Advancing Full Resumption of Work and Production; Accelerating Post-Pandemic Product Delivery

The COVID-19 pandemic not only delayed the resumption of work and production but also introduced immense challenges. Amidst the ongoing, complex epidemic prevention and control situation, Taihao Shendian has mobilized its entire workforce to ensure production schedules are met while actively implementing necessary health and safety measures. Company leadership formulated effective resumption plans while simultaneously driving production and making up for lost time. By overcoming numerous obstacles and rigorously managing safety and quality risks, the company has remained steadfast in its commitment to serving its customers. 

These deliveries were completed under extremely challenging pandemic conditions. After resuming operations, Taihao Shendian prioritized risk control and employed flexible strategies to organize a safe, orderly return to work, ensuring stable production. Frontline employees worked overtime to overcome hurdles such as supply chain disruptions and transportation restrictions, ultimately achieving successful delivery.

 This batch consists of large and medium-sized, high-speed, high-efficiency industrial asynchronous motors—products that have historically presented significant manufacturing challenges within the industry. High-speed rotation often generates vibration and noise that compromise stability, while the complex manufacturing processes make the production of copper-bar rotors particularly difficult. Leveraging a mature, reliable design system, advanced manufacturing techniques, and 70 years of experience in producing large and medium-sized high-voltage AC motors, Taihao Shendian overcame multiple technical hurdles to meet all specified performance metrics.

For this product series, technical solutions were deeply optimized across the entire lifecycle—from electromagnetic calculations, structural design, and ventilation/temperature-rise analysis to manufacturing processes and testing standards. By precisely designing the motors and controlling material costs to eliminate waste, the company delivers highly cost-effective products. Furthermore, key materials are sourced from industry-leading suppliers, ensuring stability and reliability while significantly reducing copper and iron losses. This effectively boosts motor efficiency, meeting the Grade 1 and Grade 2 energy efficiency standards set by the national GB/T 30254 standard, thereby enabling energy conservation, emission reduction, and low-carbon, eco-friendly performance in practical applications.

This series of motors was developed using advanced international industry technologies, ensuring that their electrical performance meets leading domestic standards; key technical specifications—such as torque and efficiency—surpass those of comparable domestic products. In applications across sectors including metallurgy, petroleum, petrochemicals, chemicals, iron and steel, cement, mining, water supply, and power generation, the annual comprehensive electricity saving rate exceeds 5%–8%.
