As well as the processing facilities, the testing facilities are also very important to the quality control of the breaker. In the
manufacturing process of VB, from incoming material quality control to the final inspection and testing, every step is strictly
calibrated and tested by means of testing facilities. For every embedded pole, before it goes into the breaker assembly line, it s
go through following inspections and testing carried out in factory:

除了生产过程的设备，测试设备对于断路器的质量控制也非常重要。 在 VB 的制造过程中，从进料的质量控制到最终的检验和测
试，每个步骤均通过测试设备进行严格的校准和测试。对于每个固封极柱，在进入断路器装配线之前，应经过以下工厂检查和测
试：

• X-ray inspection X 光检查

• Power frequency withstand voltage test 工频耐压试验

• Partial discharge measurement 局部放电测量

• Extremely high and low temperature impulse test 高、低温冲击试验

Before delivery, the following tests and inspections will be done for VB embedded pole vacuum circuit breaker in factory by
means of advanced testing equipments:
