Lei Qiaolin, a member of the Communist Party of China, holds a master's degree and serves as the head of the Special and Protective Components Division at Zhenhua Yunke. It has successively won honorary titles such as model worker of Guizhou Province, "Innovation Expert" of Guizhou National Defense Trade Union, the third prize of Guizhou Science and Technology Progress Award, the third prize of China Electronics "Science and Technology Progress Award", "Excellent Craftsman of Resistance Potentiometer Branch of Component Industry Association", "model worker of China Zhenhua" and "Excellent Scientific and Technological Worker".

For many years, Lei Qiaolin has been deeply involved in the research and design of small-scale fuse technology. With independent innovation, he breaks down technological barriers and promotes the leap of fuse core technology from "following" to "leading". He has delivered a brilliant answer in the fields of technological innovation, industrial development, and talent cultivation, vividly demonstrating the responsibility of "success does not have to be mine, success must be mine" through practical actions.

Breaking through technological barriers and illuminating the light of technology with innovation

Faced with the dilemma of long-term dependence on external factors for core technology of small fuses, Lei Qiaolin led a team to focus on the field of small fuses, presided over 4 national and provincial scientific research projects, authorized 3 invention patents, and formulated 13 high-tech electronic standards for filing, breaking through technical barriers and igniting the flame of hope on the road of technological self-reliance and self-improvement with "small fuses" one by one, pushing "Made in China" to "Made in China", demonstrating the mission and responsibility of serving the country with science and technology.

In the technical breakthrough project of small fuse production line, he led the team to overcome difficulties and built the first high-quality small fuse production line in China, solving technical barriers and achieving international advanced technical level. Successfully developed surface mounted fuses, solving the industry challenges faced by high current fuses.

With the rapid development of commercial satellites, new requirements have been put forward for miniaturization, low cost, and high reliability of fuses. He led the fuse team to develop an all solid state tubular fuse with a volume only 1/10 of the benchmark product, which has obvious performance advantages and solves the problem of continuous discharge of traditional tubular fuses after melting under low air pressure, high voltage, and high current. At present, the product has been approved by the customer and has obtained market orders. It is expected to become the first all solid state tubular fuse in the commercial aerospace field in the future.

02 Building an industrial highland, leading the forefront of the industry with ingenuity

Lei Qiaolin takes it as his responsibility to serve the country through industry and has written a legend from a pursuer to a leader. Relying on the advantages of electronic materials and electronic components industry possessed by Zhenhua Yunke, Lei Qiaolin led the team to develop more than 10 high-performance fuses. Among them, surface mounted fuses have made breakthrough progress in maximum rated current, helping Zhenhua Yunke to become a leading enterprise in China with multiple fuse models, complete specifications, high quality levels, wide application models, and high market share. This not only enhances the company's market competitiveness and corporate image, but also drives the progress and development of the entire fuse industry. Over the course of five years, he led the business unit to achieve a year-on-year increase of 340% in the company's output value, becoming a strong engine for regional economic takeoff.

03 Nurture the fertile soil of talents, activate the source of innovation through inheritance

Without talent, innovation is like water without a source. Adhering to this belief, Lei Qiaolin regards talent cultivation as the focus of technological breakthroughs, actively promotes the construction of an "industry university research application" ecology, and implements a three in one model of school enterprise cooperation, skills training, and innovative studio construction, injecting inexhaustible power into the company's high-quality development.

We have conscientiously implemented the deployment requirements of our superiors and established a deep cooperation mechanism with Guizhou Electronic Information Vocational and Technical College. Through the "school enterprise cooperation, industry education integration" model, we have led our team to extend the classroom to the front line of production, forming a closed-loop training system of theoretical teaching, workshop training, and project practice. We have trained 41 senior technicians and opened up the "last mile" of school enterprise joint education.

Faced with the challenges of a younger team and a lack of experience, Lei Qiaolin actively practices the "teacher apprentice" mechanism and adheres to the learning and exchange concept of "the elderly impart old experiences, and the new convey new perspectives". In the past three years, he has trained 1 technician, 26 senior engineers, 3 senior engineers, and 10 engineers, helping 3 employees win first, second, and third prizes respectively in the 2022 Guizhou Skills Competition. Among them, one post-90s skilled backbone was awarded the title of "Guizhou Technical Expert". The four-star "Model Worker and Craftsman Talent Innovation Studio" in Guizhou Province, led by him, has become an "incubator" for industry technological innovation through technological breakthroughs. Over the past five years, it has attracted and trained 18 high-end talents with master's degrees to settle in Guizhou, forming a virtuous cycle of "cultivating talents through projects and retaining talents through achievements".

From the "seedling cultivation plan" of industry education integration to the "craftsman inheritance" of master apprentice relay, and then to the "talent magnetic field" of innovation studio, Lei Qiaolin interprets through practice that "technology is the primary productive force, talent is the primary resource, and innovation is the primary driving force".

The story of Lei Qiaolin is a microcosm of countless frontline technology workers at Zhenhua Technology, and a continuation of the spirit of craftsmanship. He leveraged "big industries" with "small devices" and achieved "big dreams" with "small teams". Through the integration of scientific research, industry, and education, he demonstrated the responsibility and glory of frontline workers with practical actions. In the future, he will continue to practice the spirit of model workers, focus on the company's main responsibilities and businesses, and continue to explore beneficial fields such as commercial aerospace, low altitude economy, and energy storage, contributing actively to the high-quality development of Zhenhua Technology and Zhenhua Cloud Technology.
