The requirements for acq
2、uiring the product described herein shall consist of this specification sheet and MIL-DTL-24643. Construction, Non-Watertight First - Copper conductor, coated or uncoated (see table I for size). Second - Separator may be used at manufacturers option where required to provide free-stripping insulatio
3、n. Third - Thermoset insulation (see table I for thickness). Standard identification code shall be applied by Method 1 or Method 3. If identification Method 1 is used, the insulation color shall be black. Fourth - Three conductors cabled together with a lay in accordance with 3.4.4 of MIL-DTL-24643.
4、 Fillers may be used as necessary to form a firm well-rounded assembly. Fifth - An optional binder. Sixth - Cross-linked polyolefin jacket (see table I for thickness).
