The purpose of the following specification is to set forth the requirements of transformers for general use for the electrical distribution system of the City of Redding Electric Utility. It is the intent of these specifications to obtain for the City of Redding Electric Utility transformers of the best modern design, of proven performance, rugged, reliable and capable of remaining in service for many years without maintenance. The transformers shall be constructed with parts commonly available in the United States wherever practical. Only manufacturers with ten (10) years demonstrated experience in manufacturing distribution transformers of the type and size specified will be considered. The manufacturer shall have a minimum of five (5) years continuous market presence in the United States with the necessary infrastructure in place (service facilities, engineering support, and spare parts supply). Transformers built to foreign or international standards will not be allowed unless the manufacturer positively demonstrates to the City’s satisfaction that the transformers also meet all appropriate ANSI, NEMA, IEEE, and ASME standard requirements for power transformers in addition to those requirements in this specification.
