Product Description
ZN85 33kV 1250AIndoor Vacuum Circuit Breaker:
ZN85 indoor high-voltage alternating-current vacuum circuit breaker ine frequency ye50Hz uye rated voltage ye40.5kV.Inoshanda kune emagetsi ekudzora uye kudzivirira kwemidziyo yemagetsi mumaindasitiri uye emigodhi mabhizinesi, magetsi emagetsi uye zviteshi, kunyanya kunzvimbo dzinoda kushanda nguva zhinji.Inogona kugadziriswa mune switch cabinet kana kuiswa pa handcart.
Nekuita kwakagadzikana uye kuisirwa kuri nyore, ndiyo yakanakisa sarudzo yekutonga nekudzivirira kweakakwira-voltage magetsi ekufambisa uye masisitimu ekuparadzira.
