PST Riddes - 2x 450MVA 220/220kV Phase Shifting Transformers

This tender from Swissgrid pertains to the procurement of two Phase Shifting Transformers (PST) for the Riddes substation. The scope of work encompasses the entire lifecycle of the transformers, including calculation, design, construction, manufacturing, testing, foundation transport, assembly, commissioning, and warranty. Each PST unit will consist of a series transformer and an excitation transformer, interconnected by fluid-filled lines to form a complete transformer set. The specified insulation level for the alternating voltage (Um) of the connections is 245 kV. The through-power capacity for each transformer set is rated at 450 MVA (Source - Load), designed for continuous operation. Detailed specifications regarding the power ratings and technical requirements are provided in the document "C100_Lastenheft_v10.pdf". This project is crucial for enhancing grid stability and power flow management within the Swiss transmission network, specifically at the Riddes location. Interested bidders are expected to demonstrate comprehensive expertise in high-voltage transformer technology and project execution.
