PetroChina Dushanzi Petrochemical's Tarim 1.2 million tons/year Phase II Ethylene and Supporting Green Low-Carbon Demonstration Project, China's first full-chain green and low-carbon ethylene project, achieved successful first-feed commissioning. Behind this achievement, over 20 Nancal Electric large-capacity medium voltage drives are operating reliably, ensuring safe and continuous production at this world-class petrochemical base.
A major milestone was achieved at PetroChina Dushanzi Petrochemical's Tarim 1.2 million tons/year Phase II Ethylene Project — China's first ethylene plant with fully electric-driven compressors using indigenous technology was officially commissioned. As the supplier of the core equipment, Nancal Electric provided a complete ultra-large capacity, high-reliability medium voltage drive system solution.
Nancal Electric has achieved significant milestones in the localization of AP1000 reactor coolant pump drives, nuclear power circulating pump drives, and high-temperature reactor main helium fan drives. Nancal Electric has won several major awards, further demonstrating its technical capabilities and industry contributions.
Nancal Electric supplies medium voltage drives for the newly commissioned Unit 3 at PipeChina's Guangzhou Compressor Station, continuing its long‑term role as a core localization partner for China's unified national pipeline network.
Nancal Electric completes full localization of eight imported RCP drives at Haiyang Nuclear Phase I, eliminating unplanned shutdowns and enhancing operational reliability with a "4-operation, 1-standby" drive system configuration.
Recently, the first in-service gas-to-electric compressor unit of PipeChina successfully completed its 72-hour trial operation and was officially commissioned at the Quzhou Station of Zhejiang Natural Gas Pipeline Company. All equipment of the project was fully localized, with two 23,500 kVA water-cooling medium voltage drives supplied by Shanghai Nancal Electric Co., Ltd. Nancal Electric contributed to the project's energy savings and emission reductions, supporting improvements in pipeline transmission capacity and green supply assurance.
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.
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.
Shanghai Nancal Electric Co., Ltd., in collaboration with Shandong Nuclear Power Company Ltd. (SDNP) and Shanghai Nuclear Engineering Research & Design Institute (SNERDI), has been honored with the Second Prize for Science and Technology Progress by the China Nuclear Energy Association (CNEA) for the joint project "Localized R&D and Application of Reactor Coolant Pump (RCP) Drives." The project team successfully developed China's First MV Drive for the Generation III AP1000 Nuclear Power Plant Reactor Coolant Pump with fully independent intellectual property, achieving a breakthrough in core technology localization. This accomplishment is of significant importance for enhancing the safety and reliability of nuclear power. The RCP Drive has been deployed for commercial operation and was included in the National Energy Administration's List of Major Technical Equipment in the Energy Sector in 2024.
As a leader in high-capacity medium voltage drives, Nancal Electric attended the 4th Petrochemical Procurement & Supply Chain Innovation Exchange Conference and delivered a technical presentation titled "High-Reliability Medium Voltage Drive Technology and Applications," sharing the company’s innovative achievements and practical experience in the petroleum and petrochemical sectors.
