In August 2003, the company signed a contract for the manufacture of 750 kV power transmission and transformation equipment with State Grid Corporation, providing reactor products for the world's highest altitude Qingting Guanting to Gansu Lanzhou East Transmission Substation Demonstration Project. More than 100 technical experts involved in research and development have overcome more than 80 world-class technical problems in product design, process and inspection, and achieved the goal of “one-time manufacturing success, one-time installation success, one-time operation successâ€. Received 13 national patent technologies.
The company has always insisted on independent innovation in the research and development of key technologies. The coil is the "heart" of the transformer. In the product development, the technicians adopt a new design concept based on the introduction of foreign technology, which effectively improves the reliability of the product, and has the characteristics of energy saving and material saving, and improves the work efficiency.
It is understood that the company has developed rapidly since the reorganization of TBEA. In the past seven years, they have been aiming at the world's leading level and committed to the development of high-end products in the field of power transmission and transformation. The output value increased from 100 million yuan in 2000 to 2.5 billion yuan last year, and net assets increased by 502 times. The annual tax payment was raised from 7.92 million yuan at that time to 135 million yuan last year. The company has invested 1.2 billion yuan in three large-scale technological transformations.
Focusing on the medium and long-term development plan of the country, the company has undertaken the major scientific research projects of the “10th Five-Year Plan†and “Eleventh Five-Year Planâ€, and mastered the development technology of 750 kV and 1000 kV transformers and reactors representing the highest level of power transmission and transformation equipment in the world. And the core technology of independent intellectual property rights such as the one million kilowatt generator main transformer. It has provided a number of domestic first (set) product technologies and services for major national projects such as China's Three Gorges Project, West-East Power Transmission Project, and UHV AC Demonstration Project, and has become a backbone enterprise in China's power transmission and transformation field. At present, it has more than 100 core patent technologies and proprietary technologies at home and abroad, and nearly 100 invention patents.
It is reported that before this, the company's 750 kV reactor was awarded the "China Machinery Industry Special Award". Currently, they are working on the development of a 1700 kV transformer that represents the highest level of technology in the world.
The characteristics of children's book printing services are high printing quality, bright colors, full patterns, clear fonts, easy to read, and in line with children's psychological and cognitive characteristics. Attention should be paid to the use of environmentally friendly printing materials during the printing process to ensure the health and safety of children.
Children's book printing services usually include design, plate making, printing, binding, and other links. In the design process, it is necessary to consider factors such as children's age, gender, hobbies, and other factors to design patterns and formats that meet children's aesthetic needs. In the plate making process, high-quality printing plates should be used to ensure the restoration of colors and patterns. In the printing process, high-quality printing equipment and environmentally friendly printing materials should be used to ensure the quality and safety of printed products. In the binding process, it is necessary to choose a binding method suitable for children to ensure the durability and ease of reading of the book.
Recently, the project of “Key Technology Research, Equipment Development and Engineering Application of 750 kV AC Transmission and Transformationâ€, which was developed by TBEA Hengyang Transformer Co., Ltd., won the “First Prize of National Science and Technology Progress Award†issued by the State Council in 2007. This honor shows that the Hengchang ultra-high pressure technology has entered the ranks of the world's advanced level.
