ZW32 Outdoor AC high voltage vacuum circuit breaker
Product Overview:
The ZW32-12 Outdoor AC High Voltage Vacuum Circuit Breaker is a critical piece of power distribution equipment designed for medium voltage applications, with rated voltages of 12kV, 24kV, and 40.5kV and operating at three-phase AC 50Hz. This circuit breaker is primarily used to interrupt and close load current, overload current, and short-circuit current within the power system. It is particularly suitable for protection and control in power distribution systems of substations, industrial and mining enterprises, and rural power grids that require frequent operation.
Key Features:
• Compact and Lightweight Design: The breaker is designed to be small in size and light in weight, making it easy to install and maintain.
• Anti-Condensation: Built to withstand harsh environmental conditions, the breaker effectively prevents condensation, ensuring reliable operation even in humid or dirty environments.
• Maintenance-Free: The circuit breaker is designed for long-term operation with minimal maintenance, making it cost-effective and reliable.
Application Environment:
• Substations: Ideal for the protection and control of power distribution systems in substations.
• Industrial and Mining Enterprises: Provides reliable protection for power systems in industrial and mining environments.
• Rural Power Grids: Especially suitable for rural power grids that require frequent operations and reliable performance.
Operating Conditions:
• Voltage Ratings: Available in 12kV, 24kV, and 40.5kV versions to meet different application needs.
• Frequency: Operates at 50Hz, suitable for standard power distribution systems.
• Environmental Adaptability: Can operate effectively in harsh weather conditions, including high humidity and pollution levels.
Usage Considerations:
• Ensure the breaker is installed in a location that meets the specified environmental conditions.
• Regular inspections are recommended to ensure continued reliable operation, although the breaker is designed to be maintenance-free.
• Follow all safety guidelines during installation and operation to avoid any risk of electrical hazards.
