2、E, PRIMARY LOW TENSION ESB-M1L54-A 105 C - CHLOROSULFONATED POLYETHYLENE INSULATED 1. SCOPE The material defined by this specification is a low tension stranded cable. The cable is similar to SAE J 1128 Type HTS (heavy duty thermoset). The insulation will have a 105 C classification. NOTE: The assem
3、blers of electrical wire harnesses shall use the bulk wire suppliers as shown in the Ford Motor Company Materials Approved Source List. 2. APPLICATION The material specified is to be used primarily for fusible links in automotive electrical harnesses. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PR
4、ODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 CONDUCTOR 3.2.1 Unless otherwise specified on the component drawing, the individual strands of the conductor shall be bare or tin-coated copper (
5、soft or annealed) conforming to, respectively, ASTM B3 or ASTM B33, except strand dimensions. These dimensions shall be controlled to yield the cross-sectional area listed for the conductor of the finished cable per Table 1. Conductor area shall be determined by measuring individual strand diameters
6、 and calculating the sum of the individual strand areas. As an alternate method, conductor area may also be determined in accordance with ASTM B263. 3.2.2 The strands shall be bunched per ASTM B174. The maximum lay length shall be as specified in ASTM B174 Table 2, Column A. Conductor strand count s
7、hall comply with Table 1. Missing strands are not allowed. 3.3 SEPARATOR A suitable barrier between the insulation and the copper conductor shall be used that will prevent any adverse or detrimental interaction from taking place between those two components. Unless otherwise indicated on the compone
8、nt drawing, this barrier will consist of an inner sheath or a tin coating as specified below. In either case, the insulation (and inner sheath, if used) shall strip readily from the conductors, leaving them reasonably clean and in suitable condition for terminating. 3.3.1 If bare copper wire is empl
9、oyed, an inner sheath or separator shall be applied between the conductor and the insulation. 3.3.2 If tinned copper wire per ASTM B33 is employed, the use of the separator as specified in 3.3.1 is optional.

10、 Ford Global Technologies, LLC Page 2 of 4 3.4 INSULATION 3.4.1 The insulation material shall be chlorosulfonated polyethylene. The color of the insulation shall be specified on the engineering drawing of the component utilizing this material. Base color codes shall correspond to SAE J 1128. 3.4.2 I
11、nsulation thickness shall comply with the requirements of Table 2. Insulation thickness shall be measured in accordance with ANSI/UL-1581, Reference Standard for Electrical Wires, Cables, and Flexible Cords, Paragraphs 240 through 250.11. A 0.51 mm diameter pin will be used for determining minimum i
12、nsulation thickness at any point. 3.5 CABLE QUALITY (TESTS) The following tests: Insulation Physical Properties Test, Dielectric Test, Cold Bend Test, Oil Absorption Test, Overload Test, Short Circuit Test, and Pinch Test correspond respectively to sections 4.2, 4.3, 4.4, 4.6, 4.7, 4.8, and 4.9 of S
13、AE J 1128. Results of these tests shall comply with the requirements of SAE J 1128, type HTS. The tests listed below shall be conducted in addition to the tests listed above. 3.5.1 Controlled Current Test Remove 13 mm of insulation from each end of a 300 mm specimen of finished cable. Eyelet termina
14、ls of the proper strand grip size shall be crimped and soldered to each end of the specimen. The specimen shall then be subjected to the overload values specified in Table 3. Each specimen must fail “open“ with no evidence of flame. 3.5.2 Flame Test Flame Test shall be conducted per SAE J 1128, Sect
15、ion 4.5 except that the specimen shall be suspended vertically.
