Isiphazamisi se-vacuum(VI) sokuvala kabusha okusetshenziselwa ikakhulukazi izikhungo zesiteshi esincane kanye negridi yamandla emkhakheni wamandla. Lolu chungechunge lwe-vacuum interruper luthatha imvilophu ye-ceramic insulating, inkomishi ebunjwe inkambu kazibuthe ye-axial, isakhiwo sesivikelo esiphakathi nendawo, i-Cu-Cr yokuxhumana. izici zomthamo omkhulu wokushintsha, amazinga aphezulu okufaka i-insulating, amandla aqinile okucisha i-arc kanye nempilo ende, njll.I-vacuum recloser ehambisana nayo inezinzuzo zokulungisa kalula, akukho bungozi bokuqhuma, akukho ukungcoliswa nomsindo ophansi, njll.,futhi ingakwazi zisetshenziswe kabanzi emandleni kagesi, emishinini, ensimbi, emnyangweni wamakhemikhali kanye nezimayini, njll., ukulawula nokuvikela uhlelo lokudlulisela nokusabalalisa.
