Concentric stranded conductors shall conform to ASTM B231 for Class B stranding. Conductor Shield: 1. An extruded insulating or semi-conducting shield meeting the applicable requirements of Part 3 of ANSI/ICEA S-94-649 shall be provided. The minimum point thickness shall be in accordance with Table 3-1. Insulation: 1. Insulation shall be ethylene propylene rubber (EPR) which meets all requirements of ANSI/ICEA publication S-94-649. 2. The insulated cable shall fully comply with applicable provisions of current AEIC Cable Specification No. CS8 including the limits on voids and contaminants, as per section D.1, method of examination per section G, and frequency of sampling as per ANSI/ICEA S-94-649 Table 9-5. 3. 4. D. The nominal thickness of the insulation shall be 220 mils. The minimum and maximum thickness at any point shall be within the guidelines of Table 4-11 per ANSI/ICEA S-94-649. Insulation Shielding: 1. 2. 3. 4. 5. 6. 7. E. A semi-conducting layer meeting the requirements of section 5 of ANSI/ICEA S-94-649 shall be extruded tightly over the insulation to serve as an electrostatic shield. The shield compound shall be compatible with the insulation. The voids and protrusion limits shall be in accordance with sections 5.3 and 5.4 of ANSI/ICEA S-94-649. The thickness of the extruded insulation shield shall be in accordance with table 5-1 of ANSI/ICEA S-94-649. The shielding shall be applied such that all conducting material can be easily removed without externally applied heat. Stripping tension values shall be in accordance with the applicable requirements of part 5.4 of ANSI/ICEA S-94-649. The insulation shielding shall meet all applicable tests of Table 9-5 of ANSI/ICEA S-94-649. Concentric Neutral: 1. 2. 3. F. A concentric neutral of annealed copper wires shall be spirally wound over the insulation shielding with uniform spacing between wires, in accordance with ASTM B3. The number, size, and shape of wires shall be as specified in the Bid. The length of lay of the neutral wires shall be not less than 6 nor more than 10 times the diameter over the concentric wires. Outer Jacket: 1. An insulating black linear low density polyethylene layer meeting the requirements of ANSI/ICEA S-94-649, Table 7-1 shall be extruded directly over the insulation shield and concentric neutral wires. The jacket shall fill the interstice area, leaving no voids. 2. 3. 4. G. The jacket shall be applied such that the neutral wires are equally spaced and they shall remain in intimate contact with the underlying extruded insulation shield. The jacket shall be free stripping from the insulation shield and neutral wires without applying external heat. The minimum and maximum thickness at any point of the jacket over metallic neutral wires or straps shall be per ANSI/ICEA S-94-649, Table 7 10. Testing: 1. 2. H. The following tests shall be performed on all lengths of cable shipped on this order: a. b. c. d. e. A cold bend test shall be performed in accordance with the appropriate provisions of ANSI/ICEA S-94-649. A spark test shall be performed in accordance with part 7.3.1 of ANSI/ICEA S-94-649 on all cable prior to its being wound on shipping reels. The manufacturer shall measure each length of cable supplied to determine compliance with the dimensional requirements in Table 2-6 of the appropriate AEIC specification. The manufacturer shall perform an apparent discharge test in accordance with ANSI/ICEA S-94-649 except with a maximum allowable discharge of 5 picocoulomb to full test voltage of 200 volts/mil. The manufacturer shall perform an A.C. Voltage Withstand test in accordance with ANSI/ICEA S-94-649. The manufacturer shall provide certified test reports on all of the above tests at the time of cable shipment. Markings: 1. The cable shall have suitable markings on the outer surface of the jacket at regular intervals to indicate the manufacturer, conductor size, type of insulation, type of conductor, voltage rating, and year of manufacture. 2. Markings shall also be applied sequentially for length and the required NESC direct buried electric cable symbol. 3. I. Marking shall include the use of multiple red stripes equally spaced around the cable. Shipping: 1. 2. 3. 4. 5. 6. J. Cable shall be shipped on non-returnable reels in lengths as specified in the Bid. The quantity of cable specified in the Bid shall not be exceeded. Reels shall be numbered by manufacturer for proper record keeping. Watertight seals shall be applied to all cable ends to prevent the entrance of moisture during transit or outside storage. Reels used for shipment shall be in good condition and free of sharp projections that would damage the cable. The drum shall be wrapped with heavy corrugated paper or equivalent prior to reeling cable. The cable ends shall be secured to the reel in a manner to prevent cable damage and unreeling during shipment. The inside end shall be water sealed and secured to prevent "walkout" during unreeling. The manufacturer shall be responsible for any damage resulting from improper packing, sealing or blocking of the reels during transit. Identification tags for all reels shall be a weather-resistant tag firmly affixed to both the inside and outside of one flange. Reel tag information shall include: a. b. c. d. e. f.
