Low Voltage Ultra-Thin Wall Primary Cable
This standard covers ultra-thin wall low voltage primary cable intended for use at a nominal system voltage of 60 VDC (60 VAC rms) or less in surface vehicle electrical systems. The tests are intended to qualify cables for normal applications with limited exposure to fluids and physical abuse. This standard covers SAE conductor sizes which usually differ from ISO conductor sizes.
SAE J1678 has been revised to; (1) remove the reference to an ignition coil in section 3.14 and redefine use as an insulated small conductor for signal, low current or power applications, (2) clarify cable types in Figure 1 as “not all types are commercially available”, (3) add a cross-linking test as shown in Figure 2 and section 6.17, (4) reformat Figure 5, (5) inserted Figure 13 to clarify the temperature and humidity cycles and transition zones, (5) removed Figure C1 from the document, (6) all figures; appendix and equation references were reviewed and added as required in the text.
