1. Insulated nkawm khau yuav tsum raug xaiv raws li qhov siab thiab qis voltage ntawm qhov chaw ua haujlwm. Tsawg-voltage insulated khau yog txwv tsis pub siv los ua kev pabcuam kev nyab xeeb ntawm cov khoom siv hluav taws xob high-voltage. High-voltage insulated khau (khau raj) tuaj yeem siv los ua cov cuab yeej pabcuam kev nyab xeeb ntawm cov khoom siv hluav taws xob siab thiab cov khoom siv hluav taws xob tsawg. Txawm li cas los xij, txawm hais tias nws hnav tsis muaj hluav taws xob lossis hluav taws xob muaj hluav taws xob (cov khau khau), koj yuav tsum tsis txhob kov cov khoom siv hluav taws xob ncaj qha nrog koj txhais tes.
