ZW32-12 outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor power distribution equipment with rated voltage of 12KV and three-phase AC 50Hz. It is mainly used to break and close the load current, overload current and short circuit current in the power system. It is suitable for protection and control in substation and industrial and mining enterprise substation systems, and places where rural power grids operate frequently.
The circuit breaker has the characteristics of small size, light weight, anti-condensation and maintenance-free, and can adapt to harsh weather conditions and dirty environments.Standards compliant:
GB1984 "AC high voltage circuit breaker"
GB11022 "Common technical requirements for high-voltage switchgear and control equipment standards"
GB311.1-6 "Insulation coordination of high voltage power transmission and transformation equipment"
GB763 "Communication of AC high voltage electrical appliances during long-term work"
BG2706 "Test Method for Dynamic and Thermal Stability of AC High Voltage Apparatus"
GB3309 "Mechanical test of high voltage switchgear at room temperature"
DL/T593 "Technical Conditions for Common Ordering of High Voltage Switchgear"
