Raws li cov qauv kev nyab xeeb hluav taws txuas ntxiv nce siab thoob plaws hauv kev lag luam xws li kev tsim kho vaj tse, kev thauj mus los ntawm tsheb ciav hlau, cov chaw khaws ntaub ntawv, cov roj av, thiab lub zog rov ua dua tshiab, Cov Hlau Uas Muaj Cov Khoom Siv Hluav Taws Xob (MI) tau dhau los ua qhov kev daws teeb meem zoo rau cov hluav taws xob tseem ceeb ua tsaug rau lawv qhov kev tiv thaiv hluav taws zoo heev thiab kev ntseeg siab mus sij hawm ntev.
Piv nrog cov xov hluav taws xob ib txwm muaj, cov xov hluav taws xob MI tuaj yeem tswj tau qhov kev sib txuas lus zoo thaum muaj hluav taws, ua kom muaj kev xa hluav taws xob tas mus li rau cov kab ke tseem ceeb xws li cov twj tua hluav taws, teeb pom kev thaum muaj xwm txheej ceev, lub tshuab nqa neeg, thiab lwm yam khoom siv kev nyab xeeb rau lub neej.
Rau cov chaw tsim khoom siv cable, kev ua tau zoo ntawm cable tsis yog nyob ntawm kev tsim cable xwb tab sis kuj nyob ntawm qhov zoo ntawm cov ntaub ntawv siv cable. Magnesium oxide (MgO), cov neeg hlau tooj liab, cov ntaub thaiv tooj liab tsis sib xws,daim kab xev mica, daim kab xev iav fiber, thiabCov tshuaj LSZHtxhua tus ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ua tau ntawm cov cable, kev tiv thaiv hluav taws, thiab kev ntseeg tau mus sij hawm ntev.
Cable uas muaj cov mineral insulated (MI) yog dab tsi?
Ib txoj hlua MI ib txwm muaj ib lub tooj liab conductor, high-purity magnesium oxide (MgO) rwb thaiv tsev, thiab ib lub plhaub tooj liab seamless rau kev tiv thaiv tshuab.
Vim tias nws cov rwb thaiv tsev yog ua los ntawm cov khoom inorganic es tsis yog cov polymers uas kub hnyiab tau, MI cable yuav luag tsis muaj pa luam yeeb lossis cov pa roj corrosive thaum muaj hluav taws thaum tseem tswj tau cov hluav taws xob rwb thaiv tsev zoo heev. Qhov no ua rau nws yog ib qho kev daws teeb meem siv dav rau cov kab ke cable uas tiv taus hluav taws.
Nyob rau xyoo tas los no, cov xov hlau uas muaj cov khoom siv hluav taws xob uas yooj ywm tau nrov zuj zus. Cov qauv no feem ntau muaj cov kab xev mica, cov kab xev iav fiber, thiab cov tshuaj sib xyaw Low Smoke Zero Halogen (LSZH) los muab kev ua haujlwm hluav taws zoo heev thaum txhim kho kev yooj ywm ntawm kev teeb tsa.
Cov txiaj ntsig ntawm MI Cables
Qhov zoo tshaj plaws ntawm MI cables yog lawv txoj kev tiv taus hluav taws kub zoo heev. Txawm tias nyob rau hauv cov xwm txheej hluav taws kub, lawv tuaj yeem tswj tau qhov kev ua haujlwm ntawm lub voj voog thiab txuas ntxiv muab hluav taws xob rau cov kab ke kev nyab xeeb tseem ceeb.
Lub plhaub tooj liab tsis muaj qhov tsis sib xws kuj muab lub zog kho tshuab siab, tiv taus kev hnav zoo heev, thiab tiv taus cov dej noo, roj, thiab ntau yam tshuaj lom neeg, ua rau MI cables tsim nyog rau cov chaw ib puag ncig uas xav tau kev kub ntxhov xws li kev thauj mus los ntawm tsheb ciav hlau, cov chaw tsim hluav taws xob, cov chaw tsim tshuaj petrochemical, thiab kev teeb tsa kev lag luam.
Piv rau cov xov hluav taws xob ib txwm muaj, cov xov hluav taws xob MI feem ntau muaj peev xwm nqa hluav taws xob ntau dua, lub neej ua haujlwm ntev dua, thiab qhov yuav tsum tau saib xyuas qis dua, ua rau lawv haum rau cov ntawv thov tseem ceeb uas xav tau kev ua haujlwm tas mus li.
