Tus nqi qis qis: vim yog kev tsim cov thev naus laus zis thev naus laus zis thiab kev teeb tsa yooj yim, cov nqi sib tw ntawm cov hluav taws xob hluav taws xob hloov pauv tau qis dua li cov ntxhia insulated cable nyob rau hauv tib lub sijhawm.
Muaj pes tsawg leeg ntawm cov ntxhia pob zeb insulated cable (bbtrz): saj zawg zog ntxhia insulated cable yog tsim los ntawm tooj liab stranded hlau, ntxhia compound rwb thaiv tsev thiab ntxhia compound sheath. Nws txais cov qauv hloov tau yooj yim, thiab cov ntaub ntawv tseem ceeb yog cov ntaub ntawv inorganic, uas ua rau cov teeb meem ntawm cov qauv nyuaj, yooj yim combustion thiab toxicity. Nws kuj muaj qee qhov zoo uas lwm cov cables tsis tuaj yeem muaj, xws li hluav taws kub tsis kam, muaj peev xwm nqa tam sim no, impulse voltage tsis kam, txhua yam kev puas tsuaj, halogen tsis muaj tshuaj lom thiab tsis muaj tshuaj lom, tawg-pov thawj, tsis muaj dej, corrosion kuj, kev pab lub neej ntev, kev nyab xeeb, overload tsis kam, kub tsis kam thiab tus nqi qis.
Flexible mineral insulated cable (bbtrz) muaj cov yam ntxwv ntawm cov khoom. Vim hais tias cov rwb thaiv tsev ntawm cov xov hlau thiab cables yog tsim los ntawm cov khoom siv organic polymer, nws yooj yim heev rau carbonize nyob rau hauv cov nplaim taws thiab poob lub rwb thaiv tsev ua haujlwm. Txij li cov ntaub ntawv tseem ceeb ntawm cov khoom siv hluav taws xob hloov pauv hluav taws xob hluav taws xob hluav taws xob (bbtrz) yog tsim los ntawm cov ntxhia sib txuas, nws tus kheej yuav tsis ua rau hluav taws thiab tsis tuaj yeem hlawv lossis txhawb kev sib txuas. Cov ntaub ntawv no feem ntau muaj qhov kub ntawm qhov kub siab tshaj 1500 degree, yog li cov hluav taws kub-pov thawj cable tuaj yeem ua lub zog xa hluav taws xob ib txwm muaj txawm tias nyob rau hauv qhov xwm txheej ntawm nplaim taws, uas yog qhov hluav taws kub-pov thawj cable.
Cov txheej txheem txheej txheem ntawm cov khoom siv hluav taws xob hloov hluav taws xob hluav taws xob hluav taws xob (bbtrz) yog tib yam li cov khoom siv hluav taws xob, uas ua tiav kev daws teeb meem ntau yam tsis zoo ntawm cov khoom txiav txim siab los ntawm cov txheej txheem tsim khoom ntawm magnesium oxide tooj liab pas nrig ntxhia insulated cable (bttz).
Cov ntsiab lus ntawm qhov zoo: nws yog qhov hloov tau tiag tiag, thiab cov qauv yog mos zoo li cov cables zoo tib yam. Cov txheej txheem txheej txheem yog tib yam li cov cables zoo tib yam. Cov theoretical ntau lawm yog infinite, thiab ib tug cable yuav ua tau nyob rau hauv tas mus li ntev. Lub installation tsis muaj kev sib koom ua ke, kev tsim kho yog yooj yim, kev ntseeg tau zoo dua thiab cov nqi nkag tau txo. Ntau cov tub ntxhais tuaj yeem tsim tau 300mm2, kov yeej qhov tsis txaus ntawm ib leeg tub ntxhais nrog nruj bttz ntawm ntau tshaj 25mm2. 5. Lub cable tuaj yeem rov qab siv tau. Nyob rau hauv rooj plaub ntawm kab rov tsim kho thiab hloov kho, lub cable tuaj yeem raug tshem tawm thiab rov siv dua.
