Marine Generator / Alternator · Power Generation
Stamford/Cummins PI7 1250kVA 690V 50Hz is listed as a Marine Generator / Alternator within the Power Generation category. It is typically installed in the engine room or generator room, coupled to a prime mover and connected to the vessel’s main or emergency electrical distribution system. Its engineering role is to convert mechanical shaft power into electrical power for shipboard consumers. The complete model designation should be retained when matching drawings, certificates, service information and spare parts because neighboring variants may differ in configuration even when they share the same equipment family. The exact shipboard arrangement and interfaces remain installation-specific and should be checked against the vessel’s approved drawings and equipment documentation. Where an operating value, tolerance, wear limit or setting is not explicitly stated in the source data, refer to the manufacturer documentation for the exact figure.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.
