ZW20-12 panja HV vacuum circuit breaker ndi 3-phase AC 50Hz 12kV zida zosinthira panja.
♦ Njira yoyika: yokwera;
♦ Mtundu wa pole: mzati wophatikizika;
♦ Kugwiritsa ntchito: panja 12kV substation, malo opangira magetsi.
♦ Mtundu wa ntchito: Buku, magetsi, mphamvu yakutali.
Mikhalidwe Yachilengedwe
♦ Kutalika:
♦ Kutentha kwa mpweya: -40°C~ +40 ° C; kutentha kwa tsiku ndi tsiku kupitirira 25 ° C;
♦ Kuthamanga kwa mphepo
♦ Mulingo wonyansa: IV;
♦ Malo oyika: Palibe moto, ngozi ya kuphulika, dzimbiri la mankhwala kapena kugwedezeka kwakukulu;
♦ Kuchuluka kwa chivomezi:
