Product Description

product description:
ZW32-12M High Voltage Vacuum Circuit Breaker
Our outdoor vacuum circuit breaker is a high - performance device specifically designed for outdoor power systems, aiming to ensure stable and reliable power distribution.
It adopts advanced vacuum arc - extinguishing technology, which can extinguish the arc in an extremely short time and effectively cut off the circuit. This not only greatly improves the interrupting capacity but also reduces the impact on the environment. The circuit breaker has excellent mechanical and electrical life, reducing the need for frequent maintenance and significantly lowering the operating costs.
In terms of performance, it has outstanding insulation performance and can operate stably in harsh outdoor environments. Whether it is high temperature, humidity, strong wind or sand, it will not affect its normal operation. Its fast opening and closing speed can respond to power failures instantly and quickly cut off the circuit to ensure the safety of the power system.
Our outdoor vacuum circuit breaker is suitable for various outdoor power scenarios, such as substations, distribution networks, industrial power facilities, etc., providing reliable protection and control for power projects of different scales. Choosing this product means choosing efficient, safe and long - lasting power protection.

Product Features:
1.Excellent Arc - extinguishing Capability: The ZW32 - 12M adopts advanced vacuum interrupter technology. By taking advantage of the principle of rapid arc diffusion and extinction in a high - vacuum environment, it can cut off short - circuit current up to 31.5kA in an extremely short time (usually less than 50ms). This greatly improves the rapid response ability of the power system in case of faults and effectively ensures the safe and stable operation of the power grid.
2.Superior Insulation Performance: The circuit breaker has a reasonable insulation structure design and uses high - performance insulation materials. Under the rated voltage of 12kV, its 1 - minute power - frequency withstand voltage can reach 42kV, and the lightning impulse withstand voltage reaches 75kV. This ensures stable and reliable operation under various complex weather conditions, such as heavy rain, sand and dust, and condensation, and avoids power accidents caused by insulation problems.
3.Reliable Mechanical Performance: It is equipped with a high - strength alloy shell and a precise mechanical transmission mechanism. After strict mechanical life tests, the number of operations can reach more than 10,000 times, and the opening and closing speeds are stable. The closing time does not exceed 100ms, and the opening time does not exceed 60ms. It can meet the needs of frequent operations, reduce the frequency of maintenance, and lower the operation and maintenance costs.
4.Strong Environmental Adaptability: Specifically designed for harsh outdoor environments, its protection level reaches IP67, which can completely prevent dust intrusion and remain unaffected even when immersed in water at a depth of 1 meter for 30 minutes. At the same time, it can operate normally within the extreme temperature range of - 40ºC to + 70ºC. Whether in the frigid northern regions or the sweltering southern areas, it can operate stably.