Cov yam ntxwv ntawm cov ntxhia yooj yim insulated cable: nws txhim kho kev ruaj ntseg ntawm rwb thaiv tsev: nws tsis tsuas yog khaws cov hluav taws kub tsis zoo ntawm cov ntxhia insulated cable, tab sis kuj muaj cov yam ntxwv uas nws tsis haum rau kev nqus noo noo, yog li cov rwb thaiv tsev ruaj khov dua. Qhov kev tiv thaiv hluav taws xob tau zoo dua: cov qib tiv thaiv hluav taws xob tuaj yeem ncav cuag 1000V, uas txo ntau qhov impulse voltages tshwm sim los ntawm kev pib nquag ntawm inductors thiab zaus hloov dua siab tshiab, thiab raws li zoo heev txhim kho kev pab cuam lub neej ntawm kab system. Tag nrho series: nws tuaj yeem ua tiav rau hauv ib qho tseem ceeb lossis ntau tus qauv raws li qhov xav tau tiag tiag ntawm cov neeg siv, txog li 96 cores, uas tuaj yeem yuav luag them cov kev xav tau ntawm lub tsev cables ntawm ntau yam tshwj xeeb xws li fais fab cables thiab tswj cables.
Tsis muaj kev sib koom ua ke nruab nrab: kev paub tab cov hlua khi hlua khi thiab cov tshuab cabling tau txais kev pom zoo, uas tuaj yeem tsim tau ntev raws li tus neeg siv cov kev xav tau, uas tsis tsuas yog txo cov nqi sib koom, tab sis kuj txhim kho thiab paub txog tag nrho cov kab sib xws. Saj zawg zog thiab yooj yim rau nruab: vim hais tias ntawm cov tsoos cable qauv xws li stranded hlau thiab cable, lub cable yog ntau saj zawg zog. Nyob rau tib lub sijhawm, vim tsis muaj qhov xav tau tshwj xeeb lub davhlau ya nyob twg txuas, nws yooj yim dua rau kev teeb tsa thiab tso. Qhov chaw txuag: txij li ntau cov tub ntxhais cables nrog cov ntu loj thiab ntev tuaj yeem muab tau, qhov tsis tsim nyog tso chaw pov tseg los ntawm ntau qhov kev npaj thiab cov pob qij txha nruab nrab yog zam.
Kev noj qab haus huv rau pej xeem: vim yog kev txhim kho ntawm cov qauv, ntau cov ntxhia thiab cov ntxhia sib xyaw yog siv, uas tsis tsuas yog txuag tooj liab, magnesium thiab lwm yam kev pab, tab sis kuj txuag tau ntau lub zog siv raws li. Tus nqi nyiaj pab pej xeem kuj tseem ceeb heev.
Kev teeb tsa thiab tso cov kab hluav taws xob hloov pauv tau yooj yim: thaum lub cable raug nthuav tawm, nws yuav tsum tau txais kev txhawb nqa los ntawm kev txhawb nqa cable, nuv lossis hlau nqa hlua nrog tag nrho ntev. Qhov siab tshaj plaws yuav tsum tau ua raws li cov kev cai hauv qab no: ua tau raws li qhov muaj peev xwm ntawm cov khoom txhawb nqa thiab cov txheej txheem sab nrauv thiab cov tub ntxhais ntawm cov kab tsis zoo, yog li cov cables tuaj yeem tsim kom zoo nkauj thiab yoog raws li qhov yuav tsum tau ua hauv kev ua haujlwm.
Cov ntxhia yooj yim insulated fireproof cable tuaj yeem siv thaum muaj xwm txheej ceev tom qab kev teeb tsa. Nws kuj tseem siv tau los ua 125 degree kub resistant halogen-dawb nplaim retardant cable thiab hluav taws-resistant cable. Vim tias nws qhov kev pabcuam dav dav, cov xov tooj ntawm cov xov tooj no tsis tsuas yog kov yeej qhov tsis xws luag ntawm Mi cable, muab kev ua si tag nrho rau qhov zoo ntawm kev hloov pauv Mi cable, tab sis kuj muab cov khoom siv rau cov haujlwm tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov ntawm cov tsev siab siab. , yog li ntawd kev nyab xeeb ntawm tib neeg lub neej thiab cov khoom muaj kev ntseeg siab tau lees paub, Tib lub sijhawm, nws kuj txhawb txoj kev loj hlob ntawm nws txoj kev lag luam.
