All products are subject to strict quality control (complete testing equipment system), including: 100% raw material #inspection, 100% production process inspection, and finished product sampling inspection. All according to or more than #IEC standards.
Our factory with nearly 20 years manufacturing experience. Not only every components is 100% inspected and warehoused, but also the mechanism is randomly inspected for life test. According to IEC standard, the service life of spring #operating mechanism is 10,000 times, and our company can basically reach more than 18,000 times. For your information, a lot of big brand choose the Operating Mechanism from us.
Now introduce 100% finished product testing:
finished product test items mainly include the following:
1. Circuit resistance;
2. Mechanical operating performance;
3. The accuracy of the Current Transformer & Voltage Transformer, because when the vacuum circuit breaker is combined with the FTU re-closer controller, it’s signal will be provided by the Current transformer & Voltage Transformer;
