Nzvimbo inoshanda: (Inokodzera nzvimbo dzinowanzo shandiswa negedhi remagetsi rekumaruwa)
1.Industrial.
2.Masimba emagetsi.
3.Substations.
12kV 1250A Breaker Advantages
1.Iyo ine yakapetwa yakavhurika dunhu uye nekukurumidza reclose kugona.
2.Inoenderana neyenyika GB1984 "High voltage alternating current circuit breaker".
3.Inoenderana nehunyanzvi chiyero JB3855“3.6 ~ 40.5 kV voltage vacuum circuit breaker outdoor exchange” uye yakakodzera IEC mwero.
