Vacuum interrupter e lauiloa foi o le vacuum switch tube, o le vaega autu lea o le eletise eletise maualuga.O lana galuega autu o le tipi ese lea o le arc e ala i le faʻaogaina lelei o le vacuum i le eletise maualuga ma taofiofi vave le taimi nei e aloese ai mai faʻalavelave ma lamatiaga.E masani ona faʻaaogaina i le eletise eletise eletise ma le tufatufaina atu o faiga faʻatonutonu, faʻaaogaina foi i metallurgy, mining, petroleum, vailaʻau vailaʻau, nofoaafi, faʻasalalauga, fesoʻotaʻiga, fale gaosi oloa maualuga faʻavevela faʻavevelaina faiga faʻafefe.O loʻo faʻaalia i le faʻaolaina o le malosi, faʻasaoina o meafaitino, puipuiga o le afi, faʻamaoniga o le pa, laʻititi laʻititi, ola umi, tau maualalo o le tausiga, faʻatuatuaina le faʻaogaina ma le le faʻaleagaina.Vacuum interrupter e mafai ona vaevaeina i ni ituaiga eseese, tasi mo le matagaluega-breakers ma le isi mo ki uta, mo contactor, mo recloser.
O lenei faasologa o oloa o loʻo faʻapipiʻiina e ala i le faʻapipiʻiina i le taimi e tasi-taimi-conductive vaega matagaluega o vacuum interrupter ma fesuiaʻi i totonu o le epoxy resin mea insulation.O le pito i fafo o vacuum interrupter e le aafia i fafo environment.External insulation gafatia e le mafai ona aafia e. le efuefu, susu, manu laiti, condensation ma contamination.O le oloa e tele mea lelei, e pei o le malosi dielectric maualuga, malosi tetee tau faatinoga, tasi-taimi-ciecuit miniaturization, fausaga mausali, faatuatuaina maualuga ma le tausiga saoloto.
