ELECTRICAL CONDUCTORS HIGHWAY LIGHTING 811.04
811.01 Description
This work co nsists of providing and installing electrical conductors to transmit and distribute electrical energy.
811.02 Materials
Provide materials in accordance with the following subsections: Material: Subsection: Building Wire and Cable 738.02 Underground Secondary Distribution Wire and Cable 738.02 Outdoor Aerial Neutral -Supported Secondary Distribution Wire and Cable 738.02
811.03 Equipment — Vacant
811.04 Construction Methods
A.Conductors in Conduit Complete the conduit system before installing the conductors. Provide enough slack in each conductor to allow at least 5 ft [1.5 m] at pole bases and at least 10 ft [3 m] at pull boxes.
B.Aerial Conductors Install aerial conductors in accordance with the National Electric Safety Code and the manufacturer’s recommendations for sag and t ension. Submit a copy of the cable manufacturer's charts, for each size and type of cable, to the Resident Engineer for approval of aerial conductor.
C.Splices and Taps Splice or tap the underground and indoor conductors at pull boxes, pole bases, contro l cabinets, junction boxes, or other weatherproof enclosures. Splice and tap outdoor aerial conductors as shown on the Plans. Do not pull splices into the conduit system. Provide the types of splices and taps required by the Contract. Seal, waterproof, and insulate insulated conductors in accordance with ANSI C 119.1 -2011, “Sealed Insulated Underground Connector System Rated 600 Volts.” Alternatively, complete Procedure 1 or Procedure 2.

1.Procedure 1 Make splices and taps using compression connectors . Apply at least three layers of rubber tape in uniform half -lap wrapping, or cover the joint with at least a ⅛ in [3 mm] layer of electrical insulating putty. Place at least three layers of high dielectric, high tensile strength, cold weather plastic ta pe in uniform, half -lap wrapping over the rubber tape or putty. Coat the layers with insulating paint.
2.Procedure 2 Use waterproof, self -insulating connections made of compression connectors and epoxy or gel cast splice kits or heat shrinking splice ki ts.
D.Fuse Holders and Fuses Make in -line or Y -type fuse holders as shown on the Plans. If required by the Contract, provide waterproof and self -insulating fuse holders with a quick disconnect breakaway feature on the load side. Install a Y -type fuse ho lder at the base of each pole or overhead sign structure with the properly sized fuse. If shown on the Plans, provide branch circuits with an in -line fuse holder and fuse.
E.Testing Test the installed electrical conductors in accordance with Section 801, “ Performance and Operational Tests for Highway Lighting and Traffic Signals .”
811.05 Method of Measuremen T — Vacant
811.06 Basis of Payment
The Department will pay for each pay item at the contract unit price per the specified p ay unit as follows: Pay Item: Pay Unit: ELECTRICAL CONDUCTOR Linear Foot [Meter] Include the cost of connectors, fuses, splices, and taps in the contract unit price for Electrical Conductor . HIGH MAST POLES 812.02 SECTION 812 HIGH MAST POLES
812.01 Description
This work consists of providing and installing high mast poles.
812.02 Materials
Design and provide all materials for high mast poles in accordance with the AASHTO Standard Specifications for Str uctural Supports for Highway Signs, Luminaires and Traffic Signals. Before starting high -mast lighting work, submit two (2) hardcopies of brochures for, and a schedule of, the proposed materials and equipment items for high -mast lighting work high mast pol es to the Resident Engineer. Include brand names, catalogue numbers, descriptions, cuts, diagrams, shop and design drawings, and calculations as required by the Contract. The Resident Engineer may waive submittal requirements if the materials and equipmen t are on the QPL. Verify the accuracy of the dimensions and details on the design drawings in accordance with Subsection 105.02, “Plans and Working Drawings.”
A.Structural Design Design high mast pole structures in acc ordance with AASHTO. Apply the following design parameters: Maximum pole deflection: no greater than 10 percent of the pole height; Yearly Mean Wind Velocity, Region C, (Vmean > 11 mph [4.9 m/s]) The Department may randomly check pole designs. Ensure the p ole manufacturer certifies the following in writing: The pole design was coordinated with the manufacturer of the lowering device design; The pole design is compatible with the installation of the high mast lowering device and luminaire; and The total syst em will function properly.
B.Fabrication of Steel Shafts Provide high -strength steel shafts in accordance with Section 812.02.D, “Mechanical Properties.” The Department will allow circular, many -sided shafts either the total length shown on the Plans, or in telescoping sections. Provide galvanized poles in telescoping sections only. Provide cold -formed shafts uniformly tapered from the largest diameter at the base to the smallest diameter at the top without reducin g the wall thickness. For shafts 120 ft [36 m] or shorter, provide no more than five telescoping sections. For shafts longer than 120 ft to 150 ft [36 m to 46 m], provide no more than six telescoping sections.
