Incazelo emfushane:

I-ZN12-40.5 series Indoor High Voltage VCB, iyiswishi yokushintsha i-vacuum ene-voltage elinganisiwe engu-40.5KV, i-AC enezigaba ezi-3 engu-50HZ. Ingeniswe ubuchwepheshe be-3AF obuvela e-Siemens Germany. I-VCB enjalo, ukusebenza kanye neswishi kuyingxenye ebalulekile. Isakhiwo sokusebenza singamandla agcinwe yintwasahlobo ezinikele, singasebenza nge-AC, DC, noma ngesandla. Isakhiwo se-VCB enjalo silula, sinamandla okuhle okuphuka, isikhathi eside sokuqina, umsebenzi obanzi, awuyingozi yokuqhuma. Ukulungiswa okulula. Ifanele ukulawula noma ukuvikela iswishi yesiteshi sikagesi, igridi yamandla yasemadolobheni kanye nesiteshi esincane, ikakhulukazi ifanele izindawo ezidinga umthwalo wokuphuka kanye nokusebenza kokuphuka njalo.
