REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1 CABLE SIZE Shall not exceed SAE limits for type
4、 SGR cable. 3.2 CABLE QUALITY Shall meet all the requirements listed herein and must be equal to the original approved samples. 3.3 CABLE CONSTRUCTION The cable shall consist of 322 strands (nominal) of # 25 gage round wire layed in rope construction and served with 0.08 mm minimum paper or polyeste
5、r film insulating tape with 12 1/2 % minimum overlap. Absolute minimum number of strands at any one time to be 315. No individual group is to contain more than 20% of the total strands. Optional construction of this cable shall allow 259 strands (nominal of # 24 gage round wire, with 252 strands abs
6、olute minimum. Construction, serving and maximum strands per group are the same as previously described. Minimum area is 48.96 mm23.4 WIRE QUALITY The conductor strands prior to stranding or bunching shall consist of bare ESF-M2L1-A, soft or annealed round copper wire. ENGINEERING MATERIAL SPECIFICA

8、54 micro ohms/m 3.8 PHYSICAL AND ELECTRICAL PROPERTIES Three samples of cable are required. One for each of the high temperature, low temperature and oil absorption tests. All samples are subjected to the dielectric breakdown test at the completion of their respective tests. These samples are 0.6 m
9、in length with 25 mm of insulation stripped from both ends. 3.8.1 High Temperature Resistance No fracture or splitting of the insulation Test Method: Suspend sample over a 254 mm mandrel with a 2.72 kg weight at each end. Soak 121 +/- 2 C for 120 h in a circulating air oven. Cool to 23 +/- 2 C, remo
10、ve the weight and bend the sample around the mandrel in a reverse direction at a rate not exceeding 1 turn per minute until a 180 bend is completed. 3.8.2 Low Temperature Resistance No fracture or splitting of the insulation Test Method: Reduce temperature of a straight piece of sample to - 34 C at
11、a rate not to exceed 68 C per minute. Hold for 3 h and then wrap around a 254 mm mandrel for 180 at a rate of 1 turn per 10 s. 3.8.3 Oil Absorption Resistance Cable dia shall not increase more than 15% nor shall the insulation fracture or split Test method: Immerse sample to within 38 mm from the en
12、d into a solution of 50% kerosene and 50% SAE 10W engine oil for 20 h at 49 +/- 2 C. Wrap sample around a 254 mm mandrel for 180 . 3.8.4 Dielectric Resistance No rupture of the insulation Test Method: Join exposed ends of sample and immerse loop to within 150 mm of ends in a 5% salt bath ( salt content by weight at 27 C). Soak 5 h and then apply 500 V (RMS) 60 cps (Hz) between sample conductor and salt bath for 1 minute.
