BID - 28 MVA Power Substation Transformer 2009

The document contains specifications and instructions for the manufacturing and delivery of a substation transformer. It provides details on the materials, covering, and capacities of the binder that will hold the manuals and data for the equipment. The document includes guidelines for labeling the binders and emphasizes that the shipment of the equipment will only be considered complete once all required manuals and data have been received. Additionally, the document includes a sample transmittal form for submitting the manuals and data, as well as a typical instruction book cover. It also outlines a manufacturing and delivery schedule that the contractor must provide with their bid. The document further specifies the scope and standards that the transformer and equipment must conform to, including ANSI standards and NEMA guidelines. It provides the rating and specifications for the transformer, such as the number of phases, capacity, cooling method, coolant type, frequency, voltage levels, and sound level requirements. Furthermore, the document introduces a specific requirement related to the low voltage neutral, which is brought out through a 110 KV BIL tank-mounted neutral. This additional detail highlights the importance of ensuring proper neutral connectivity and protection in the substation transformer. Overall, the document serves as a comprehensive guide for manufacturers and contractors involved in the production and delivery of the substation transformer, providing them with the necessary specifications and instructions to meet the required standards and ensure the successful completion of the project.
