26、6 3.3.2 CONDUCTOR INSULATION A permissible overall performance level of voltage breakdown faults in primary insulation shall average not greater than one fault per 12,000 conductor meters (40,000 ft). All insulated conductors shall be continuously tested for insulation voltage breakdown faults durin

Engineering Information: 3.6 kv D.C. is recommended in determining compliance with the above requirement. The polyethylene primary insulation shall meet the re
28、quirements of REA Specification PE-200, “Polyethylene Raw Elaterial,“ for high density insulating grade material, Appendix C. The requirements shall apply to the basic resin, prior to the addition of the blowing agent. Crystalline propylene/ethylene copolymer material, which may be used as an altern
29、ate primary insulation shall meet the requirements of REA Specification PE-210, “Crystalline Propylene Ethylene Copolymer Raw Material“, Appendix A. The requirements shall apply to the basic resin, prior to the addition of the blowing agent. Primary insulation removed from or tested on the conductor
30、, from a finished cable, shall be capable of meeting the following performance requirements: Crystalline Propylene/ethylene Property Polyethylene Copolymer Tensile Strength minimum, kpa (psi) 10,342 (1,500) 12,410 (1,800) Ultimate Elongation percent, minimum 300 Cold Bend failures, maximum o/ 10 Shr
31、inkback maximum, mm (in.) 10 (0.375) 300 o/ 10 10, (0.375) The procedures for testing whether the insulation specimens are in compliance are described in the following paragraphs.

32、 the primary insulation, removed from the conductor, shall be tested in accordance with ASTM D 3633-76, except that the speed of jaw separation shall be 50 mm/min (2 in./min). NOTE: Quality assurance testing at a jaw separation speed of 50 cm/min (20 in./min) is permissible. Failures at this rate sh
33、all be retested at the 50 mm/min (2 in./min) rate to determine specification compliance. 3.3.2.2 Cold Bend Samples of the primary insulation shall be tested in accordance with ASTM D-1047-67, with the following exceptions : the polyethylene material shall be tested at -55 f l0C with the mandrel diam
34、eter of 3 times the outside diameter of the insulated conductor; the Crystalline propylene/ethylene copolymer material shall be tested at -YO Ie l0C with the mandrel diameter equal to the outside diameter of the insulated conductor. 3.3.2.3 Shrin kback: A minimum of one sample of each insulated wire
35、 from the cable shall be tested. Immediately prior to testing, specimens 70 cm (8 in.) long shall be cut from the center of a 1.5 m (5 ft) length and then reduced to 15 cm (6 in.) by trimming each end of the specimen. The 15 cm (6 in.) specimens shall be placed in a convection type circulating.air o
36、ven for 4 hours at the temperatures indicated. Shrinkback is defined as a total shrinkage of the insulation from both ends of the specimen.

37、ter processing conduct using the following cable conditioning and insulation test procedures. A short length section, approximately 30 cm (i ft), of cable shall be sealed at the ends And placed in an oven at a temperature of 68 f l0C for 8 hours for conditioning. The sample will then be allowed to e
38、quilibrate to room temperature for a total of 24 hours. After w - - EIA IS-43AA 88 3234600 0002411 9 W NQ-EIA/IS-43AA Page 8 equilibration, 1 sample shall be taken of each insulated conductor. The samples shall be wiped clean of grease and foreign objects using a dry cloth (without solvents). Each s
39、ample shall be individually tested by means of a differential scanning calorimeter (dsc) or by differential thermal analysis (dta). The sample must be clean and dry. The cell is cleaned by holding it at 400C for 10 minutes in nitrogen. The testing cell should be cleaned after standing overnight and
40、between testing of different formulations. The temperature scale should be adjusted according to the instrument instruction manual until the determined melting point of pure indium metal is 156.6OC at a heat rate of 5 per minute. Engineering Notes: Dupont 990 with DSC Cell: With the instrument in is
41、otherpal mode, calibrate the “starting temperature dial“ according to the instrument instruction manual. Alternately the dial may be set to a reading which results in a corrected thermocouple read-out of 190C. Perkin-Elmer DSC-1 or DSC-2: Run seve-al pure metal standards (e.g., indium, tin, lead, zi
42、nc) through their melting point at a heating rate of 5C per minute. Plot the melting temperatures and interpolate to find the correct set point for 190C. Repeated calibrations require only adjustments for the indium melt temperature. Prepare a clean aluminum dish by heating the pan in the flame of a
43、 fisher burner. Remove the pan from the flame and immediately cool in a gentle stream of air. Remove the insulation from the conductor. Flatten the resin LO about . 2/3 of its thickness (not critical). Trim the sample.to an approximate roundness, about 2 mm (0.08 in.) in diameter. The sample should
44、weigh approximately 1 to 2 mg. Position the sample in the center of the sterilized aluminum pan, cover with clean $316 stainless steel screen (40 mesh) and crimp the pan. Place the sample and pan in an instrument cell and flush it for 5 minutes with cylinder nitrogen at 60 k 10 cm3 per minute. Rapid
45、ly increase the sample temperature (20C per min.) from a 100C or lower initial temperature, to 190 4 loC. After 50 k 5 cm3 per minute oxygen flow and start time-base recording. Other flow rates of up to 150 cm3 per minute inclusive maximum, can be used. Record the rate of flow used. Oxygen should be
46、 equivalent to, or better than, 99.6 percent extra dry grade. The oxygen induction point shall be recorded as time zero, and the chart speed shall be sufficient to provide a clearly discernible slope at the start of the exothermic reaction. The test in the pure, dry oxygen atmosphere shall continue
47、until the exothermic peak is produced. The intersection of the tangent of the exothermic sloped line with the extended base line will be drawn. The time interval from time zero to this intersection point is read from the base line and recorded as the F y, e e a I EIA IS-43AA 88 3234600 0002432 O = N
48、Q-EIA/LS-43- Page 9 oxidative induction time. The insulation over the copper conductor shall be capable of providing a minimum oxidation induction time of 30 minutes. 3.3.4 CORE SEPARATOR TAPE A separator tape shall be applied longitudinally to physically separate the core into two compartments. Suc
49、cessive lengths of separator tapes may be joined during the manufacturing process by means of cold weld, electric weld, or soldering with a nonacid flux. The metal tape shall be coated on both sides with a dielectric protective coating. This protective coating shall cover the edge of the metal so that no bare metal is exposed. After the joining process the protective coating shall be restored so that it is continuous. The coated metal separator tape shall be tested for resistance to filling material by aging a one meter (3 ft) length of the tape
