Cov kab hluav taws xob ntawm cov ntxhia hauv cov kab hluav taws xob yog tsim los ntawm cov khoom zoo heevconductive tooj, thaum lub rwb thaiv tsev txheej siv inorganic ntxhia cov ntaub ntawv resistant rau kub kub thiab tsis-combustible. Cov txheej txheem sib cais siv cov khoom siv hauv cov ntxhia hauv cov ntxhia, thiab cov ntaub qhwv sab nrauv yog ua los ntawmCov pa luam yeeb tsawg, cov khoom siv yas tsis muaj tshuaj lom, exhibiting zoo heev corrosion kuj. Tau txais kev nkag siab yooj yim ntawm cov pob zeb hauv av, koj puas xav paub lawv cov yam ntxwv tseem ceeb? Wb delve rau hauv qhov ntawd.
01. Hluav Taws Kub Kub:
Mineral cables, ua tiav tag nrho ntawm cov khoom tsis muaj zog, tsis txhob ignite lossis pab combustion. Lawv tsis tsim cov pa phem txawm tias raug nplaim taws sab nraud, ua kom muaj kev ua haujlwm txuas ntxiv tom qab tua hluav taws tsis tas yuav hloov pauv. Cov kab hluav taws xob no yog cov hluav taws kub-resistant tiag tiag, muab kev lees paub rau hluav taws kev nyab xeeb circuits, dhau lub International Electrotechnical Commission's IEC331 xeem.
02. Muaj peev xwm nqa tau tam sim no:
Mineral insulated cables tuaj yeem tiv taus kub txog 250 ℃ thaum lub sijhawm ua haujlwm ib txwm. Raws li IEC60702, qhov ntsuas kub tsis tu ncua rau cov ntxhia insulated cables yog 105 ℃, xav txog cov khoom siv sib khi ntawm lub davhlau ya nyob twg thiab kev nyab xeeb. Txawm li cas los xij, lawv lub peev xwm nqa tam sim no tshaj li ntawm lwm cov cables vim yog magnesium oxide hmoov cov conductivity zoo dua piv rau cov yas. Yog li ntawd, nyob rau tib lub sijhawm ua haujlwm kub, lub peev xwm nqa tam sim no loj dua. Rau cov kab saum toj no 16 hli, ib ntu tuaj yeem raug txo qis, thiab rau thaj chaw tsis tso cai rau tib neeg kev sib cuag, ob ntu tuaj yeem raug txo qis.
03. Waterproof, Explosion-Proof, thiab Corrosion Resistance:
Siv cov pa luam yeeb tsawg, tsis muaj halogen, cov khoom siv hluav taws kub-retardant rau lub sheathing kom muaj kev tiv thaiv corrosion (yas sheathing tsuas yog yuav tsum tau nyob rau hauv cov xwm txheej tshwj xeeb tshuaj corrosion). Tus thawj coj, rwb thaiv tsev, thiab sheathing daim ntawv ntom thiab cog lus, noo noo, roj, thiab tej yam tshuaj txhuas. Cov cables no tsim nyog siv rau hauv qhov chaw tawg, ntau yam khoom tawg-pov thawj, thiab cov khoom siv txuas.
04. Kev tiv thaiv overload:
Nyob rau hauv cov yas cables, overcurrent los yog overvoltage yuav ua rau rwb thaiv tsev cua sov los yog puas thaum lub sij hawm overloads. Txawm li cas los xij, nyob rau hauv cov ntxhia insulated cables, tsuav yog cov cua sov tsis ncav cuag lub melting point ntawm tooj liab, lub cable tseem undamaged. Txawm tias nyob rau hauv instantaneous tawg, qhov kub ntawm magnesium oxide nyob rau hauv lub breakdown point tsis tsim carbides. Tom qab overload clearance, cable qhov kev ua tau zoo tseem tsis hloov thiab tuaj yeem ua haujlwm li qub.
05. Kev ua haujlwm siab:
Lub melting point ntawm magnesium oxide rwb thaiv tsev yog ntau dua li ntawm tooj liab, tso cai rau lub cable lub siab tshaj plaws kev khiav hauj lwm kub mus txog 250 ℃. Nws tuaj yeem ua haujlwm ntawm qhov kub thiab txias ze rau qhov melting point ntawm tooj liab (1083 ℃) rau lub sijhawm luv luv.
06. Muaj zog tiv thaiv kev ua tau zoo:
Copper sheathntawm cable ua hauj lwm raws li ib tug zoo heev shielding tiv thaiv txheej, tiv thaiv ob lub cable nws tus kheej los ntawm kev cuam tshuam nrog lwm yam cables thiab sab nraud magnetic teb los ntawm kev cuam tshuam cov cable.
Ntxiv nrog rau cov yam ntxwv tseem ceeb tau hais los saum no, cov kab hluav taws xob ntxhia kuj muaj cov yam ntxwv zoo li lub neej ntev, me me txoj kab uas hla, lub teeb yuag, siab hluav taws xob tiv thaiv, kev nyab xeeb, kev phooj ywg ib puag ncig, kev puas tsuaj tsis zoo, kev ua haujlwm zoo, thiab kev siv hauv av.
