Muaj ob lub ntsiab ntawm cov hlau nplaum hlau: enameled hlau thiab qhwv hlau. Enameled hlau yog tsim los ntawm txheej insulating kua roj vanish ntawm liab qab tooj liab hlau. Cov txheej insulating yog nyias thiab ntim me me. Nws yog dav siv nyob rau hauv ntau yam khoom siv hluav taws xob thiab cov cuab yeej siv. Kev ua haujlwm ntawm enameled hlau txawv nrog qhov xwm txheej ntawm cov khoom siv insulating siv.
Cov xov hlau qhwv feem ntau suav nrog cov xov paj uas muaj cov xov paj, cov ntaub qhwv cov xov paj, cov iav fiber ntau npog hlau, daim ntawv npog hlau thiab cov yas zaj duab xis npog hlau. Ntawm lawv, cov xov paj npog cov xov hlau thiab cov xov paj xov paj yuav raug tshem tawm vim qhov kub tsis zoo thiab cov khoom ntim loj. Cov iav fiber ntau npog hlau yog ib puag ncig tooj liab hlau qhwv nrog iav fiber ntau thiab impregnated nrog silicone resin. Nws tuaj yeem tiv taus qhov kub siab ntawm 180 ° C thiab muaj cov khoom siv rwb thaiv tsev zoo thiab lub zog txhua yam. Daim ntawv npog hlau yog tsuas yog siv rau roj-immersed transformers.
Cov yas zaj duab xis npog hlau yog ua los ntawm polyimide zaj duab xis coated nrog ib qho nplaum thiab qhwv ntawm tus neeg xyuas pib los ntawm ci. Nws cov txheej insulating yog tawv thiab elastic, yooj yim rau cua, hnav-resistant thiab kub-resistant, thiab yog dav siv nyob rau hauv astronautics thiab lwm yam khoom siv. Insulated xov hlau feem ntau muaj cov tub ntxhais conductive, ib txheej insulating thiab txheej tiv thaiv. Cov tub ntxhais tuaj yeem muab faib ua plaub qhov kev teeb tsa: tawv, mos, txawb thiab muag muag ntxiv raws li qhov xav tau ntawm kev siv. Muaj plaub cores: ib tug tub ntxhais, ob tug tub ntxhais, peb cores thiab plaub cores. Cov txheej txheej insulating feem ntau yog ua los ntawm cov roj hmab, yas, thiab lwm yam. Hom kab hluav taws xob no yog siv dav hauv ntau yam cuab yeej thiab cov ntsuas, cov khoom siv sib txuas lus, cov kab hluav taws xob thiab cov teeb pom kev zoo nrog AC voltage qis dua 500 volts thiab DC voltage hauv qab 1000 volts.
