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.

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.

Storage is an energy infrastructure integrating the functions of seasonal peak regulation, emergency gas supply and national energy strategic reserve. As a key equipment supplier of compressor units, Nancal Electric has excellent on-site service technology and fast response, which has been highly praised by Petrochina Southwest Oil and gas Field Huangcaoxia Gas Storage Construction Project Department and Sichuan Huacheng Supervision Company. ​
