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.
Nancal Electric successfully co-organized the 10th National Petrochemical Electrical Technology Conference 2026, where it delivered a technical presentation highlighting the core value of its high-reliability medium voltage drive solutions for energy saving, carbon reduction, and safe operation in the petrochemical industry. To date, the company has delivered over 200 water-cooling medium voltage drives. It also showcased its full-range series of air-cooling medium voltage drives covering all power ranges, emphasizing their high reliability, high energy efficiency, and flexible adaptability to support the green and low-carbon transition of the petrochemical sector.
Power grid fluctuations, harsh environmental conditions, dynamic load challenges… Faced with such complex on-site operating conditions, how does Nancal Electric's medium voltage AC drive, with its highly reliable system design, steadily withstand the "real test"?
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.

Demands: a single module fault should not result in the inverter shutdown NANCAL Solution: Power cell bypass with neutral point shifting technology Power cell bypass When a power cell (module) fails, MV drive can automatic bypass failure power cell and keep running without trip. If compared with tr
IndustryPetrochemical ObjectiveIn petrochemical industry, the one of main energy consuming equipment is the pump. The traditional drive solution can only run at the grid with fixed speed through the valve throttling to hydraulic coupling for speed regulation.
IndustryMiningObjectiveAccording to the environmental requirements, the offgas in coking plant needs to be desulfurized and denitrified before discharged.There are 4 induced draft fans on the customer site to guide the coking flue gas to the desulfurization tower and denitrification reactor.
From December 19, 2018 to December 21, 2018, sponsored by the Inverter Branch of the China Electrical Equipment Industry Association, the Electrical Automation Professional Committee of the Chinese Society of Automation, and the Electrical Control System and Device Professional Committee of the Chinese Electrotechnical Society, Shanghai Nancal Electric Co., Ltd., the advanced training course on inverter and its application jointly organized by Inverter World was successfully concluded.
