SCOPE The material defined by this specification is a stranded, vinyl covered low tension cable. The vinyl covering shall be 105 C classification. The in

3、dividual strands are tinned together after stranding. 2. APPLICATION This specification was released originally for material for the speed control. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requireme

4、nts For Production Materials (WSS-M99P1111-A). 3.1 WIRE QUALITY The strands of the conductors prior to stranding shall consist of ESF-M2L1-A, soft or annealed round bare copper wire. 3.2 CABLE CONSTRUCTION Stranded SAE No. Nominal Strand Conductor Area of Wire of Size Dia (approx) Conductor Size Wir

6、ter, max SAE 20 Gage 1.78 mm SAE 21 Gage 1.65 mm 3.3 INSULATION QUALITY The insulation material shall be a good grade vinyl chloride copolymer which will pass the following test requirements: The material shall adhere closely to, but strip readily from the conductors, leaving them reasonably clean a

7、nd in suitable condition for soldering. Insulation thickness shall be in accordance with 3.2.1 and shall be determined by measuring the diameter over the insulation, then removing the insulation and measuring the diameter of the conductor. Half of the difference of the two measurements shall be cons

8、idered as the wall thickness. 3.3.1 High Temperature Resistance 25 mm of the insulation shall be removed from each end of a 610 mm sample of the finished cable. The sample shall be suspended around a cylindrical mandrel having a diameter of 114 mm. Each end of the conductor shall have suspended from

9、 it a weight of 0.45 kg. This condition shall be maintained for 168 h at 135 - 137 C in a circulating air oven. When cool, the weight shall be removed from the specimen and it shall be taken off the mandrel, bent in the reverse direction around a mandrel of 76 mm diameter at a rate not to exceed one

10、 complete turn/minute and then subjected to the dielectric test (para 3.3.2). 3.3.2 Dielectric Test A specimen of the cable 610 mm long shall be formed into a loop. 25 mm of the insulation shall be removed from each end of the wire and the ends twisted together. The loop thus formed shall be immerse

11、d in water containing 5% salt by weight at room temperature, so that not more than 152 mm of each end of the specimen protrudes above the solution. After being immersed for 5 h and while still immersed, the specimen shall withstand the application of 1000 V (rms) at 60 Hz frequency between the condu

12、ctor and the water for 1 minute without rupture of the insulation. 3.3.3 Oil Resistance A specimen 610 mm long shall be immersed to within 38 mm from the ends in a mixture of equal parts of kerosene and engine lubricating oils at a temperature of 50 +/- 2 C for a period of 20 h. The sample shall the

13、n be removed from the solution, examined for deterioration of the insulating compound, and gaged for swelling. ENGINEERING MATERIAL SPECIFICATION ESF-M1L110-A Page 3 of 3 Copyright 2003, Ford Global Technologies, Inc. The outside diameter of the insulation of the cable shall not increase more than 1

14、5%. The sample shall then be bent around a mandrel 76 mm in diameter and checked for cracking; after the bend test the cable shall pass the dielectric breakdown test (para 3.3.2). 3.3.4 Cold Resistance A straight specimen shall be reduced to a temperature of -40 C at a rate not to exceed 50 C/min. A

15、fter maintaining this temperature for 3 h and while still at this low temperature, the cable shall be wrapped around a mandrel 76 mm in diameter for 180 at the uniform rate of one turn in 10 s. The insulation shall be removed for a distance of 25 mm from each end of the specimen and the specimen sub

16、jected to the dielectric test (para 3.3.2). 3.3.5 Flame Test A 610 mm specimen shall be suspended in a vertical position within a partial enclosure which allows a flow of sufficient air for complete combustion but is free from drafts. The tip of a 50 mm gas flame with an inner cone one-third its hei

17、ght shall then be applied to the end of the specimen for 15 s. After removal of the flame the specimen shall not continue to burn for more than 30 s. 3.3.6 Abrasion Resistance, min 152 mm of tape (SAE J 1128, Bracket A, 0.45 kg weight) 3.4 TINNING QUALITY Strip 50 mm of insulation from the end of the wire. Bend 90. There shall be no evidence of cracking or wire separation.
