• Application of Nancal Medium Voltage Drive in Redundant Retrofit of Propylene Compressors

  In a chemical gasification plant, the propylene compressor plays a crucial role with high demands for operational reliability and stability. Equipment failure can have severe impacts on the plant and downstream production. The plant originally used an imported medium-voltage drive, but its failure rate has been increasing. A significant failure, especially one that cannot be quickly repaired, could halt gasification operations, disrupt downstream production, and lead to substantial economic losses. After extensive research and technical discussions, the user selected Shanghai Nancal’s medium-voltage drive for hot standby, enabling the redundant automatic switching technology of NC HVVF to resolve issues caused by failures in the original imported drive and ensure uninterrupted production.

• Application of Nancal Electric MV Drives in High-Speed Permanent Magnet Direct-Drive Systems for Steam-to-Electric Retrofit Project of Compressors in the Chemical Industry

  A well-known domestic chemical enterprise planned to implement an energy-saving, emission-reduction, and capacity-expansion project for its polycarbonate production unit. This included converting the originally steam-driven MVR steam compressor to electric drive. The MVR steam compressor system was originally driven by a high-speed steam turbine (referred to as the steam turbine), directly connected to the drive shaft of the high-speed centrifugal compressor. The NC HVVF series medium voltage drives provided by Nancal Electric delivered excellent high-frequency drive performance and system safety control performance for the high-speed PMSM in this MVR steam compressor "steam-to-electric" retrofit project of a polycarbonate production unit, providing highly reliable and sustainable technical support for the project retrofit.

• National Energy Administration Added "Non-Energy Third-Generation Nuclear Power Reactor Coolant Pump Drive" to Major Technical Equipment List

  The National Energy Administration officially added the "Non-Energy Three-Generation Nuclear Power Reactor Coolant Pump (RCP) Drive" to its list of major technical equipment in the energy sector. The Non-Energy Three-Generation Nuclear Power AP1000 RCP drive serves as the sole power supply for the motor. Its reliable operation is crucial to the stability, availability, and overall performance of the nuclear power plant. To address the supply chain bottleneck in this critical equipment, Shanghai Nancal Electric, Shandong Nuclear Power and Shanghai nuclear engineering R&D institute collaboratively developed a 10 kV/ 50 Hz input, 6.9 kV/ 60 Hz output, 10,500 kVA rated capacity reactor coolant pump drive. Beyond the energy sector, Nancal has also made significant "first set" strides in industries such as chemicals, mining, and energy storage.
