Isiphazamisi sevacuum ekwabizwa ngokuba yityhubhu yokutshitsha, yeyona nto iphambili yokutshintsha kwamandla ombane aphezulu.Umsebenzi wayo ophambili kukuqhawula i-arc nge-insulation egqwesileyo ye-vacuum kwisekethe yombane ophezulu kunye nokuthintela okwangoku ngokukhawuleza ukunqanda iingozi kunye nobungozi.Isetyenziswa ikakhulu kuthumelo lwamandla ombane kunye nenkqubo yolawulo lokusasaza, ikwasetyenziswa kwisinyithi, imigodi, i-petroleum, ishishini lemichiza, oololiwe, usasazo, unxibelelwano, inkqubo yokuhambisa amandla ombane wokufudumeza okuphakamileyo.Ibonakaliswe ngokugcinwa kwamandla, ukugcinwa kwezinto eziphathekayo, ukuthintela umlilo, ubungqina bokuqhuma, umthamo omncinci, ubomi obude, iindleko zokugcinwa okuphantsi, ukusebenza okuthembekileyo kunye nokungangcolisi.Isiphazamisi sevacuum sinokwahlulwa ngokweendidi ezininzi, enye yezozaphuli-sekethe kwaye enye yeyokutshintsha komthwalo, yeyokuqhagamshelwa, yokuvala kwakhona.
Olu chungechunge lweemveliso lubunjwa ngokufakela ngaxeshanye iinxalenye zesekethe zexesha elinye ze-vacuum interrupter kwaye zitshintshele kwi-epoxy resin material insulation. uthuli, ukufuma, isilwanyana esincinci, ukujiya kunye nokungcoliswa. Imveliso ineenzuzo ezininzi, njengamandla aphezulu e-dielectric, ukusebenza okuqinileyo kwemozulu, i-mini-time-ciecuit miniaturization, isakhiwo esiqinileyo, ukuthembeka okuphezulu kunye nokugcinwa simahla.
