The technical sections referred to herein are those specification sections that describe products, installation procedures, and equ
24、ipment operations and that refer to this section for detailed description of submittal types. c. Vertical assembly: A vertical assembly is a pole, tower or other such support, mounting hardware, arms, brackets and the load. Load can be a luminaire, siren, loudspeaker or other device. All components
25、of a vertical assembly will be rated by the manufacturer to withstand 217_ kilometer/hour 135_ mph wind loading.1.3 SUBMITTALS*NOTE: Review Submittal Description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the proj
26、ect.The Guide Specification technical editors have designated those items that require Government approval, due to their complexity or criticality, with a “G.“ Generally, other submittal items can be reviewed by the Contractors Quality Control System. Only add a “G” to an item, if the submittal is s
27、ufficiently important or complex in context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Reside
28、nt Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office. Codes following the “G“ typically are not used for Navy, Air Force,
29、and NASA projects.Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects.*Government approval is required for submittals with a “G“ designation; submittals not having a “G“ designation are for Contractor Quality Control approval.f
30、or information only. When used, a designation following the “G“ designation identifies the office that will review the submittal for the Government.

When the enclosure integrity of such equipment is specified to conform with IEEE C57.12.28 or IEEE C57.12.29, such as for pad-mounted transformers
35、and pad-mounted SF6 switches, provide self-adhesive warning signs on the outside of the high voltage compartment door(s). Provide decal signs with nominal dimensions of 178 by 255 mm 7 by 10 inches. Print the legend “DANGER HIGH VOLTAGE“ in two lines of nominal 50 mm 2 inch high letters. Show the wo
36、rd “DANGER“ in white letters on a red background and the words “HIGH VOLTAGE“ in black letters on a white background. Use Panduit decal No. PPSO710D72 or approved equal. b. When such equipment is guarded by a fence, mount signs on the fence. Provide metal signs having nominal dimensions of 355 by 25
37、5 mm 14 by 10 inches with the legend “DANGER HIGH VOLTAGE KEEP OUT“ printed in three lines of nominal 75 mm 3 inch high white letters on a red and black field.2.1.12 Dry-Type Distribution TransformersGeneral purpose dry-type transformers with windings 600 volts or less are two-winding, 60 hertz, sel

High
39、 performance coatings are specified for all outdoor applications because ultraviolet radiation will break down most standard coatings, causing a phenomena known as chalking, which is the first stage of the corrosion process.
