In metallurgical steel production, sintering main exhaust fans consume significant energy, and traditional starting methods suffer from high inrush current and severe energy waste. Nancal Electric retrofitted a steel plant's sintering main exhaust system with medium voltage VFDs, achieving soft start and variable frequency speed regulation in a "two-drive-two" configuration with manual mutual backup. Committed to energy savings and customer cost reduction, we are always taking action.
The hydrostatic test for the reactor coolant system of Unit 3 at the Haiyang Nuclear Power Plant was successfully completed. This test represents the first key milestone in the commissioning phase for Unit 3. The cold test verified that the four reactor coolant pumps (RCPs) for Unit 3, along with their supporting localized RCP Drives supplied by Nancal Electric, operated normally, marking a successful first attempt.
2025 was a year of deep technical cultivation and steady advancement for Nancal Electric. Guided by the spirit of engineers, we drove continuous innovation in power electronics and electrical drives, delivering reliable products and solutions to help build a clean, low-carbon, safe, and efficient energy ecosystem.
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”.
