Cov hlau yog cov xaim xaim hluav taws xob. Nws muab faib ua liab qab hlau, hlau nplaum hlau thiab insulated hlau. Cov xov hlau liab qab tsis muaj txheej txheej rwb thaiv tsev, suav nrog tooj liab, aluminium tiaj tus xaim, nyiaj siv ua haujlwm stranded xov hlau, thiab ntau yam profiles (xws li molded xov hlau, tsheb npav, tooj liab, txhuas tuav, thiab lwm yam). Nws yog tsuas yog siv rau sab nraum zoov nyiaj siv ua haujlwm thiab sab hauv tsev busbars thiab hloov lub thawv.
Cov hlau nplaum hlau yog cov hlau nplaum uas tsim cov hlau nplaum sib nqus los yog induces tam sim no hauv magnetic teb tom qab energized. Nws yog tsuas yog siv rau winding motors thiab transformers thiab lwm yam khoom siv electromagnetic. Tus neeg xyuas pib feem ntau yog tooj liab xaim, uas yuav tsum muaj txheej txheej nyias nyias thiab cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob, nrog rau kev ua haujlwm kub, dej tsis kam, thiab hnyav ua haujlwm. Xaiv cov ntaub ntawv insulating sib txawv kom tau txais cov yam ntxwv sib txawv.
