Cov hlau nplaum hlau ntawm cov hlau txuas dej chaw tsim tshuaj paus feem ntau suav nrog txhav hlau thiab cov hlau ntswj hlau. Cov kab hlau ua tiav yog ua los ntawm cov xim liab tooj liab xaim coated nrog insulating varnish. Cov txheej insulating yog nyias thiab hauv pem teb yog me me. Nws yog dav siv nyob rau hauv ntau yam khoom siv hluav taws xob thiab twj paj nruag. Kev ua tau zoo ntawm cov hlau enameled sib txawv nrog qhov ntawm cov khoom siv insulating siv. Cov xaim npog feem ntau suav nrog cov xov xov npog xov, xov paj npog hlau, iav ntsiab lus npog xov hlau, daim ntawv npog xov hlau thiab yas zaj duab xis xaim hlau. Ntawm lawv, vim kev ua haujlwm tsis zoo thaum tshav kub kub thiab cov ntim loj hauv lub xov paj, xov paj ntawm lub xov xov thiab lub xov xov hluav taws xob xaim tuaj yeem raug zam.
Kev rwb thaiv tsev zoo thiab kev siv tshuab ua kom muaj zog. Daim ntawv npog cov hlau tsis zoo yog siv rau cov roj-immersed transformers. Cov hlau xaim nrog cov zaj duab xis yas yog ua los ntawm polyimide zaj duab xis, uas yog coated nrog qee tus nplaum thiab qhwv ntawm tus neeg xyuas pib los ntawm ci. Cov txheej insulating yog tawv, hloov tau yooj yim, cua yooj yim, hnav-thiab cov cua kub-resistant, thiab yog dav siv hauv aerospace thiab lwm yam khoom siv.
Cov kab hluav taws xob uas tsis muaj hluav taws xob txuas ntawm cov tuam txhab ua hluav taws xob tiv thaiv kab ke ua ke muaj cov tub ntxhais kev sib txuas zoo, txheej insulating thiab txheej tiv thaiv. Raws li kev siv cov kev xav tau, tus tub ntxhais tuaj yeem muab faib ua plaub qhov kev teeb tsa: tawv, muag muag, txawb thiab mos mos ntxiv. Muaj plaub lub pob: ib tus ntxhais, ob lub cores, peb cores thiab plaub tus nqi. Cov txheej kab insulating feem ntau yog ua los ntawm roj hmab, yas, thiab lwm yam. Cov kab hlau insulated no yog siv dav hauv ntau yam khoom siv thiab cov ntsuas, cov khoom siv sib txuas lus, cov xov hluav taws xob thiab cov kab teeb pom kev zoo nrog AC voltage tsawg dua 500 volts thiab DC voltage ntawm tsawg dua tshaj li 1000 volts.
Hlau yog qhov khoom siv tsis tseem ceeb hauv cov txheej txheem ntawm cov neeg siv' kev siv hluav taws xob, thiab nws cov txiaj ntsig zoo ncaj qha cuam tshuam rau kev nyab xeeb hluav taws xob ntawm ntau txhiab tsev neeg. Yog li, thaum yuav lossis xaiv, yuav ua li cas xyuas kom sai thiab raug kuaj cov xov hlau (nyiaj xaim, nyiaj them nyiaj xaim, daim hlau tiv thaiv tiv thaiv xaim, tiv thaiv cov hlau them, kub them rau cov xaim, kub them rau cov hlau, kub tiv thaiv hlau, khoos phis tawj hlau, K-hom nyiaj xaim, S-hom nyiaj them nqi Kev ua haujlwm zoo ntawm cov xov hlau thiab lwm cov xov hlau thiab cov xaim hluav taws xob yog kev txawj uas ntau tus neeg siv hluav taws xob yuav tsum txawj.
