The ZW32C-12 Outdoor High Voltage Vacuum Circuit Breaker adopts vacuum arc extinguishing technology, equipped with a permanent magnet operating mechanism (spring mechanism). It integrates micro-processing technology, modern network communication technology, and new switch manufacturing materials. With a rated voltage of 12kV and a frequency of 50Hz, this circuit breaker is suitable for three-phase AC outdoor power distribution systems. It is widely used in urban power grids as a sectionalizing or interconnection switch or in rural power distribution systems as an outdoor substation outlet switch. The ZW32C-12 breaker effectively replaces traditional reclosers, handling the breaking and making of load current and short-circuit current.
The ZW32C-12 Outdoor High Voltage Vacuum Circuit Breaker is suitable for various grid applications, including:
•Sectionalizing or interconnection switch in urban power grids
•Protection and control in rural power distribution systems
•Outlet switch in outdoor substations
1.Rated Voltage: 12kV
2.Frequency: 50Hz
3.Ambient Temperature: -40℃ to +55℃, daily temperature variation not exceeding 25K
4.Altitude: Not exceeding 2000m
5.Wind Speed: Not exceeding 35m/s
6.Pollution Level: Grade IV
7.Installation Location: Free from inflammable, explosive hazards, and chemical corrosion
