Muaj ntau hom kev sib xyaw insulators.

Kev siv cov khoom siv hluav taws xob sib xyaw: yav dhau los, cov khoom siv insulators feem ntau yog siv rau cov khoom siv hluav taws xob. Nrog rau kev txhim kho thev naus laus zis, lawv tau maj mam hloov zuj zus los siv rau ntawm ib kawg ntawm siab -voltage fais fab kab yees, qhov twg ntau disc- zoo li cov insulators tau dai. Cov no yog siv los ua kom qhov kev ncua deb thiab feem ntau yog ua los ntawm iav los yog ceramic; lawv hu ua insulators.

Insulators ua si ob lub luag haujlwm tseem ceeb hauv cov kab xa hluav taws xob: txhawb nqa cov neeg siv khoom thiab tiv thaiv tam sim no rov qab los rau hauv av. Ob txoj haujlwm no yuav tsum tau lav. Insulators yuav tsum tsis txhob poob vim muaj ntau yam kev ntxhov siab electromechanical los ntawm kev hloov ntawm ib puag ncig thiab hluav taws xob load; txwv tsis pub, cov insulators yuav tsis ua lawv txoj haujlwm tseem ceeb, thiab kev pabcuam lub neej ntawm tag nrho cov kab yuav raug cuam tshuam.
