ZW8-12 Series yekunze yakakwira voltage vhoriyamu redunhu mudariki ndiyo huru switch michina yeakavhenekerwa voltage 12KV, matatu matanho AC50Hz system, switch on / off kurodha zvazvino, pamusoro-pari zvino, uye pfupi dunhu mumaruwa kana mumaguta emagetsi network. Chimiro chebhureki ndechechikamu-chetatu chakaunganidzwa mutangi, matatu-chikamu vacuum arc-yekudzimisa kamuri yakavharirwa musimbi tangi, kuputira zvinhu pakati pezvikamu uye chikamu kune yega yega inogadzirwa neSMC, kuita kwakavimbika, uye yakakwira yekudzivirira simba.

ZW8-12G ine ZW8-12 breaker uye isolator, inonzi yakasanganiswa breaker, inogona kushandiswa senge chikamu.

Iyo yekushandisa mashini yeiyi yakateedzana breaker ndeye CT23 yechirimo yekuchaja mashini, mota kana ruoko rwekushandisa mhando
