Isiphazamisi se-vacuum esaziwa nangokuthi i-vacuum switch tube, ingxenye eyinhloko yokushintshwa kwamandla kagesi aphezulu.Umsebenzi wayo oyinhloko ukunqamula i-arc ngokusebenzisa i-vacuum enhle kakhulu kusekethe kagesi kagesi kanye nokuvimbela amandla amanje ngokushesha ukugwema izingozi nobungozi.Isetshenziswa kakhulu ohlelweni lokudluliswa kwamandla kagesi kanye nohlelo lokulawula ukusatshalaliswa, luphinde lusetshenziswe kwezensimbi, izimayini, i-petroleum, imboni yamakhemikhali, izitimela, ukusakaza, ukuxhumana, uhlelo lokusabalalisa amandla kagesi okushisa okuphezulu kwezimboni.Ibonakala ngokonga amandla, ukonga impahla, ukuvimbela umlilo, ubufakazi bokuqhuma, umthamo omncane, impilo ende, izindleko eziphansi zokunakekela, ukusebenza okuthembekile nokungangcolisi.Isiphazamisi se-vacuum singahlukaniswa ngezinhlobo ezimbalwa, enye ngeyeziqhekezi-sekethe kanti enye ngeyokushintsha komthwalo, okothintana naye, okokuvala kabusha.
Lolu chungechunge lwemikhiqizo lubunjwa ngokushumeka ngesikhathi esisodwa izingxenye zesekethe eziqhutshwa kanye kanye zesiphazamisi se-vacuum bese zishintshela ku-epoxy resin material insulation. uthuli, umswakama, isilwane esincane, ukujiya kanye nokungcoliswa. Umkhiqizo unezinzuzo eziningi, njengamandla aphezulu e-dielectric, ukusebenza okuqinile kokumelana nesimo sezulu, i-miniaturization yesikhathi esisodwa-ciecuit, isakhiwo esiqinile, ukuthembeka okuphezulu nokugcinwa mahhala.
