable thov qhov ntsuas 180-feeb thiab tau txais kev txhawb nqa los ntawm cov ntawv ceeb toom thiab cov ntawv pov thawj cuam tshuam, nws yog qhov qub tag nrho.
Cov lus pom zoo rau kev xaiv thiab thov
Thaum xaiv cov hluav taws kub- cov kab hluav taws xob tiv taus, ib qho yuav tsum xav txog yam tshaj li qhov hluav taws kub xwb -lub sij hawm tsis kam- xws li cov khoom siv hluav taws xob, rwb thaiv tsev, sheathing, thiab cov qauv tsim. Cov ntsiab lus no txhua tus cuam tshuam rau cable kev ua haujlwm thiab kev pabcuam lub neej. Tsis tas li ntawd, qhov tshwj xeeb cable specifications thiab cov qauv yuav tsum raug xaiv raws li qhov kev thov ib puag ncig. Piv txwv li, nyob rau hauv siab - nce vaj tse, cables nrog zoo saj zawg zog thiab dabtsi yog khoov zog yuav tsum tau xaiv; nyob rau hauv ib puag ncig ntub dej xws li subways, cables uas zoo heev ya raws thiab corrosion kuj yuav tsum tau xaiv.
