Product Overview
GRM6-40.5 Series imhando itsva SF6 gasi-insulated compact switchgears. Circuit breaker, disconnectors, uye zvimwe zvikamu zvakavharirwa mu3mm-gobvu simbi midziyo yakazadzwa ne low-pressure SF6 gasi. Saka, iyo midziyo ndeye compact, yakavimbika, uye yakachengeteka; yemahara yekukanganisa kwezvakatipoteredza, kuchengetedza kwemahara uye hupenyu hurefu hwebasa, nezvimwe.
GRM6-40.5 Series switchgears inokodzera kudzora, kudzivirira uye kutarisa kwe40.5 kV, matatu-chikamu, single busbar yemagetsi system, inoshandiswa zvakanyanya mukugadzira makambani, migodhi, nezvimwe.
