Cov Hlau Uas Muaj Cov Khoom Siv Hluav Taws Xob (MI Cable) yog cov hlau uas tiv taus hluav taws kub zoo uas siv cov khoom siv hluav taws xob uas tsis muaj cov khoom siv hluav taws xob. Tsis zoo li cov hlau ib txwm uas siv cov khoom siv rwb thaiv tsev polymer xws li PVC,XLPE, thiabLSZH, MI cable yog tsim los ntawm kev siv tus neeg hlau tooj liab, lub plhaub tooj liab tsis muaj qhov sib txuas, thiab cov khoom siv rwb thaiv tsev inorganic magnesium oxide (MgO) ua nws cov qauv tseem ceeb. Cov khoom siv no txiav txim siab nws qhov kev ua haujlwm ruaj khov hauv qab qhov kub thiab txias thiab hluav taws kub.
Los ntawm qhov kev xav ntawm kev tsim cov ntaub ntawv cable, cov txheej txheem khoom siv inorganic tshem tawm cov teeb meem ntawm kev lwj, yaj, thiab tso pa lom uas tshwm sim hauv cov ntaub ntawv organic hauv qab qhov kub siab. Qhov no ua rau MI cable yog qhov kev daws teeb meem tseem ceeb rau cov cables tiv taus hluav taws, cov cables kub siab, thiab cov ntaub ntawv cable tseem ceeb ntawm lub zog hluav taws xob.
Cov Qauv Khoom Siv thiab Cov Khoom Siv
Qhov ua tau zoo ntawm MI cable feem ntau yog txiav txim siab los ntawm nws cov khoom siv cable tseem ceeb. Tus conductor yog ua los ntawm cov tooj liab ntshiab, uas muab kev ua hluav taws xob zoo heev thiab tsis tshua muaj kev tiv thaiv, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob cable.
Cov txheej rwb thaiv tsev siv magnesium oxide (MgO rwb thaiv tsev), uas yog cov khoom siv rwb thaiv tsev inorganic cable uas muaj qhov kub yaj tshaj 2800°C. Nws tswj tau qhov ua haujlwm dielectric ruaj khov txawm tias nyob hauv qhov kub thiab txias heev, ua lub hauv paus tseem ceeb uas ua rau tiv taus hluav taws.
Cov txheej sab nraud muaj lub plhaub tooj liab uas tsis muaj qhov sib txuas, uas muab kev tiv thaiv txhua yam thiab tiv taus xeb. Nws kuj muaj kev ua tau zoo heev ntawm kev ua kom sov thiab kev tiv thaiv hluav taws xob (EMI shielding). Tsis tas li ntawd, lub plhaub tooj liab tuaj yeem ua haujlwm ua tus neeg hlau av, ua kom yooj yim rau kev tsim qauv thiab txhim kho kev ntseeg siab ntawm kev ua haujlwm.
Kev Ua Haujlwm Hluav Taws thiab Cov Khoom Siv Zoo
Nyob rau hauv cov xwm txheej hluav taws, qhov sib txawv ntawm cov khoom siv ua rau muaj qhov tseem ceeb. Cov ntaub ntawv polymeric cable ib txwm muaj feem pib lwj lossis ua tsis tiav ntawm qhov kub ntawm 300 ° C thiab 500 ° C, tso pa luam yeeb thiab cov pa phem.
Qhov sib txawv, MI cable yog ua los ntawm cov khoom siv rwb thaiv tsev inorganic, thiab tuaj yeem tswj tau qhov hluav taws xob zoo hauv qab nplaim taws ncaj qha ntawm kwv yees li 950 ° C. Nws muaj peev xwm ua haujlwm tas mus li rau ntau tshaj 90 feeb, ua tau raws li cov qauv tiv thaiv hluav taws thoob ntiaj teb xws li BS 6387 thiab IEC 60331.
Lub caij no, nws cov ntaub ntawv cable uas tsis kub hnyiab tsis kub hnyiab, tsis tsim pa luam yeeb, thiab tsis tso cov pa phem tawm, ua rau MI cable yog ib qho kev daws teeb meem rau cov ntaub ntawv cable ciaj sia nyob hluav taws uas siv dav hauv kev muab hluav taws xob thaum muaj xwm txheej ceev thiab cov kab ke tiv thaiv hluav taws.
Cov txiaj ntsig thiab cov teeb meem uas siv cov khoom siv
Los ntawm qhov pom ntawm cov khoom siv cable, MI cable muaj kev tiv thaiv hluav taws, muaj peev xwm nqa hluav taws xob tau zoo, thiab lub neej ua haujlwm ntev (feem ntau 40-60 xyoo). Nws tsim nyog rau qhov kub thiab txias, av noo, thiab qhov chaw muaj kev phom sij.
Txawm li cas los xij, vim yog siv cov khoom siv tooj liab thiab magnesium oxide rwb thaiv tsev (MgO rwb thaiv tsev) ntau heev, tus nqi tag nrho ntawm cov khoom siv yog siab dua li cov kab ke cable ib txwm muaj. Tsis tas li ntawd, cov qauv inorganic tag nrho ua rau muaj kev ruaj khov dua, uas ua rau muaj kev cai nruj dua rau kev teeb tsa cable, kev ua haujlwm khoov, thiab cov txheej txheem kaw.
Cov qauv tsim MI cable uas yooj ywm tuaj yeem txhim kho kev ua haujlwm ntawm kev teeb tsa, tab sis lawv kuj ua rau cov khoom siv thiab kev tsim khoom nyuaj dua.
Cov Ntawv Thov Ib Txwm Muaj
Vim nws cov khoom siv hluav taws kub zoo heev, MI cable siv dav hauv cov tsev siab tiv thaiv hluav taws, kev thauj mus los ntawm tsheb ciav hlau, cov chaw pej xeem loj, thiab cov chaw ua lag luam roj av uas muaj qhov kub thiab txias thiab muaj kev pheej hmoo hluav taws.
Hauv cov ntawv thov no, kev ua haujlwm ruaj khov ntawm nws cov khoom siv cable system ua kom muaj kev muab hluav taws xob tas mus li hauv qab hluav taws lossis cov xwm txheej hnyav, ua rau nws yog qhov kev daws teeb meem tseem ceeb rau cov kab ke fais fab tseem ceeb.
Xaus Lus: Cov Qauv Hauv Kev Txhim Kho Cov Khoom Siv Cable
Los ntawm qhov kev xav ntawm cov qauv kev txhim kho ntawm cov ntaub ntawv cable, MI cable sawv cev rau kev hloov pauv loj ntawm cov ntaub ntawv rwb thaiv tsev organic mus rau cov ntaub ntawv rwb thaiv tsev inorganic.
Rau cov neeg muab khoom siv cable, lub peev xwm hauv kev tswj hwm qhov huv, qhov loj me ntawm cov khoom me me, kev tiv thaiv dej noo, thiab cov khoom ntws ntawm magnesium oxide (MgO rwb thaiv tsev), nrog rau kev muab khoom ruaj khov ntawm cov neeg hlau tooj liab thiab cov ntaub ntawv tooj liab, yuav yog cov yam tseem ceeb hauv kev sib tw hauv kev lag luam cov khoom siv cable tiv taus hluav taws kub siab.
Peb txuas ntxiv tsom mus rau thiab muab cov kev daws teeb meem cable, txhawb cov neeg siv khoom hauv kev siv MI cable thiab lwm yam kev ua haujlwm siab-resistant hluav taws cable systems.
