Extruded Nylon Thermoplastic Tinned Copper
Jacket Overall Insulation Stranded
Standard basic insulation color numbers are: Black: 0, Brown: 1, Red: 2, Orange: 3, Yellow: 4, Green: 5, Blue: 6, Violet: 7, Gray: 8, White: 9. The
insulation color code number, per MIL-STD-681, may be 1, 2 or 3 digits depending on the number or absence of stripes. The 1st number is color of
Insulation, 2nd number is color of first stripe; 3rd number is color of the second stripe. Example: White wire(9) + Red stripe(2) + Black stripe(0) makes a
color code number of “920”. That color number, “920” is appended to the part number. Sample part number might be “xxxxxx-xxx-920”
