Main Features:
The VJ24 Vacuum Circuit Breaker is suitable for 20kV power systems and employs an optimized modular spring-operated mechanism, featuring a rational design and a simple, reliable structure. It achieves maintenance-free operation, representing the new third-generation high-voltage vacuum circuit breaker. The vacuum interrupter and main conductive circuit are fixed using mature technology, ensuring stable and reliable insulation of the conductive circuit. The primary conductive main circuit uses a special structure and materials, significantly reducing heat generation, meeting temperature rise requirements, lowering power loss, and greatly improving reliability.

Jiangsu Senyuan Electric Co., Ltd. (hereinafter referred to as "Jiangsu Senyuan") is a modern management enterprise dedicated to the production, R&D, and sales of high and low-voltage complete equipment and switching devices. Since its establishment, Jiangsu Senyuan has secured a leading position in China's high and low-voltage switchgear industry through scientific management, advanced equipment, and sophisticated craftsmanship. It has been selected by ABB as an authorized manufacturer of high-voltage gas-insulated switchgear, a joint manufacturer of medium-voltage switchgear, and an authorized manufacturer of low-voltage switchgear in China.  

Currently, Jiangsu Senyuan owns multiple holding companies involved in fields such as new energy and smart electrical equipment. It has established sales and service branches and offices in numerous cities across the country, offering comprehensive business operations in R&D, production, sales, and service. As a high-tech enterprise, Jiangsu Senyuan holds multiple invention patents and utility model patents. It has been recognized as the "Most Influential Brand" by the China Electrical Equipment Industry Association and is a well-known trademark enterprise in Jiangsu Province.  

Jiangsu Senyuan is among the first in the industry to obtain ISO9001 quality management system certification, ISO14001 environmental management system certification, ISO18000 occupational health and safety management system certification, and CQC certification. It has also passed international certifications such as EU CE, Russian GOST, and Dutch KEMA.  

The company's product portfolio covers voltage levels of 0.4kV, 10kV, 20kV, and 35kV, including 400V low-voltage switchgear, 10kV air-insulated switchgear, 35kV gas-insulated switchgear, low-voltage molded case circuit breakers, low-voltage frame circuit breakers, low-voltage AC vacuum contactors, indoor high-voltage vacuum circuit breakers, outdoor high-voltage vacuum circuit breakers, and high-voltage vacuum contactor-fuse combination devices. These products are widely used in industries such as power, metallurgy, petroleum, chemical, coal, and urban construction. Leveraging superior technology and products, Jiangsu Senyuan has participated in numerous national key projects, including those for State Grid, China Southern Power Grid, Shanghai World Expo venues, and the Nuclear Industry Group. It has also collaborated with large domestic EPC contractors and system integrators to promote its products overseas.  

Jiangsu Senyuan has an independent R&D center staffed with a team of experienced engineers, including two Ph.D. holders and six postgraduates. The company places great emphasis on cooperation with renowned domestic and international enterprises, universities, and research institutes. It has established partnerships with leading companies such as ABB and GE and has successfully collaborated with Xi'an Jiaotong University, Southeast University, and Nanjing University of Science and Technology on projects such as intelligent high-voltage circuit breakers.
