Iyi modhi inobatanidza mashandisirwo ekushanda pamwe neyedunhu breaker, yakarongedzwa zvakanaka, inotaridzika yakanaka uye compact.2.Iyi modhi inogona kushandiswa kazhinji, inokwanisa kuputsa uye kudzoreredza nekukurumidza kakawanda.3.Two marudzi ekuisa (yakagadziriswa kana kutamiswa) inosangana nezvinodiwa zvema switchgears akasiyana.(VS1) -12 iHV indoor vacuum circuit breaker inoshanda sechidziviriro nekudzora chikamu chemagetsi gidhi midziyo uye maindasitiri emagetsi emidziyo mumagetsi emagetsi akayerwa kubva pa7.2KV kusvika 12KV.Inosangana nezvinodiwa zveGB/T1984-2014 (AC HV circuit breaker) uye JB355-1996 (3.6KV-40.5KV indoor AC HV vacuum circuit breaker).Inogona kushandiswa mune switchgears yeKYN28(GZS1), XGN uye GG-1A.
Muchina wekushandisa imhando yemagetsi yakachengetwa isina rwendo ine yakazvimirira kuvhura uye kuvhara zvisinei nekuita kwemushandisi.Iyo yekushandisa michina inoshandiswa zvakanyanya mune ese VD4-R akateedzana maseketi-mabreaker ane frontal control.
Iyo yedunhu-inopwanya inogona kudzorwa kure kana yakashongedzwa neakazvitsaurira magetsi accessories (gearmotor, kuvhura uye kuvhara kuburitswa).
Mashandisirwo ekushandisa, mapango matatu uye masensa azvino (kana akapihwa) akaiswa pasimbi isina mavhiri.Chivakwa chacho chinonyanya kusimba, chakasimba uye chehuremu hushoma.
VD4-R series circuit-breaker with lateral operating mechanisms are life-long sealed pressure devices.(Mitemo IEC 62271-100)
