5、01Reaffirmed 2016-03 Superseding J2549 JAN2012 Single Conductor Cable for Heavy-Duty Applications - Truck and Bus RATIONALE J2549 has been reaffirmed to comply with the SAE five-year review policy. FOREWORD This document is intended as a supplement to the SAE J1127 and SAE J1128 Standards as a means
6、 of assuring the dimensional and performance needs associated with the unique demands of heavy-duty truck, trailer and converter dolly electrical systems. 1. SCOPE This SAE standard establishes the minimum construction and performance requirements for single conductor cable for use on trucks, traile
7、rs and converter dollies. 2. REFERENCES 2.1 Applicable Documents The following publications form a part of this specification to the extent specified herein.

DEFINITIONS Refer to the definitions contained in SAE J1127 and SAE J1
10、128. 4. GENERAL 4.1 Cable Types Due to the variation in the performance demands of cables used in different applications within the truck-trailer system, this document addresses various types of cables, determined by their mode of installation and working environment. These are summarized in SAE J11
11、27 and SAE J1128. 4.2 Identification Packaging containing cable conforming to this document shall be identified with the manufacturers identification, and shall be identified with SAE J2549 along with the cable type as described in SAE J1127 and SAE J1128. The cable itself is not to be marked as thi
12、s may conflict with circuit identification marking. 5. GENERAL SPECIFICATIONS 5.1 Conductors 5.1.1 Material All conductors shall be of stranded, soft-annealed copper, complying with ASTM B 3, SAE J1127 and SAE J1128. The surface finish shall be sufficiently free of imperfections to enable effective
13、terminal crimping and splicing. 5.1.2 Cross-Sectional Area The cross-sectional area of stranded conductors shall conform to the values specified in SAE J1127 and SAE J1128. Where a higher current-carrying capacity is required, the user may specify the larger cross-sectional area such as that outline
14、d in SAE J2394, (which covers three popular conductor sizes), after consideration of the effect on terminal crimp dimensions and connectors. 5.1.3 Stranding The individual strands contained within a conductor shall be of the same nominal diameter. The number of strands is dependent on the flexibilit
15、y and flex-life requirements for specific applications with a greater number of strands used in applications involving repeated flexing. 5.1.4 Conductor Splicing If required, conductor splicing shall meet the requirements outlined in SAE J1127 and SAE J1128 as well as those noted below. 5.1.4.1 Sing
16、le strand splices are not to be closer together than 20 times the conductor diameter in a bunched or concentric stranded conductor and 200 times the conductor diameter in a rope-lay construction and there shall be no more than three single strand splices per 3 m of conductor. SAE INTERNATIONAL J2549
17、 MAR2016 Page 3 of 4 5.1.4.2 Whole conductor splices shall not exceed a frequency of one splice per 30 000 m of cable. 5.2 Insulation 5.2.1 Material Physical Properties The physical properties of the insulation for each cable type shall comply with the requirements as outlined in the “Mechanical Pro
18、perties” section of SAE J1127 and SAE J1128. 5.2.2 Application Insulation shall be applied in compliance with SAE J1127 and SAE J1128. The surface finish shall be free of imperfections such as indentations, voids, nicks, cuts and roughness and the eccentricity and perimeter of the cable shall be suf
19、ficiently uniform to enable the effective sealing of standard connectors. 5.2.3 Insulated Conductor Outside Diameter The outside diameter of each insulated conductor shall be measured in accordance with the methods outlined in SAE J1127 and SAE J1128. The mean of the diameter readings shall determin
20、e the finished insulated conductor diameter and shall be in accordance with SAE J1127 and SAE J1128 except where identified in Table 1. 5.2.4 Wall Thickness The minimum wall thickness at any point shall be measured in accordance with the method outlined in SAE J1127 and SAE J1128. All individual wal
21、l thickness values must be in accordance with SAE J1127 and SAE J1128 except where identified in Table 1. 6. TESTS 6.1 Test Methods All tests shall be performed in accordance with the methods outlined in SAE J1127 and SAE J1128. 6.2 Performance Requirements Cable shall comply with all of the perform
22、ance and durability requirements outlined in SAE J1127 and SAEJ1128. 7.
