DRY-TYPE SERVICE TRANSFORMER

PART 1 GENERAL

1.1 GENERAL INFORMATION

The Cole Rivers Hatchery electrical substation is to be designed, assembled and tested by one manufacturer. The Substation Manufacturer is to use these drawings and specifications as a guideline to complete their design, assembly and testing. The final design is to be approved by the Government.

The substation is to be completely designed, assembled and tested at the Substation Manufacturer's factory and shipped to the Cole Rivers site as a complete unit or as factory designed modules that the Substation Manufacturer is to assemble on the Government supplied concrete pad. The Substation Manufacturer's scope of work ends after the substation is unloaded from the Substation Manufacturer's delivery truck, craned on to the Government supplied concrete pad or if in modular pieces is connected together yielding a complete ready to use substation. The Government realizes size of the equipment and realizes that it may have to be shipped in sections due to shipping restrictions on the Oregon highway systems using standard trucking. The Substation Manufacturer is to minimize the amount of assembly at the site.

This section specifies the design, fabrication, assembly, wiring, and factory testing of the 13.8kV to 480 volt station service transformer. This transformer is one part of three sections that make up the Cole Rivers Substation.

The two other associated sections of this substation are:

480 VOLT SWITCHGEAR

03/22

PART 1 GENERAL

1.1 SUMMARY

The Cole Rivers Hatchery electrical substation is to be designed, assembled and tested by one manufacturer. The Substation Manufacturer is to use these drawings and specifications as a guideline to complete their design, assembly and testing. The final design is to be approved by the Government.

The substation is to be completely designed, assembled and tested at the Substation Manufacturer's factory and shipped to the Cole Rivers site as a complete unit or as factory designed modules that the Substation Manufacturer is to assemble on the Government supplied concrete pad. The Substation Manufacturer's scope of work ends after the substation is unloaded from the Substation Manufacturer's delivery truck, craned on to the Government supplied concrete pad or if in modular pieces is connected together yielding a complete ready to use substation. The Government realizes size of the equipment and realizes that it may have to be shipped in sections due to shipping restrictions on the Oregon highway systems using standard trucking. The Substation Manufacturer is to minimize the amount of assembly at the site.

This section specifies the design, fabrication, assembly, wiring, and factory testing of the 480 volt station service switchgear. This switchgear is one part of three sections that make up the Cole Rivers Substation.

The two other associated sections of this substation are:

261216.0025 DRY-TYPE SERVICE TRANSFORMERS

261301.0025 MEDIUM-VOLTAGE, METAL-ENCLOSED SWITCH-BREAKERS
