High-Speed Breaking: Ita ya yi waɗannan da ya fiye da current ta short-circuit a haguji na farko na first power frequency half-wave na short-circuit current, musamman idan current ta short-circuit bai shiga zuwa peak. Tsari na total breaking shine 2-5 ms, wanda yake da yawan 10-20 karfi da circuit breakers.
Current-Limiting Breaking: Ita tana faru da limiting current ta short-circuit 1ms bayan an yi short-circuit, kuma ya zama limiting current ta short-circuit zuwa 15%-45% na expected value.
High Breaking Capacity: Rated prospective short-circuit breaking current shine 63-200kA, amma rated short-circuit breaking current na circuit breakers da ake bi da shi a lokacin da yanzu maimakon 40.5-50kA.
Built-in Rogowski Current Sensor: Ita na da accurate measurement, fast response speed, da kuma za a iya faɗi shi a separate phases ko a kiyaye.
High Reliability: Wanda tana da competitive advantage wata shine superior reliability. Special designs and craftsmanship sun haifar da high reliability na product, wanda ya zama tested and well-received a field.
Flexible Cabinet Arrangement: Switchgear tana iya faɗi shi a combined or independent manner. A cikin, za a iya fitce da one or two sets of disconnectors don requirements na design institute, ko kuma connected in series with vacuum switches. Ita na da five-prevention interlocking, flexible operation, da kuma convenient for spare parts replacement.
