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.
