10-3.05 CONDUIT <br /> Conduit to be installed underground shall be Type 3 unless otherwise specified. Detector termination conduits shall be <br /> Type 3. <br /> The conduit in a foundation and between a foundation and the nearest pull box shall be Type 1. <br /> Conduit sizes shown on the plans and specified in the Standard Specifications and these special provisions are referenced <br /> to metallic type conduit. When rigid non-metallic conduit is required or allowed,the nominal equivalent industry size shall <br /> be used as shown in the following table: <br /> Size Designation for Metallic Type Conduit -Equivalent Size for Rigid Non-metallic Conduit <br /> 21 20 <br /> 27 25 <br /> 41 40 <br /> 53 50 <br /> 63 65 <br /> 78 75 <br /> 103 100 <br /> After conductors have been installed,the ends of conduits terminating in pull boxes, service equipment enclosures,and <br /> controller cabinets shall be sealed with an approved type of sealing compound. <br /> to-3.06 CONDUCTORS AND WIRING <br /> Splices shall be insulated by"Method B"or,at the Contractor's option,splices of conductors shall be insulated with heat- <br /> shrink tubing of the appropriate size after thoroughly painting the spliced conductors with electrical insulating coating. <br /> The Contractor shall replace conductors and cables damaged before, during or after installation by scraping, denting or <br /> other means,at the Contractor's expense. <br /> SIGNAL INTERCONNECT CABLE. <br /> Signal Interconnect Cable(SIC)shall be the 6-pair type. <br /> TELEPHONE CABLE <br /> Telephone cables shall be installed between field elements,controllers and Telephone Demarcation Cabinets, as shown <br /> on the plans and specified in these special provisions. <br /> Telephone cables shall meet the requirements of RUS Specification PE-39 and the following: <br /> A. Conductors shall consist of a solid wire of plain annealed high conductivity copper, smoothly drawn, circular in <br /> section, uniform in quality, free from defects and having a conductor size number 19 AWG. Conductors shall be <br /> insulated with colored,high density polyethylene jackets. <br /> B. Insulated conductors shall be uniformly twisted to form pairs. The twisted length of pairs shall vary to minimize <br /> cross talk. Non-hygroscopic dielectric tape shall be wrapped around insulated pairs. A laid up core shall be <br /> wrapped with aluminum tape and bonded with an overlap to provide 100 percent shielding. Black,high molecular <br /> weight, medium or low density, polyethylene jackets shall be extruded over shields. Filling compound materials <br /> used in cables shall not support galvanic action. <br /> Cables shall be color-coded using REA standard color codes. <br /> Testing <br /> The Contractor shall provide testing and documentation required to establish approval and acceptance of cables, <br /> installation and operation during the system integration testing. <br /> Cables shall be tested at the factory to ensure the cable complies with the manufacturer's specifications. <br /> The Contractor shall measure and record the continuity and insulation resistance of cable pairs in individual cable length <br /> after installation and submit the results to the Engineer. <br /> System integration testing shall be performed to ensure that tel <br /> cables perform as specified when used in <br /> operation with installed equipment. <br /> Contract No. 10-OM7104 <br /> 178 <br />
