Today, the 10th National Petroleum and Chemical Electrical Technology Conference 2026, themed "Smart Power Empowers Green and Low-Carbon," was successfully held in Hefei. The conference was co-organized by Shanghai Nancal Electric Co., Ltd. Bringing together industry experts and representatives from leading enterprises, the event focused on electrical intelligence and green energy-saving technologies, aiming to address technical challenges and practical difficulties in the green and low-carbon transition of the industry.
Nancal Electric delivered a technical presentation titled Medium Voltage Drives Empowering Energy Saving, Carbon Reduction, and Safe & Stable Operation in the Petrochemical Industry. Drawing on the Nancal Electric's application cases in major projects across industries including oil, chemical, nuclear power and others, the presentation provided an in-depth explanation of the core value and practical effects of high-reliability variable frequency drive solutions in ensuring safe and continuous production and promoting energy saving and carbon reduction.
As a leader in high-power medium voltage drives in China, Nancal Electric has always been deeply committed to technology R&D, while establishing core technological strengths in high-power power electronics topologies, all-digital control platforms, speed sensorless vector control algorithms and high-reliability system design, providing critical equipment support for high-quality development in the industrial sector.
To date, Nancal Electric has achieved a cumulative total of over 200 units of its highly reliable, high-capacity water-cooling medium voltage drives, with the total capacity of its series of medium voltage drives exceeding 7500 MVA.
In terms of product portfolio, Nancal Electric's air-cooling medium voltage drives now cover a full range of output voltages (3 to 13.8 kV), currents (35 to 1000 A), and power ratings. Tailored to actual on-site user requirements, the drives are designed with a refined approach for different power ranges:
Low power range
Integrated design
Combining high power density with a compact cabinet footprint
Medium power range
Multiple cabinet sizes available for the same rating
Fully adaptable to flexible layout requirements in different industrial scenarios
High power range
Medium voltage pre-charging function as standard
Wide capacity coverage
Meeting a wider range of industrial application needs
The series deeply inherits the high-reliability technology DNA of the water-cooling medium voltage drives, maintaining consistent core control performance and long-term operational stability. At the same time, targeted optimization and upgrades have been carried out in key dimensions such as power cell structural design and high protection ratings, further enhancing the product's scenario adaptability and operational durability.
With core advantages including high reliability, high energy efficiency, easy installation, and simple maintenance, Nancal Electric's air-cooling medium voltage drives operate stably and continuously across a variety of complex operating conditions. They have been widely deployed in diverse industrial applications, earning high recognition and consistent praise from domestic and international customers.
