    Brief

    This contract opportunity involves the retrofit of machine transformers Ud2 and Uk2. The work includes the maintenance and repair of frequency-sensitive network coupling converters, which consist of two rigidly coupled rotating electrical machines: a doubly-fed three-phase asynchronous motor (50Hz) with GTO power control and a single-phase synchronous generator with DC excitation. The project will require transporting the two transformers, Ud2 (50Hz, 40 MVA, ELIN) and Uk2 (16.7Hz, 50 MVA, ELIN), for external factory revision as part of the planned recommissioning of the converter plant in Hamburg-Harburg. Suppliers interested in this opportunity should be prepared to provide the necessary services for the repair and maintenance of these transformers.
