Khoom Taw Qhia:
Ib kab ncej insulator yog ib qho insulator ntawm feem ntau columnar zoo, muaj txhais tau tias rau ncaj qha thiab nruj mounting. Nrog rau qhov hloov pauv tau los ntawm tus pin insulators thiab cov insulators feem ntau yog siv los tiv thaiv thiab txhawb cov conductors.Peb tsim cov insulators raws li cov qauv ntawm IEC60383, ANSI, BS thiab cov neeg siv khoom tshwj xeeb.
