1. Insulators feem ntau muab faib ua hom kev tawg thiab tsis tawg.
2. Raws li cov qauv, nws tuaj yeem muab faib ua cov ncej (ncej) insulator, ncua kev kawm insulator, tus pin insulator, npauj npaim insulator, nro insulator, tiv thaiv muaj kuab paug nyob hauv dej flushing insulator thiab bushing insulator.
3. Raws li lub sijhawm thov, nws tau muab faib ua kab insulator, fais fab chaw nres tsheb insulator thiab hluav taws xob insulator. Ntawm lawv, cov kev puas tsuaj hom insulators siv nyob rau hauv txoj kab muaj xws li hom pin, hom npauj npaim thiab disc-zoo li lub ncua kev kawm ntawv hom, thiab cov tsis tawg hom muaj xws li hla caj npab thiab pas nrig-zoo li lub ncua kev kawm ntawv hom. Kev tawg hom rau cov chaw nres tsheb fais fab thiab cov khoom siv hluav taws xob
Cov insulators muaj xws li tus pin ncej, hollow ncej thiab bushing, thiab cov tsis tawg hom muaj xws li pas nrig ncej thiab thawv porcelain bushing.
4. Insulators siv nyob rau hauv overhead kab muaj xws li tus pin insulators, npauj npaim insulators, suspension insulators, porcelain cross caj npab, qws insulators thiab nro insulators.
5. Cov insulators muaj xws li: ceramic insulator, FRP insulator, composite insulator thiab semiconductor insulator.
