Ama-insulator we-ceramic insulator ayizinto ezibalulekile emkhakheni wobunjiniyela kagesi, ikakhulukazi kumongo wokudluliswa kwamandla nokusatshalaliswa. Lawa ma-insulator aklanyelwe ukuxhasa ulayini wamandla ongaphezulu, ahlinzeka ngamandla emishini ngenkathi kuqinisekisa ukuhlukaniswa kukagesi. Umsebenzi wabo oyinhloko ukuvimbela ukugeleza kwamanje kagesi kuzakhiwo ezisekelayo, njengokuthola
