10) Cable Fabrication: The cable to be furnished under these Specifications shall be manufactured by using the triple extrusion method (true or tandem), applying the conductor shield, the insulation, and the insulation shield in one pass. 11) Conductor: The center conductor of the 750 kcmil cable shall be annealed uncoated compact round copper, in accordance with ICEA S-94-649 and ASTM B-496. The conductor shall be untarnished, bright, clean, and kept free of moisture, soot, and corrosion products. It will also be protected from abrasions and shall not be dragged on the ground at any time. 12) Conductor Shield: An extruded thermosetting, semiconducting shield shall be applied directly over the conductor. The shield shall be designed to firmly bond to the insulation but to strip easily and cleanly from the conductor. Shield average thickness and minimum thickness at any one point shall conform to ICEA- S-94-649 and AEIC CS8. The conductor shield material shall be ethylene propylene rubber (EPR) or approved equal. 13) Insulation: The cable insulation, which shall be extruded over the conductor shield, shall be made of high-quality, low dielectric loss, ozone and ultraviolet-resistant, ethylene propylene rubber (EPR). The insulation shall be designed for 105°C conductor normal operating temperature and shall meet all the requirements of ICEA S-94-649 and AEIC CS8. The ethylene content of the insulation must not exceed 72% by weight. The cable insulation shall have a thickness of 220 mils and shall meet all the dimensional, electrical, and physical requirements specified in ICEA- S-94-649 and AEIC CS8. The cable insulation shall be colored to contrast with the semiconducting shield layers. 14) Insulation Shield: An extruded thermosetting, semiconducting shield meeting the requirements ofICEA S-94-649, AEIC CS8 and CSA C68.5 shall be applied over the insulation. The insulation shield shall strip cleanly from the insulation and shall not require heat for its removal. The tension necessary to remove the insulation shield from the insulation at room temperature shall be between 8 pounds and 16 pounds. The insulation shield material shall be ethylene propylene rubber or approved equal. 15) Concentric Neutral Conductor: A concentric neutral conductor shall be installed over the insulation shield. The conductor shall consist of at least twenty-four (24) #10 AWG round, solid, uncoated copper wires per phase. 16) Cable Jacket: An encapsulating insulator jacket consisting of moisture-resisting, black, linear, lowdensity polyethylene shall be extruded over the concentric neutral conductor and fill the spaces between the wires. The jacket material shall be in contact with the insulation shield but shall strip freely from it. The cable jacket shall meet all the dimensional, electrical, and physical requirements specified in ICEA S-94-649 and AEIC CS8. 17) Markings: The outer surface of the cable jacket shall be durably marked throughout its length with the footage, manufacturer's name, insulation thickness inmils, type of insulation, conductor size and material, rated voltage, and year of manufacture. The above markings shall be repeated along the cable at regular intervals with unmarked surfaces not exceeding six inches. All character markings shall be at least 1/8 inch high. 18) Packaging: The completed cable shall be furnished and delivered in returnable metal reels not exceeding 84 inches in flange diameter and 54 inches in overall outside width, with a capacity of 1,880 feet per reel. Gross weight shall be below 13,000lbs. The minimum drum diameter of the reel shall conform to the requirements of NEMA WC 26. All returnable metal reels which carry a deposit will be returned to the Contractor or shipped to a specified destination freight collect. Contractor shall refund all reel deposits for all reels returned in good condition within two (2) years from date of delivery to the City. 19) Data Tabulation: The bidder shall furnish the data called for in the Data Tabulation Sheet.
