Hauv hav zoov steel ntawm cov tsev niaj hnub thiab cov chaw tsim khoom lag luam, suav tsis txheeb cables muaj kev sib tshuam zoo li lub paj hlwb ntawm tib neeg lub cev. Thaum hluav taws kub hauv chav tsev siab siab hauv Dubai xyoo 2022 ua rau muaj kev sib kis ntawm cov kab hluav taws xob zoo tib yam, cov kws ua haujlwm thoob plaws ntiaj teb tau tsom mus rau cov nplaim hluav taws xob thev naus laus zis ntawm cables. Qhov kev huam yuaj uas ua rau ntau lab nyiaj daus las tau nthuav tawm qhov kev muaj tiag tiag: nyob rau hauv lub ntsej muag ntawm cov hluav taws kub, cov kab hluav taws xob zoo tib yam feem ntau dhau los ua cov neeg tuag taus. Hluav taws kub retardant cables yog cov thev naus laus zis tseem ceeb hauv kev nyab xeeb hluav taws xob, thiab lawv qhov tseem ceeb yog tsis muaj tsawg tshaj li qhov hluav taws kub tsim ntawm lub tsev. Qhov tshwj xeeb cable no tuaj yeem tuav cov qauv ua tiav hauv cov nplaim taws, tiv thaiv kev sib kis ntawm hluav taws, thiab siv zog rau lub sijhawm muaj txiaj ntsig rau cov neeg ua haujlwm khiav tawm thiab tua hluav taws. Nws yog ib qho tseem ceeb "lifeline" nyob rau hauv niaj hnub kev ruaj ntseg kev tiv thaiv system. Nyob rau hauv lub tshav pob ntawm super high-sawv vaj tse, daim ntawv thov ntawm nplaim retardant cables yog ncaj qha ntsig txog lub peev xwm ntawm kev tiv thaiv kev puas tsuaj thiab tswj. Nyob rau hauv lub hwj chim mov system ntawm Shanghai Central Building, tag nrho cov ntsug cables siv Class B1 nplaim retardant txheem, thiab txhua meter cable muaj ntau tshaj 300g inorganic nplaim retardant muab tub lim. Qhov kev tsim no tso cai rau 20-storey cable ncej kom kis tau qhov ceev ntawm qhov hluav taws kub kis mus rau 1/5 ntawm lub tsev pa hauv qhov simulated tua hluav taws. Cov nplaim hluav taws kub hnyiab tau siv nyob rau hauv lub tsev ntse ntse, nws cov khoom tshwj xeeb sheath yuav ua npuas ncauj thiab nthuav dav thaum kub hnyiab, tsim cov thermal rwb thaiv tsev txheej nrog ib txoj kab uas hla ntawm 3 npaug ntawm qhov loj me, tiv thaiv cov khoom siv kho qhov muag sab hauv los ntawm kev puas tsuaj. Txoj kev tsheb ciav hlau txoj kev tsheb ciav hlau muaj qhov yuav tsum tau nruj dua rau cov nplaim hluav taws xob ua haujlwm ntawm cov cables. Cov nplaim hluav taws kub hnyiab tau siv nyob rau hauv subway tunnel yuav tsum tau ntawv pov thawj HL3 hauv EN 45545-2 tus qauv, uas txhais tau hais tias thaum lub cable raug kub hnyiab hauv qhov kub ntawm 800 ° C, cov pa taws ceev tsis tshaj 0.5m² / s ib feeb. Siemens, Lub teb chaws Yelemees, tau tsim tshwj xeeb tsim hluav taws xob tshwj xeeb cable rau Munich subway. Nws siv ob txheej mica siv qhwv cov qauv. Hauv kev sim combustion, lub teeb xa hluav taws xob ntawm cov pa hluav taws xob ib txwm nyob siab dua 80%, uas ua rau pom kev zoo hauv qhov chaw ib puag ncig.
