Recently, entrusted by the Gansu Provincial Department of Industry and Information Technology, the Gansu Provincial Institute of Science and Technology Information invited relevant experts to form an expert review group to conduct a strict review of the six new products independently developed by Changkai Factory Group. Among them, two technical achievements reached the international advanced level and four reached the domestic leading level. This achievement marks that the company has made a major breakthrough in the field of technological innovation and further consolidated its leading position in the industry.

During the review process, the expert group strictly reviewed the product development report, technical standards, test reports and other relevant materials with a rigorous and scientific attitude. After full discussion and questioning, the expert group unanimously agreed that the company's i-AY6-12 AC metal-enclosed switchgear and control equipment and EVH9-12 indoor high-voltage AC vacuum circuit breaker have excellent performance in technological innovation, performance indicators, product quality and other aspects, and the overall technology has reached the international advanced level; KYN28A-12 AC metal-enclosed switchgear and control equipment (capacitor cutting), LNG-40.5 indoor high-voltage AC sulfur hexafluoride circuit breaker and other four items have reached the domestic leading level.

It is reported that the i-AY6-12 AC metal-enclosed switchgear and control equipment and EVH9-12 indoor high-voltage AC vacuum circuit breaker, which were awarded as international advanced products, have a quality assurance classification of QA1, seismic classification class I, and safety level 1E. They have the capabilities of "high standards, high quality, and high reliability", fully meet the technical requirements of my country's nuclear power switchgear, and achieve "domestic substitution", providing strong support for the country's nuclear power to go overseas. So far, the company's nuclear-grade switchgear has repeatedly achieved outstanding results in the field of nuclear power, and has successfully won bids for 10 units of nuclear island projects and 8 units of conventional island and BOP projects. It has successfully occupied the first place in the market share of medium-voltage cabinets used in the domestic nuclear power industry. Among them, the Zhangzhou Nuclear Power Unit 1 project has been successfully put into commercial operation, and all performances have met the high-quality standards.
