Recently, the 9th National Electrical Technology Conference for Petroleum and Chemical Industries was successfully held in Chengdu. The event was hosted by the China Association of Mechatronics Technology and Application and co-organized by Shanghai Nancal Electric Co., Ltd., among other companies. Petrochemical production is a continuous process that demands extremely high equipment reliability. Nancal Electric has achieved multiple domestic "first-of-its-kind" breakthroughs in sectors with stringent reliability requirements, including military, nuclear power, chemical, mining, and energy storage, showcasing its technological leadership and extensive engineering expertise.
In a chemical gasification plant, the propylene compressor plays a crucial role with high demands for operational reliability and stability. Equipment failure can have severe impacts on the plant and downstream production. The plant originally used an imported medium-voltage drive, but its failure rate has been increasing. A significant failure, especially one that cannot be quickly repaired, could halt gasification operations, disrupt downstream production, and lead to substantial economic losses. After extensive research and technical discussions, the user selected Shanghai Nancal’s medium-voltage drive for hot standby, enabling the redundant automatic switching technology of NC HVVF to resolve issues caused by failures in the original imported drive and ensure uninterrupted production.
Recently, “The First Employee Skill Competition of Nengtuan Electric” was successfully concluded in Lingang Manufacturing Base, which aimed to further enhance the overall quality of the company's manufacturing and testing operations and motivate employees to refine their professional skills. A good product should be well-designed and well-manufactured, while a great product necessitates skilled craftsmen. Welding each circuit board, installing each power cell and testing each complete machine set are the ultimate expressions of our philosophy “Quality Achieves Customer Value”.
Recently, following independent application, recommendation, expert evaluation, and public announcement in accordance with government guidelines, Shanghai Nancal Electric Co., Ltd. has been officially granted the title of 2023 Shanghai Science and Technology “Little Giant” Enterprise.
Recently, according to relevant government documents, after independent declaration, qualification examination and government publicity, Shanghai Nancal Electric Co., Ltd. was officially approved as a National Specialized and Sophisticated "Little Giant" Enterprise. The certification work is organized by the Ministry of Industry and Information Technology of the People's Republic of China. Being identified as a National Specialized and Sophisticated "Little Giant" Enterprise means that the enterprise is located in the core field of industrial foundation and the key link of the industrial chain, with outstanding innovation ability, mastery of core technology, high market share in niche markets, good quality and efficiency, and meets all the requirements of six aspects of specialization, refinement, specialization, newness as well as industrial chain support and leading products.
Demands: A single module failure does not cause the inverter stopped. NANCAL Electric Solution：Neutral piont shifting technology of power cell bypass.MV drive will be bypassed automatically and keep running normally, when the faults of one cell exists. If compared with traditional bypass technology
Recently, Nancal Electric won the bid for a megawatt-level high-speed PMG four-quadrant VFD project.
Storage is an energy infrastructure integrating the functions of seasonal peak regulation, emergency gas supply and national energy strategic reserve. As a key equipment supplier of compressor units, Nancal Electric has excellent on-site service technology and fast response, which has been highly praised by Petrochina Southwest Oil and gas Field Huangcaoxia Gas Storage Construction Project Department and Sichuan Huacheng Supervision Company.
Nancal HVVF series drives can be used in constant torque control such as conveyor. The key control performance is to realize the coordination between multi-motors.
