834.01 Description
This work consists of providing and installing electrical conductors for traffic signal systems.
834.02 Materials
Provide materials in accordance with the following subsections: Material: Subsection: Traffic Signal Wire and Cables 738.01 Shielded Loop Detector Lead -In Cable 738.01
834.03 Equipment — Vacant
834.04 Construction Methods
Avoid damaging the conductor and the insulation during installation. Replace damaged conductors at no additional cost to the Department.
A.Traffic Signal Electrical Cable Install traffic signal electrical cable from the heads on each traffic signal pole to the traffic signal controller. Place the electrical cable in conduit from the traffic signal pole to the controller. Provide electrical cable with the number of conductors and at least one spare conductor as shown on the Plans.
B.Shielded Loop Detector Lea d-In Cables Place the shielded loop detector lead -in cables in conduit from each loop detector pull box to the traffic signal controllers. At each loop detector pull box, splice the loop wire or the sensing element lead to the loop detector lead -in cable with a waterproof, self -insulating connection using soldered connections and epoxy or gel cast splice kits as shown on the Plans.
C.Underground Conductors in Conduit Complete the conduit system before installing the conductors. Provide slack in each cond uctor at the pole bases, pull boxes, and cabinets, as approved by the Resident Engineer.
D.Underground Splices Splices in traffic signal conductors at the pole bases, terminal block, or controller cabinet are allowed.
E.Testing Test the installed traffic signal and detector lead -in conductors in accordance with Section 801, “Performance and Operational Tests for Highway Lighting and Traffic Signals.”
