Kev Nyab Xeeb Hluav Taws Xob thiab qhov tseem ceeb ntawm Circuit Court kev ncaj ncees
Hauv cov tsev niaj hnub thiab cov chaw tsim khoom, cov tshuab hluav taws xob tau sib xyaw ua ke rau hauv cov tswv yim kev nyab xeeb hluav taws. Thaum muaj hluav taws kub, tswj kev ua haujlwm ntawm cov hluav taws xob tseem ceeb- xws li hluav taws kub tswb, teeb pom kev kub ceev, tshem tawm cov pa taws, thiab cov khoom siv tua hluav taws- yog qhov tseem ceeb rau kev tiv thaiv lub neej thiab khoom.
Hluav taws kub- cov kab hluav taws xob tiv taus yog tsim los rau lub hom phiaj no. Ntawm tag nrho cov khoom siv hauv lawv cov kev tsim kho,mica daim kab xev plays lub luag hauj lwm txiav txim siab thiab irreplaceable. Yog tsis muaj mica daim kab xev, feem ntau cov hluav taws kub- cov kab hluav taws xob tiv taus yuav tsis tuaj yeem tswj xyuas kev ncaj ncees ntawm cov hluav taws xob ncaj qha.
Kab lus no muab cov lus piav qhia dav dav ntawm:
Mica daim kab xev yog dab tsi
Nws ua haujlwm li cas hauv qhov hluav taws kub
Qhov twg nws nyob hauv qhov hluav taws kub -cov kab hluav taws xob tiv taus
Yog vim li cas nws yog ib qho tseem ceeb rau fireproofing kev ua tau zoo
Mica daim kab xev yog dab tsi?
Basic txhais
Mica daim kab xev yog ibnyias, yoog raws cov khoom siv insulatingua los ntawm kev sib txuas ntuj los yog hluavtaws mica flakes nrog lub tshav kub-cov ntaub ntawv tiv thaiv thiab txhawb lawv nrog fiberglass lossis polymer films.
Mica nws tus kheej yog ib txwm tshwm sim ntxhia paub rau:
Tsis tshua muaj kub tsis kam
Zoo heev dielectric (hluav taws xob rwb thaiv tsev) zog
Tshuaj thiab thermal stability
Cov khoom no ua rau mica tshwj xeeb tsim rau hluav taws kub- cov ntawv thov hluav taws xob tiv taus.
Hom Mica siv hauv Cables
Ob yam khoom siv mica uas siv hauv hluav taws kub -cov kab hluav taws xob tiv taus yog:
Phlogopite mica- nyiam rau siab - qhov kub thiab txias (txog ~ 1000 degree)
Muscovite mica- siv nyob rau hauv nruab nrab siab -tej daim ntawv thov kub
Rau hluav taws- cov kab hluav taws xob tiv taus,phlogopite mica daim kab xevyog tus qauv kev lag luam vim nws superior thermal stability.
Fireproofing vs Flame Retardancy: Vim li cas Mica Daim Kab Xev Teeb Meem
Txhawm rau nkag siab lub luag haujlwm ntawm mica daim kab xev, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm ob lub ntsiab lus:
Nplaim-kev ua haujlwm tsis zoo: txwv cov nplaim taws sib kis thiab tus kheej - tua tom qab hluav taws kub
Hluav taws kub-resistant (fireproof) kev ua tau zoo: tuav hluav taws xob ua haujlwm thaum hluav taws kub
Cov nplaim taws zoo tib yam- cov khoom siv retardant:
Maj mam hlawv
Nws thiaj li degrade nyob rau hauv sustained hluav taws
Mica daim kab xev, los ntawm qhov sib txawv:
Ua litsis hlawv
Ua litsis yaj
Ua litsis poob rwb thaiv tsevntawm qhov kub thiab txias
Qhov no ua rau mica daim kab xevcore fireproofing keebhauv hluav taws- cov kab hluav taws xob.
Qauv ntawm aHluav taws kub-Resistant Cable
Txhawm rau kom nkag siab tias mica daim kab xev ua haujlwm li cas, nws yog ib qho tsim nyog yuav tsum tau tshuaj xyuas covcov qauv ntawm hluav taws kub-resistant cable.
Hom Txheej Txheej Txheem
Los ntawm sab hauv sab nraud, hluav taws kub -cov kab hluav taws xob feem ntau muaj xws li:
tooj liab conductor
Mica daim kab xev hluav taws kub- txheej tiv taus
Kev rwb thaiv tsev tseem ceeb(piv txwv li, silicone roj hmab lossis hluav taws kub - ntsuas XLPE)