Cov Kev Txwv ntawm MI Cables
Txawm hais tias lawv cov txiaj ntsig, MI cables kuj muaj ntau qhov kev txwv.
Vim tias lawv siv tooj liab ntau heev rau ob qho tib si tus neeg coj thiab lub hnab, cov nqi khoom siv feem ntau siab dua li cov xov hluav taws xob ib txwm muaj, ua rau tus nqi teeb tsa siab dua.
Cov xov hlau MI ib txwm muaj kev ywj pheej tsawg, ua rau kev teeb tsa thiab kev xaus nyuaj dua thiab xav tau kev txawj ntse ntau dua.
Ntxiv mus, magnesium oxide (MgO) yog hygroscopic. Yog tias cov xov hlau tsis tau kaw kom zoo, cov dej noo tuaj yeem nkag mus rau hauv cov rwb thaiv tsev, txo qhov tsis kam ntawm rwb thaiv tsev. Vim li no, kev kaw kom zoo ntawm cov xov hlau kawg yog qhov tseem ceeb rau kev ntseeg tau mus sij hawm ntev.
Cov Khoom Siv Cable Cuam Tshuam Li Cas Rau Kev Ua Haujlwm ntawm MI Cable?
Qhov kev ua tau zoo ntawm MI cable tsis yog nyob ntawm nws cov qauv tsim xwb tab sis kuj nyob ntawm qhov zoo thiab kev sib xws ntawm nws cov ntaub ntawv cable.
Cov magnesium oxide uas muaj purity siab (MgO) muab kev rwb thaiv hluav taws xob txhim khu kev qha, thaum cov hlau tooj liab uas muaj conductivity siab thiab cov hlau tooj liab seamless pab txhawb rau kev ua haujlwm hluav taws xob zoo heev thiab lub zog kho tshuab.
Rau cov cables uas muaj cov khoom siv hluav taws xob uas yooj ywm thiab lwm yam qauv cables uas tiv taus hluav taws, cov ntaub ntawv xws li daim kab xev mica, daim kab xev iav fiber, daim kab xev tooj liab, thiab cov tshuaj LSZH kuj tseem ua lub luag haujlwm tseem ceeb. Cov ntaub ntawv no pab txhim kho kev ua haujlwm hluav taws, kev tiv thaiv tshuab, kev ruaj khov ntawm kev ua haujlwm, kev ua haujlwm zoo, thiab kev sib xws ntawm cov khoom.
Rau cov chaw tsim khoom siv cable, kev xaiv cov khoom siv cable zoo nrog kev ua haujlwm ruaj khov thiab kev ua haujlwm zoo tuaj yeem txhim kho kev tsim khoom thaum txhim kho kev ntseeg siab mus sij hawm ntev thiab kev pabcuam lub neej ntawm cov cable tiav lawm.
Xaus lus
Ua tsaug rau lawv txoj kev tiv thaiv hluav taws zoo heev, lub zog kho tshuab, thiab kev ntseeg tau ntev, MI cables tau siv dav hauv cov kab ke tiv thaiv hluav taws, kev thauj mus los ntawm tsheb ciav hlau, cov chaw khaws ntaub ntawv, cov khoom siv hluav taws xob, thiab lwm yam kev siv tseem ceeb.
Tib lub sijhawm, cov ntaub ntawv tseem ceeb ntawm cov xov hlau—xws li magnesium oxide (MgO), cov hlau tooj liab, cov hlau tooj liab tsis muaj qhov sib txuas, daim kab xev mica, daim kab xev iav fiber, thiab cov tshuaj LSZH—muaj feem cuam tshuam ncaj qha rau qhov zoo ntawm kev tsim khoom, kev ua haujlwm hluav taws, thiab kev ntseeg siab ntawm cov xov hlau mus sij hawm ntev.
Raws li qhov kev thov rau cov kab hluav taws xob uas tiv taus hluav taws txuas ntxiv mus, cov chaw tsim khoom siv hluav taws xob tab tom muab qhov tseem ceeb dua rau kev ua haujlwm ntawm cov khoom siv thiab kev ua haujlwm sib xws. Kev xaiv cov ntaub ntawv cable zoo thiab kev ua kom zoo dua qub ntawm kev tsim qauv cable thiab cov txheej txheem tsim khoom tuaj yeem pab txhim kho qhov sib xws ntawm cov khoom thiab ua tau raws li qhov kev thov nce ntxiv rau cov kev daws teeb meem cable uas ntseeg tau siab.
